DensArmor Plus® Interior Panels, which feature fiberglass mats instead of the paper facings used on the surface of traditional gypsum board products, resist mold growth.  They’re ideal for areas prone to high humidity such as basements and residential bathrooms, and are ideal for commercial pre-rock installations.1 They are designed for direct attachment with screws or nails to wood and metal framing or existing surfaces. They may be used as a covering material for flat or curved structures. Dens® Solutions are industry trusted, high-performing fiberglass mat gypsum panels suitable for your wall, roof, ceiling and floor projects. Dens Solutions carry the mark of our valued heritage in Gold, as a visible standard-bearer of our position as the first manufacturer to create a fiberglass mat board and as a relentless innovator of strength and moisture resistant products for over 30 years. Dens Solutions answer building challenges with ingenuity.

1When tested as manufactured in accordance with ASTM D3273, DensArmor Plus Interior Panels have scored a 10, the highest level of performance for mold resistance under the ASTM D3273 test method, a testing method set by ASTM International, which develops testing guidelines and procedures for building materials, products, systems and services. The score of 10 in the ASTM D3273 test indicates no mold growth in a 4-week controlled laboratory test. In addition, the mold resistance of DensArmor Plus Interior Panels have been validated by UL Environment and listed in its Sustainable Product Guide utilizing microbial resistant testing based on ASTM Standard D6329-98. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting. No material can be considered mold proof. When properly used with good design, handling and construction practices, DensArmor Plus Interior Panels provide increased mold resistance compared to standard paper-faced gypsum products.
