The conversion of the 1st floor of the Grade II listed Princes Building in Newcastle’s Quay side area into 10 apartments was carried out by local main contractors T. Manners & Sons Ltd. The building, which was designed by William Parnel who was responsible for some of the best architecture in the City, was built back in 1863 and as such posed some interesting problems when it came to bringing the building up to current standards.

In particular, the issue of acoustics from the ground floor commercial area, to the new apartment level was a concern. Because of this Lewis Deck specified by the architect due to the very high performance figures it achieves, especially when used in combination with our Sylomer TSS resilient strips.

The combination of the Lewis Deck, a minimum 50mm screed and the Sylomer meant that hitting the necessary dB figures for British Regs was taken care of and it also allowed these “luxury” apartments to have a solid “concrete” floor rather than a timber floor that would become problematic over time.


The shape of the building gave some additional issues with the laying of a floor. As Lewis Deck is made from 0.5mm gauge steel it is easy to cut allowing the deck to be laid into these shapes quite easily.

As this building is from the mid 19th Century the floor joists were positioned at very irregular centres. The Lewis Deck, as the sheets were 2500mm in length, were able to deal with is quite easily and they can be used as a safe working deck prior to the screed being laid. The existing joists were also found to be somewhat out of level as well. This posed a problem on site as the floor was to be screeded. This issue was overcome after an onsite discussion highlighting that Lewis Deck spreads the loads imposed on it across the whole floor as oppose to creating point loads as other systems do. This allowed the site team to level up the floor by thickening the concrete screed as needed.

The building was completed on time and “Level One” is now part of the City living culture of Quayside.

Ask CDI a Question

  • Q

    What are the Lewis Deck sheet sizes?


    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.


    Lacomet – How come it has no scrap value?


    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?


    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.


    Is this a question?


    If it is, this is an answer.
