What is DensGlass® Sheathing?
DensGlass Sheathing is a fiberglass mat gypsum panel designed to provide superior moisture and fire resistance. Its unique composition includes a moisture-resistant gypsum core encased in fiberglass mats, making it ideal for various exterior cladding systems. With its gold color, DensGlass Sheathing is easily recognizable and trusted by builders across North America.
Advantages of DensGlass® Sheathing
Moisture Resistance
One of the standout features of DensGlass Sheathing is its exceptional moisture resistance. Unlike traditional paper-faced gypsum boards, DensGlass boasts a fiberglass mat that prevents moisture absorption, making it suitable for environments with high humidity. This characteristic protects the structural integrity of buildings during and after construction.
Fire Resistance
DensGlass Sheathing also provides notable fire resistance. It is classified as non-combustible, making it an ideal substrate for fire-rated assemblies. This feature ensures enhanced safety and compliance with building codes, particularly in commercial applications.
Mold Resistance
DensGlass Sheathing panels have achieved a score of 10 under the ASTM D3273 test, the highest level of mold resistance. This makes them an excellent choice for areas prone to mold growth, ensuring healthier indoor environments.
Versatility in Applications
DensGlass Sheathing is suitable for various applications, including:
– Wall assemblies behind brick, stucco, and EIFS systems.
– Roof and ceiling applications where moisture resistance is critical.
– As a substrate for siding in both residential and commercial buildings.
Installation of DensGlass® Sheathing
Preparation
Before installation, ensure that the framing is square and level. The sheathing should be cut to size using a utility knife, and the edges should be aligned properly to avoid gaps.
