The timber industry company Setra is the first business in Sweden to offer a new moisture protection for frames made from cross-laminated timber. The protection is applied directly in the production facility and simplifies the construction process.
“Having to take into account the weather and humidity is a constant issue in the construction industry, regardless of the material being used. We are very pleased to be able to offer an effective solution that makes work easier at construction sites and makes it even easier to build with wooden frames,” says Theres Jansson, CLT salesperson at Setra.
The Wetguard200SA moisture protection is manufactured by the Swiss company Siga Cover AG. It consists of an advanced membrane that allows the wooden frame to breathe and releases moisture in the vapor phase, while at the same time protecting against the penetration of water and other dirt. The protection is applied to surfaces such as floor structures and end-grain wood when the frames are being manufactured in Setra’s cross-laminated timber production facility.
“Wetguard allows construction to continue regardless of the weather, and construction companies do not have to think about using traditional weather protection such as tents, which cost both time and money to install,” says Theres Jansson.
The method has been tested by Setra, ByggPartner and Siga on a large scale during different seasons. All the measurements show that the protected wood complies with the limit values for moisture by a large margin, even when the frames have been exposed to severe weather.
Setra is one of Sweden’s largest wood industry companies. Setra processes raw material from responsibly managed forests into climate-friendly products such as glulam, planed products, components, CLT and sawn wood products.
