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 celebrates WGRD 2021

July 2021

World Green Roof Day, 6th June 2021, is an opportunity to enjoy green roofs from all over the world and to celebrate the benefits they bring to cities and towns, people and wildlife. As the World continues to deal with Coronavirus pandemic the mental health benefits of outdoor space and nature have never been so important.

Radmat are proud to be part of this great celebration and movement towards greener cities, and encourage town planners, developers, building owners and architects to incorporate green roofs in all future new build and refurbishments projects to increase the positive impact on the built environment and human health, and contribute to positive climate change.

The benefits of green roofs are many:

• Increase biodiversity and sustainability

• Co2 capture, improving air quality by producing oxygen and providing shade

• Reduce ambient air temperature, greenroofs absorb heat

• Reduce energy costs, through provide natural insulation for buildings

• Managing stormwater runoff by retaining rainwater

• Protecting and prolonging the life of your roof membrane

• Harmonises with the surrounding landscape

• Noise reduction, plant break up airborne noise

• Improving aesthetics and amenity

Follow @RadmatOfficial for projects and tips.

Thinner by design ProTherm Quantum PLUS+

April 2021

Environmental issues influence the construction industry at every stage of the building process. Government legislation and the Building Regulations have become more stringent with every update, requiring more sustainable approaches, and driving the industry to design, construct and deliver more energy-efficient buildings.

Building balconies and terraces over heated space is problematic for architects, designers and contractors: in new-build applications, stringent regulatory requirements and long-term economic viability have created greater demand for improved energy efficiency, while roofing designers and installers must strive to keep overall construction as thin as possible.

In order to meet the required U-values, the insulation will sometimes be installed both on top of and on the underside of the balcony or terrace. Not only can this be time-consuming, technically challenging and pose a condensation risk, it can also add unnecessary costs and increase the overall thickness of the construction.

There remains a huge industry demand for thinner and better performing products that will have a smaller impact on constructability and function in use. These limitations can significantly impact the ability to meet the requirements of Approved Document Part L Approved Document Part M and NHBC Chapter 7.1 when designing inverted roof constructions. Here the demand to insulate above habitable space can make it difficult for a designer to meet the backdrop of increasing thermal requirements whilst meeting the desire to maximise the glass façade and cater for a level threshold.

Inverted Roofing System market leader Radmat Building Products developed the ProTherm Quantum Inverted Roof Systems in 2014 to tackle exactly these issues, and in 2016 the BBA Certified ProTherm Quantum VIP Inverted Roof Systems; making it the first Vacuum Insulated Panel system to achieve such an accolade. Since then, ProTherm Quantum VIP has undergone continual development, resulting in the BBA Certifying ProTherm Quantum PLUS+ VIP Inverted Roof Systems in 2020.

ProTherm Quantum PLUS+ consists of a rigid Vacuum Insulated Panel (VIP) robotically coated with an elastomeric waterproof coating, creating a robust ultra-high performance insulation panel with a Design Lambda value of 0.007 W/mK, potentially reducing insulation thickness to 72mm to achieve a 0.15 W/m2K U-value, as opposed to 220mm of Extruded Polystyrene (XPS) or 240mm of Expanded Polystyrene (EPS).

ProTherm Quantum PLUS+ can dramatically reduce the thickness of inverted roofing systems without compromising thermal performance whilst still achieving level thresholds. Suitable for use in roofs, roof terraces, podiums, enclosed balconies over heated space, insulated walkways, green roofs and blue roofs ProTherm Quantum PLUS+ provides the thinnest and most robust state of the art insulation system for inverted roof construction.

Whether designing an inverted roof to achieve the lowest possible Surface Slab Level to Finished Floor Level (SSL-FFL) or rectifying unexpected slab of floor level issues, ProTherm Quantum PLUS+ provides the thinnest insulation solution for a given u-value in roof, roof terrace, podium and balconies over heated space.

To ensure every project achieves an optimal solution Radmat’s in-house Quantum Design Team provide a full service, from initial outline design and thermal calculation to pre-delivery site survey, providing a final design solution with layout drawings for sign off. This comprehensive process considers the insulation thickness requirements early in the design process, highlighting potential threshold issues and providing the most cost effective solution to meet the target U-value.
