Durable paint finish - bespoke window colours available


Your new windows come fully finished in a factory-applied Sikkens Rubbol micro-porous (acrylic-based) system. The standard paint finishes are white gloss and white satin. A wide range of custom colours are available on request.

Our timber is always sustainably sourced


All the windows we manufacture are made in sustainably sourced timber. We use either Grade A softwood or a premium Accoya product. Softwood products are treated to protect against wet-rot, dry-rot and woodworm and carry a 10 year guarantee. Accoya comes with a 50 year anti-rot guarantee and also offers improved thermal properties.

High performance double glazing


If a Full Replacement of the Windows (including Box Frame) is required then a 4/16/4 Softcoat / Low Iron - Argon Gas Filled Glazed Unit will be installed within the Window. This type will give you the required level of heat retention and performance to comply with Building Regulations as set out in Building Control Document Part L.


Toughened glass for peace of mind and added security


All lower sash windows are installed with toughened safety glass as standard. We also toughen all glass fitted in critical locations (as set out in the Building Control Document K).


Wide range of glass options available


Obscured glass, decorative glass and acoustic glass can all be fitted in your new sliding sash windows. Acoustic glass can be particularly valuable in areas where traffic noise is higher than normal - but please bear in mind there are several considerations to take into account when using acoustic glass with a counter-balanced sash window. Our team would be happy to run through this with you in person when they visit as this is specific to each individual property.


Draught-proof sliding sash windows


All new windows come complete with draught excluders - so no more draughty sash windows! The standard range has 6.8mm brush pile draught excluders fitted to the staff and parting beads. Draught excluders are also machined into the sash window lower meeting rail. This method helps not only to eliminate draughts but also allows the window to slide smoothly.
