Insulation and Heating within Converted Lofts

Loft Insulation and Heating

Insulating and heating your loft will provide heat, comfort and fuel efficiency and cost savings.

TopLoft Insulation

Loft insulation materials work by preventing the movement of heated air out of the loft. The loft becomes a well-insulated box for your comfort and safety.

The type of insulation installed and manufacturer's materials chosen depend on what part of the conversion is insulated:

  • Under floor insulation- between floor joists
  • Party wall insulation (behind a timber frame partition wall)
  • Ceiling and wall insulation (between rafters)

Floor Insulation

Between the floor joists we lay 250 mm glass fibre Gyprock Rockwool (or similar) insulation. This is in accordance with building regulations for thermal, sound, fire and high temperature insulation.

Rock-wool thermal insulation prevents heat loss, draughts and unwanted heat from the rooms below, but essentially it provides a 30-minutes fire retardant insulation.

Ceiling and Wall Insulation

Heat travels upwards so we obtain the maximum benefit from thermal insulation using 50 mm Kingspan foil backed insulation boards (reflective aluminium faced and backed rigid insulation board). These are high quality insulating boards designed to fit between roof rafters and partition frames in order to insulate within walls and ceilings.

Party Wall Insulation

Party walls or end of house walls are identified as plain brick. These walls are insulated with Kingspan rigid insulation to minimise heat loss, maximise sound proofing and provide 30 minutes of fire-safe insulation resistance.

TopLoft Radiant Heating

Electric radiant heat is the modern way to heat loft conversions, especially if your existing heating system is unsuitable for upgrade.

Radiant heating systems provide safe, comfortable, space-saving underfloor heating that is efficient and very controllable.

Installation of radiant heating is generally more efficient than an upgrade to an existing central heating system. It is also more flexible.

Radiant heat is thermal energy emitted from underfloor or ceiling electrodes. Energy waves warm surfaces such as floor tiles or wooden floors, ceilings and furniture, these warm the air.

Radiant heating systems are very efficient, they have programmable controls, safe operation and zero maintenance making them ideal for lofts and loft bathrooms.

Options include installation of underfloor heating cables or mats and wall or ceiling panels.
