Vinyl Windows & Doors

One of the main things that sets Clera Windows & Doors apart from our peers is our choices.

Vinyl is a tremendous material for making furniture and a lot of other articles: it’s cheap, easily available, and lasts longer than you could possibly imagine. It doesn’t weigh much, which adds brownie points to the prospect of using this material for our replacement windows and doors in Guelph.

Using vinyl ensures that the weight is under control, as well as guaranteeing that there is enough portability in the furniture for a quick replacement.
