Warm Roof Loft Insulation

Insulating your loft attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.

Warm roof loft insulation.

Interestingly the opposite effect happens in summer. The materials used to insulate under the roof include batts of mineral or glass wool insulation held in place by battens of wood attached to and across the rafters. You should leave the space under the roof tiles free from insulation to give adequate ventilation so that you don t get condensation or water coming through the tiles. Warm loft insulation is used on pitched roofs where you are using the loft space as a room or for storage.

Layer more insulation over the old for more effectiveness. In most cases the attic is ventilated and the infiltration barrier is the drywall ceiling. It can either be laid between the joists the horizontal beams along the floor of your attic or the rafters the angled beams that support the roof. If you live in a warm climate you require a lower r value.

Roof ceiling insulation insulation in roof ceiling constructions must be placed in direct contact with the infiltration barrier. In this case the insulation must lie directly on top of the ceiling. The insulation boards are placed in the space between the rafters in the loft and act as a protective layer against the cold outside whilst keeping the warm air inside. Increase your r value by layering insulation.

The format of house insulation you need depends on where you put it and if you need to control. Loft insulation is effective for at least 40 years and it should pay for itself many times over. Cold areas require a higher r value like an r 49. The insulation is installed under the roof in the slope.

Types of warm loft insulation. A warm loft is where you insulate immediately under the roof which means your loft space is warm as well. Insulation slows down the transfer of heat from low to high and from warm to cold. A cold loft is where you insulate immediately above the ceiling of the top storey so no.

If 180mm is to be installed then 100mm board might be introduced between the rafters there has to be a minimum 25mm air gap between the insulation and the underside of the tiles or slates with an 80mm board running across the rafters. With a warm roof the usual process is to split the insulation into two layers. Loft insulation is a barrier of material within your roof space. Alternatively polystyrene slabs that are sometimes foil covered can be fitted.
