Double Glazing Sheffield In South Yorkshire Looks Intently Into The Question Of If Triple Glazing Is Actually More Okay Compared To The Double. For many years the UK window market has concluded that the idea of bigger means better. 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

The new question being asked is, are triple glazed windows better than double? Is three really better than two? ( To understand the situation people will be required also to understand the simple answer as no answer for this question is in sight. . 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 recent industry recognised excellent double glazed unit consist of one 4mm sheet of “low E” (Low emissivity) coated glass, one sheet of 4mm unembellished toughened glass and 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. The ideal thickness is 44mm (4mm, 16mm, 4mm, 16mm, 4mm), which gives us a u-value of 0.9 W/ m2K. We could enhance this more by bringing in a second “Low E” pane in which the unit u-value turns to 0.6 W / kilojalores per metre squared.

Looking at this in terms of the heat loss prevention due to glazing, going from 1.1 W/ m2K to a possible 0.6 W / m2K seems like something worth forking out for

The Window Energy Rating Scheme which has been widely accepted as the industry standard to judge thermal performance and also been subscribed into Building Regulations calculates solar gain along with heat loss. . What this mean is, the triple glazing windows increased head loss is canceled out by the reduced amount of solar light that can enter.

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

Triple glazing purveyors have to take another aspect into consideration. Thermal tension can cause a gap in the units. The centre pane of a triple glazed unit does not have any air movement around it because of the encapsulation the temperatures can reach higher than can be expected for double glazing. . The way around this problem is to use a reinforced pane of glass in the middle, but this would again increase the cost of the window.
So, we’ve answered the question to is it possible to increase thermal effectiveness by using a triple glazed window. But what about the price? It’s something that needs to be taken into consideration as energy costs rise by double digit percentages every year.
