Building with Safety in Mind: Exploring the Benefits of Fire Retardant Materials in Construction

October 13, 2023/in Fire Protection, News /by James

In the realm of construction, safety is paramount. As architects and builders continue to innovate, integrating fire retardant materials into construction practices has become a crucial aspect of ensuring the longevity and safety of structures. In this post, we delve into the significance of fire retardant materials, their applications, and the positive impact they have on the safety and resilience of modern constructions.

Understanding Fire Retardant Materials
Fire retardant materials are specifically designed to slow down or inhibit the spread of flames and reduce the combustibility of surfaces. These materials play a pivotal role in enhancing the fire resistance of buildings, providing valuable time for evacuation and minimising property damage in the event of a fire.
Applications in Construction
Fire retardant materials find applications in various components of a building, including structural elements, insulation, cladding, and interior finishes. By incorporating these materials into construction, architects and builders enhance the overall fire safety of the structure, meeting stringent building codes and regulations.
Enhanced Fire Resistance
The primary benefit of fire retardant materials is their ability to enhance the fire resistance of construction materials. From timber and steel to insulation and coatings, these materials significantly reduce the risk of fire-related incidents, offering a higher level of protection for both the occupants and the structure itself.
Compliance with Building Codes
Building codes and regulations often mandate the use of fire retardant materials in specific applications. By incorporating these materials, construction projects not only meet legal requirements but also contribute to the overall safety and well-being of the community.
Extended Escape Time
One of the key advantages of using fire retardant materials is the extension of the time available for occupants to evacuate a building in the event of a fire. This can be critical in emergency situations, allowing for a safer and more orderly evacuation process.
Preservation of Property
Beyond human safety, fire retardant materials also contribute to the preservation of property. By slowing down the spread of flames and reducing the intensity of a fire, these materials help minimise damage, resulting in lower repair and reconstruction costs for property owners.
Innovation in Fire Retardant Technologies
As technology advances, so does the field of fire retardant materials. Ongoing research and development efforts continue to bring forth innovative solutions that not only improve fire resistance but also address environmental concerns and sustainability in construction.

In a world where safety is paramount, the integration of fire retardant materials in construction is a proactive step toward creating resilient and secure structures. At Broadsword, we recognise the significance of these materials in safeguarding lives and property. As we build for the future, our commitment to incorporating the latest advancements in fire safety remains unwavering, ensuring that our constructions stand tall, not only in form but also in the face of unforeseen challenges.

As the problem with RAAC concrete being used in schools intensifies, what are the issues?

September 6, 2023/0 Comments/in Home Page news feed, News /by joannevickers

What is RAAC?

Reinforced Autoclaved Aerated Concrete (RAAC), also known as Reinforced AAC, is a building material that combines the properties of Autoclaved Aerated Concrete (AAC) with reinforcement to enhance its structural strength. It is a lightweight, precast concrete alternative made from sand, cement, lime, and aluminum powder. The aluminum powder creates tiny bubbles in the concrete during a chemical reaction, resulting in a highly porous and lightweight material. AAC is known for its excellent thermal insulation properties, low density, and ease of construction.

In the context of RAAC, reinforcement typically refers to the addition of steel reinforcement, such as rebars (reinforcing bars), mesh, or other structural elements, within the AAC panels or blocks. Reinforcement is added to improve the material’s tensile strength and structural stability, making it suitable for a wider range of structural applications.

The combination of AAC and reinforcement offers several advantages:

Structural Strength: The inclusion of reinforcement enhances the material’s ability to withstand tensile and shear forces, making it suitable for load-bearing applications.
Lightweight: RAAC retains the lightweight properties of AAC, reducing the overall weight of the structure, which can be advantageous in construction.
Thermal Insulation: RAAC maintains the excellent thermal insulation properties of AAC, contributing to energy efficiency in buildings.
Fire Resistance: AAC, including RAAC, is known for its fire-resistant properties.
Sound Insulation: RAAC can offer good sound insulation capabilities.

Reinforced AAC is commonly used in structural applications where both strength and insulation properties are required. It can be used in residential, commercial, and industrial construction for walls, floors, and roofs. However, it’s important to follow proper design and construction practices to ensure the structural integrity of RAAC buildings. Engineers and architects typically design RAAC structures to meet local building codes and standards, taking into account the specific requirements of the project and the region’s climate and environmental conditions.

While reinforced autoclaved aerated concrete (AAC) has many benefits, it also comes with certain potential risks and considerations:

Lack of Awareness: One of the primary risks associated with AAC is a lack of awareness or expertise among builders and contractors. Improper installation and construction techniques can lead to structural issues or reduced performance.
Reinforcement Corrosion: If not adequately protected, steel reinforcement within AAC can corrode over time, especially in environments with high humidity or exposure to salts. This can weaken the structure and compromise its durability.
Moisture Management: AAC is susceptible to moisture infiltration if not properly sealed or protected. Moisture can lead to mold growth, degradation of the AAC material, and reduced insulation properties.
Inadequate Design: In some cases, the design of reinforced AAC structures may not account for specific structural loads or environmental conditions, leading to potential weaknesses or safety hazards.
Fire Resistance: While AAC is generally fire-resistant, the presence of steel reinforcement can affect its fire resistance properties. If not designed and installed correctly, the reinforcement may become a heat bridge, reducing the overall fire resistance of the structure.

Why is it is the news?

Last week the Department of Education issued an alert to 156 schools, nurseries and colleges stating that the material is now life expired and could collapse with little to no notice. This left said schools scrambling to close and organise alternate arrangements the weekend before they go back. The Department also stated that they not fund emergency measures needed to keep teaching going, placing extra pressure on stretched school budgets. The Cabinet Office also confirmed that 34 other public buildings had also been found to feature RAAC. Investigations are continuing but so far these include 24 hospitals sites with RAAC plank construction in whole or a significant part of their estate. Seven of these need a full replacement and will be rebuilt before 2030.

The Government has been aware of public sector buildings that contain RAAC since 1994 and have been monitoring their condition since 2018. They say that they continually assess new information and research about RAAC to ensure the safety of schools and pupils. In 2022, the Department for Education sent a questionnaire to all responsible bodies, asking them to provide information to help understand the use of RAAC across the school estate and make sure the correct support is in place. Recent cases have now changed that assessment of the risk that RAAC poses to building safety. They are therefore taking immediate steps to ensure the safety of staff and pupils in line with this.

By implementing proactive fire safety measures, you can minimise the risk of fires and protect your business, employees, and customers during a heatwave.

Worlds First Bi-Valiant Heat Pump Ready Radiator

July 17, 2023/0 Comments/in Commercial, News /by joannevickers

ThermAssured is the worlds first bi-vailant ‘dual fuel’ radiant panel heater that combines a wet and electric heating technology into a single emitter.

The UK lags behind the rest of Europe in the installation of heat pumps; especially on retro fit projects. This is mainly because the UK has the oldest housing stock in Europe (>30% built before 1944) and that there is always a concern that older proerties cannot be insulated well enough to be warmed properly by a heat pump.

As a result, heat pump installs are stagnating, and there is a growing number of press articles featuring disatisfied customers who are cold during the worst days of Winter.

ThermAssured provides for an additional heating element in the form of a fire-safe cable that can be activated when, and only when the room fails to reach the target tempertaure in a pre-detremined time scale.

This means that for 95% of the heating season, the heat pump does the ‘heavy lifting’ warming the house using renewable energy as intended. However, after a pre-deterimned time (usually 30 minutes for care homes and assisted living, and 60 minutes in regular residential) if the room has still not reached the target temperature, the back up electric fire safe element kicks in to ‘boost’ the temperature.

Once achieved, both systems can be switched off until the room calls for heat, in which case the process starts all over again.

This means that the eletcric heating is never on when the room is being heated correctly, but is there in the event of a bitter cold snap providing occupants with peace of mind that they wont be cold.

The electrical back up heating can be installed in the most important rooms only (such as main living room and the main bedroom) and not in any others if required.

The heatingt element is also available as an ‘upgrade option’ should the ThermAssured system be installed as a ‘wet’ system only to begin with.

It is therefore now possible for developers and housing providers to have more confidence using renewables, by installing a single heating emitter that can operate on a heat pump, with solar PV back up or mains electric providing an insurance against complaints of underheating.

Manufactured in the UK, THermAssured is launched at Construction Week 2023.

Commercial Fire Safety

April 3, 2023/0 Comments/in Fire Protection, News /by joannevickers

Fire safety is a significant concern in the construction industry. Construction sites can be hazardous due to the presence of flammable materials, temporary electrical installations, and open flames from welding and cutting equipment. In this blog post, we will explore some essential fire safety measures that construction companies should implement to protect workers and prevent fires.

Fire Risk Assessment:

Before starting any construction work, a fire risk assessment should be conducted to identify potential fire hazards and risks. The assessment should take into account the materials used, the location of the site, and the activities performed on-site.

Fire Prevention Measures:

Fire prevention measures should be implemented to reduce the risk of fires starting. These measures include ensuring that combustible materials are stored in a safe location and away from heat sources, keeping temporary electrical installations in good condition, and prohibiting smoking on the site.

Fire Safety Training:

All workers on the construction site should receive fire safety training to ensure that they know how to prevent fires and respond to emergencies. Training should include information on the use of fire extinguishers, emergency evacuation procedures, and the location of fire alarms.

Fire Detection and Alarm Systems:

Fire detection and alarm systems should be installed on the construction site to detect fires and alert workers to evacuate. The system should be tested regularly to ensure that it is working correctly.

Fire Suppression Systems:

Fire suppression systems, such as sprinklers, should be installed on the construction site to suppress fires before they spread. These systems should be installed in areas where flammable materials are stored, and where there is a high risk of fire.

Safe Storage of Flammable Materials:

Flammable materials, such as gasoline, should be stored in a safe location and away from heat sources. They should be stored in approved containers, and workers should be trained on how to handle them safely.

Fire Safety Signage:

Fire safety signage should be posted throughout the construction site to indicate the location of fire exits, fire extinguishers, and other safety equipment. The signage should be visible and easy to understand.

In conclusion, fire safety is a critical concern in the construction industry. Implementing these fire safety measures can help prevent fires from starting and ensure that workers are protected in case of an emergency. It’s essential to conduct regular fire risk assessments, provide fire safety training, and install fire detection and suppression systems to ensure that the construction site is safe and secure.

Fire safety for Buildings

March 1, 2023/0 Comments/in Fire Protection, News /by joannevickers

Broadsword predominately deal in fire safety for buildings at the construction stage, but fire safety is also a critical concern for building owners and managers. Fires can cause property damage, personal injury, and even death. It’s essential to take preventative measures and prepare for potential fires. The following measures should be implemented in all buildings where possible.

Fire Alarms:
Fire alarms are one of the most crucial components of any fire safety plan. They can detect a fire’s presence and alert people in the building to evacuate immediately. It’s essential to install fire alarms in every room, hallway, and other areas of the building where people might be present. Regular testing and maintenance of the fire alarms should also be conducted to ensure they are functioning correctly.

Fire Extinguishers:
Fire extinguishers are critical to have in case of a small fire. They can quickly extinguish the flames before they spread and become uncontrollable. Make sure that there are enough fire extinguishers located throughout the building and that they are regularly inspected and maintained.

Smoke Detectors:
Smoke detectors are essential in any building as they can detect the presence of smoke and alert people to a potential fire. They should be installed in every room of the building and be checked regularly to ensure they are working correctly.

Fire Drills:
Fire drills are critical to prepare for a potential fire. They should be conducted regularly, and everyone in the building should participate. During the drill, people should practice evacuating the building quickly and safely.

Fire Safety Plan:
A fire safety plan is an essential document that outlines the building’s fire safety procedures, including emergency evacuation routes, designated meeting points, and the location of fire extinguishers and alarms. The plan should be easily accessible to all building occupants.

Building Maintenance:
Regular building maintenance is crucial to prevent fires from starting. It includes inspecting and maintaining electrical equipment, removing clutter and combustible materials, and ensuring that fire doors and emergency exits are functioning correctly.

Fire safety is a critical concern for building owners and managers. Implementing these fire safety measures can help prevent fires from starting and ensure that everyone in the building is prepared in case of a fire. It’s essential to have a comprehensive fire safety plan and to conduct regular fire drills to ensure that everyone in the building knows what to do in case of an emergency.

Action needs to be taken on EU carbon emissions

February 13, 2023/0 Comments/in Home Page news feed, News /by joannevickers

EU Building regulations state that all new buildings constructed within the EU must be zero–emission buildings by 2030 and new ‘public’ buildings must be zero–emission buildings by 2027.

WorldGBC has convened a coalition of 35 built environment stakeholder groups, representing over 5,000 organisations from across the building value chain, to call for high level ambition as Parliamentary negotiations on the Energy Performance of Building Directive (EPBD) enter their final stage. With the vote approaching, the coalition is calling on politicians to seize a once-in-a-generation opportunity to eliminate carbon emissions from Europe’s building stock.

This past week WorldGBC has written an open letter to MEPs calling on them to:

Accelerate building renovation and address energy use and efficiency via the introduction of Minimum Energy Performance Standards and harmonisation of Energy Performance Certificates
Address total lifecycle emissions of buildings, including both operational and embodied emissions by supporting provisions regarding Whole Life Carbon reporting, targets, and thresholds

An ambitious EPBD revision will make EU building compatible with EU climate targets, take 35 million citizens out of energy poverty1 and unlock the economic benefits of creating up to 3.3 million green jobs in the EU every year2 while boosting local communities.

In Europe, buildings account for around 40% of energy consumption and 36% of CO2 emissions. Embodied carbon, which refers to emissions from the construction, renovation, deconstruction or demolition and the wider supply chain of a building, contributes typically between 10-20% of the EU building carbon footprint. This means that before a building is even in use, it has already contributed significant carbon emissions and depleted the EU’s ‘carbon budget’.

This letter comes amid growing political and industry support for policy that tackles the Whole Life Carbon impact of buildings.

Will England follow Scotlands lead in green building?

January 24, 2023/0 Comments/in Home Page news feed, News /by joannevickers

All newly built homes in Scotland will need to conform to an innovative green building standard championed by a Labour MSP, under plans announced by the Scottish Government.

Labour’s Alex Rowley proposed the Domestic Building Environmental Standards (Scotland) Bill at the end of 2022 to introduce the Passivhaus standards for all newly built homes in Scotland.

The Passivhaus standards create ultra-low energy homes which aim to minimise the need to heat and cool buildings.

In a letter to Mr Rowley, Minister for Zero Carbon Buildings, Active Travel and Tenants’ Rights, Patrick Harvie confirmed that the Scottish Government would implement the standards within two years through secondary legislation – without the long process of a member’s Bill passed through Holyrood.

Homes built to Passivhaus level meet high standards of airtightness, insulation and energy efficiency, however the Scottish government has confirmed it is introducing its own ‘Passivhaus equivalent’ rather than using existing Passivhaus certification.

This Scottish equivalent will introduce minimum environmental design standards for new build homes to ensure they have high energy efficiency and thermal performance.

The Scottish government says it will implement the new standards within two years through secondary legislation. Development work will commence early in 2023 before the amendments are bought into regulations by December 2024.

A Passivhaus Trust spokesperson added: “It is fantastic to hear the Scottish government has committed to bringing forward a bill requiring higher energy-efficiency standards in domestic buildings, which also recognises the need to assure occupants that the design and construction of these buildings will deliver the actual performance sought in practice.

“Statements including ‘a Scottish equivalent to the Passivhaus standard’ and ‘explicit support for Passivhaus and equivalent standards’ fill us with hope. Now we must ensure that the bill is well developed and implemented to deliver the greatest impact on the actual performance of new homes in Scotland.”

Can a building be net zero carbon?

December 12, 2022/0 Comments/in Home Page news feed, News /by joannevickers

Following on from our post last month about COP27, and the growing importance of sustainability in the construction industry, zero carbon is also something that is increasingly in the news.

A panel has been put together to determine exactly what constitutes a net zero carbon building and is now calling for evidence.

The NZCBS is the UK’s first Net Zero Carbon Buildings Standard and are championing the initiative.

We are calling on UK built environment industry practitioners to share embodied carbon and in-use operational energy performance data for their buildings.

To develop the Standard, benchmarks will be agreed for the operational energy usage and embodied carbon performance levels today, and limits and targets will be set out for future years based on the industry’s required decarbonisation trajectory. To do this, the project is seeking case study data from the real estate and built environment industry.

The deadline for submission is the 16th December.

The Standard will set out metrics by which net zero carbon performance is evaluated, as well as performance targets, or limits, that need to be met. These are likely to include energy use, upfront embodied carbon, and lifecycle embodied carbon, with other metrics – such as space heating/cooling demand and peak load – also to be considered. It will also cover the approach to carbon accounting, procuring renewable energy, and the treatment of residual emissions, including carbon ‘offsetting’. However, the scope and output of the Standard may evolve throughout the development process.

It is expected that claims will be required to be validated based on in-use measured data and interim verification of an asset at design stage or once the asset is built but not yet operating may also be considered.

The output will be for developers, contractors, asset owners and managers, occupiers, investors, financiers and funders, consultants, building industry professionals, building managers and product/material manufacturers, suppliers, and distributors. It is for anyone who wants to either fund, procure, design, or specify a Net Zero Carbon Building and anyone wanting to demonstrate that their building is ‘Net Zero’-aligned with an industry-agreed Standard.

Performance targets will align with science-based trajectories needed to achieve net zero by 2050 and a 78% reduction by 2035 in the UK, i.e. what is known to be required to stand a reasonable chance of mitigating global warming to 1.5°C. It will also align with the energy demand reductions projected to be required to enable a net zero carbon energy supply sector.

The approach will be applicable to both existing and new buildings (e.g. Homes, Offices, Education, Industry, Retail, Hotels, Healthcare etc.). To start, the focus will be on the most common building typologies, especially those for which industry stakeholders have already robust performance data available to inform the setting of performance targets. The Standard will not apply to infrastructure.

The project will hopefully launch in May.

So, what actually is a net carbon building?

A carbon neutral building is one where the design, construction, and operations do not contribute to emissions of greenhouse gases that cause climate change. Reducing harmful greenhouse gas emissions from the building sector will greatly help meet climate goals.

In the short and medium term the national grid will not be fully decarbonised and so buildings will need to make use of carbon offsetting to achieve a net zero carbon balance.
