Endurance Doors now offers a 3mm bowing guarantee for its composite doors.
The performance of some solid core composite doors has come under great scrutiny during the year, and product liabilities have become a major issue for some businesses, the company said.
Endurance Doors said its Moisture Barrier System, CoolSkin PVCU door skins, and the fact that glazing apertures are wet sealed, meant product remedials have disappeared.
Stephen Nadin, managing director of Endurance Doors, said: “Our price freeze for 2020 went down very well with our installer partners and now our 3mm bowing guarantee will give them even more confidence and trust in us, with the promise of the long-term, trouble-free performance of an Endurance Door.
“Product liabilities have been an issue for the composite door sector at times and so that’s why we’ve invested in better materials and production processes since 2002.
“This is to make our doors a standout performer, backed with exceptional customer service and a powerful marketing programme.”
