Triple glazing provides higher energy performance and acoustic, noise reduction. Sevenday PVCu triple glazed windows and doors also have additional benefits which are detailed below.
Firstly, the glass unit is made up of 3 (triple) layers of 4mm glass, these are seperated by 12mm cavities that are filled with 95% Argon Gas. The Argon Gas is used as it is denser than air and as a result provides a more effective cold barrier between the panes. All this is then surrounded with 2 layers of 'warm edge' spacers which seal the glass togeter. The benefits of the warm edge spacer is that it too provides a cold bridge barrier which ensures the inner pane of glass is warmer than the outside. The overall thickness of the Sevenday triple glazed units are 36mm.
Energy performance - Sevenday triple glazing uses Pilkington glass which ensures you have the very best in glass technology and performance. Triple glazing will provide up to 40% greater thermal efficency than a standard 'A' Rated double glazed unit, and 60% more than a 'C' Rated double glazed unit. Therefore, by investing in PVCu triple glazing for your replacement windows, you could reduce your home energy bills even further.
According to the GGF Energy Saving Calculator double glazed 'A' Rated windows will save you approximately £7,400 in energy bills and 23 tonnes of Carbon over 20 years, with triple glazing being at least 40% more efficient the savings are going to be considerably higher.
Noise reduction - Whether you live near a major road, under a flight path or near some vocal wildlife, noise pollution can be a cause of major disruption. As well as 2 Argon Gas filled spaces sandwiching the extra glass pane, triple glazing features an additional 12mm cavity. The insulation coupled with our high performance warm edge spacer allows Sevenday triple glazed units to dramatically reduce external noise pollution. Furthermore, all Sevenday windows and doors are supplied with our innovative and high performing Q-lon weatherseal, which has a lifetime guarantee. The Q-lon incorporates a foam core wich not only allows for easier operation and closing forces but alos absorbs noise, particularly when compared to ridgid weatherseal gaskets.
Thermal Construction - In addition to the triple glazing glass technology, all Sevenday windows are manufactured using composite reinforcements. These not only provide strength and rigidity to aid security but also improve the thermal performance of the frames, all designed to give you the best performing window system.
