Mayplas Thermal Soffi t achieves A2 Reaction to Fire classifi cation
M
ayplas’ Thermal Soffi t, just launched in March, has now achieved an A2 Reaction to Fire classifi cation and
has been renamed ‘Thermafi re A2 Soffi t’. The product is part of a range of insulation that Mayplas, a specialist manufacturer in passive fi re protection, acoustic and thermal insulation, off ers the housebuilding and construction industries.
Confi rmed following testing as Reaction to
Fire A2-s1,d0 according to BS EN 13501-1, the limited combustibility slab provides thermal and acoustic insulation within the soffi t at the party wall junction. Available in thicknesses of 100 mm and 150 mm, permitting the design of thermal performance to suit the construction, the Mayplas Thermafi re A2 Soffi t facilitates thermal resistance values to Approved Document L. It is suitable for both masonry and timber frame constructions. It also provides resistance to the passage of sound, synonymous with stone mineral wool insulation. Standard 600 mm x 600 mm slabs can be
cut to size on site to ensure an accurate cut to fi ll the full soffi t void at the party wall. The soffi t can be secured through the product to the timber truss or masonry block using the correct length of fi xing for the width of the product. Mayplas can supply appropriate fi xings. In terms of application, the Thermafi re
A2 Soffi t is valid for any wooden-based substrate and is also valid with or without a cavity to the opposite side. “Achieving an A2-s1, d0 Reaction to Fire
classifi cation for our Thermafi re soffi t product is proving very useful,” comments Michael Hunter, Mayplas’ technical director. “The test results open up new applications which we look
forward to exploring with our housebuilder customers and with the construction industry more broadly.” The Thermafi re A2 Soffi t is foil faced to
provide an eff ective vapour barrier and the foil also prevents fi bre migration.
