The protective function of nail sealing
What use is the best roof support, when water can penetrate the screw or nail holes? Ampacoll® ND nail sealing guarantees a waterproof roof support. Twisted counter battens, shrinking wood, extreme alternating cycles of wet and dry, low contact pressure, poor adhesion of the nail in the rafters, mechanical loading from scaffolding or tile trestles, permanent snow coverings – these are all potential sources of damage!

Processing instructions

Make a chalk mark with a piece of string for each counter batten and glue the Ampacoll® ND / ND.Band nail seal directly on the roof membrane to form a diamond shape. This ensures the water flows away much better! Then install the counter battens.

Ampack recommends
Counter battens are subject to extreme alternating cycles of wet and dry. For a better seal, screwing the battens on is preferable to nailing.
