Rear of House
Traditionally Built House, Rugby

One of the questions we constantly get asked at trade shows and over the phone is “Can we use Lewis Deck on traditional build or does it have to be on a certain type of build method?”

The answer is it doesn’t matter. The only design element that we look for is what is the floor support system underneath the deck? As long as there is a timber joist, a steel beam or even a concrete beam to support the Lewis Deck the system will work.

This was the case with this project. This self build project was to be traditionally built using concrete blocks with render and timber cladding providing the exterior look of the building. The main concern for the upper floor was for it to be solid, able to reduce the sound through the floor and also, due to the type of construction, it was needed to be a safe working deck that was able to hold the weight of the concrete blocks that were needed to build the upper floor of the house.

The Lewis Deck was exposed to the elements on this project for over 3 months while the 1st floor was build and before the roof was installed making the building watertight. In this time the deck was able to withstand the rigours of the traditional build process of blocks & mortar tubs being stored on it, materials being dropped on it, heavy foot traffic and also the English weather. As you can see from the photo above the Lewis Deck has been protected by laying the blocks on a scaffold board. This is recommended so that the decks dovetails aren’t damaged during this phase of the work.

Once the building was watertight the underfloor heating pipes and screed were installed without issue, as you can see from the photographs opposite.

When it comes to this element of work all we recommend is that the deck is checked and any heavy debris is removed from the dovetails and if needed running a vacuum cleaner over it, to remove heavy dust/ dirt, prior to the screed being laid.

The Lewis Deck was installed as soon as the build got passed 1st floor level and the joists had been installed. This gave the build a safe working deck that could support the weight of the concrete blocks without damaging it.

  • 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?

    A

    If it is, this is an answer.
