What Is Loft Insulation?
Loft Insulation acts as a blanket, trapping any heat rising from the house below. The current government standard is a depth of 270mm or 11". If your loft has not been insulated in the last 10 years, it will most likely require topping up. The insulation is installed between and then across the joists.
Loft insulation decreases the amount of heat escaping through the roof. The process is quick, clean and FREE or inexpensive to install. Installation typically takes around one hour and includes insulating pipes & water tanks, in addition to insulating and draught proofing the hatch. If your water tanks are more than 1m from the hatch, a walk board will also be fitted.
The Savings
If you have no loft insulation and you install the recommended 270mm depth you could save between £180 and £220 per. year on your heating bills and nearly 1.5 tonnes of CO2. If your loft requires topping up to the recommended 270mm depth, you could save up to £200 per. year and 400Kg of CO2. These figures are provided by The Energy Saving Trust and are based on an average size property heated by gas. Greater savings can be made in larger properties or those heated by coal or electricity.
The following points are checked during a loft survey:
- Depth of insulation required.
- Area of insulation required.
- Length of pipe work to be lagged.
- Number of cold water tanks to be insulated.
- Position of the hatch relative to tanks and pipes.
- Ventilation is adequate.
- No damp is present.
