Wide range of uPVC window styles available to suit any application

uPVC windows are no longer restricted to the standard casement style that we have all become so used to.

The potential for uPVC window styles should not be overlooked, modern systems allow uPVC to be used in the construction of authentic traditional looking flush casements to suit town houses and country cottages alike. uPVC slimline systems are now also available as a cost-effective alternative to aluminium in a wide selection of colours which can be tailored to suit modern or traditional projects.



Huge choice of finished window colours & effects available

Not all uPVC needs to be white, nowadays modern manufacturing processes allow for foil finishes such as natural woodgrains, painted woodgrains and smooth coloured finishes to be applied.

When combined with the wide choice of window styles available these foil effects can transform a standard uPVC window into an extremely elegant solution for your home.
