Double Glazing Suffolk In Suffolk Looks Intently Into The Question Of If Triple Glazing Is Actually More Okay Compared To The Double. Bigger has always been considered as better by numerous people within the United Kingdom with particular mention being made about the domestic window market. . The market for double glazing has changed consistently starting from an overall thickness of 20MM to 24MM and ultimately settling down on 28MM despite having the information that 24MM is the best option available thermally with air or argon gas cavities. .

Thanks to the idea that bigger is better, the borders go from 60mm to 70mm without an actual technical advance

A more recent question to the window market is – is 3 glazings better than 2? Or is triple better than double? (https://doubleglazing-suffolk.uk). The straightforward reply is there is no straightforward reply. The Difficult Aspect Of It, As Always, Is In The Detail. To be able to properly answer this question, we need to take into account the personal aspects of a proposed Insulated Glass Unit (IGU).

The standard double glazing glass unit is composed of one 4mm panel of low emissivity glass, one panel of annealed glass and a 20mm gap of argon gas. (4mm, 20mm, 4mm)

This combination will provide a centre pane U-value of 1.1 W/M square K. . If we add a centre pane of plain glass but maintain the 28 mm thickness of the unit (i.e 4 -8 – 4- 8 – 4), we get a u-value of 1.2 W / kilojalores per metre squared which is a worse performance than double glazed. But to have a better functioning of the unit, we must have a larger thickness of the triple glazed unit. To get to a u-value of 0.9 W / kilojalores per metre squared the thickness required is 44mm (4-16-4-16-4). This could be improved further still, by adding another low emissivity panel, the u-value would drop to 0.6 W/ m2K.

On the surface, going from 1.1 W / kilojalores per metre squared to 0.6 W / kilojalores per metre squared in terms of heat loss seems like something worth paying for

A widely accepted industry standard for measuring thermal performance and a part of Building Regulations, The Window Energy Rating Scheme judges heat loss as well as solar gain. The heat caused by the sunlight tear downs apart the number of the triple glazed units.

Using Low Iron glass to get a high solar gain is one solution, but because if is more translucent than traditional glass, it can be significantly more expensive

There is another factor that suppliers of triple glazing must carefully think about. This problem relates to cracking in the panels of the glass due to the increased thermal stress. The centre pain of a triple glazed window is encapsulated and therefore has no air around it, so it can reach much higher temperatures than double glazed windows. A solution to this is to use tougher glass in the centre, but this would again raise the cost.
So shifting the triple glazing is a way of having a better thermal execution of IGU. But this sparks a new questions – at what price? It’s something that needs to be taken into consideration as energy costs rise by double digit percentages every year.
