Technical Properties of Panels ( Products )


• Thermal Performance

Rigid urethane insulation has one of the lowest thermal conductivity ratings of any insolent . This makes the retention of heat more efficient, and facilitates the effective maintenance of a temperature controlled environment such as a chill store. The matrix of the insulation core has a closed cell structure that guarantees reliable thermal performance over the lifetime of the building.

Environmental

• Strength

Rigid urethane insulation provides a high level of compression and shear strength, which are essential requirements for insulated sandwich panels.

• Ageing

Insulation panels faced with impermeable materials such as steel shows minimal change to the thermal conductivity of the insulant over the life of the installed cladding system.

• Water Absorption

The water vapors permeability of rigid urethane insulation is very low due to its closed cell structure. Permeability is further reduced by the metal skin of a panel which acts as a moisture barrier.

• Fire Performance

Like all organic building materials - wood, paper, plastics, paints - rigid urethane insulation is combustible, although its ignitability and rate of burn depend largely on the fire resistance properties of the material used to skin the panels. The most effective fire resistance can be obtained using a fire rated rigid urethane insulation. By careful blending the urethane with certain additives, it is possible to formulate rigid urethane systems that achieve the fire standards required by National Regulations and the more demanding requirements of the insurance industry.
Insulated panels with fire rated cores have performed well in actual fires and do not contribute significantly to the fire load in the building. They have an excellent track record as roof and wall cladding systems with over 40 years of history. Tests carried out in the UK, Germany, France and the USA all conclude that well designed fire rated insulated sandwich panels have excellent fire resistant properties.

• Adhesion to the Panel Skin

During the time between mixing and the achievement of its final cured state, rigid urethane insulation is extremely adhesive, which allows it to bond effectively to a wide range of insulated panel skins. The adhesion is so strong that the bond strength can be higher than the tensile or shear strength of the insulation itself.

• Weight

The light weight of rigid urethane sandwich panels is an important contribution to the achievement of lighter and cheaper building structures due to the lower dead loads. Site assembly is also faster and incurs lower cost due to ease of handling. And transport costs are kept to a minimum because of lower product volume and increased load utilization.

• Chemical Resistance

Rigid urethane insulation provides excellent resistance to attack from a wide range of chemicals, solvents, and oils.

• Biological Resistance

Rigid urethane insulation does not support fungal growth and is immune from attack by mould, mildew and vermin infestation. This is essential for hygiene applications.

• Energy Efficiency and Pay Back

The energy saving contribution of rigid urethane PIR insulation is a very positive factor. Working to this principle rigid urethane PIR insulation, with one of the lowest thermal conductivity values offers the greatest potential for energy saving.

Conclusion

Rigid urethane insulation therefore emerges as a unique material, which is perfectly suited for the insulating core of building panels. Our insulated roof and wall systems, pre-engineered in this way, provide a durable, economic, ‘fit for purpose‘ roof or wall cladding solution.
