Loft Ceilings and Walls

Walls and Ceilings in Loft Conversions

Construction of loft ceiling

An unconverted loft usually has minimal wall or ceiling coatings.

The rafters of the roof and basic cladding (sheeting under the tiles) are exposed.

Walls are insulated and finished to a high standard during the conversion from attic to useful living space.

Loft Ceilings

The space between the roof rafters usually becomes the loft ceiling and fulfills many of roles.

1. Roof ventilation - for loft occupants and roof structure.
2. Hold electrical wiring and control boxes for lights, heating and windows, and perhaps an extractor fan.
3. Insulation in loft conversions - we thermally insulate the loft to prevent transfer (loss and gain) of heat to maintain a stable room temperature.
4. Accommodate electric radiant heat mats or panels.

Roof Ventilation

Velux Air Vent

Loft ventilation provides clean air and removes stale and humid air.

Adjustable windows, skylights and ventilators are installed so they provide adequate ventillation and may be opened and closed safely.

Velux windows have an adjustable vent that may be opened partially or fully depending on ventilation requirement. Your choice of window may include type of opening - top, middle and bottom and side versions.

Extractor Fan

Adequate provision prevents excessive condensation in the roof void above the insulation. Through flow of air from 5mm continuous eave vents to 25mm continuous ridge vents eliminates condensation, the cause of rot and decay.

Building regulations provide guidance on ventilation for a healthy living environment.

Electrical Fixings

Stair light

The loft roof, before any other materals are applied, is where the electrician runs and fixes cables and brackets, so that after plastering the fixture may be assembled without need to disturb the finish.

Loft requires adequate lighting, often ceiling mounted along the ridge, typically recessed halogen and spot lights, and for indirect light along the walls.

Velux electric and automated windows and blinds are installed to a mains power source indicated in loft floor plans.

Additional features include a mains operated smoke detector, and perhaps an extractor fan.

Loft Insulation

Insulation boards with foil backing are installed between rafters.

The foil reflects heat from within the loft and from outside because roof tiles may be heated by the sun.

High quality Kingspan insulation boards prevent thermal transfer, keeping the room temperature stable in hot and cold weather.

We precision install 50mm Kingspan Insulation Boards between rafters and along ceiling ridges for maximum insulation within the loft.

Radiant Heat Mats and Panels

Radiant heating systems are generally installed underfloor, however additional heating may be installed in the joist space within walls as heating mats, or where the loft ceiling is high, as radiant heat panels.

Radiant heat is produced in waves by electric elements. The systems are very controllable, economic and space-saving, and produce a comfortable warmth when installed within loft ceilings and walls.
