Whilst there are many positives regarding WPC , customers should be aware that WPC is a compromise .
In the coastal area where I operate the market is still 50:50 with WPC more likely to be installed in higher-priced new buildings , and timber being favoured for extensions to existing homes . But both work , both can look amazing , and both offer a less costly option when looking to expand a building ’ s footprint .
ABOUT THE AUTHOR
Applications for the products have also developed beyond the original decking and handrailing uses . Fascia and corner profiles have become a standard part of the range , but more recently there has been an increase in the range and styles of cladding products available , and this offers a host of options when combined with alternative building technologies such as Timber Frame , Lightweight Steel Frame and SIPS . It is therefore possible to completely clad a structure in maintenance-free WPC cladding , including window and door reveals , internal and external corners .
Whilst there are many positives regarding WPC , customers should be aware that WPC is a compromise . Whilst is represents an effective , harder-wearing , and lower maintenance alternative to timber , it cannot be installed in the same manner as timber . WPC is not as strong as solid timber and therefore requires closer intervals for its supporting structure . Being part polymer , WPC expands and contracts with varying temperatures . This varies widely depending on the structure and quality of the boards , but an allowance of 1-2mm per linear metre is common . Whilst it is scratch resistant , WPC is not bulletproof so , whilst a dent in a timber deck might add character , the result on a WPC deck is not so flattering .
It comes down to a basic choice between traditional timber which will have a limited lifespan ( especially if not maintained ) vs a look-alike WPC alternative which will require less maintenance , offers a longer lifespan ( guarantees range from 10 – 25 years ), will not fade or rot , and features a range of colours to complement the rest of the building .

Outdoor decking and handrailing , which still represent the largest markets for this material .
