- Compression packed for easier handling.
| Thickness (mm) | Width x Length(mm) | Area per roll (m2) | R-Value (m2K/W) | Thermal Conductivity (W/mK) |
|---|---|---|---|---|
| 100 mm | 1140 x 12180 | 13.89 | 2.25 | 0.044 |
| 170 mm | 1140 x 7039 | 8.01 | 3.85 | 0.044 |
For safety, work from suitable 'crawling boards' spanning four joists. You should wear a face mask, eye protection and gloves to prevent any irritation.
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.
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 170mm Space Combi-Roll (or 200mm for even higher energy savings).
STEP 5- Insulate the loft hatch, install a retaining bolt and draft seal the hatch.

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 all 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 overheating.
