DURABILITY
Because sash windows slide along the weatherpile ,they are subjected to large
amounts of directional force. Polypropylene is a highly resilient material well
suited to cope under these aggressive conditions.
WATER REPELLENT
Weatherpile is woven from yarn which has been impregnated with silicone, thus
offering an additional barrier against water absorption.
WEATHER RESISTANT
Not only is weatherpile an excellent draught-proofing product, but it is also
highly resilient to abrasion, ozone & biological attack. The yarn is UV stabilised
to minimise the effects of ultra violet light
