Evesham Trade Home Improvements Supercentre recognise that many property owners require a traditional timber window frame, sometimes due to planning, environmental restrictions or simply because they love them!

Elegant and stylish aesthetic appearance

Offering the realism of a traditional pre-1932 timber window combined with 21st century thermal benefits and more...

R7 flush windows

Featuring an elegantly flush sash appearance on both the exterior and interior of the frame gives the R7 its chic modern appearance and the versatility to be used for both contemporary modern homes and traditional heritage homes alike. R9 windows are suitable for Georgian, Victorian and Edwardian properties creating a sleek and stylish look.


The R7 seven-chamber design provides excellent levels of thermal performance and can achieve A++ energy ratings. Their profile is 75mm wide and can accommodate double or triple glazing. Residence 9 windows are so called because of their 9-chamber profiles which are designed to keep warm air in and cold air out. This system is capable of achieving energy ratings of A+


Residence 7 windows are internally beaded for superior security performance. When combined with multi-point locking, they are one of the most secure window systems available today. In Residence 9 windows the glass is bonded to the sash to further improve security levels and strengthen the overall design of the window.

A diverse colour palette is at your disposal, consisting of an eclectic mix of authentic finishes covering a number of architectural styles. Evesham Trade Home Improvements Supercentre offer everything from timeless classics like Grained White to contemporary favourites such as Cotswold Green.
