Aluminium Innovation

For decades, we’ve been at the forefront of product development and our ideas have been rewriting the way in which windows and doors are made.

They have enhanced appearance, improved security, transformed thermal performance and safeguarded more of the Earth’s precious resources. Stellar is a prime example of our commitment to innovation.

Stellar is:

  • The only system with the patented reverse butt joint solution
  • Quicker to glaze thanks to its patented knock in bead
  • 30% Slimmer than all other aluminium systems
  • Clean lines, adaptable style with both-sides-flush capability
  • 20% faster and simpler to install
  • Highly insulated without the high price tag
  • Efficient use of materials and responsibly produced
  • Practically maintenance free.

New Thermal Break Technology

The special polyamide thermal break technology delivers a highly thermally insulated window that achieves a U-value as low as 0.95 W/(m2K).

  • Special polyamide
  • Under glass seal
  • Tailed glazing gasket
  • Frame centre seal

Designed to meet Part L requirements, improve insulation and weather protection without the use of foam.

Stellar’s designers accepted the challenge of developing an extraordinary system. Years of experience were combined with an open mind and high ideals. Every aspect was evaluated, discussed, prototyped and tested.

The results speak for themselves.
