Timber Effect PVCu Windows

FlushSASH – the timber look

These traditional style products are crafted using environmentally friendly lead free PVCu profiles, and can be specified with energy efficient double or triple glazed sealed units for optimum energy performance.

Our FlushSASH timber effect PVCu windows have achieved an A+5 energy rating, making them the perfect choice for the energy-conscious consumer looking to replicate their current window design or to put the original style back into their property.
