- About CDI
CDI Innovative Construction Materials evolved out of a family business set up by Ian Larnach in 2002 called Ian Larnach Associates (ILA). Initially ILA ran as a construction consultancy business to help introduce new products into the industry as well as providing sustainability and Code for Sustainable Homes services. Ian initially discovered Lewis Deck on the back of a visit to a trade show, in Birmingham. Within 4 weeks Ian had a contract to import Lewis into the UK.
The Lewis Deck very became the strongest product that ILA dealt with and as a result CDI (Northern) Distribution (a partnership business) was set up in 2009 as the distribution body for the sheets with Chris Holt as MD.
Since 2012 the company has seen year on year growth and it naturally evolved into CDI Innovative Construction Materials Ltd as more and more products were added to our portfolio. As well as Lewis Deck we offer a number of construction solutions from Reppel bv, the manufacturers of the Lewis sheet, as well as having our own construction solutions (see “Our Systems”).
CDI has the exclusive distribution rights for the Reppel suite of systems for the whole of the UK and Ireland
Ian retired from the business in early 2016 due to ill health, and Paul Larnach joined the company as a director to help the business grow further.

Ask CDI a QuestionQ
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.
