Material
Panespol Panels are a composite board with a rigid Polyurethane body and special fire resistant Acrylic surface.
Fire Resistance
Panespol Panels conform to UK Building Regulations Approved Document B (Fire Safety) for use in all domestic and most commercial applications.
Panespol Panels are fire tested to European Classification Class C & D (equivalent to British Standard 476 Classes 1 & 3) as required by UK Building Regulations.
Heat Resistance
Panespol Panels will not melt and will not catch fire, but their physical stability can be affected by extreme direct heat.
THEY CANNOT BE USED INSIDE FIREPLACE OPENINGS.

Thermal Resistance
A typical 25mm thick Panespol Panel has a Thermal Resistance (R value) of 0.56 m² K/W. This equates to an excellent Thermal Conductivity value of less than 0.045 W/mK.
The table below compares the low thermal conductivity of Panespol with some other common building materials. Whilst this clearly illustrates the superior insulating properties of Panespol, it really tells only half the story. Laboratory tests are carried out in still air conditions, a situation rarely found in the real world. Since rigid Polyurethane, the material used to produce Panespol, is an air barrier as well as an insulator, then with wind movements and thermal air currents taken into consideration the true comparison of Polyurethane against a mineral wool or glass fibre insulation is more like 5:1 in favour of Polyurethane. The insulation properties of materials are also adversley affected by moisture absorption and as Panespol does not absorb water, this again adds to it's already excellent insulating capabilities.
Remember - The lower the value, the better the insulator
