Why Install Loft Insulation?
Without adequate loft insulation you could be losing as much as 25% of your heating costs through your roof. Insulating your loft is a simple and can help you save around £350 per year on your fuel bills and around 1,200kg of CO² a year (based on an un-insulated detached home).
Loft insulation can be carried out with very little disruption. The recommended depth for loft insulation at present is 300mm, 100mm of insulation is laid between the rafters and 200mm cross-laid.
It is advisable to lag tanks and pipes when the attic is being insulated to avoid the pipes freezing in winter. Walkway boards are fitted from the hatch door over to the cold-water storage tanks for easy and safe access to the tanks. The hatch-door is insulated and draught proofed where feasible
Prior to insulation being installed one of our surveyors will call at your property and carry out a survey to determine the suitability of the property for loft insulation. The surveyor will assess issues such as ventilation, access, recess lights and the loft floor.
Before the insulation is installed our surveyor will request that all storage is removed from the attic. This is to ensure that the complete attic is covered leaving no gaps or voids which could cause cold bridges.
The Installation Process:
The recommended depth for loft insulation at present is 300mm.
- The installers will lay 100mm of insulation between the rafters and will then crosslay a further 200mm over this. Insulation will be pushed as far as is possible into the eaves without blocking any ventilation present.
- Insulation will be kept back from electrical cables and recessed lights.
- Any pipes in the attic will be lagged and tank jackets will be fitted to both the cold water storage and feed and expansion tanks. This will prevent pipes and tanks freezing in winter.
- Walkway boards will then be fitted from the hatch door to any usable service e.g. the cold water storage tanks for easy and safe access to the tanks.
- After the attic has been insulated, the hatch-door is insulated and draught proofed (provided this does not obstruct the closing mechanism of the hatch door).
Although most householders use their attic for storage, it is not recommended to continue this practice after the insulation has been installed due to a lack of heat in this area.
