A glazed or polycarbonate conservatory roof can make your conservatory feel too hot in the summer and too cold in the winter.
Glass and polycarbonate are poor insulators , and it’s quite common for homeowners to find the glare in both the winter and summer unbearable.
A Leka roof system will transform your glass or polycarbonate conservatory roof with excellent insulation set into a solid, tiled conservatory roof to create a more usable space year-round.
The Leka roof system will outperform and outlast common glass and polycarbonate roofing systems, and it has been approved by JHAI, the approved building inspector licenced by the Government. The Leka system comes with Building Control certification.
Below is an explanation of how the LEKA roof system works and is installed, providing better conservatory roof insulation, and explained to help you understand how the only roof system of its kind in the world can transform your existing conservatory or enhance your proposed new conservatory project.
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.
For a more traditional cost effective finish, standard 12.5mm plasterboards can also be utilised as part of the Leka ECO range which (in most cases) doesn’t affect our exceptional U values of 0.15.
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.
Leka outer boards have been engineered to provide:
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.
Dedicated, qualified installers
All of our Leka Systems installers have taken part in an approved installer course that ensures they are fully qualified and conversant with how the system goes together as well as the key component structure requirements to ensure the 40 year warranty is provided.
So what would we deem as a Bespoke or Character project? Here’s a quick rundown of some of our more unusual jobs:
- Insulating and cladding a rather large shed/Summer house so that it could be used as a kids’ den with a snooker table and tv
- Converting ‘many’ lean to polycarbonate roofed conservatories into tiled Edwardian or Gable shaped roofs
- Resurfacing damaged bedroom balcony floors for a lovely new fibreglass finish
- Upscaling a wooden garden gazebo so that it had a tiled roof
- We have installed insulated ceilings into several grand orangeries whilst retaining the character of the deep wooden roof bars.
It’s always interesting to learn how people will be using their new room.
We have converted a home hair salon, many Guest House dining rooms, Residential Home lounges …even a dentist! Gosh, that was fun trying to work around the dentist’s chair.
A bespoke or character project generally entails ‘space’ that needs to be revamped and good old-fashioned skilled expertise, which our team have in abundance.
