This thermally efficient range is ideal for those jobs where minimising cold and condensation is a priority.

ThermalHEART technology incorporates a glass fibre-reinforced nylon insulator or thermal break between the aluminium exterior and interior elements, resulting in windows and doors that are 35% (FIRST® Metro Series) and 20% (FIRST® Residential) more thermally efficient than standard double glazed products.

Released to meet new insulation requirements for homes, ThermalHEART is a high performance system for FIRST® Residential and FIRST® Metro Series, providing maximum energy conservation and interior comfort.

The Technical Benefits

  • The ThermalHEART insulator in every profile is an excellent ‘thermal break’ to minimise the tran
  • sfer of cold and the incidence of condensation.
  • Designed to be used in conjunction with insulated glass units (double glazing) up to 24mm thick for a fully effective barrier system.
  • The jointing process for window and door extrusions ensures that the composite ThermalHEART/aluminium profiles have optimum straightness and rigidity.
  • Frames are based on a large 46mm platform ensuring suitability for a wide range of residential projects.
  • Doors are generally suitable to heights of 2.1m in ‘very high’ wind zones.
