Superb glazing Company

We previously had patio doors from Humberside glazing, this time we have had a new back door and several windows, and both times they have done an extremely good job. The fitters were pleasant and helpful and Darren who does the measuring, is also pleasant and helfpul and very accurate with his measuring. Would not hesitate to remommend this company. Simon, Owner has a really good team.

Only a small job, but it was treated with the same attention and detail as a larger order. Work was carried out by Andy, in a cheerful and professional manner.
Would certainly use Humberside Glazing again should the occasion arise.

FAQs

Simply put, they are the actual glass parts of your windows. Instead of just a single pane of glass, a sealed unit uses two panes trapped together with a layer of insulating gas in the middle. This clever design acts like a thermal blanket for your home, trapping heat inside and keeping chilly draughts out.

We can also include advanced features such as Swisspacer warm edge spacer bars, Low Iron Glass, and Argon gas filling to improve thermal performance and create high energy sealed units.

Yes. Modern sealed units can help reduce the amount of external noise entering your property, creating a quieter and more peaceful indoor environment.

Absolutely. Older glazing can allow heat to escape more easily. Upgrading to modern double glazed sealed units can improve insulation and help maintain a consistent indoor temperature.

Toughened laminated glass offers added safety and security compared to standard toughened or annealed glass because it remains held together even if broken, helping to prevent dangerous falling shards.

Each sealed unit is manufactured with Planitherm coated technology. This is a transparent coating to reflect heat back into your home while letting sunlight pass through, creating a safer, warmer, and energy efficient living space.

Yes. Our sealed units improve thermal performance around the glass surface, helping to reduce condensation build up for a comfortable living environment.

By keeping a consistent temperature, high performance sealed units can also help reduce cold spots near windows and improve overall energy efficiency throughout the home. This creates a living space that feels warmer during winter and more comfortable all year round.
