Description

Thermally broken, aluminium, single or double doors 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.

The elegant, robust and high-performance entrance doors available in a range of formats and sizes. Designed for ease of fabrication and installation, Alitherm Plus doors feature adjustable hinges and lock keeps, with additional clearance for sash-passing to provide greater fitting tolerances.

Alitherm Plus can be fitted with the Smart Designer Door Panel range, which is carefully selected to suit a wide range of house and apartment styles. It is available in a choice of standard and non-standard colours, with single and dual colour options including Smart’s own Naturals, Sensations, Alchemy and Cotswold colour ranges.

Features and benefits:

  • An enhanced system designed to comply with the revisions to the Building Regulations (E&W), Document L compliant.
  • Marine grade 1.4401 (316) marine grade stainless steel hardware option.
  • Profiles feature an extended polyamide thermal break to enhance thermal performance.
  • Single and double door options.
