Introducing Thermal-Break Technology To Aluclad Windows

Aluclad Window Cross Section Detail

The black polymer thermal break prevents water from lodging between the aluminium cladding and timber, guaranteeing your window investment will last for decades.

  • Impermeable Thermal-Break Between Cladding & Wood: Signature’s Aluminium Clad Wood Casement Windows consist of a black thermal-break polymer which enhances insulation performance by at least 35% and doubles overall water-tightness.
  • Effective Drainage Holes: Water that passes between the exterior cladding and polymer thermal-break can escape through drainage holes to prolong the lifetime of your windows.
  • Ultimate Water-Tightness: Signature boasts a water-tightness rating of 1200 pascals which is 2X better than maximum CE standard of 600 pascals which most high-spec aluclad products qualify for.
  • Cost-Effectiveness: Signature’s Contemporary Slim Aluclad Windows can achieve Near Passive Standards in double glazing or Passive in triple glazing at great value, reaching thermal and air-tightness performance that helps reduce energy consumption bills.
