For example, sometimes cavity-wall insulation actually in creases heat loss because a poor installation supplies ‘cold bridges’. In fact, that is very common, and poor-quality workmanship undermines a good deal of the expected gains from increases in building standards. Perhaps you might also have pointed out that a good U Value for the window unit is useless if the thing is poorly fitted and leaks draughts around the edges. The point about solid wall efficiency is a good one, but a bit misleading – more effective is to add internal or external insulation, and if you self-fit internal insulation (not difficult) it will pay for itself in a few years. Would it not have been better to point this out? A few percent is less than the effect of a little dust on the window – and there is always dust – or a bit of curtain blocking one corner. Meanwhile, the original point about reducing light intensity is mostly erroneous it will be a few percent at most, since the internal sheet in triple glazing will remain clean. That leaves the psychological effects of brighter rooms compared with enclosed space, and with that there can be little argument enclosure increases depression.
Triple glazed windows r value keygen#
If you would like us to find you a local installer, just fill in the form below and we will be in touch shortly!ĭo you not think that if the light transmission is reduced and then the window size increased to compensate, you are back where you started with regard to the ‘health effects’? In fact glass blocks various wavelengths and partially absorbs others, so no amount of window is going to allow you to make Vitamin D from sunlight and you will have to go into the garden. Need your windows replaced? We have scoured the country for the best tradespeople, so that we can make sure we only recommend those we really trust.
This is a removable pane which acts the same as double glazing but at a fraction of the price. The main alternative to triple glazing is to add secondary glazing like Ecoease to your existing windows. Triple glazing is an excellent solution to this problem, as it reduces the difference in U-value between the windows and the rest of the building. This problem is exacerbated by modern insulation – as better and thicker wall insulation means windows become much colder compared to the rest of the house. Triple glazing offers a significant reduction in noise pollution – so it is ideal for those living in noisy areas.ĭouble glazing can create cold patches in the house, due to the higher u value of windows compared to walls and doors. Triple glazing can help reduce condensation on your windows. So triple glazing doesn’t really pay for itself, but are there other reasons for getting it above double glazing? Here I will go through a couple of other reasons why you should consider triple glazing. Adding thick curtains, and keeping them closed at night will help reduce your bills also. If you are going to have triple glazing, you will need well insulated frames, as this is one of the major heat loss areas in a window. If you are getting your windows done anyway, or you are building a new home, triple glazing is not a bad idea, but if you already have double glazing, triple glazing might not be right for you.Īre there other things you can do to reduce your U-value?
Why? Well the cost of triple glazing is a fair bit higher than double, whilst the improved U-value is not very large. Changing from single glazing to triple glazing, in terms of energy efficiency payback, is very similar to double glazing payback. As we have mentioned elsewhere, on a purely efficiency basis, double-glazing does not pay for itself and triple glazing is no exception. Lots of new homes are now being built with triple glazing and it is generally acknowledged as being better, but compared to top double glazing, the payback period is very similar. This is a considerable improvement on even modern double glazing. In Scandinavia, triple glazing is now pretty much standard, with modern triple glazing taking the U-value of the windows down to around 0.8. Can you reseal double glazing?
