Home Insulation - Good Idea Leaflet 32

Put a polystyrene cover over the top of the water tank and run the loft insulation up the sides.

Loft floor insulation butting up to edge of polystyrene.

Cut out a piece of polystyrene insulation to accommodate the water pipe then push back into place.

To fit the foam to pipes, open the lagging and slip over the pipe. The split will re-close and can the be taped.

At tees the lagging will need to be cut and then taped together.

Make sure that where one roll of blanket loft insulation ends, the next is closely butted up to it.

You can lay 100mm insulation between the joists then cross-lay a 170mm layer on top to give an overall thickness of 270mm.

Leave a ventilated gap of about 50mm between the upper surface of the insulation and the underside of the roofing felt.

The insulation slabs can be cut using an ordinary kitchen knife to fit between rafters.

Lift the floorboards and insert insulation between the floor joists, supported on nylon garden netting.
