As temperatures drop and energy prices remain a constant concern across the UK, the pressure is on to keep buildings warmer without pushing heating costs through the roof. Effective insulation is no longer a nice-to-have – it’s essential for both comfort and cost control.

At Zouch Converters Limited, we help customers meet that challenge with high-performance closed-cell foam insulation: a lightweight, versatile and durable material that delivers excellent thermal performance across both residential and commercial projects.

Why choose closed-cell foam for insulation?

Closed-cell polyethylene foam is engineered with millions of tiny, enclosed cells that trap air and significantly reduce the transfer of heat. This structure is what makes it such a strong choice for thermal insulation, particularly where space, weight and performance all matter.

Key benefits include:

• Excellent thermal insulation – Helps maintain more stable internal temperatures and reduce heat loss.

• Cost-effectiveness – A smart, long-term solution for managing energy use and running costs.

• Durability – Resists compression, impact and environmental stress, retaining its performance over time.

• Versatility – Suitable for a wide range of commercial and domestic applications, from cavity infills to specialist components and gaskets.

Whether you’re working on new build projects, refurbishments or retrofits, closed-cell foam provides a dependable insulation option with a strong balance of performance and value.

Designed for modern insulation demands

We’ve developed our range of insulative foams to respond directly to the demands of today’s market: better energy efficiency, reliable thermal performance and materials that stand up to the real-world conditions in which they’re used.

Zouch closed-cell foam insulation is:

• Highly efficient at retaining heat, helping to cut heat loss and improve comfort.

• Lightweight and easy to handle, making it ideal for installers, manufacturers and fabricators.

• Resilient in demanding environments, supporting long service life and consistent performance.

From wall, floor and roof-related components to more specialist applications, our foams are engineered to work hard behind the scenes so the spaces you create are warmer, quieter and more comfortable.

Beyond insulation: sealing and acoustics

Although thermal insulation is a primary focus, the potential uses of closed-cell foam go much further. Its structure and performance characteristics also make it ideal for:

• Sealing – Creating reliable seals against air, dust, moisture and draughts around joints, frames, panels and enclosures.

• Acoustics – Helping to reduce sound transmission and improve acoustic comfort in both residential and commercial environments.

This multi-functionality means you can often solve several challenges with one material choice, streamlining both design and manufacture.

Formats to suit your project

Every project is different, so flexibility in format is crucial. Our sealing and insulation foam products are available in a range of configurations to suit different manufacturing processes and on-site requirements, including:

• Sheets

• Rolls

• Strips

• CNC knife-cut or die-cut gaskets

Where required, these can be supplied with or without pressure-sensitive adhesive backing, enabling quick, clean and secure installation. Whatever the format, you can rely on a material that offers strong performance while remaining lightweight and easy to work with.

Built to withstand real-world conditions

Insulation and sealing materials must cope with more than just temperature differences. They are often exposed to a variety of environmental and operating conditions, which is why our closed-cell foams are designed to be:

• Fire resistant – To support safety and compliance requirements in appropriate systems.

• Water resistant – Closed-cell construction helps prevent water ingress and moisture absorption.

• UV resistant – Suitable for applications where exposure to sunlight is a factor.

• Temperature resistant – Stable across a wide range of operating temperatures.

This combination of properties results in a robust, high-performance material that stands up to everyday use over the long term.

A consultative approach to insulation and sealing

No two applications are quite the same. That’s why Zouch Converters takes a consultative approach, working closely with customers to understand the full picture:

• Where and how the foam will be used

• The thermal, acoustic and sealing performance required

• Any environmental, regulatory or industry-specific considerations

• The production methods or installation techniques involved

From there, our team can recommend the most suitable foam grade, format and adhesive system to match your exact requirements. The result is a solution that not only performs well, but also integrates smoothly into your manufacturing process or installation workflow.
