Established in Lancashire in 1993, GAP has grown impressively year on year, supplying both the residential and commercial building markets with low maintenance PVC-U building products. GAP's success is thanks to you, our customers and our loyal committed team, who excel in what they do. In August 2017 we acquired SIG Building Plastics and SIG Windows, meaning our depot network doubled in size and extended our reach across the nation. From Inverness to the Isle of Wight, we're pretty sure a GAP depot isn't far away. We operate an extensive network of trade counters across the country, serving thousands of customers on a daily basis. Whether our customers are looking for convenient next day delivery or an express Click & Collect service from any of our fitter friendly trade counters, we have the service, stock and trade prices to impress. We also provide free hot brews, so it's worth stopping by and seeing why we're different.Here at GAP, we manufacture a huge amount of what we sell - almost 65% in fact, from over 500,000 sq-ft of high tech production facilities in the group.Homeline Building Products produce top quality BBA and BSI approved PVC-U rooflines and claddings. We've invested huge sums of capital to ensure our state of the art extrusion plant is amongst the most efficient in Europe. We're particular proud that our engineers and technicians at Homeline developed the UK's first and only range of BBA approved recycled Rooflines called ‘Core'.GAP is the home of Rockdoor and we feel it deserves a special mention. When Rockdoor was created by GAP in 1996, our intention was to create the most secure and thermally efficient door available. 24 years on and 1 million doors later, Rockdoor continues to lead the market keeping families safe and secure.
