A: Wood and wood-based materials with indoor air relevance
Wood and wood-based materials installed on the room side of the airtight layer of the building.

B: Wood and wood-based materials without interior air relevance
Wood and wood-based materials that are not installed on the room side of the airtightness layer of the building.

	The criteria is relevant and the product supports the fulfillment of the criterion.
	The criterion is relevant, but it must be demonstrated on a case-by-case basis for the products supplied in the respective construction project.
	The criteria is not relevant for the application.

	if an application is displayed in green, all relevant criteria of this application are met.
	If at least one of the relevant criteria for an application is not met, the application is displayed in red.
