A multi-purpose building panel with excellent thermal and moisture performance.
Multi-Pro is a medium density multi-purpose Magnesium Oxide board which is highly durable and vapour permeable. It is suitable for semi-exposed, external applications where exposure to moisture may occur providing the boards are correctly primed and painted prior to fixing.
This board is used in applications which require the amalgamation of sound insulation, moisture resistance and fire retardant performance.
Multi-Pro is manufactured using a low carbon, low energy manufacturing process. The boards are naturally cured using a chemical reaction, low levels of heat and a lengthy drying out stage.
Multi-pro has the capability to act as an internal hygroscopic buffer which in turn assists in the controlling of humidity.
This product is a breathable, hygroscopic and capillary active material, which are crucial environmental properties to take into account when designing air tight dwellings and retrofitting of solid wall ‘hard to heat’ homes. The breatheability of the product allows for the absorption and release of moisture which provides a safer and healthier working environment and overall structure.
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.
