The Architect’s Choice for Hybrid Performance
Combining GUTMANN’s excellence in engineering wood-aluminium glazing with the technical joinery expertise of The Joinery Network, the GUTMANN-LIGNUM range is a stunning collection of quality products offering superior performance.
GUTMANN-LIGNUM Wood-Aluminium clad windows offer the best of both materials: warm, tactile timber interiors and robust, low-maintenance aluminium exteriors. Homeowners appreciate the comfort and style. Architects value the precision, durability, and crisp architectural lines.
A Refined Hybrid Solution
Aluminium cladding shields the frame from weathering, while interior timber provides warmth, character, and design flexibility. Suitable for coastal, urban, or high-performance environments.
✓ High-spec aluminium profiles
✓ Natural timber interiors with modern finishes
✓ Built for low energy and high impact
Efficiency Meets Aesthetic
U-values as low as 0.8 W/m²K with the right glazing configuration, including PassivGlas, make these windows ideal for passive house and low-carbon design, without compromising on visual appeal.
Better than triple glazing: we offer PassivGlas, the latest vacuum glazing technology that is thinner, warmer and quieter than triple-glazing.
Strength & Security Where It Counts
All windows are PAS24:2022 certified, with advanced locking and high-performance materials, delivering both the reassurance homeowners need and the compliance professionals expect.
