A high strength, external render carrier board which offers an alternative to block and render, brick, masonry or cladding finishes.

Multi-Rend is a vapour permeable, A1 non-combustible magnesium oxide building board which offers excellent dimensional stability while boasting the ability to resist moisture, frost, mould and impact.

The product is particularly suitable for external facades for structures which utilise timber, steel or hybrid framed structures. Using Multi-Rend proves to be a lightweight, thermally efficient alternative to most render carrier boards.

Typical Applications
  • Render carrier board for the following render systems:
    • Silicone
    • Acrylic
    • Cement
  • Render carrier board for the timber/steel frame structures
  • Modular Construction
  • Pre-Fabricated Caravan Construction
  • Park Homes
Product Features
  • A1 Non-combustible
  • BBA certified
  • Breathable
  • Impact resistant- In accordance with ISO 7892
  • Low Thermal Expansion
  • High strength to thickness ratio
  • Lightweight
  • Easy Cut – Score and Snap
  • Keyed surface
Environment

Multi-Rend 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-Rend 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.

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.
