Sustainable Products

We are committed to minimising the environmental impact of our products throughout their lifecycle. Our use of recycled PVC provides low-embodied carbon products for customers and prevents PVC waste from going to landfill. We also focus on developing thermally efficient products that help our customers minimise heat loss and reduce their energy costs.

Recycling operation

We are proud to be a leading UK-based recycler of PVC windows. Our extensive recycling capacity sits at the heart of our operations, our sustainability strategy, and will be critical to our Net Zero ambitions.

Our recycling operations process post industrial and post-consumer waste into recycled material, c.60% of which is then used in our own operations to produce our products.

Most of the remaining by-product is scrap metal, which is sold to metal recyclers, with very little sent to landfill.

Recycling operation benefits:

• Commercial: Addresses customer demand for sustainable, low-carbon products
• Economic: Increases profits when the production cost of recycled compound is lower than the purchase price of virgin PVC compound
• Carbon savings: Lower-embodied emissions of recycled material are crucial for Net Zero transition and meeting SBTi targets.

2025 performance:

• 27.6k tonnes of post-consumer waste and 8.4k tonnes of post-industrial waste recycled
• 16.0k tonnes of recycled materials were used in manufacturing our rigid PVC profiles, and 5.4k tonnes used in 100% recycled products or sold to trade extruders
• Recycled PVC represented 30% of total raw material consumption (2024: 32%), with the small reduction reflecting product mix and lower volumes, as well as some unscheduled plant downtime caused by equipment breakdowns.

Our ambition

Our ambition for PVC extrusion is to achieve 36% recycled content by 2030, and this represents an important part of our Net Zero Transition Plan.

Delivery will be dependent on several factors such as:

• Operational capacity – increased recycled content will likely require further investment in co-extrusion capacity and tooling
• Supply of recycled feedstock – to reach our recycled content target, alongside our sales growth ambitions, will require an increase in feedstock supply at acceptable purchase prices
• Legislative limitations – we will need to monitor any future changes in legislation and understand the potential impact on our targets
• Technological limitations – it is not currently commercially viable to use large quantities of recycled PVC in foam profile products.

As described above, we will review how the Alunet group of companies fit into our Net Zero transition pathway during 2026.

The percentage of our revenue from low carbon products this year was 21% (2024: 22%). This represents all products that are co-extruded (contains recycled and virgin PVC content) or 100% recycled. Likewise, 38% of Alunet’s revenues in 2025 were from low carbon products (defined as containing recycled aluminium).

Thermally efficient products

Our window and door products are designed for enhanced thermal efficiency through low-thermal conductivity, measured by U-values. Our mainstream PVC fenestration products meet the proposed Future Homes Standard level of 1.2 W/m2K, with some products reaching as low as 0.8 W/m2K. For Alunet Systems, the Aluna+ window is designed to exceed current building regulations, achieving a U-values as low as 1.3 W/m2K with standard double glazing, and 0.9 W/m2K with triple glazing.

End of life

It is our aim to continue to recycle as much PVC as possible, moving where practical towards closed-loop recycling, whereby windows and other PVC profiles are continually recycled into new products. Our PVC profiles can be recycled up to ten times and have a life span of around 100 years. While products manufactured by Alunet Systems are not currently recycled, the aluminium we purchase from our two biggest suppliers is 75% and 53% recycled respectively.

We source raw materials and traded goods from manufacturers worldwide. We have systems and processes in place to maintain ethical and sustainable relationships. These include pre appointment checks, in-life supplier reviews and contractual provisions for compliance with regulatory standards. The Head of Procurement manages supplier relationships and value chains.

Our goal is to provide high-quality products and services that satisfy our customers’ requirements. We conduct thorough testing on all products for both quality and product safety reasons. We aim to continuously improve our performance and adhere to ISO 9001 and other quality standards. All our manufacturing sites are accredited to ISO 9001, except for Alunet Systems, where the objective is to undertake the accreditation process in 2026. We also provide training and support to our colleagues, so they are able to play their part in delivering high standards for our customers.
