Pitched roof
Are Recticel Insulation products suitable for use in inverted roofs?
No, they should be installed below the waterproofing membrane.
Sustainability & circularity
Are Recticel Insulation's products environmentally friendly?
Our boards are an extremely efficient form of insulation and over the life of a building will save far more energy in their use than required in their production, resulting in significant reductions in energy consumption and cost, as well as reduced CO2 emissions.
Construction law & regulations
Can a breather membrane be laid directly over Recticel's insulation boards?
Different breather membrane manufacturers have different guidelines for their products, and these should always be consulted prior to installation. It may be possible to lay the breather membrane on the insulation, but with a counter batten airspace above.
If you would like to discuss application of any specific project, please contact our Technical Services.
Can I recess cables into Recticel PIR insulation boards?
Cables should not be recessed into the insulation boards. They may be laid between two layers of boards with the cabling oversized to accommodate for an increase in operating temperature. If cables penetrate an insulation layer, PIR will have no detrimental effect on cable sheathing.
Further guidance on the above should be obtained from a qualified electrician.
How thick do I need to insulate?
We recommend that you seek advice from your architect, designer, energy assessor etc. to determine the appropriate insulation thickness. If you already know the desired performance, you can contact our Technical Services team for U-value calculations or look up the required R-value and corresponding thickness in the technical datasheet.
The cleanest energy for heating and cooling, is the energy you do not have to use. That is why we recommend to insulate a flat roof to a higher standard than the minimum requirement. We recommend a minimum of 45 mm Deck-VQ® (Lambda (λ) = 0,009 W/mK) for renovation and 60 mm (Lambda (λ) = 0,008 W/mK) for new build.

What are the main tips for installing Recticel Insulation boards correctly?
- Use the right board for the application - the right type and the right format.
- Store the boards in a dry place above the ground, and use them when they are dry.
- Handle boards carefully - do not throw or kick them, be careful not to damage them.
- Ensure the intended substrate/base is clean, even, dry and smooth.
- Apply an air screen, sealing layer or damp resistant layer if necessary, particularly in flat roofs.
- Push boards together well.
- Always keep boards dry during rain showers.
- Always cover boards at the end of the working day.
- Always follow installation instructions provided.
- Always use the right attachment methods.
- Measure and cut accurately to fit using a fine toothed saw or sharp knife
-
Ensure that any adhesive is compatible with the foam
Energy efficiency
Can electric cables be channelled into Recticel insulation boards?
No, as this would reduce the performance of the boards. Cables can penetrate the insulation with no detriment to the cable sheathing. Any cables penetrating or lying against insulation should be oversized to cater for increased operating temperature. If in doubt, consult a qualified electrician.
Moisture & condensation
Is Eurothane PL available with a vapour control layer?
Recticel Insulation's Eurothane® PL is a versatile product that can be fixed either mechanically or with gypsum adhesive, in accordance with installation guidelines. It has a built-in vapour control layer as standard, located between the PIR core and the plasterboard.
Vacuum 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.
