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 PLUS+ - The world’s thinnest inverted insulation system
ProTherm Quantum is a rigid Vacuum Insulation Panel (VIP). The VIP panel consists of a compressed fumed silica sand microporous core which is evacuated of air and moisture before being encased and sealed in a special thin, gas-tight, hybrid aluminium foil envelope, encapsulated in a solvent free polyurethane waterproof coating. With a declared (aged) thermal conductivity of 0.007 W/m.K, the ProTherm Quantum® PLUS+ VIP panel provides an insulating performance that is up to five times better than other commonly available insulation materials.
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 Warrington Fire under classification report no. 19808F dated 10 10 2019. Building Regulation Approved Document B volume 1 – dwellings and volume 2 - non-dwellings compliant solution for buildings over 18m high in England.

Radmat PermaQuik – KGX1 Google HQ
Google’s new headquarters in King’s Cross, London or KGX1 is a groundbreaking project that exemplifies innovation and sustainability. Designed by Heatherwick Studio and Bjarke Ingels Group (BIG), the headquarters is often referred to as a “landscraper” due to its unique horizontal design, which stretches over 330 meters – longer than the Shard is tall. Unlike conventional skyscrapers, the building’s low-rise design reflects Google’s intent to create a workspace that is both flexible and sustainable, integrating into the local industrial character of King’s Cross.
The rooftop garden is a standout feature of the new headquarters. Spanning approximately 300 meters, the terraced garden provides green spaces for employees to relax, exercise, or work outdoors. In addition to promoting employee well-being, the garden plays a significant role in enhancing biodiversity and reducing the building’s environmental footprint. The green roof improves insulation, reduces energy consumption, and manages stormwater runoff, while also contributing to air quality and mitigating the urban heat island effect. The design of the garden, which mirrors the cascading layout of the workspaces below, seamlessly integrates the building’s outdoor and indoor environments, creating a harmonious space that connects occupants with nature.
An integral part of the roof construction is the waterproofing. Radmat’s PermaQuik Hot-Melt Waterproofing System ensured a watertight seal with a 40-year guarantee and BBA Certification for the “design life of the building on which it is incorporated.” Combined with Radmat’s Protherm G XPS X 300 SL insulation the construction team was confident that the tiered rooftop gardens, pathways, and various surfaces would be durable and leak-free. Given the 330m length is an activity roof, it was essential for it to support the planted gardens and withstand both foot traffic and weather conditions.
Thanks to its durability, flexibility, and strong adhesion, the PermaQuik waterproofing system was also applied in the underground plenums. This step was crucial to ensure the building’s foundations remained watertight. It is quite an unusual approach and quite difficult to produce so a collaborative approach was needed to maintain its integrity. The system was combined with EshaFlex 370 Reinforced Bitumen Firesafe Membranes and the ReadySeal Cold Liquid Applied Waterproofing Membrane was used to seal steel-work and pipework joints.
The reliability of Radmat’s waterproofing products will ensure the construction remains watertight for very many years to come.
