DELTA ROOF UNDERLAYS – made using latest DELTA BiCO technology
To be of good quality, a pitched roof needs to fulfil many more functions today compared to a few years ago. Not only should it offer lasting protection from weather and environmental influences, it should also meet the most exacting requirements as regards aesthetics. The objective is, therefore, to perfectly harmonise the visual and functional aspects of a pitched roof. Besides, energy efficiency is becoming an increasingly important issue for builders and owners, an issue that must be addressed when building or refurbishing a roof.
