"Due to the complex nature of this project and the need to minimise roof thickness, Deck VQ® VIP panels were absolutely essential to its success. For its size, Deck VQ® has an astonishing thermal performance. When combined with its easy handling ability, Deck VQ® represents a model of insulation innovation"
Graham Hannington, Director of Essex & London Roofing
THE PROJECT
Deck-VQ® is Recticel’s pioneering response to customer demand for super-slim insulation that maximises comfort and protection in limited space. With a thermal performance core of lambda 0.006, Deck-VQ® was the ideal fit for a terrace roof on a stunning private property in Highgate, north London.
Set in one of the capital’s most desirable districts, The Water House is a beautiful house overlooking Hampstead Heath. Originally built in the 1960s, it has been significantly remodelled and upgraded and its new contemporary design includes various modern roof finishes, with a rear garden terrace ‘warm roof’ accessed via double doors from the first floor.
THE SOLUTION
Prior to building work commencing, a meeting between consultants SM Planning, contractor 800 Group and waterproofing system provider, Carlisle CM Europe, was held to discuss a major design challenge – how to achieve the roof’s required insulation U-value with minimal insulation build-up. It led to the specification of Recticel’s Deck VQ®, an innovative insulation system that optimises space and delivers an industry-leading thermal performance.
As well as offering an extremely high insulation value, Deck VQ® is an encapsulated VIP within a high-density PIR shell that eliminates the risk of puncturing – a potential hazard with non-encapsulated VIPs that could result in a significant loss of insulation value. It was perfectly suited, therefore, for The Waterhouse’s roof and its complex design that included a myriad of details such as an abutment to pitched slates, parapets, upstands/, returns, rooflights, mansafe collars, and a stepped change in level. The easy-to-apply Deck VQ® panels were installed by contractors Essex & London Roofing, with the roof completed using Carlisle’s Resitrix EPDM flat roofing membrane and Alutrix 600 vapour control barrier.
With its super-slim design and ultra-high thermal performance, Deck VQ® was the ideal solution for The Water House project. It ensured a minimal insulation build-up whilst meeting the required U-value. It means the client has been furnished with a roof that is in-keeping with their spectacularly-designed residence, and one that will uphold their interior comfort and wellbeing for many years to come.
