- About CDI
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 insulated, high-load-bearing applications including car park roofs, intensive green-roofs and suspended high load floors including supermarkets, hospitals, etc.
An Op-deck system can be laid on supporting structures of steel, concrete, brickwork, wood, etc. The Op-deck sandwich floor panels function as permanent shuttering for a relatively thin reinforced concrete floor with a free span of up to 10 metres maximum.
Op-deck comprises a sandwich panel made from thin profiled steel sheets with PIR foam insulation. EPS profile blocks on the sandwich panel ensure further weight reduction and turn the floor into a concrete floor of the T-beam principle (concrete rib floor).
Both components, the sandwich panels and the EPS profile blocks are installed on site. The result, after the reinforcement and concrete have been applied, is a lightweight insulated concrete floor with a large free span, small constructional height and a smooth white (RAL 9002) underside of flat sheeting, which functions as a ceiling. It is possible to include under floor heating or a complete energy management system in the Op-Deck insulated concrete floor.
The Op-Deck System:
- Thickness of finished concrete floor from 250 mm.
- Low own weight (from 190 kg/m2).
- Free span up to 10m.
- High permissible load (Prep).
- High bearing capacity at point load (Prep).
- Flexible system construction.
- Fire-resistant (Resistance to Fire Penetration and Fire Transfer) = 60 minutes.
- Insulating floor (Rc > 4 [m2.K/W]).
- Strut-free installation (max. 5.5m).
- Simple and fast installation.
- Easy logistics at the building site.
Op-deck sandwich floor panels and the EPS profile blocks are simple to process. An installation procedure is available. Optionally specialized application companies are available to install the Op-deck insulated concrete floors.
If you have any questions regarding the system please contact our technical team.
"Using Op-Deck meant that we could incorporate a car park on the roof of the store as we were struggling for space to hit the planning requirements on the ground"
Op-Deck sandwich floor panels and EPS profiled insulation blocks are quite simple to install, the fixing details are available on request. If required we can arrange installation through a nominated specialist contractor.
Op-Deck design software has been specially developed for the system to provide details of the optimum cross section based upon performance and design details provided by the client. As well as providing a load bearing structural floor Op-Deck provides up to a 60% reduction in weight against other floor systems. As a result the total cost of a project can be reduced considerably.
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.
