Insulation Formats and Conversion Options

Insulation can be supplied as sheets, rolls, pipe insulation formats, or custom‑cut components, with a range of sheet sizes, roll widths, and thicknesses available depending on the material and insulation requirements.

Custom Conversion

For more specialised applications, insulation materials can be converted into custom components using converting processes.

AS Rubber & Plastics provides a range of foam and sponge conversion services, including log cutting, laminating, adhesive slit rewinding, spooling and kiss cutting. These processes allow insulation to be supplied in shapes and sizes—including sheets, rolls and custom‑cut parts—to match specific design or installation requirements.

Choosing the Right Insulation Material

Selecting the right insulation material depends on several factors, including thermal requirements, acoustic performance, environmental exposure, and mechanical properties.

Our team can help identify the most suitable material and supply format, ensuring the correct insulation performance and conversion approach for the application.

Insulation FAQs.

What is the purpose of insulation foam?

Insulation foam is used to reduce heat transfer, absorb sound, and improve energy efficiency in equipment, buildings, and pipe systems. It works by creating a barrier that limits heat movement and helps control temperature, noise, or vibration depending on the application.

What is an insulation sheet used for?

Insulation sheets are used to insulate surfaces, equipment, or enclosures to reduce heat loss, control temperature, or dampen noise. Foam insulation sheets are commonly applied in HVAC systems, machinery housings, refrigeration equipment, and industrial assemblies.

What type of foam is insulation foam?

Insulation foam can be made from several materials including polyethylene (PE) foam, EPDM sponge, neoprene sponge, polyurethane foam, and PVC foam. Each material offers different properties such as thermal resistance, moisture resistance, flexibility, or sound absorption.

If you want to learn more about insulation options for pipe systems, read our guide on types of insulation for pipes.

Is foam sheet insulation good?

Yes, foam sheet insulation is effective because it provides lightweight insulation with good thermal and acoustic performance. Many foam materials also offer moisture resistance and durability, making them suitable for industrial and mechanical applications.

How thick should foam insulation be?

The thickness of foam insulation depends on the required insulation performance and the application. Foam insulation is available in a range of thicknesses, allowing the material to be selected based on thermal performance, space constraints, and installation requirements.

Are there different types of foam insulation?

Yes, there are several types of foam insulation designed for different applications. Common options include cross-linked polyethylene foams, EPDM sponge, neoprene sponge, polyurethane foams, and PVC foams, each offering different insulation and performance characteristics.

What is the difference between insulation foam sheets and insulation boards?

Industrial insulation foam sheets are typically flexible or semi-rigid materials used for applications such as pipe insulation, acoustic dampening, sealing, and equipment insulation. These differ from rigid construction insulation boards, which are primarily designed for building insulation.
