The versatile, weather-resistant panel achieving A1 classification, suitable for both semi-exposed soffit and upstand applications.

Fire Safety

With recent developments in building regulations, it is now more important than ever to consider the fire safety standards of both new and established buildings. MultiLiner has been rigorously tested in its reaction to fire, and achieves A1 classification in accordance with EN13501-1:2019.

Upstand Applications

MultiLiner offers excellent thermal properties, and can withstand extreme climatic and working conditions. MultiLiner is the ideal material for roof lining applications, where a non-combustible upstand or parapet insulation board is required to thermally insulate and protect walls in inverted flat roof systems. The standard thickness for roofing applications is 56mm overall, with other sizes available upon request. Please refer to the product brochure for installation guidelines.

Semi-exposed Soffit Applications

In both new and refurbished buildings, MultiLiner boards can be used as non-combustible insulated liner boards for the thermal upgrading of semi-exposed concrete decks. The boards that are installed improve the energy efficiency of semi-exposed concrete decks (such as those found in underground car parks and other similar applications), thus reducing cold bridging. Please refer to the product brochure for installation guidelines.


With Zero Ozone Depletion Potential (ODP) and Zero Global Warming Potential (GWP), MultiLiner boards are the environmentally responsible choice for your project.

MultiLiner boards can be painted without any special priming, using an alkali-resistant paint or emulsion. Under normal circumstances, two coats of paint give a satisfactory finish.


If the intended application requires a BREEAM rating, MultiLiner is an ideal solution. The material has zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP).
