Alitherm Heritage

We designed and developed the Alitherm Heritage ranges specifically to meet the requirements of refurbishment and renewal projects, particularly in sensitive planning areas. Ideal for Victorian and Art Deco projects, the range of commercial and residential windows and balcony doors is already proven in a wide range of renovation, refurbishment, and heritage projects across the UK.

These include:

  • Increased Lifespan
    Because aluminum does not rust or rot, window frames provide great longevity and can last indefinitely.
  • Improved Thermal Efficiency
    Modern aluminum windows are thermally broken using polyamide, an excellent insulator that helps to insulate windows against heat loss
  • Reduced Maintenance
    Maintenance for aluminum systems is simple and straightforward, with a routine ‘wipe-clean’ all that is required to keep the products looking their best
