Hybrid windows and doors

Hybrid Windows offer an entirely different proposition for glazing in the home.  Hybrid products combine all of the best features of different materials, such as timber, aluminium and even PVCu.  All these different materials come together with the glass, forming one complete product.

These innovative windows and doors offer excellent aesthetics, high performance, outstanding thermal efficiency, and a big range of products for the home.

Information about hybrid windows and doors.

Windows and doors in hybrid materials typically feature a combination of two materials, each one different on the inside and outside of the window.  For instance, there are hybrid products having coloured aluminium on the outside and wood on the inside.  There are also hybrid having PVCu on the outside with wood on the inside.

Importantly, the prominent feature of hybrid materials is the excellent thermal performance with some of the lowest U-Values and best window energy ratings. Sound insulation is also better than single materials too. Another key feature of hybrid materials is the combined strength. As a result, aluminium and timber hybrids offer bigger windows sizes and larger opening elements, compared to single materials.  With hybrid windows and doors, you also get more expansive glazing.

Products available in hybrid materials.

Virtually every type of window and door is available with hybrid materials including:

  • Windows as casement, pivoting or tilt and turn and sliding sashes.
  • Shaped, apex and gable windows.
  • Bifolding Doors.
  • Tilt and Slide and Lift and Slide patio sliding doors.
  • Single doors and French Doors.
  • Front doors.
  • Facade glazing and floor-to-ceiling windows.
  • Rooflights and roof windows

For wood-aluminium products, aluminium on the outside protects the timber inside from external weather and moisture. The wood on the inside is therefore always protected and is maintenance free.

You also get all the advantages of aluminium with the full range of over 200 RAL colour palette.  Inside, the wood comes either as natural, painted or stained. Many hybrid brands also offer a choice of aluminium capping on the outside such as contemporary, softline or shaped.

The engineering on hybrid windows allows excellent security with multi-point locking systems, corner locking and a big choice of window and door furniture.

Environmentally-Friendly Hybrid Windows and Doors.

Virtually all hybrid glazing is sustainable as we ass environmentally friendly.  The aluminium exterior is 100% recyclable.  The profile in some brands already includes recycled aluminium.  Furthermore, most hybrid systems ensure material suppliers are carefully chosen and even manufacturing processes help produce eco-friendly windows.

The wood used in hybrid windows is from sustainable sources, PEFC certified (Programme for the Endorsement of Forest Certification) or certified to The Forest Stewardship Council (FSC®) standard.   Most suppliers making these windows also adopt strict Quality Management Systems as well as Environmental Management and Audit systems.

The choice of wood finishes available inside is extensive. Engineered timber, oak, pine, spruce, larch, redwood and Eucalyptus are just some of the fine woods used.

As a result of all these environmentally friendly materials and methods, hybrid windows enjoy an extended lifespan compared to single materials.
