Indoor Materials

The 4D project uses as few different materials as possible. It reduces the risk of mistakes and is easier to maintain.

• The materials must have low VOC emission to secure a good indoor climate and reduce the ventilation requirement.
• The materials must have long durability. The maintainance becomes easier, less costly and more sustainable.
• The materials must lead to no or low CO₂-emission  

Paint and joint filler

• as little as possible
• Without emissions which are harmful to the indoor climate

Gipsum

Gipsum is used for internal walls, fire insulation and sound insulation

• exists naturally
• waste product from combustion plants
• recyclable

Flooring in offices

Due to the natural cooling system there are no suspended ceilings. The carpets ensure good acoustics.

The carpets can either be made of renewable materials or have eco labels which ensures durability, indoor climate and enviromental sustainability.

Bamboo

Bamboo is a CO2 reducing material.

The time of growth is considerably shorter than the lifetime of the product. Bamboo can be harvested after 4-6 years
