Q-lon vs EPDM for seals in UPVC windows Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

Any views on the relative merits of Q-lon and EPDM for use as gasket and seals in UPVC window systems. I am looking at Duraflex frames that are using Q-lon for both but it looks like it could be prone to damage and wear.
