Radmat Building Products are suppliers of high performance waterproofing materials marketed via specification assistance to architects, consulting engineers and quantity surveyors. The company is committed to providing technical support to the specifier and construction team with the elements of service that give comfort and a satisfactory waterproofing solution to meet the parameters given. Our range of products include:

Blue Roof - Attentuation Modules

A Radmat Blue Roof system offers an effective means of providing a Sustainable Drainage solution (SuDS) in inner city and urban environments, attenuating rainfall at roof level to provide controlled drainage of rainwater from the site. Suitable for zero falls flat roofs, terraces and podiums a Blue Roof can be finished with paving, ballast or a green roof system: delivering amenity and rainwater source control without having to locate storage tanks underground.

MedO Green Roofing

MedO is a green roof solution that uses established green roofing technologies in a simple and straightforward way. A variety of green roof solutions can be created - from low maintenance sedum matting and wildflower meadows, to landscaped roof gardens with lawns, shrubs and water features.

PermaQuik PQ6100 Monolithic Membrane Roofing

PermaQuik 6100 Monolithic membrane roofing system is a one part, hot applied, seamless rubberised self-healing membrane made from bitumen, natural rubbers, and a blend of polymers, further reinforced with a high tensile polyester fabric. This mix combines excellent waterproofing performance with toughness, flexibility, and strong adhesion to a variety of substrates.

ParaFlex Liquid Applied Cold Resin Membrane

ParaFlex is a fast curing, cold applied polyester resin waterproofing system. It is ’wet on wet’ between layers so it doesn’t need to be left to cure between coats. This means a faster application to give a continuous monolithic waterproof material.

EshaUniversal Single Layer Roofing Membrane

Esha is universal waterproofing and roofing membrane not only made from recycled end-of-life bitumen polyolefin products it is also 100% recyclable. A patented manufacturing method Esha is a shrink-free, fully adhered membrane that is more flexible and stronger than conventional membranes and has greater stability and durability.

EshaFlex Reinforced Bitumen Membranes

EshaFlex membranes feature Groove Technology®, a patented underside finish that ensures the heat acts only where it is needed, reducing warming of the membrane and increasing melting of the PE foil.

EshaPlan Single Ply Membranes

Single Ply Membranes for use as mechanically fastened or adhered roof waterproofing on flat or pitched roofs.  Suitable for refurbishment and new build applications.

Radmat Protherm Quantum - The world’s thinnest inverted insulation system

A global leader in the manufacture of high-performance materials, Kingspan Insulation has worked exclusively with Radmat to develop Quantum as the system choice for any inverted roof, terrace or balcony.

ProTherm Rockface A2 – Non-Combustible Upstand Insulation Board

A Non-Combustible Upstand Insulation Board used to thermally insulate and protect upstand walls in inverted flat roof systems. Classified Euroclass A2-s1,d0 to BS EN13501-1:2108 by WarringtonFire under classification report no. 19808F dated 10 10 2019.

Do you need non-combustible insulation on flat roof and balcony upstands?

December 2021

This is a question worthy of the QI TV show, and one that would definitely get Alan Davies the famous Klaxon and flashing lights because the obvious answers of yes or no would both be incorrect.

At present, based on the current wording in Approved Document B fire safety, the only clear YES answer is where the roof upstand is against habitable space ‘on a relevant building’, then you must use non-combustible insulation. Whether non-combustible insulation is required for parapet walls, rooflight kerbs, upstands etc. is not clear in Approved Document B fire safety, and is one area where it is hoped that the long-awaited response to the Ministry of Housing Communities & Local Government (MHCLG) consultation on Regulation 7 will provide clarity.

In the meantime, the major flat roofing industry Trade Associations have come together to produce a guidance document based on the understanding of the current regulations and the ‘direction of travel’ indicated by MHCLG. The guidance within the document is endorsed by the NHBC.

NFRC/LRWA/SPRA Guidance Document

This new document, published in mid-June 2021, clarifies that a combustible insulation board can be used on any flat roof upstand, but it:

cannot extend more than 150mm above the roof finish/walking surface
cannot be thicker than 60mm
cannot span across a compartment wall line
cannot be against habitable space

If any one of these requirements is not met then the insulation must be non-combustible i.e., suitable variants of FOAMGLAS or Rockwool that meet Reaction to Fire Class A1 or A2-s1, d0 to BS EN 13501-1.

The Guidance Document also highlights that all upstands on balconies (‘waterproofing’ over air rather than over heated space) are classified as part of a ‘Specified attachment’, and therefore all upstand insulation board must be non-combustible.
But how will this knowledge transfer to the real world of on-site construction, or the purchasing office? Will the installers be provided with the knowledge to understand where they can use combustible insulation and where they cannot? Will they know where the compartment wall lines are when waterproofing a roof or terrace?

Whilst you can use combustible insulation within the legal requirements of Approved Document B, wouldn’t it be simpler to standardise all your flat roof specifications so that all the upstand insulation is non-combustible? This would avoid any confusion on site, avoid any risk of error and avoid any risk of having to pay for the removal and replacement of the incorrect insulation board.

Also, don’t forget to specify the vertical insulation from deck/vcl level upwards so as to provide a fire break between the combustible insulation running across the roof and the external wall.
