I'm so impressed with the service Art On Glass have provided me - couldn't be happier. The uPVC Liniar windows they installed throughout my home look beautiful, and I can really feel the benefits of their thermal efficiency properties.

Art on Glass Testimonials
We went to Art On Glass for a bespoke glass table top for our dinning room table. They were recommended to us by a friend who had used them and we were highly impressed with their service and product knowledge. So much more than just a double glazing company.

Art on Glass Testimonials
My husband and I were looking for something a little bit different from the usual uPVC product. As Art On Glass also install beautiful aluminium windows and doors they were the perfect choice for us. We are so pleased with our new aluminium bi-fold doors that are very strong and weather resistant.

Hand Finished Process

Each of Liniar’s uPVC frames are hand finished by skilled craftsmen to offer the finest quality finish, unrivaled by other companies. There are 4 steps to the hand-finishing process:

  1. All corners are checked for their appearance and completed by hand to ensure precision  and finish.
  2. The outside edges are levelled at the corners to maintain a beautifully square silhouette.
  3. To keep every window identical, each corner groove is checked for depth and manually corrected.
  4. All apertures are inspected for weld build-up and any protrusion is removed for a tight weather seal.

Perfect Liniar Profile

We are fully accredited suppliers and installers of Liniar’s exceptional uPVC profile. What makes it so special? A Liniar window profile contains 6 size-optimised multi-chambers to lock in pockets of warm air.

Flipper gaskets are in place to reduce cold spots, water ingress and noise pollution. Superbly weather proof, structurally sound and designed to maximise natural drainage, you can’t beat a uPVC Liniar profile.

With built in thermal dams designed to Passivhaus recommendations, the thermal dam is in place to reduce heat transfer. The perfect solution to saving you money on your heating bills as warm air is contained inside your property.

Why our windows are just better than the rest

As part of the Double Glazing Network, we specialise in the supply and installation of quality Liniar windows, doors and conservatories. Our windows are hand finished to the highest standards by our team of skilled craftsmen to ensure only the very best finish is provided. Made to measure to suit your requirements, we can guarantee a 10 year manufacturer’s guarantee against cracking, warping or discolouration, so you’re always protected.

Environmentally Friendly

Each of our Liniar uPVC window systems are highly energy efficient and environmentally friendly. With British manufacturing you know you are receiving a trustworthy, home-made product.

Liniar profiles are manufactured using 100% lead free materials. Contributing to a green environment, our profiles never use steel reinforcements as they are internally structured to provide exceptional stiffness.

Our multi-chambered technology is far more thermally efficient than any previous uPVC design. With the highest WER available your home will remain warm and cosy throughout the winter months.
