Airtightness in buildings is crucial for controlling condensation and maintaining both structural integrity and occupant health. By preventing air leakage with well-designed air barriers and vapour control layers, the risk of warm, moist air reaching colder surfaces and condensing is significantly reduced, thereby avoiding issues like mould growth and structural
We help builders across the UK with airtightness testing because getting it right first time saves stress, time and money. When air leaks out of a new build, it drives up heating bills, creates draughts and can lead to failed tests that delay handover. That’s why we plan early, walk
Air tightness testing checks how much air leaks through gaps or cracks in your building that should be sealed. We use special equipment to spot where warm air escapes or cold air sneaks in, which can lead to higher energy bills and discomfort inside. Most new builds in the UK
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
