Environmental work:

The company’s environmental policy is available on its website. Regular monitoring is carried out.

The product:

The Ecolid door is a folding door in a process laminated sandwich construction. The framework consists of aluminium profiles with steel reinforcement. The frame is filled with isocyanate and polyol that create a polyurethane insulation. Interior and exterior in hot galvanised sheet steel. Manufacturing takes place at the head office in Tråvad outside Vara. The service life of the door is estimated to be at least 25 years. The specified service life assumes that the product is used under the intended operating conditions. Heavy damage to the paint coating, which also damages the underlying galvanised layer should be repaired. Otherwise, maintenance is only required in accordance with the maintenance instructions in the user manual for the industrial door.

Environmental Performance Declaration:

The information about the product’s environmental performance is divided into a section on manufacturing and a section on use.


The use of resources:
– Power Consumption approx. 104 kWh/door.

Pollutant emissions:
– No measurable emissions occur.

Other information:
– Hazardous waste: Some waste occurs with the cleaning of polyol and isocyanate machines. This is dealt with by Stena Recycling destruction. An average of approximately 150 kg per year has accrued, compared to the 192 tonnes of raw material used in production.
– Other waste: Residual products in the form of cut-outs occur in production. They are not classified as hazardous waste, and can be disposed of without restrictions and used for ground insulation.
– Chemicals used in production: Polyol, Isocyanate, hot melt adhesive.

– Packaging is done around a frame. The frame consists of steel side end pieces with wooden feet, wooden slats as spacers and plastic sheet on the bottom of the door packaging. Tied with plastic ties and wooden slats on top of the door frame. Loose accessories are packed in cardboard boxes.

Own emissions:
– None known.

The metal can be recycled. Wood and rubber remnants can be used in energy recovery. Cellular plastic waste can be disposed of without restrictions (not compostable). Glue residues can be burned/disposed of.
