SPECIFICATIONS
Vapor Retarder:
- Perm Rating of 0.02 to 0.03 perms: Like WMP-10, WMP-30 provides excellent vapor control, with a low perm rating that effectively limits moisture diffusion.
Reinforced Facing:
- Tri-Directional Reinforced Facing: WMP-30 features a tri-directional reinforced facing, providing superior strength and durability compared to standard reinforced facings.
Composition:
- Polypropylene and Fiberglass Reinforced Kraft (FSK): The facing comprises polypropylene, fiberglass scrim, and kraft paper, designed to offer enhanced durability and resistance to wear and tear.
Thickness:
- Typically 0.045 inches (approximately): This thickness includes multiple layers that make up the vapor retarder, contributing to its enhanced durability.
Tensile Strength:
- Very High Tensile Strength: The tri-directional reinforcement provides even greater tensile strength, making it resistant to tears and punctures during installation and use.
Fire Resistance:
- Class A/Class 1 Fire Rating: WMP-30 meets the highest fire safety standards, ensuring it performs well in situations requiring fire resistance.
WMP 30 is preferred over WMP 10 due to its enhanced puncture and tear resistance, superior vapor barrier properties, and excellent durability. This durability provides security, making it ideal for more demanding environments and ensuring excellent overall insulation performance.
For those attempting to convince you to purchase Foam Board over WMP-30, we respond that WMP-30 fiberglass facing is more competent for applications requiring enhanced moisture control and vapor resistance, such as in high-humidity areas. WMP-30’s superior vapor barrier prevents condensation and mold growth better than foam boards, which can trap moisture and degrade over time in such conditions.
WMP-30 fiberglass insulation includes a vapor retarder with moderate permeability, balancing moisture resistance and breathability. It features a reinforced kraft paper facing with a tri-directional fiberglass scrim and a polyethylene coating, providing good tear strength and durability. Suitable for general insulation applications, WMP-30 offers a clean, finished appearance and is ideal for walls, ceilings, and roof insulation where moderate moisture control is needed.
Clients choose Fiberglass WMP-30 over Foam Board for these three reasons:
1. The superior vapor control
2. It is more durable
3. It has higher fire resistance.
WMP-30 is often preferred in metal buildings for its ease of installation and cost-effectiveness. At the same time, foam board insulation may be chosen for its higher R-value and better insulation properties in some applications. However, when most weigh the cost, ease of insulation, and additional fire resistance, fiberglass WMP-30 is often the preferred choice.
“I wanted insulation with a higher fire rating, and you had it. Thank you for all your advice and assistance.”
