- About CDI
Fire separation within floors is a key component of achieving the performance required to allow the evacuation of a building during a fire, this is expressed as a time in minutes and is typically 30, 60, 90 or 120 minutes. Different building types require different levels of performance. Typically in houses this doesn’t kick in until the property is 3 stories or higher.
Building Regulations
The regulations exist today embedded in the Building Regulations. In England and Wales, the fire regulations are known as Part B. In Scotland and in Northern Ireland, the relevant section is Part E. They are much the same in all parts of the UK.
- Scotland’s regs can be viewed at scotland.gov.uk
- Northern Ireland’s regs can be viewed at dfpni.gov.uk
- England and Wales regs can be viewed at planningportal.gov.uk
If you have a specific requirement that isn’t addressed by one of our standard build-ups, please feel free to get in contact to discuss the requirement, we also have an engineer on hand to provide extra guidance should it be necessary.
Our systems can achieve up to 120 minutes of fire protection, with 60 minutes being the standard performance achieved with simple construction build-ups.
Typically the fire rating is a combination of the full floor build-up from ceiling through to the top of the floor, but we are also able to provide details for fire resistant floors that incorporate exposed timber beams.

Q
What are the Lewis Deck sheet sizes?
AQ: 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
Why don't my Lewis sheets interlock like they do in the video?
AQ: 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.
