A+Rated 0.8 U-Value Triple Glazing. Our brilliant Triple glazed window is incredibly energy efficient and only slightly more expensive than double glazing.

Our new triple glazed windows offer some real advantages over the already super-efficient enviro double glazed windows.

One major advantage being that they are available for only a very small price permium over double glazed windows, one that many people are prepared to pay when they see what triple glazing offers.

Even better insulation agains the cold
Our advanced new triple glazed system has been fully tested (registration number 0375-006AAA) and is rated at 0.8 U-Value, meaning that while many of our competitors offer windows rated at C or B rating, ours easily achieve the highest possible rating for energy efficiency. The A+ rating simply signifies that for energy rating the window is the best of the best.

tripleWith 3 layers of glass separated with gas acting as insulating pockets triple glazing offers better levels of insulation than similar double glazed units.

You’ll also find that our triple glazing and high performance uPVC frame and chamber design cuts down the risk of draughts and condensation even further than traditional double glazing.

Noise reduction, another major strength of triple glazing
Walls are thick and muffle sound well and you will definitely notice a large reduction in outside noise when moving from single glazing to double glazing.

That extra layer of glass really makes a difference. Adding a further layer of glass helps even more, cutting down external noise like traffic sound quite dramatically. Triple glazing is absolutely ideal for people who work shifts and live near busy roads or often hear the sound of children playing outside.

High strength frames mean no sagging under the extra weight of triple glazing
Many companies offering triple glazing simply add the triple glazed glass units to their existing frames. This is a really bad idea. Glass is heavy and over time that extra weight causes sagging in the frame resulting in windows that don’t open or seal properly and after a few years often break completely. It’s this issue that put us off supplying triple glazing until a few years ago.
