Low Lambda Excellent Thermal Insulation PUR Board 40 mm Foil Faced Panel
Excellent thermal insulation is worth most where construction depth is fixed. A 40 mm PUR board with a conductivity of 0.023 W/(m.K) gives roughly the same resistance as sixty millimetres of ordinary foam, so a refurbishment can keep its original wall line and still meet the energy target. The aluminium foil facing adds a low emissivity surface that lifts the performance of the whole build up.
The foil is bonded while the foam is still reacting, so there is no trapped air layer and no risk of facing delamination later. Excellent thermal insulation depends on that bond as much as on the foam chemistry, because a loose facing creates a convection path along the panel. Each board is checked for flatness before packing.
Specifiers working to tight U values receive measured conductivity at several mean temperatures, so the calculation reflects real service conditions rather than a single headline number. Excellent thermal insulation data, density and fire test reports travel with every shipment, and third party witnessed testing can be arranged for large projects.
Key Advantages
- Conductivity of 0.023 W/(m.K) gives high R value in a thin build up
- Aluminium foil facing adds reflectivity and protects the foam
- Foil bonded during foaming, so no delamination at cut edges
- Excellent thermal insulation verified at several mean temperatures
- Light panel weight reduces fixing count on walls and ceilings
- Tight thickness tolerance keeps insulation continuous

Frequently Asked Questions
Q: Does the thermal performance change over time?
A: Aging is slow in closed cell PUR. Our declared value retains at least ninety percent of initial performance over twenty five years.
Q: Can the foil faced board go behind render?
A: Behind cementitious render we recommend a mineral coated facing, and reserve foil facing for cavities and dry lining.
Q: What thickness gives the same U value as mineral wool?
A: As a rule of thumb, forty millimetres of this board matches about eighty to ninety millimetres of mineral wool.
Q: Do you supply samples before ordering?
A: Yes, we send cut samples with the datasheet so your team can check facing, density and thickness before the first container.
MYREAL supplies excellent thermal insulation PUR boards from Shanghai to projects in Europe, the Middle East and Southeast Asia. Contact our technical team for datasheets, samples and container plans.
