Frequently asked questions
Do I need to tape the joints?
Do I need to tape the joints?
Do I need to tape the joints?
Yes, you should always tape the laps, usually with the Ampacoll XT tape. This ensures the wind-tightness of the exterior of the building and reduces heat loss from wind penetration.
How long can I leave it exposed?
This membrane is very UV stable and can withstand up to 3 months of weathering without deterioration. Beyond this the sun can begin to degrade the strength and weather resistance of the membrane.
