- About CDI
Including a roof that can be used as a place to park a car or use as a terrace can prove to be a challenge, we have a number of systems that are either designed for this or can be used for this application.
Key to the success of a roof such as this is the load-bearing capacity of the system, combined with being able to provide sufficient insulation as well as not having a very deep build-up or being very heavy.
Our systems include the following:
- Large spans and high loads
- White soffit ceiling finish
- Car-park roofs
- Intensive green roofs and underground buildings
- Lewis Deck
- High load-bearing potential on timber or steel joisted structures
- Very thin concrete build-up
- Flat-roof terraces and balconies
Both a balcony and a terrace define spaces that connect the interior spaces with the outdoor areas. However, they do not designate the same space. There are a few major differences between the two and the terms shouldn’t be used interchangeably.
The term “terrace” comes from Latin where it means “earth” indicating the fact that a terrace is built on a raised plan. So basically this space is a raised flat area, usually at the top of a building or residence, but can equally be on lower levels, for example over basement or a lower level of the building
Modern-day terraces can serve a variety of purposes. They can be open gardens for example, an increasingly popular feature in urban areas. Having a beautiful garden in the middle of a busy city is very refreshing and rejuvenating. On a terrace you can also install a Jacuzzi or even a pool and turn the space into a beautiful oasis.
Op-deck is a lightweight insulated floor and roof system. The advantages of composite metal deck concrete floors and traditional rib floors have been combined in this unique patented floor/ roof system. This insulated concrete floor/ roof system (ICF) is based on traditional concrete installation but with optimal design and installation flexibility. It is suited to …Read More
LEWIS Dovetailed metal decking, as part of a joisted floor system, provides a first class solution where acoustics and fire protection are key concerns. The Lewis system works very well with screeded underfloor heating and cooling systems, allowing them to work more efficiently than without the sheets in place. LEWIS provides a number of solutions …Read More
Hody profiled steel sheets have a modified trapezium shaped profile of 60 mm in height and intended for constructing, so-called, ‘low’ composite steel decking. The finished concrete floor is between 110 mm – 290 mm high and Hody trapezium sheets can be used on free spans of up to 8 metres over the bearing construction. …Read More
Ask CDI a Question
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.
