What is a Vacuum Insulation Panel or VIP?
VIP is the abbreviation of Vacuum Insulation Panel. A Vacuum Insulation Panel generally comprises a microporous core material (e.g. based on fumed silica), which is introduced into a high barrier multilayer foil envelope. The envelope is then evacuated and sealed, obtaining a near vacuum inside the envelope.
Because of the microporous core and the absence of air, excellent thermal properties are obtained. For our Vacuum Insulation Panel as such (Core-VQ®) we can declare a lambda value of 0,006 W/mK, which is typically 3-5 better than traditional insulation materials.
Vacuum Insulation Panels have already been used for several decades in high demanding applications, especially when stringent requirements for thermal insulation are set (e.g. refrigerators). As the thermal insulation of buildings has become increasingly important over the last years, Vacuum Insulation Panels have been introduced in buildings to meet the high standards.

What is the difference between Deck-VQ® and a Vacuum Insulation Panel?
Deck-VQ® is an encased Vacuum Insulation Panels (VIP – see “What is a VIP?”). The main difference with the VIP as such lies in the level of protection against physical damage. The so called “naked” panel offers little protection of the high barrier envelope, whereas the Deck-VQ® concept offers a protective high density PIR layer on all sides.

Core-VQ: 
The Deck-VQ® concept provides a rigid panel and an excellent compatibility with a variety of waterproofing systems. In combination with the exceptional thermal performance, this solution is highly recommended for flat roof and terrace applications where limited space is available.
What membranes are required in flooring application when using Recticel PIR insulation boards?
For installation on a concrete slab it is recommended that a damp proof membrane is installed below the insulation and then an additional vapour control / separating layer above the insulation before the screed / floating floor finish.
For suspended floor applications such as timber joists there should be the vapour control / separating layer included again before the finish of timber or screed.
When installing Recticel PIR insulation boards on a suspended timber floor can it be put directly onto joists?
No, a suitable timber substrate should be included over the joists (minimum 18mm) before installing the insulation.
Why use Deck-VQ® vacuum insulation panels?
Deck-VQ® Vacuum Insulation Panels offer outstanding thermal performance.
Our Deck-VQ® panels achieve lambda value of 0.008W/mK with 60mm board thickness!
Needless to say that it is the perfect solution for refurbishments or new builds where space limitation is an issue.
Also see our cases to see how Deck-VQ® can even help you save money on your project by eliminating the need for radical and expensive constructional measures.
