Izocam Type 350 Roof Blanket: High-Performance and Flexible Glass Wool Insulation

Izocam Type 350 Roof Blanket is a glass wool-based, flexible insulation product designed to deliver effective thermal performance, especially in pitched roofs and metal roofing systems. With its A1 non-combustible classification, sound absorption capability, and easy installation benefits, it reduces energy loss while providing a safe and long-lasting insulation solution.

Product Description

This flexible glass wool blanket is produced by bonding molten glass fibers with special binders. It fits tightly between rafters without leaving gaps, enabling fast, efficient, and low-waste installation. It is ideal for metal roofs, sandwich panel undersides, and attic insulation applications.

Technical Specifications (Type 350)

• Thermal conductivity (λD): 0.040 W/mK (at 10°C)
• Reaction to fire: A1 (non-combustible)
• Thickness options: 80 / 100 / 120 / 140 / 160 mm
• Standard width: 1200 mm

Length (depending on thickness):

• 80 mm → 10 m
• 100 mm → 8 m
• 120–140 mm → 6 m
• 160 mm → 5 m
• Thermal resistance (RD): 2.00 / 2.50 / 3.00 / 3.50 / 4.00 m²K/W
• Water vapor diffusion resistance (μ): 1 (breathable structure)

Note: Dimensions are based on production standards and may vary depending on project requirements.

Applications

• Pitched roof and attic insulation
• Metal roof systems and sandwich panel undersides
• Horizontal applications without load
• Industrial buildings, warehouses, sports halls, and commercial structures
• Residential attic thermal insulation

Advantages

• Energy efficiency: Minimizes heat loss thanks to low thermal conductivity
• Fire safety: A1 non-combustible classification
• Flexible and lightweight: Easily fits between rafters, speeding up installation
• Acoustic performance: High sound absorption due to fibrous structure
• Vapor permeability: Helps reduce condensation risk with μ=1 breathability
• Durability: Maintains performance for many years when properly installed

Installation Recommendations

• Use personal protective equipment (gloves, mask, goggles) during installation
• Do not fully cover with impermeable materials such as plastic sheeting; vapor permeability must be maintained
• Ensure insulation continuity and avoid thermal bridges
• Do not block roof ventilation gaps

Frequently Asked Questions

1) What is the difference between Type 350 and Type 300?
Type 350 is preferred for projects requiring higher thermal resistance. Technical values and dimensions vary according to product specifications.

2) Is the product non-combustible?
Yes. It is classified as A1 and provides the highest level of fire safety performance.

3) Which thickness should be selected?
It depends on the project’s U-value target, rafter height, and roof design. Thickness ranges from 80 to 160 mm.

4) Is it vapor permeable?
Yes. With a μ value of 1, it allows vapor diffusion and helps reduce condensation risk when properly detailed.

5) Can it be walked on?
No. The product is not designed to carry load, and stepping on it is not recommended.
