Air Sealing

With rising concerns over energy efficiency in building construction, preventing air leakage has become a priority. Air leakage leads to the loss of heated or cooled air, forcing HVAC systems to work harder and wasting energy. Air sealing ensures that the building maintains a consistent temperature, reducing the need for excessive heating or cooling. It also helps meet legal requirements, such as those outlined in the Approved Document L1 by the Department for Communities and Local Government, which mandates energy-efficient construction to lower carbon emissions and reduce energy wastage.

Air sealing also improves comfort, reduces energy costs, and enhances the working environment by stabilizing indoor temperatures. In addition, it can improve indoor air quality by reducing drafts and preventing unwanted pollutants from entering the building.

At Ignis Praesidium, we work closely with clients to identify the most effective air sealing solutions for their unique building needs. Our team utilizes advanced techniques and high-quality materials to select and install the most suitable air sealing systems, ensuring the best possible results. Whether it’s sealing small cracks around windows, larger gaps in the attic, or complex service penetrations, we tailor our services to meet the specific requirements of each structure.

Our services contribute significantly to reducing energy bills by preventing heat loss in the winter and keeping cool air inside during the summer. This helps maintain a consistent and comfortable indoor temperature year-round while lowering energy consumption. Additionally, by minimizing energy waste, our air sealing solutions support broader environmental sustainability efforts, reducing the carbon footprint of the building and helping clients meet green building standards.

To address potential air leakage, an air leakage examination is typically conducted to identify areas where air could escape. Common problem areas include:

• Service risers
• Gaps between external cladding and internal walls
• Window and door frames
• Other penetrations through external walls

Once these areas are identified, a rigid foam insulation board is friction-fitted into the open voids between solid structures, followed by sealing with an airtight silicone mastic. In some cases, a fire-rated system can also be applied to provide additional protection against fire, smoke, and air leakage, ensuring both safety and efficiency.

Here are some benefits of employing our air sealing systems:

• Energy Efficiency: Reduces heat loss and energy wastage, leading to lower energy bills and carbon emissions.
• Airtight Seal: Effectively blocks air leakage, maintaining the building’s internal temperature.
• Durability: The system is unaffected by humidity, providing long-lasting results without the need for ongoing maintenance.
• Easy Installation: The air sealing process is straightforward, minimizing disruption during installation.
• Fire Safety (Optional): Fire-rated systems can be implemented where needed to ensure comprehensive fire, smoke, and air-tightness protection.
