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.

What does BS 8579 tell us about the fire performance requirements of balconies & terr

November 2020

What does BS 8579 tell us about the fire performance requirements of balconies and terraces?

The 31st August 2020 was an important day for the external envelope industry. It was the day that BS 8579:2020 Balconies and Terraces was published. Why is this document so important you may ask? Put simply, even though it is only guidance it is being looked at as THE document that unlocks the confusion over exactly what a balcony is, providing a clarification of exactly what type of balcony is a ‘specified attachment’ within Approved Document B Regulation 7.

If you haven’t had a chance to read this important new British Standard yet the answers are;

Projecting open balconies, projecting enclosed balconies, recessed open balconies and recessed enclosed balconies are all balconies; whether thermally broken or cantilever.
Recessed open terraces, recessed enclosed terraces and access terraces are all roofs.
Terraces are roofs, but have a slightly different requirement depending on their distance from the boundary. But require a Broof(t4) fire exit route.

Not any clearer? The simple way to remember the requirements are “if it’s over air it’s a balcony”, “if it’s over heated space it’s a roof”.

KTH96R Urban regeneration of industrial wasteland at King's Cross, Borough of Camden, London, England, U.K.

So, if it’s classed as a roof on a relevant building to demonstrate compliance with the requirements of Approved Document B the installed roof system must be either tested to BS EN 13501-5 and classified as either Broof(t4), Croof(t3), Droof(t4), Eroof(t4) or Froof(t4) depending on the distance from the boundary, or have a surface finish as defined by Commission Decision 2000/553/ EC of 6 September 2000; loose laid gravel with a thickness of at least 50 mm or a mass ≥ 80 kg/m2 (minimum aggregate size 4 mm, maximum 32 mm),sand/cement screed to a thickness of at least 30 mm, or cast stone or mineral slabs of at least 40 mm thickness. However, in reality, most specifications are defaulting to a requirement of Broo(t4). But this still means you can use a BS EN 13501-1 Class E insulation board within the build-up, unless insurers require otherwise.

If it’s classed as a balcony (built over air) the entire build-up, apart from the waterproofing membrane, must be constructed of materials achieving fire performance class A1 or A2-s1,d0 to BS EN 13501-1, something called ‘non-combustible’. This includes the insulation board and surface finished, but the roof membrane which is exempt under Regulation 7(3)(g).

Radmat Fire Regulation Compliance for Roofs

January 2020

Following the Grenfell Tragedy in June 2017, and the subsequent investigations, the Governments of England and Scotland made significant changes to their respective Regulations related to fire performance. Approved Document B Volumes 1 and 2 in England, and Technical Handbook Annex 2.C and 2.F in Scotland, introduced a new category of ‘relevant buildings’ with the aim of reducing the fire risk in high rise buildings (those over 18m in England and over 11m in Scotland).

Whilst generally clear with regards to the fire performance requirements for external wall construction (external wall systems on buildings over 18m high have to be fire resistant, achieving class than A2-s1, d0 or Class A1 under the European classification system set out in the standard BS EN 13501-1, subject to exemptions) the regulation changes have resulted in some confusion with regards to the fire performance requirements for roofing systems, and the definitions of ‘specified attachments’, insulated balconies, roof terraces and podiums.

With the entire UK Government in Purdah (the period leading up to an election, during which government departments generally refrain from making any new announcements) the Ministry of Housing, Communities and Local Government (MHCLG) are unable to make further clarifications, however what is clear is that:

Roofing systems must achieve Broof(t4) European classification in accordance with BS EN 13501-5.
Roof finishes covered under the Annex of Commission Decision 2000/553/EC are considered to be unrestricted under the national Requirements (Loose laid gravel with a thickness of at least 50 mm or a mass ≥ 80 kg/m2, Sand/cement screed to a thickness of at least 30 mm or Cast stone or mineral slabs of at least 40 mm thickness).
Any decoration or other finish applied to any external (but not internal) surface forming part of the wall must achieve class a minimum A2-s1, d0 classification to BS EN 13501-1.

This latter requirement means that any insulation board used as part of the roofing system where it abuts an external wall must be non-combustible, effectively banning the use of PIR, XPS and EPS insulation boards between the vertical waterproofing and the external wall.

In warm roof applications it is easy to switch the vertical upstand board in this application to mineral wool or cellular glass, but with no suitable product available for inverted roof applications specialist roofing system manufacturer Radmat Building Products had to develop a suitable solution quickly.

ProTherm RockFace A2, a non-combustible upstand insulation board for inverted roof applications, consists of a special mineral wool insulation board factory laminated to a 6mm Cement Particle board. This combination, tested by WarringtonFire to BSEN1350–1, achieved an A2-s1, d0 rating. Radmat Building Products believe that this is currently the only inverted roof upstand insulation board available that meets the requirements for ‘Relevant Buildings’ within Approved Document B, and the Scottish Technical Handbooks (those over 18 m in England and over 11m in Scotland).

For further information on RockFace A2, a copy of the WarringtonFire classification report no. 19808F dated 10 10 2019, or to find out about Radmat’s range of Regulatory compliant roofing systems go to www.radmat.com or call 01858 410372.
