Radon/DPM Double Sided Butyl Jointing Tape 50mm x 10m

Product Details

Looking for a practical and cost-effective way to damp proof your loft conversion or basement refit using butyl tape? Try this double-sided one from Damplas. 

The tape uses a high-quality adhesive that bonds firmly to damp-proof materials or membranes. This means you can count on it to stick in areas with high amounts of moisture in the air, such as bathrooms, attics or basements.

There's also no chance of moisture seeping through your walls or floor and causing damage, as the butyl material is totally damp proof. It's supplied on a roll, so it's easy to use too. All you need to do is overlap your membrane material by a minimum of 150 mm and then apply the tape in between the two layers. Once you're done, apply a length of Damplas single-sided jointing tape to seal up the overlap.
