Fire protection in separating floors

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.

 

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?

    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.

  • Q

    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?

    If it is, this is an answer.
