Insulating Rooms in Roof
Recent changes to planning policies requiring higher density developments, as well as rising house prices, have led to dramatic growth in utilisation of the roof space as a living area and loft conversions. Proper insulation can make a massive difference in roof rooms all year round and make them much more comfortable living spaces.
If you have a room in a roof in an older house the chances are it will have very little insulation and will need a lot of heating in winter and be very hot in summer. Newer conversions are likely to have some insulation, but if the work was carried out before 2003 when the building regulations changed it is likely to be below current specifications. Ideally there should be 270mm of insulation and you should get a specialist to check what, if any, existing insulation there is.
The installation of insulation in loft rooms and roof conversions is a specialist task and not a DIY project as there are considerations from both ventilation and fire protection. Several different products are available depending on the roof design and construction.
