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. In practice, optimum performance will always be achieved by using the right combination of product, surface preparation and application procedures.
ProTherm Quantum® VIP Inverted Roof Insulation System provides a state of the 
art insulation solution for inverted roofs designed to be used as balconies, terraces, podiums and green roofs built over heated space. Thanks to its ultra-high thermal performance the Quantum® system can dramatically reduce the thickness of an inverted roofing system providing the solution to counter low upstands against the increasing thickness of traditional EPS & XPS products specified in order to meet more stringent thermal demands.
The Quantum Systems ®
A ProTherm Quantum® Hybrid inverted roof system is the most popular solution. Using a combination of both XPS and Quantum® an exceptional thermal outcome can normally be supplied without compromising the internal upstand and deliver the ability to maintain a level floor between both internal and external spaces.
A ProTherm Quantum® Pure inverted roof system is the thinnest solution possible where the severe lack of space calls for using just the Quantum® panel. Even in these challenging conditions this system will offer outstanding results.
Central to both systems’ outstanding thermal performance is the Quantum® Vacuum Insulated Panel (VIP). Manufactured in a UK based, state-of-the-art production facility, the world’s first BBA Certified inverted roof system (No. 16/5347), ProTherm Quantum® has been assessed in accordance with ETAG 031 and has a Declared (aged) thermal conductivity of 0.008 W/m K, up to five times better than other commonly available inverted insulation materials.
Radmat offers extensive technical support at all stages of the construction process, enabling the development of appropriate and efficient design solutions for a wide range of building projects. The company is committed to supplying first class materials, installed by an approved list of contractors and agrees designs that are both practical and cost effective. By designing and supplying every element of the inverted flat roofing systems to deliver exactly what it promises – the contractor and client achieves exceptional U-values, waterproofing integrity and long-term performance guaranteed as standard.
