Building Fabric - Walls, Roofs, and Floors

Insulation:

Proper insulation will help retain valuable heat and improve overall comfort levels. If insulation is disturbed or damaged at any time, e.g. in attic space, make sure to restore or replace it.

Roof:

The roof is one of the largest areas for heat loss in a dwelling. Installing insulation will reduce this heat loss, and so reduce the energy demand of the dwelling. Blanket insulation, loose beads or expanding foam may be used to achieve the required insulation level.

Walls:

As the largest surface area in most dwellings, the wall can make up one of the largest areas for heat loss in a dwelling. Installing insulation will reduce this heat loss, and so reduce the energy demand of the dwelling. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall.

Floors:

The floor can be a source of significant heat loss and dampness in a dwelling. Installing insulation will reduce this heat loss, and so reduce the energy demand of the dwelling. The floor space must also have adequate ventilation to prevent dampness.
