DensGlass is primarily used as an exterior gypsum sheathing in building construction, serving as a foundational layer for a wide range of weather and air barrier systems. It is engineered to provide superior moisture and mold resistance, contributing to the durability and longevity of a building's envelope.
Key Functions of DensGlass Sheathing
DensGlass plays a critical role in the integrity of a building's exterior walls due to its unique composition and properties.
Substrate for Air and Water-Resistive Barriers
One of its most important functions is to act as an ideal substrate for diverse air and water-resistive barriers (WRBs). This crucial role ensures that external elements like rain and air infiltration are effectively managed, protecting the building's interior. These barriers include:
- Building wraps: Traditional house wraps applied over the sheathing.
- Fluid-applied coatings: Liquid membranes sprayed or rolled onto the surface to form a seamless barrier.
- Self-adhering membranes: Peel-and-stick membranes that adhere directly to the sheathing.
- Spray foam applications: Insulating and air-sealing foams applied to the sheathing.
Its inherent resistance to moisture and mold makes it an excellent choice for these applications, particularly in humid climates or areas prone to water exposure.
Enhanced Moisture and Mold Resistance
DensGlass sheathing features a fiberglass mat facer and a specially treated core, providing exceptional resistance to moisture absorption and mold growth. This makes it particularly valuable for:
- Exterior walls: Protecting the structural components from weather.
- Moisture-prone environments: Ideal for use in climates with high humidity or frequent rainfall.
- Preventing interior issues: Reducing the risk of mold and mildew development within wall cavities.
Fire Resistance
DensGlass is known for its non-combustible core and fiberglass mat, which contributes to the fire resistance of wall assemblies. It is often used in fire-rated wall systems, helping to meet stringent building code requirements for safety.
Durability and Dimensional Stability
The rigid nature and unique composition of DensGlass provide:
- Impact resistance: Standing up to minor impacts during construction and throughout the building's life.
- Dimensional stability: Resisting warping, buckling, or delamination, which ensures a flat and stable surface for exterior finishes.
Common Applications
DensGlass sheathing is a versatile material used in a variety of construction projects where performance, durability, and moisture resistance are paramount.
Application Area | Description |
---|---|
Commercial Buildings | Widely used in office buildings, retail spaces, and industrial facilities for its robust performance as exterior sheathing and its ability to accommodate various exterior finishes. |
Multi-Family Housing | Common in apartment complexes, condominiums, and student housing where enhanced fire, moisture, and sound performance are crucial. |
Healthcare Facilities | Preferred for hospitals and clinics due to its mold and moisture resistance, contributing to healthier indoor environments. |
Educational Institutions | Used in schools and universities to create durable and long-lasting building envelopes that can withstand heavy use and various weather conditions. |
High-Performance Buildings | Essential in structures designed for superior energy efficiency and indoor air quality, acting as a critical component of advanced air and moisture barrier systems. |
Residential Construction | Utilized in custom homes and high-end residential projects, especially in regions requiring enhanced protection against moisture, mold, or fire, or where a premium substrate for exterior cladding is desired. |
