Roofing Felt Information
Roofing Felt Info:
"Traditional Roofing Felt
Traditional Roofing Felt is composed of a fibre
base saturated and then coated with bitumen and surfaced with
either sand or a slate finish. Used in a single, two layer or
three-layer application, these products are ideal for use as
temporary waterproofing or for use on sheds or garden buildings.
Traditional Roofing Felts are not recommended for use on habitable
buildings, such as domestic extensions.
Polyester Based Roofing Felt
General Purpose Roofing Felts are composed of
either polyester or glass fibre bases, saturated and coated with
oxidised bitumen. They offer a higher degree of performance,
strength and stability compared to fibre based felts. Bonded with
cold applied adhesives or hot bonding bitumen, they are
predominantly used in two or three layer systems and are ideal for
use on garages and domestic extensions, although they can also be
used on garden buildings where increased performance is required.
The Polyester 180 Sand also makes an ideal nailed preparation layer
when using torch-on membranes on a timber deck.
Torch-on Roofing Felt
The roofing felts offered in this range provide
for all the basic torch-on needs of the builder's merchant. The
range combines polyester or glass fibre based products, saturated
and coated with APP modified bitumen. They offer comprehensive
options for high performance and economy specifications. Products
within the range can be applied as a single remedial layer, over
bituminous waterproofing, or form a multi-layer built-up system.
Applied by using a gas torch, these products are suitable for use
on garages, domestic extensions and industrial/commercial
Coldseal Self-Adhesive Roofing
Coldseal self-adhesive roofing felts are composed
of polyester bases, saturated and coated with SBS modified bitumen.
The reverse side is treated with a self-adhesive coating and
surfaced with a removable release sheet. Applied as a two-layer
system (underlay and cap sheet), both layers are bonded by the
removal of the release sheet on the back. Coldseal self-adhesive
roofing membranes are high performance products, ideally suited for
use on domestic garages and extensions. The self-adhesive
application, combined with the Quicktrim range of pre-formed edge
details available, make them safer and easier to install, providing
long lasting, cost effective, guaranteed performance".
