When it comes to exterior wall protection in commercial and residential construction, GlasRoc (GlassRoc) glass mat sheathing by Georgia-Pacific offers superior performance over traditional wood-based products. Dil Chahal Construction installs GlasRoc sheathing throughout Saskatoon, SK, providing your building's exterior walls with non-combustible, moisture-resistant, and mold-resistant protection during construction and throughout the life of the building.
GlasRoc's performance characteristics make it the preferred exterior sheathing for commercial buildings, multi-family residential, and any high-performance construction where fire-rated wall assemblies are specified. Our experienced team installs it correctly — fastened to the required pattern, properly sealed at joints, and integrated with weather resistive barriers — ensuring the assembly performs as engineered and passes all required inspections in Saskatchewan.
Why GlassRoc Outperforms Traditional Sheathing
Fire Resistant
GlasRoc is classified as non-combustible — a critical advantage in fire-rated exterior wall assemblies for commercial, multi-family, and code-specified residential projects in Saskatoon.
Moisture Resistant
The glass mat face resists moisture intrusion during the construction phase and throughout the service life of the wall assembly — important in Saskatchewan's wet seasons and freeze-thaw cycles.
Mold Resistant
GlasRoc's inorganic glass mat and core do not support mold growth under normal conditions, preventing the air quality and structural issues associated with mold in wall assemblies.
Durable Performance
Unlike wood sheathing, GlasRoc doesn't swell, warp, or delaminate when exposed to moisture — maintaining dimensional stability and consistent performance across Saskatoon's demanding climate.
Our Process
Assembly Review & Planning
We review the wall assembly specifications, confirm fastening patterns, and plan the installation to ensure GlasRoc performs correctly within the overall exterior wall system.
Framing Inspection
Before installation, framing is checked for proper alignment, plumb, and spacing — correct framing is essential for GlasRoc to fasten securely and the wall to perform as specified.
Sheathing Installation
GlasRoc panels are installed vertically or horizontally as specified, fastened at the required on-centre spacing using the correct fastener type and pattern for the assembly.
Joint Sealing & WRB Integration
Panel joints are taped using GlasRoc-approved joint tape, and the sheathing is integrated with the weather resistive barrier (WRB) system to maintain a continuous drainage plane.
Inspection Ready
Completed installation is reviewed against the assembly specifications and documented for the building inspector — ensuring the exterior envelope passes scrutiny before cladding is applied.

Frequently Asked Questions
What is GlassRoc sheathing and where is it used?
GlasRoc is a glass mat exterior gypsum sheathing product that is non-combustible, moisture-resistant, and mold-resistant. It's used on exterior wall and roof assemblies in commercial buildings, multi-family residential, and high-performance homes in Saskatoon, SK where traditional wood-based sheathing isn't suitable.
What are the fire resistance properties of GlassRoc?
GlasRoc is non-combustible and contributes to fire-rated wall assemblies specified in Saskatchewan's commercial and multi-family building code requirements — a key advantage over wood-based sheathing.
Is GlassRoc suitable for Saskatoon's climate?
Yes. GlasRoc is designed for moisture exposure during construction and long-term performance in assemblies subjected to Saskatchewan's freeze-thaw cycles, extreme temperature swings, and seasonal precipitation.
Can GlassRoc replace OSB or plywood?
GlasRoc is a non-structural exterior gypsum sheathing layer — not a structural substitute for OSB in shear walls. However, it's commonly used as the exterior face sheathing layer in commercial and multi-family wall assemblies. We advise on the correct assembly for your Saskatoon project.
