Application

It is the ideal solution for heritage applications such as listed building renovations and large-scale replica-refurbishment projects where planning constraints are to be considered.

Description

Thermally broken, aluminium, side-hung, top-hung, fixed or tilt and casement window system incorporating innovative polyamide thermal break technology, which creates a barrier between the cold air outside and warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U-value of the product.

Alitherm Heritage is available in a choice of standard and non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodized effect finishes.

The Alitherm Heritage window is designed to be built as a series of horizontal modules which can be stacked using horizontal couplers to form a multi-part window featuring a specially designed drip bar between modules.

Features and benefits:

  • An enhanced system designed to comply with the revisions to the Building Regulations (E&W), Document L compliant.
  • BRE Green Guide A+ Rating.
  • System can achieve Window Energy B Rating.
  • Marine grade 1.4401 (316) marine grade stainless steel hardware option, along with Heritage and Art Deco.
  • Polyamide thermal break provides enhanced thermal performance.
  • Designed as a direct replacement for steel windows.
  • British Standard Kitemarked system – KM 81580 and KM 81543.
