Raw material and production

Generally, the environmental impact of a sealant’s raw materials are negligible compared to the total consumption of construction material for an entire building. Nevertheless sustainability is one of the main drivers of all R&D efforts within Sika to reduce the environmental footprint of raw materials.

Sika’s most modern production facilities have been built to fulfil the highest environmental standards and to use as few energy and to produce as few waste as possible.

Application

Air quality and low waste solutions: Sika provides Volatile Organic Compound free (VOC-free) sealants with very low emissions (e.g. EC1 PLUS certified), which ensure a safe working environment for the applicators and avoid any air pollution. Intelligent packaging with foil packs reduces waste.

Secondly, Sika focuses strongly on 1-component sealants even for applications where traditionally 2-part products have been used. These 1-component products do not need mixing, thus avoid the use of solvents for cleaning mixing equipment and tools which would be necessary in the case of 2-component products.

Use and maintenance

Saving energy: Sika’s long lasting sealing systems save energy by tight joints in the building envelope, reducing heat or cool air loss through air permeable connections between different building parts and also protecting the construction from water ingress. Innovative bonding solutions for window manufacturing enable to increase the size of glass and reduce the dimensions of sash frames. Resulting higher solar gains ultimately save heating energy. Larger glass surfaces additionally allow more daylight to enter the building, thus reducing the need for artificial lighting.

End of life

Disposal: Sika sealants do not contain any hazardous substances and can be disposed with usual waste without any danger of environmental contamination.
