Here at Colin’s Sash Windows we are not only the UK’s biggest supplier of sash windows – we sell a lot of aluminium windows and aluminium doors. Why? Well, our prices are really competitive and, more importantly, our after sales service is second to none. We select who to work with very carefully as our reputation is at stake.
We’ve chosen Smart Systems which is the UK’s biggest supplier of aluminium doors and windows.
They have a very good range of aluminium casement windows. Our biggest seller is the Alitherm Heritage aluminium windows system because we sell a lot of Heritage steel replacement French doors in this range so you can match your windows and door. Inspired by the aesthetics of traditional Steel windows, Alitherm Heritage features signature slim sightlines and attractive contours making it the ideal choice for heritage building conservation areas where building regulations demand a like-for-like replacement. We have another option for slimline aluminium windows – our Smart Alitherm 300 range. This option is slightly cheaper than the Alitherm Heritage range. We also offer aluminium flush casement windows – these are the Alitherm 500. A top quality side hung or top hung system.
Our aluminium double glazed windows are suitable for domestic or commercial applications as replacement windows for existing building, and for installations into new buildings. Aluminium casement windows offer strength and durability and don`t rust. The aluminium window frames utilise an innovative polyamide thermal break technology, which creates a barrier between the cold air outside and the warm air inside providing high thermal efficiency. Aluminium casement windows are a top choice for many households because of their sturdiness and low maintenance needs. With toughened glass they provide extra security and peace of mind. They can greatly reduce the noise that is coming from outside and give you a peaceful home.
