About Us

A leading provider of roofline, rainwater and building products, SIG Building Plastics bring you the highest quality range of products, expertise and advice wherever you are in the country.

Who are we?

We are the (fairly new) SIG Building Plastics division of SIG UK Exteriors. We are made up of four specialist areas of Roofline, Drainage, Sheet Materials and Windows.


With over 30 years’ experience in the industry, it combines the Roofline, Drainage and Building Plastics businesses – formerly known as Scotplas, Omnico, CFS, PBM-DQS, Summers, Armour, Roplas, Toogood, Drainex, Plastics Pipe Supplies and Project Plastics – to deliver unrivaled service, products and expertise under one name.

Why did we re-brand?

By creating this dedicated division, we are now instantly recognisable and are confident we can add even greater value to our proposition for roofline, drainage, sheet materials and glazing products. You see our new signage, in-store branding, uniforms and merchandise in your local SIG Building Plastics store – they are still the same team you knew before, just with a better offering and support to you.

How can you be confident that we have the right range of products for our customers?

Our Core Range of products have recently been developed meaning you know that wherever you are in the country, we will have the key products you’ll need in stock. Find the products included and more information here.

Outside of the Core Range, do feel free to call the branch before visiting and they can ensure your materials are ready for you upon arrival or ordered if needed.
