Airtightness is crucial in self-build processes to minimise the amount of air that leaks from your home. A building with poor airtightness loses a significant amount of heat as warm air escapes, leading to expensive heating bills. Warm, damp air leaking into the fabric of a building also causes condensation, which can weaken building materials.
To avoid this, current Building Regulations specify a minimum airtightness of 10m3/h/m2. Frame Technologies exceed this by achieving airtightness level of 3m3/h/m2. With the need to control air leakage as defined in Approved Document L of the Building Regulations, Frame Technologies supply effective barriers to assist in the reduction of air leakage that include:
- Membranes and/or tapes for sealing joints or apertures around building services.
- Airtightness detailing in critical areas such as intermediate floor to external wall panels.
- Battens to form service zones and reduce the need for penetration through the barriers.
- OSB sheathing on internal faces of external walls that are then taped to provide excellent results.
