Technical properties of Polyurethane Replica Wood.

How is Replica Wood manufactured?

Using our high-pressure blending machinery, a pigmented Polyurethane foam is dispensed into a painted tool that has been cast from real English oak.

As the foam cures to a rigid state, it chemically bonds to the specially formulated paint. This gives the product its distinct colour and means that unlike post-painted or foiled products, there will be no flaking, peeling or blistering when exposed to the outside elements.

Our high-spec tooling and machinery allow us to manufacture to strict quality control processes that would be virtually impossible to achieve using traditional ‘hand mixing’ Polyurethane blending methods.

This unique production process gives Replica Wood all the benefits that Polyurethane has to offer – and a beautiful, authentic wood appearance that will enhance your home exteriors.

What is Polyurethane?

Polyurethane is a resilient and durable manufactured composite material that can take the place of paint, rubber, metal, wood and more in thousands of applications across virtually all fields and industries.

Since its invention during the 1940s, Polyurethane has been used in a wide range of items, from sea buoys and boat protection to air-plane wings and cushion foams – routinely outperforming plastic, rubber, wood and steel in its overall ability to resist harsh environmental factors.

Replica Wood is manufactured to a high-quality using standards and practices that comply with strict regulations and accredit registers, including;

ISO9001 – ISO14001

Thermotec Plastics are working continuously with the Warwick Manufacturing Group at Warwick University to improve the quality and longevity of Replica Wood products.

Testing was carried out at Warwick University to simulate the results of direct UV exposure over a 10-year period.

These are the results captured at 30-month intervals.

Technical Specifications for Composite Render Panels

This 3mm thick rigid aluminium lined sheet is designed for external use in the construction and industrial sector.

Sheet sizes:

  • 2440mm x 1220mm
  • 3000mm x 1500mm


Our Aluminium Composite Panels are made from a non-toxic low density polyethylene (LDPE) core,

sandwiched between two sheets of 0.3 mm thick aluminium with a Polyester paint surface finish.

These panels have excellent characteristics in lab testing such as weather-proof ability, chemical resistance, heat insulation and sound insulation.
