Internorm Timber/Aluminium Windows & Doors

Internorms timber/aluminium windows are an unrivalled, premium system and are a highly popular choice among homeowners in Berkshire, Hampshire, Surrey, and Oxfordshire for home renovation and new build projects.

They are eco-friendly and energy-saving, and unrivalled in elegance and style.

The combination of long-term durability, superior craftsmanship, and exceptional thermal performance makes aluminium-clad windows ideal for contemporary builds and passive houses.

The F stands for Fenster, the German word for window, and the H stands for Holz, the German word for wood.

Internorm offers bespoke timber/aluminium windows that withstand all weather conditions while preserving the beauty, naturalness, and warmth of wooden windows.

Internorm offers a range of sustainably sourced timber finishes, including Spruce, Oak, Larch, and Walnut, to match your home’s aesthetic.

Internorm is renowned for its exceptional Austrian craftsmanship and the use of premium-quality materials. The sustainable, pre-treated timber, free of knots, offers outstanding thermal insulation, as well as high-quality, external, weather-resistant aluminium cladding for maximum durability, with minimal maintenance.

The outer aluminium clad protects the timber from peeling or fading while helping the windows achieve impressive low U-values of 0.62 W/(m²K). Available in a wide range of colours.

Timber-aluminium composite windows that meet Passivhaus standards are available, incorporating additional I-Tec Ventilation for enhanced security, as well as excellent thermal efficiency and acoustic insulation.
