Product description

Peppard Building Supplies has Rockwool's Flexi insulation in stock.


It is a multi–use, dual–purpose thermal and acoustic insulation product with a flexible edge along one side. The flexible edge ensures a snug fit between the product and its supporting framework for optimum insulation. It also has an A1 fire classification.


The open, porous structure of this stone mineral wool makes it highly efficient in protecting against noise pollution. Made from a renewable and plentiful natural resource and being 97% recyclable, Rockwall is also an environmentally friendly choice.


This innovative range is made from ‘stone wool’, using naturally occurring, volcanic diabase rock. This makes it durable and resistant to shrinking, moving or crumbling.


As the rock is a naturally non–combustible material, it offers added peace of mind in the event of a fire. It is also water resistant so (once dry) will perform as before after a leak or flood.
