Product Details

Airtightness is absolutely essential in order to maximise the effectiveness of thermal insulation. Hence the requirement for airtightness in low-energy buildings.

Ideally, 1.5-3.0 air changes per hour should be aimed for, at a pressure difference of 50 Pa.

However, implementation of airtightness in practice is rare. On the one hand, there is a lack of awareness about the function and significance of an airtight seal amongst builders and architects. On the other hand, there are almost no products available which actually meet the requirements for perfect airtightness.

Moisture ingress with airtight vapor/vapour retarder with a sd-value (mvtr, permeance) of 30m (150MNs/g, 0.11 US perms): 0.5g water/m2 x 24h (6.4grain water/square yard x 24h) Moisture ingress with 1mm gap in vapour retarder: 800g water/m2 x 24h (10,266grain water/square yard x 24h). Performance down by factor 1,600
