SL70 Aluminium Windows

Slim Frames

Narrow sightlines of SL70 standard profile make them extremely popular with homeowners wanting to enjoy more natural light indoors!

Thermal Performance

Despite slim frames, this window can still achieve U-values from 1.0 W/m2K!

Versatile Design

Contemporary sashes are available in a range of configurations, profiles and even heavy duty option to accommodate larger sizes!


LS4600 configurations

SL70 has a wide range of customisable options to help you design windows that perfectly suit the character of your building. Or if you’re looking for windows that could replace your old, tired ones - this system, due its 70mm frame depth is a front running contender!

Customisable with a range of outward opening possibilities - top, side hung or the fixed ones, and the full suite of bay poles, cills and accessory profiles to create bespoke configurations.


More Colours

Aluminium frames can be polyester-powder coated in a wide range of RAL colours, or come in a wide range of other finishes including an anodised finish - for that metallic option, woodgrain - to perfectly imitate the natural look of timber, and event come as anti-bacterial powder coatings.

Our standard range of RAL colours covers some of the most popular customer choices for achieving that premium look. Though if you're looking for something different choose from a wade variety of RAL palette options and finishes.

For something a little bit different - choose textured coatex finish, or dual colour, where you can have different colour on the inside than on the outside!
