Air Tightness

SAP air tightness certification checks how well a home keeps warm air in and stops draughts getting through gaps and cracks. We test this by using a fan to push or pull air through the building and measure how much escapes. If too much leaks out, your house will be

We test how much air leaks in or out of a building when it’s meant to be sealed up tight. This matters because if too much air escapes, your heating or cooling has to work harder, meaning higher bills and more stress down the line. At Ratio Seven, we help

We get asked all the time what air pressure testing is and why it’s needed, so here’s the easy answer: it checks how much air leaks from your building. Too many gaps make your home cold and expensive to heat, and it can even stop you from passing building regulations.

At Ratio Seven, we test how airtight your building is by checking for any gaps where warm air might sneak out. It’s all about helping you keep heat inside, cut energy bills, and meet current building rules. We use a special fan to spot leaks and let you know what

Airtightness testing, also known as blower door testing, is pivotal in whole-building life cycle assessments, significantly influencing energy efficiency and operational emissions by minimising air leakage and reducing the need for heating and cooling. This testing is essential for Whole Life Carbon Assessments, as it mitigates operational carbon emissions by

Permeability testing, also known as air tightness testing, plays a vital role in enhancing energy efficiency by identifying and rectifying air leaks in buildings. In Leicester, this process is not only crucial for reducing energy wastage and operational costs but is also mandated under Building Regulations Part L1A, ensuring buildings

We carry out airtightness testing to find where air leaks through gaps or cracks in a building, so those spots can be sealed before they waste heat and money. It’s like shutting a window you didn’t know was open. By spotting the sneaky places where warm air escapes or draughts

Air tightness plays a pivotal role in modular construction, enhancing energy efficiency, comfort, and overall building quality. By minimising air leakage, buildings can achieve significant energy savings, which allows for less intensive insulation materials and contributes to environmental sustainability. Beyond energy efficiency, airtight structures help create healthier indoor environments by
