Wood you believe it?
Timber is longer-lasting, better value and greener than uPVC . . . and that’s OFFICIAL.
A recent study comparing engineered timber and uPVC windows at the world-famous Institute for Building and Urban Design found:
All timber-based window frames are more environmentally-friendly than uPVC
Timber window products actually have a negative global warming potential (GWP) meaning that over their 60+ year service life they actually reduce the amount of C02e in the atmosphere
In all tests timber windows had a service life of at least twice that of uPVC windows
All timber window frames offer better long-term value than uPVC
