SP25 Roof System

A complete ‘lean-to roof’ in a pack
Master Plastics can now supply all you need to complete a lean-to roof IN A PACK. 
All you need to do is supply us with the dimensions required and we’ll do the rest. 
A conservatory is one of the most important additions to your home and the roof is the most important part of any conservatory. A strong but lightweight roof is an essential requirement as it holds the entire structure together. As well as being watertight, it has to withstand heavy snowfalls in winter and strong sunlight in summer to endure the worst of the British weather for many years, whilst still looking good. 
To ensure that your conservatory is finished with the best quality and highest performing roof possible, we are pleased to introduce the ‘ultimate’ new polycarbonate SP25 roof system.
