Rated 5 out of 5 by from What a great find! Building a workshop with corrugated roof and I wanted to lay a barrier down. I could tell the quality of the A1 Protect. water resistant, strong and easy to lay. Finished laying at 9 pm, ready to do corrugated steel in morning. Heavy rain storms during night and it withstood the test. Definitely buy again.

Rated 5 out of 5 by from just what i needed i needed a liner for my metal shed,this seemed to be the best option as i was trying to get rid of the dreadful condensation problem i is easy to cut,does not rip and by using builders double backed tape (also from screwfix) it adhered easily to the metal.this has transformed my shed from a damp metal box into a dry workshop,an excellent product.
