If you have a home with a flat roof you will want to do everything possible to ensure that the heat stays in and the cold stays out; this you can achieve through insulation. Flat roof insulation will go a long way in ensuring that your heating bills remain as low as possible. For the time that flat roofs have been around insulating them has always been quite a challenge and therefore it is important to know exactly what the entire process entails.
There are different materials that can be used for flat roof insulation namely Styrofoam, cellulose, fibreglass, mineral wool among others; different situations will call for the use of different materials. You can find a variety of different options for flat roof insulation at Roof Trader.
When insulating a flat roof it is vital to factor in ventilation and therefore it is important to have in place provisions that facilitate this. Proper ventilation will ensure that moisture does not build up in the roof; something that could lead to the formation of mould. Moisture accumulation will also compromise insulation, meaning that the heat you want to remain within the house will find a way to escape. Ventilating a flat roof requires the installation of side vents which need to be positioned in such a manner that will prevent rain water from seeping through.
Flat roof insulation also requires the use of vapour barriers whose job is to ensure that if there is any moisture remaining in the roof, it does not cause rot. Different materials are used to make vapour barriers including paper backed aluminium. This barrier will usually be placed between panels of the ceiling and the roof support.
Sometimes the insulation may not cover the entire roof; some small portions might be left open and this could again compromise insulation. It is important that once you have finished insulating your flat roof, you seal up these uncovered spaces.
Different types of insulation will require different levels of expertise to install. If you are not a building expert it would be best to call in a professional and have him do the work for you; doing so will give you better results and could end up saving you some money.
