SPACE BLANKET

Space Blanket is a premium ‘encapsulated’ glass mineral wool product for use between 400mm ceiling joists or on top of existing insulation. The sleeved encapsulation is a part metallised polythene film that reflects heat and makes it extra easy and comfortable to install. It is also ‘compression packed’ for less handling - expanding when unrolled.
  • Easy to handle and encapsulated for more comfortable installation.
  • Can be laid on top of existing insulation.
  • Correctly installed will greatly improve the thermal efficiency of your home.
  • Could pay for it’s self in under 2 years from energy savings

Installation Instructions

For safety, work from suitable 'crawling boards' spanning four joists.

STEP 1- Start from the eaves ensuring the wall plate is covered and work towards the center of the loft, placing 100mm between the joists (on top of any existing insulation in place). Butt joint where necessary.

STEP 2- When space along the joists is filled, the end of the roll can be turned back to start an extra layer of insulation or may be cut to size. If cut, glass mineral wool will be exposed.

STEP 3- Layer insulation to the required thickness ensuring the ceiling beneath is completely covered except directly under the water tank.

STEP 4- Where the depth of previously installed insulation has reached the tops of the joists, extra heat saving is gained by 'cross layering' (at right angles to joists) with 150mm Space Blanket (or 200mm for even higher energy savings).

STEP 5- Insulate the loft hatch, install a retaining bolt and draft seal the hatch.

Don't forget - lay Space Blanket silver side up

Tanks & Pipes

Fasten loft insulation all around and on top of your cold water tank to protect from freezing. Do Not insulate directly underneath the water tank. Wrap water pipes to protect from frost.

Electricals

Insulation must not be laid over electric cables. Carefully, lift electrical cables above the insulation so that they do not overheat. Ensure there are no loose or disconnected wires and re-route them if necessary. Insulation should be kept at least 75mm away from recessed light fittings and hot flues to prevent them from overheating.
