Fibreglass Doors

KV’s fiberglass doors are available in a warm wood finish or classic white and available in a large range of designs and styles. They are as elegant as they are sturdy, handling the harsh Canadian climate without cracking, warping, or rusting.

Fibreglass doors are offered in a woodgrain or smooth texture. The woodgrain paired with a stain or paint can give you a wood door look. See the tab below for more information on fibreglass doors.

Patio Doors

Sliding glass patio doors offer a perfect combination of beauty, security and low-maintenance. Unlike hinged doors, they glide open and close with ease and take up less space, making them an ideal option when space is tight – and foot traffic is heavy.

We offer patio doors by KV Custom and North Star. See the links below for more information.
