DensGlass® Shaftliner fiberglass mat gypsum liner panels are ideal for use in vertical and horizontal shaftwall assemblies, stairwell applications and area separation walls in commercial and multi-family construction.
In buildings around the world, Georgia-Pacific’s lightweight, maintenance-free gypsum shaftwall/stairwell enclosures serve as the perfect alternative for heavy masonry construction in building cores.
Non-combustible DensGlass® Shaftliner Panels, utilizing fibreglass mats have a Euroclass reaction to fire A1 classification and offer superior mould and moisture resistance (H1 rating), are used to line the shaftwall/stairwell enclosures.
DensGlass® Shaftliner shaftwall/stairwell assemblies save space, offer quick and simple installation and don’t delay construction during cold weather. The moisture resistance properties of the DensGlass® Shaftliner Panel make it suitable for installation in semi-exposed areas before the building envelope is wind and weather-tight and is backed with a limited warranty against delamination and deterioration for up to 12 months of exposure to normal weather conditions.
Space-saving DensGlass® Shaftliner shaftwall/stairwell enclosures are designed for elevator and air shafts, stairwells and mechanical rooms in industrial buildings where greater wall heights are common and as firewalls between office, warehouse and manufacturing areas. They are also used as horizontal membranes for corridor and stairway ceilings and under mechanical equipment where fire ratings are required and normal suspension support may be difficult.
Shaftwall assemblies are built from one side only, so there’s no need to access the inside of the shaft. The strong, C-T, C-H or I steel framing goes up quickly. Most configurations require only two steel components and two types of gypsum board. That makes these systems ideal for furred chases and interior partitions where fire ratings are required for exterior walls and access is restricted. Engineered for durability, these systems withstand air-pressure surges of high-speed elevators as well as lateral impact of stairway doors.
