Wraptite® THE SELF-ADHERING AIRTIGHT AND VAPOUR PERMEABLE MEMBRANE
WRAPTITE OFFERS A COMPELLING COMBINATION
By combining vapour permeability and airtightness in a unique, self-adhering membrane, Wraptite offers a fast
and effective solution to unplanned air leakage and its detrimental effects on energy performance. With BBA
certification for a comprehensive range of wall and roof constructions and compatibility with multiple substrates,
this high-performance air barrier solution can be employed on projects from domestic scale timber frame to large
steel framed high rise and everything in between.
With an Sd-value of 0.039m, Wraptite’s high vapour permeability means any construction moisture can dry
out rapidly, reducing the likelihood of mould, mildew, and condensation related damage such as timber rot and
distortion or metal corrosion. This ensures the building fabric remains as healthy as the indoor environment.
Vapour permeability also allows flexibility in the placement of the air barrier, meaning it can be moved outwards in
the construction without risking trapping moisture. This minimises the potential for damage from following trades, in
turn allowing design air leakage rates to be reduced with increased confidence pressure test targets will be met
