Put a hat on your home
Roof Insulation
You put a hat on your head and keep your body heat in. Thermal insulation in your roof will do the same for your house.
If you do not have insulation in your roof, up to 30% of your heat could escape, costing you money and contributing to atmospheric pollution and global warming.
If you have already insulated your roof, you may want to replace it or add another layer to improve its performance and bring it up to current Building Regulations Standards.
Types of insulation suitable for different types of roofs
Pitched roof with an attic space
If you have a pitched roof with an attic space, it can be insulated in many ways. Probably the simplest is to lay quilt, such as glass fibre quilt or mineral fibre quilt in a roll between the ceiling and a second layer in the opposite direction over the joists. If you currently have less than 300mm of attic insulation, it is advisable to increase your existing insulation to this level.
After the attic is insulated joist level, its temperature is reduced, so you must insulate the water storage tank and pipes. The water storage tank can be insulated with any semi-rigid insulating board and the pipes with closed cell neoprene, polyethylene, glass fibre and mineral fibre in pipe section form.
Flat roof
If you have an existing flat roof, insulation can be increased externally with extruded polystyrene or foamed glass, or internally with an insulated lining board such as mineral fibre or polyurethane foam-backed plaster-board.
Savings
Insulating the 50 sq.m. (540 sq.ft.) attic space of a typical house costs around €400 and could save approximately €260 a year so it would pay for itself in under two years.
