Question:
My garage roof is metal box profile sheets. Can this product be applied directly to the underside of the roof sheet? In this way, will this product contain condensation? How and when will the condensation be released?
Answer:
Condensation forms where the cold and hot air meet, so really to reduce this you need to be insulating the roof not just applying a membrane.
