Impact-resistant, rust-proof protection.

Polymer is the specialist route for environments where corrosion resistance, cleanability and a softer impact surface matter more than a traditional steel construction.

Selection and specification

Choosing uPVC radiator covers for wet areas

Polymer provides a rust-proof uPVC alternative where moisture is a key material-selection concern. Consider cleaning methods, impact exposure, mounting conditions and access requirements as well as appearance when comparing it with a steel cover.

Class 1 and B-s3,d2 come from different classification systems. Treat the wording in product literature as a starting point and obtain the applicable classification report rather than assuming the terms are interchangeable.

Supporting information: Read the Polymer datasheet. Ask Coverad about your specification.

Check the environment and material evidence

  • Describe moisture exposure and the cleaning agents used in the room.
  • Confirm the proposed mounting arrangement and any pipe or valve cut-outs.
  • Request the current fire-classification evidence and check that it applies to the proposed product and installation.

Request a site survey if you need help recording site conditions.

Frequently asked questions

What specification teams usually ask.

Practical checks to make before the current datasheet, drawings and project requirements are confirmed.

Why specify Polymer instead of steel?

Polymer is useful where moisture resistance, rust-free performance or a softer impact surface is important.

Can Polymer covers be wall mounted?

Floor- and wall-mounted configurations are available, subject to the project conditions.

What ventilation and access details should be agreed?

Review slotted or 2 mm perforation options alongside airflow, valve positions, cleaning access and the heating system requirements.

Which top profiles are available?

Flat and 30° sloping tops can be discussed alongside the mounting and site dimensions.
