Step 1 – GRP Rafters
First, ‘Glass Reinforced Plastic’ rafters are added to your existing conservatory window frames, including a GRP structural ring beam, rafters and ridge. GRP is not prone to:
- wood worm
- moisture absorption such as traditional timber
- thermal bridging such as bulky Aluminium alternatives.
The beginning of your improved conservatory roof insulation.
Step 2 – Internal Leka Boards
Next, internal Leka sheets are added underneath the GRP rafters. The Leka sheets are 100% waterproof and one third the weight of plasterboard.
These sheets have unique thermal qualities as well, but allow for a traditional plaster skim finish to provide a nice visual aspect ready for painting afterwards.
Step 3 – Celotex Insulation
Insulated Celotex sheets are snugly fitted with a 15mm gap from the internal Leka sheets. Celotex is one of the UK’s leading insulation specialists, providing high value thermal efficiency and BBA certified and a significant benefit in achieving a better conservatory roof insulation efficiency level.
Step 4 – Outer Sheets
Next, strong, load-bearing and insulated outer sheets are added. These ensure less roofing bars and higher efficiency.
Our Leka outer boards have been engineered to offer:
- A structural alternative to plywood
- A significantly lighter alternative to any other roof covering board
- A 100% waterproof outer covering
- A thermally efficient board
Step 5 – Tiling
Finally, a high quality Tapco or Metrotile roof is added.
Both Tapco and Metrotile offer a classic roof finish dependant on your property and required cosmetic look.
These lightweight alternatives to concrete tiles or slate really do make the LEKA systems overall finish stand out as much as the main structures attributes do.
