Deck-VQ® Vacuum Insulation Panel project in Saint-Idesbald, Belgium

The terraces of the 'Residence Bellevue' apartment building in Saint-Idesbald have been renovated and permanently insulated with the new Deck-VQ® vacuum insulation panels from Recticel Insulation.

"For this project in Saint-Idesbald we installed Deck-VQ® vacuum insulation panels from Recticel Insulation, delivered via Defrancq. With a heat conductivity rate (lambda) of 0.006 W / mK in the core (VIP) - the best performance on the market - and a limited thickness of 45 mm, it was possible to achieve a RD value of 5.00 m²K / W. In addition, the solution offers excellent protection of the vacuum insulation panel (VIP) by means of high-density PIR plates, which offers an additional protection during installation."

"The panels are available in various standard dimensions, with which Recticel drew a customised laying plan for us. The Deck-VQ® panels can be processed like a standard PIR insulation board. They can be easily glued to the surface with a PU adhesive foam. Most roof seals (plastic or bitumen overlaying) can be applied to the panels. Thanks to the panel’s encapsulated structure, the fragile vacuum insulation is safely protected and damage during installation is effectively ruled out."

The challenge: limited space

Many apartments on the Belgian coast are not yet sufficiently insulated. The problem of very limited space for insulation arises especially for the renovation and insulation of roof terraces.

Our solution where the space for insulation is limited

The innovative ultra-thin Deck-VQ® VIP panels are the solution for insulating flat roofs and terraces where space for insulation is limited. Recticel Insulation always makes a customised installation plan to ensure an easy fitting. Deck-VQ® insulation panels are available in 4 sizes for this purpose. The VIP panel delivers high performance, is extremely reliable and offers a solution where traditional insulation options fall short. The ultra-thin panels are a fast and cost-efficient solution because no structural adjustments are required when renovating terraces and flat roofs.

Deck VQ Case Study

The result is a first-class insulation that offers you many advantages in the implementation of various roof details, such as entrance door to the terrace. The panels are available in two thicknesses: 45 mm with a VIP core of 25 mm and 60 mm with VIP core of 40 mm. This VIP core has a thermal conductivity rate of 0.006 W / mK, the lowest on the market. The panels are also protected against damage, making them easy to transport and handle. Even with complex customisation, fitting is easy, thanks to the technical guidance and installation plan prepared by Recticel.
