TYVEK an innovative approach to airtightness

TYVEK are one of the main leaders in airtightness in today’s construction. We at Eco Building Systems are now stocking a range of TYVEK airtight materials including the airguard reflective vapour control layer, the metallised tapes and also the TYVEK Supro roofing felt.

The TYVEK airguard reflective is 100% airtight but also acts as a vapour control layer, it can be used in traditional builds as well as timber frame contruction. This product has a reflective layer with low emissivity and when combined with a non ventilated airspace, it can boost the thermal insulation of a building significantly. It measures 1.5 x 50m and can be used in walls, roofs (see picture) and below ceiling levels. The two main advantages of using this product are:

– a reduction of heat loss by convection or radiation
– moisture management by preventing condensation on the inside of the building by both diffusion and convection.

This vapour control layer works best in combination with the tyvek metallised tape.
