Here at Classic PVC in Llanelli we've been installing quality uPVC double glazed windows & improving homes throughout South Wales since 1994.

uPVC Windows from Classic PVC

New windows can really enhance the look of your home, both from the inside and out. We offer a wide range of styles to suit both traditional and contemporary properties. Opt for traditional white uPVC frames, or a natural woodgrain effect in golden oak, rosewood or mahogany. Then decide if you'd like Georgian, stained, diamond lead or bevelled glass.

Whatever style you go for, you'll find our windows aren't just pleasing on the eye, they're practical too. Miniumal maintenance means their good looks will last well into the future, giving you total peace of mind.
