Feeling the cold? It’s the time of year, of course. But one factor that could be causing it is a lack of airtightness.

It’s the cause of lost heat, more expensive utility bills and potential risks to your buildings over time. Without proper airtightness, your building will suffer and with holes being left unfilled, it’s more likely to get worse than it is better.

Here’s a brief explainer on airtightness in buildings.

The problem

Airtightness has only one aim – to completely seal off unintended gaps or cracks on the exterior of a building. As a result, occupants can expect an internal atmosphere that is healthy, comfortable and energy-efficient.

However, when using poor quality materials, or not complying with the Government’s Document L, buildings are often not airtight. What’s the result? Increased heating costs, greater pollution through lost energy and a non-compliant building.

The solution

Fixing a lack of airtightness can be a complex process, depending on whether your building is new or old.

To measure airtightness, air will be blown into the building and the air which leaves the building will then be measured. If you haven’t sealed it correctly, more air will come out and the building will not be airtight, and therefore not compliant with Document L.

HS Butyl tapes seal joints between metal-clad buildings to provide more airtightness. But you need to ensure you’re using high-quality, trusted and tested butyl that stands the test of time.

Helping new buildings stay efficient and compliant, HS Butyl tape is found on buildings across the UK and beyond.
