Double Glazing Bristol In Bristol Looks Intently Into The Question Of If Triple Glazing Is Actually More Okay Compared To The Double. For years the indigenous window market in the UK has evolved on the proposition that bigger is better. The thickness of double glazed windows has varied over the years, from around 20mm to 24mm, and then settling on 28mm, despite 24mm being the ideal size for thermal capacity.

The misconception that bigger is better also influenced the growth of frame depths, from 60mm to 70mm with no real technical advantage

But, is really triple glazing better than double? 3 works better than 2? (https://bristol-doubleglazing.com). The straightforward reply is there is no straightforward reply. Everything, As Always, Is In The Detail Of The Work. We must have in mind the specs of any recommended IGU (Insulated Glass Unit) to offer a good response to that question.

The present industry standard which is being applied for double glazed units is off one 4 MM pane of low E [low emissivity] coated glass and one pane of 4 MM plain annealed glass along with a 20MM cavity of argon gas [makeup = 4-20-4]

1.1 W / kilojalores per metre squared is the u-value of the center panel offered. If a center pane of plain glass is introduced, but the overall thickness of the unit is retained at 28 MM [4-8-4-8-4] we can arrive at a U value of 1.2 W/M sq. K which will deliver a performance that will be worse than a double glazed unit. 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). Improvements can further be made by introducing a second low E pane where the unit U value changes to 0.6 W/ M Sq. K. .

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

The Window Energy Rating Scheme, generally approved, as the industry level of quality for determining thermal efficiency and written into Building Regulations, measures solar gain as well as heat loss. This implies that the triple glazed unit’s enhanced heat loss qualities are greatly nullified by the reduction of heat produced by the sunshine.

However, in order to increase the solar gain by using low iron glass that is more translucent than the conventional variety can be substantially more expensive

There is another factor, which must also be considered by the purveyors of triple glazing. . Thermal tension can cause a gap in the units. 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. To correct this, use a toughened pane at the middle of the unit, this will unavoidably raise the cost again.
So, is it possible that triple glazing can improve thermal performance of IGU? But this sparks a new questions – at what price? Energy costs are consistently rising by double-digit percentages year after year and it is a calculation, which must receive significant attention.
