Exposure for up to 6 Months if the edges and joints are sealed with a suitable sealant. (3 months for DensGlass specifically). Nullifire 703: A fire mastic, essential for fire performance, but can also serve as a sealant for 6 months of exposure.

Exposure for up to 12 Months if the edges and joints are sealed with a suitable sealant AND Dafa sealing tape is applied over the joints.

If additional airtightness is required at the sheathing board layer, Benx recommends using the Joint Seal Kit.The Joint Seal Kit consists of Joint Seal Liquid in combination with Dafa sealing tape.
