Technical Specification
The main profile that we use for aluminium windows and doors are the Alitherm 600 and the Alitherm plus. This is an extremely versatile profile that can be customised to match the desired requirements. This includes the flat internally beaded sash, an externally beaded chamfered sash or the chamfered heritage internally beaded profile, for a more characterful appearance that looks fantastic on period properties.
All of our domestic aluminium windows and doors are designed to be highly performing. From the specs below you will see the performance and limitations of the Alitherm range.

For Curtain Walling, large domestic applications and commercial use, one of the most popular product profiles is the Smart Wall System. This is a narrow framed system that has been designed specifically for areas where high performance is key. This is a more robust system that extends the possibilities of what can be physically achieved without compromising on thermal efficiency. This is done by using the same Polyamide thermal break technology used throughout the Smarts range. All of the Smart wall products which feature, windows, doors and glass curtain walling can be beaded internally or externally.
