C & A Building Products Online

The UK's No1 independent supplier of Plastic Building Materials since 1968.


The UK's largest range of multiwall Polycarbonate and Corrugated roofing sheets held in stock. We stock a complete range of our own roof glazing bar systems with something suitable for nearly every job. We also carry a massive range of Fascia, Soffit, Cladding and Gutter systems. We constantly look for new products and add them to the range, such as the door canopy, underground drainage and many more products so please keep checking back for new products.

Many of the products we supply are not available at traditional builder’s merchants, and need special racked vehicles for their transportation. We have always specialised in delivery with our own fleet of vehicles as shown in the photo.

Take a look inside today for some great priced plastic building materials. Our aim is to offer the trade and DIY everything they need to replace, build or renovate their existing properties with the products that are usually hard to obtain, but at a cost you can afford.
