- About CDI
We were initially contacted by the main contractors engineer regarding the use of Lewis Deck to the ground floor of Ingerthorpe Grange. The building is a grade 2 listed property just outside of Ripon, North Yorkshire.
The project was to completely renovate the internal areas of the house and bring it up to current standards. They were looking for an efficient and solid system that would allow the use of UFH on the ground floor and remove the potential for squeaky timber floors as the original ground floor timber joist and floor were damaged beyond repair.
During the rip out phase of the works it was found that the timber floor joists over the basement areas were rotten and needed to be replaced. After a discussion with us regarding the problem we suggested using the FastSlab ground floor system as its lightweight and quick install benefits would allow them to get back on programme and also allow the use of the Lewis Deck and therefore keeping the design changes to a minimum.
The FastSlab GF system is very easy to use and, as it is so lightweight and the I beams can go in at 900mm centres, it allowed us to remove weight from the floor of a very old building. The resulting effect was a very strong, solid, floor that feels thicker than the 50mm of screed that's there. The resulting UFH performance that it gives is also very impressive.
The installation commenced at the beginning of June 2016 and each room was completed in just a few hours. This included the laying of the steel I beam, the insulation and the Lewis Deck on top. The underfloor heating pipes and screed were also very quickly installed by the on site team.

What are the Lewis Deck sheet sizes?A
Q: What sheet sizes are held in stock for delivery within a few days after order? A: We stock 2500mm and 1300mm sheets. These are all 630mm wide and 16mm deep. Deliveries are made via the pallet network directly to site. The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT. 2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only) For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.Q
Lacomet – How come it has no scrap value?A
Lacomet – How come it has no scrap value? Many of the projects that we get involved in starts with a phone call or email to us from someone researching replacing stolen leadwork. Many of these are old buildings, such as schools or churches, where this isn’t the first time that the lead has been stolen and they call us fed up with having to replace it again full in the knowledge that they will more than likely go through the same problem once more in the near future if they continue to use lead. One of the big benefits that Lacomet FL brings to a project is the fact that it has no scrap value and therefore the chances of it being stolen are massively reduced. Due to the 2 thin aluminium layers, and its five layer total construction, it is of no value to thieves. Lacomet can be recycled but the polyester based coating would need to be de-laminated first and the amount of recovered aluminum is then very low, in fact it would be easier and more profitable to collect empty drinks cans than to mess about stripping Lacomet down. We can also supply stickers that can be placed in strategic locations informing people that what is now on the roof is not lead and that it has no scrap value.
Why don't my Lewis sheets interlock like they do in the video?A
Q: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.Q
Is this a question?A
If it is, this is an answer.
