Fire Retardant Birch Plywood – Decorative

Birch Plywood available treated to Euroclass B fire performance specifically for decorative internal dry and humid applications. 

The upgraded fire performance is achieved with the factory application of an aesthetic, durable fire-retardant coating to the face of the plywood prior to installation.

The coating offers good resistance to abrasion, rubbing & scratching and meets FIRA 6205 Severe Use Rating in addition to excellent yellowing resistance. Available in either matt, mid sheen or gloss finish as required.

Careful consideration needs to be given to the method of installation to ensure alignment with the manufacturers fire certification.

Quick Reference Guide – Fire Ratings

A request we commonly receive is that for a panel with a 1 hour or ½ hr fire rating.

30 or 60mins relates to the concept of Fire Resistance and typically relates to the ability of an elevation or door to withstand the passage of a fully developed fire for said amount of time.

Euroclass relates to the concept of Reaction to Fire and focuses on initial fire growth phase. A Euroclass rated panel may form part of a fire barrier system requiring 30 or 60 mins Fire Resistance overall. We recommend that suitability of a Euroclass rated panel within the design is based upon 3rd party assessment or independent testing specific to the project in question.

There are 7 Euroclass classifications ranging from A1 to F. In line with the Construction Products Regulation (2013) each Euroclass rating requires testing against the relevant European fire test methods – see table below.

Hanson Plywood offer a range of panels manufactured with an A1 rating (see below). Untreated wood-based panels such as plywood, OSB, MDF & Chipboard typically achieve a Euroclass D or E rating. Fire rated panels can be supplied to a Euroclass B or Euroclass C fire performance as required depending upon regulatory requirements.
