Enhanced Security

Protecting your family and your home...

The ADVANCE 70 Window System has been rigorously tested to PAS 24 and Secured by Design, thus Building Regulation Document Q and SBD compliant.

Extruded and distributed by Selecta Systems, casement windows have been designed to conform with the standard for enhanced security performance. The windows undergo forced entry attacks on the locking points using a selection of tools, including crow bars, screwdrivers, chisels, drills and blades.

Testing also includes weather performance to extreme levels, which includes testing for air and water tightness and wind loading.

Our BSi Kitemark accreditation reflects high industry standards, where tests expose the products to various extremes when installed, to demonstrate conformity, which reflects the premium quality of profiles that are extruded by the company.

Thermal Efficiency

Save £££'s on your energy bills...

ADVANCE 70 multi-chambered casement windows comply with Building Regulations Approved Document L and Future Homes Standard energy ratings scheme and U values without adding unwanted expense.

Reducing energy bills and making the home more thermally efficient is high on the list of homeowners. Understanding that fitting the right combination of profile and glass unit is of immense importance.

Excellent U Values can be achieved with a 4/20/4 28mm double-glazed unit, whilst a 40mm triple-glazed unit will increase both the thermal and acoustic performance further.

Colour Options

Choosing the right colour that blends in to your home and surroundings

Whilst many favour the bright appearance of brilliant white window frames others prefer the more natural and authentic appearance of a wood finish product. Therefore to give you the maximum choice we offer rich and luxurious Rosewood or rustic Golden Oak, Irish Oak and Mountain Oak options.

Can’t make your mind up? You could always have both with white frames on the inside to blend with the decor and a wooden finish on the outside to suit the exterior of your home.

Want a more modern or traditional look for your home? Why not choose from a palette of popular colours with Anthracite Grey or maybe a Chartwell Green, Cream or Hazy Grey?

The choice is there for you to add your own unique touch and compliment your home, whatever the style, period or location.
