Aluminium-clad timber and uPVC windows

Internorm windows

Energy-efficient and available in either a combination of aluminium and timber or aluminium and uPVC Internorm composite windows by Cherwell deliver next generation performance and natural warmth.  

Aluminium-clad timber window or aluminium-clad uPVC windows?

We supply an extensive range of Internorm aluminium-clad timber composite windows or aluminium-clad low maintenance uPVC windows.  

Combine the structural integrity of aluminium with the timeless natural warmth of natural-woodgrain in Internorm’s aluminium-clad timber composite window range including Spruce, Larch, Oak, Ash and Walnut. 

Alternatively choose low- maintenance, ultra-energy-efficient and warm-to-the-touch Internorm aluminium-clad uPVC windows, available in a limitless choice of colours and finishes.  

The Internorm HF 410 Aluminium-Clad Timber Window

The Internorm HF 410 timber-aluminium window successfully marries the natural warmth of timber woodgrain and aluminium in a high-performance timber aluminium composite window.

Built around Internorm’s innovative I-Tec Core high-performance laminated timber system, the HF 410 is available in a choice of fixed light; tilt-before-turn; tilt; and sliding options; plus a choice of four different styles.

This includes the flush Studio finish; stepped contemporary Home Pure; softer stepped Home Soft; and more traditional and sculptured Ambiente, design options.

The Internorm HX300 Panorama Frameless Window

The Internorm HX300 Panorama is a floor-to-ceiling architectural glazing system, designed by Internorm to maximise natural daylight with the structural integrity to accommodate single openings of up to 10m2.

The Internorm HX300 Frameless Window Glazing System achieves this while still delivering exceptional levels of thermal and acoustic performance.

The Internorm KF 410 Aluminium-Clad uPVC Window

The Internorm KF 410 aluminium-clad UPVC-aluminium window brings two highly performing window materials together in an advanced, thermally efficient, and stylish offering. With minimalist sightlines, the Internorm KF 410 is defined by a contemporary squared-edged frame design, making it perfect for new build and self-build installations, with u-values as low as 0.62W/m2K. Choose from fixed light, tilt-before-turn, tilt, and sliding options.

The Internorm HF 510 and HV 450: The Epitome of Style and Functionality

In addition to the HF 410, Cherwell also offers the Internorm HF 510, an ultra-slim sightline aluminium-clad timber window that combines natural materials with a sleek design. Furthermore, the HV 450 is the ultimate in contemporary minimalist design, packed with tech including I-tec shading, Internorm’s integrated solar shading system. This system harnesses solar energy as its power source, effectively keeping your home cool even on the warmest of days.

Alongside the KF 410, Cherwell proudly offers the KF 310, an ultra-slim system with a front-to-back depth of only 74mm. The KF 520 takes minimalism to the next level with a completely concealed opening sash and a fully flush glazing sing system. Meanwhile, the KV 440 is defined by a completely flush finish between the opening and sash and frame, incorporating Internorm’s gently curved Home Soft styling. It combines style and performance with fully integrated window blind options and Internorm’s innovative I-tec Shading System, powered by solar energy to help keep your home cool even on the warmest of days.
