We go into another year when house extensions of all sorts and sizes remain deservedly popular, in a housing market where there is no real fun in store for house buyers or house sellers. The idea is to convert your house into something bigger and better by extending it sideways, upwards or downwards! Having a glass roof installed in a side or kitchen extension is a great idea not just to keep in with the building regulations but to add light and warmth to an area that is probably going to be very popular.
The type of glass roof you can use depends a lot on the extension you are going to build and more specifically the shape and type of the roof. Pitched and flat type roofs are the two most common shapes and there are glass types to suit both roof variations.
The Building Regulations, while specifying the necessity of using glazing in any extension, usually make it difficult or impossible to have too much glazing. Usually the amount of glass involved in the new structure falls between a range from twenty to fifty percent. Glass, while excellent for its ability to admit light, is generally a poorer insulator than the materials that might be otherwise used for the roof or walls of the extension. To incorporate much more glass would probably mean using amore expensive glass type with better thermal properties as well as spending more on air conditioning (in the summer) or heating in the winter.
The main advantage of glass roofs of course is the amount of light that they allow into that part of the house. The extra glass often helps to compensate for what might have been a gloomy part of the house before the extension was built. The glass roofs which are available often also help to make the whole extension more attractive both from the inside and the outside.
The disadvantages are as have already been discussed – the poorer thermal properties as well as the fact that too much light coming into the extension area can have a deleterious effect on things like furniture and décor – its common to see colours fading with too much light and the ultra violet rays which can get through the glass can cause discolouration in woodwork and varnish.
Some of the main disadvantages of glass used in roofing can be minimized to a certain extent by choosing suitable glass types. A lot of research and development has gone into glass manufacture over the years and it is possible to find glass types that are quite varied in their characteristics. The actual placing of the glass is also important. Strategically placed glass roof panels can make all the difference between being beneficial or being a nuisance one later regrets. Remember that if your extension is going to jut out sideways that the glass roof panels should be more centrally sited otherwise all the extra light will be further out than before.
