Balance of benefits

Sandwich panels with coated metal lining have been used in building industry for over 40 years. Some of the benefits of using our sandwich panels are:

Thermal insulation.

Thermal conductivity of panels with polyisocyanurate foam core is 0.022 W/mK.

Durability.

Protection against weather conditions, maintaining properties and appearance for many years. When coating is properly selected for local conditions, several years’ durability of panels may be reached without any problem.

Waterproofness.

Water, snow and damp will not get through. Perfectly finished joints ensure complete waterproofness for many years, if installation standards are followed.

Sound absorption.

Properly selected core material can give very good noise insulation parameters. They are particularly important if insulation of outside noise, reduction of industrial noise propagation to the outside of the building or noise reduction within the building is required.

Fire resistance.

Properties according to the needs. Proper type of core can ensure reaching fire resistance class up to A (mineral wool). This enables protection of escape routes and separation of fire compartments from each other.

Easy and quick installation, low construction costs.

10mm thick PUR/PIR foam panel has the same heat-transfer coefficient U as a 390 cm thick aerated concrete wall, or a 290 cm thick brick wall.

Resistance.

Roof panels can withstand the load of snow and wind depending on their thickness and climatic zone, with supports placed every 3 m. Wall panels in most cases can be used with supports span of up to 6 m. This results in real savings in terms of the supporting structure and also in the costs of the entire building.

Benefits for the natural environment.

Entire power input in the production of the material used for thermal insulation of the building pays for itself after two or three years from installation, on average. Materials used in production are recyclable. Steel can be easily reused. Waste core materials can also be recycled, while production of the panels itself is not harmful to the environment.
