Timber-Aluminium Glazing Solutions.

Timber-aluminium is a high-performance window and door material that merges the warmth and character of real timber with the durability and weather resistance of aluminium. Whether you're specifying for a Passive House, upgrading a family home, or working on a high-end architectural project, this hybrid material delivers on thermal efficiency, design flexibility, and long-term value.

🪵 What Is Timber-Aluminium?

Timber-aluminium combines:

Solid timber interior (typically spruce, oak, larch, or walnut) for insulation, elegance, and a natural aesthetic.
Powder-coated aluminium exterior to protect against moisture, UV rays, and corrosion with minimal maintenance.

Together, these layers produce a stable, energy-efficient frame suitable for both windows and doors.

How It’s Made

Timber Core – Precision-milled timber is finger-jointed or laminated for structural stability.
Surface Treatment – Timber is primed, sealed, and coated to resist warping and moisture.
Aluminium Cladding – Extruded or formed aluminium is colour powder-coated and mounted to the exterior.
Assembly – Internal bonding, thermal breaks, seals, and triple glazing are integrated for superior energy efficiency.

🎯 Why Choose Timber-Aluminium?

Energy Efficiency: Naturally insulating timber + protective aluminium shell = exceptional U-values, airtightness, and Passive House suitability.
Design Freedom: Match traditional or contemporary homes with flush, stepped, or minimalist frames, unlimited shapes, and colour choices.
Low Maintenance: The timber stays protected indoors, while aluminium shields the external face from rain, sun, and pollutants.
Sustainability: Timber from renewable sources + recyclable aluminium = a low-carbon, future-proof choice.

Performance at a Glance

Timber-aluminium systems are engineered for outstanding performance in thermal insulation, airtightness, and durability. Below are typical figures across our product range:

U-values as low as 0.64 W/m²K (Internorm HF520)
Acoustic insulation up to 45 dB (Drutex Duoline 88)
Air permeability: Class 4 (EN 12207)
Water tightness: Class E1200 (EN 12208)
Wind resistance: Class C5/B5 (EN 12210)

These figures make timber-aluminium an ideal solution for Passive House and EnerPHit-standard homes.
