Domestic & Commercial Aluminium Windows with
‘A’ Energy Rated Options




Extruded aluminium is Aluminium Alloy 6063.T6 to BS EN 755 part9: 2001. It is constructed using mitred and mechanically crimped corners, with support chevrons and cleats to provide for accurate alignment. Integral transoms and mullions are installed by scribing the ends and then either screw fixing or bracket fixing into the outer frames. A proprietary sealant to protect against water entry is used on all metal-to-metal joints at assembly




Aluminium profiles are normally supplied coated using the powder coat method, in a wide range of colours and surface finishes, to BS EN 12206: 2004 Part 1. The SPW300 & SPW600 have the added option of being available as single or dual colour.


Aluminium can also be clear anodised in either satin or polished finish and a limited range of colours, which includes bronze and black, is also available. Anodising: i) Natural (Silver) anodised to BS3897, 1991. and ii) Anolok Bronze Colour 547 anodised to BS3897, 1991. Anodising is to a minimum of 25 microns (AA25).



Further Benefits Include :

* Compatible with the Curtain Wall Systems.

* Cockspur handles or Key locking handles with espag or shootbolt locking, with night vent facility.

* Standard friction stays with further options of egress, restricted and easy-clean facilities.

* Internally or externally glazed sash options

* Equally at home in domestic and commercial applications.


SPW300 & SPW600 are thermally broken systems using polyamide strips for improved thermal insulation. The SPW300 system is 51mm, whereas the SPW600 has exactly the same sight lines but is 75mm by using larger polyamide strips to give even better thermal insulation. Various outer frame and sash sizes and options are available to suit any application.


Originally designed for the commercial market, they have become just as popular as contemporary alternatives for the domestic market, comprising casement, tilt and turn, top swing reversible and pivoting windows. Available in single or dual colour finish. [click for SPW300 profile charts], and [SPW600 profile charts]




28mm double glazed units are standard, with a full range of glazing options, with each pane of glass individually inserted into a fully rebated and prepared opening. Glazing beads with an internal option is possible. Gasket seals to the inside create a bond between the glass and the main framing members



Thermal Performance

The SPW600 system is able to achieve an energy rating of 'A'. For both systems, varying standards of insulated glazing units, profile selection, product size and mullion spacing combine to provide a unique 'U' value per window. The most up to date designs and materials are used in order to offer the highest performance systems and products on offer in the UK.


By varying glazing specifications and system/profile selection, high insulation, specific overall 'U' values required can be achieved. It has been independently tested to BS6375, and achieved the following results:-


Air Permeability - 600Pa

Water Tightness - 600Pa

Wind Resistance - 2400Pa
