YUTOO 40mm+ Tile Backer Board – Superior Thermal Performance for Roof Systems

Roof insulation is one of the most critical decisions in any building envelope. It determines energy performance, moisture control, and the long-term durability of the entire roofing assembly. When specification calls for high compressive strength and dependable thermal resistance, standard boards are not enough.

The YUTOO 40mm and Above Tile Backer Board is specifically engineered for roof insulation assemblies. With thicknesses starting at 40mm, this high-density board delivers the structural and thermal performance required for flat roofs, low-slope roofs, built-up systems, single-ply membranes, and green roof substrates.

Why 40mm and Above?

Thickness is not simply a number – it directly correlates to performance. Boards at 40mm or greater are purpose-designed for roof applications where:

• High compressive strength is needed to withstand heavy loads and regular foot traffic.

• Excellent thermal resistance (R-value) is required to meet modern energy codes.

• Moisture resistance is essential to protect the assembly from water absorption and degradation.

• Versatility is valued across multiple roofing systems and membrane types.

The YUTOO 40mm+ board meets all four requirements in a single, reliable product.

Key Performance Features

High Compressive Strength

Engineered to support heavy loads and foot traffic, the board maintains its integrity during installation and throughout the life of the roof. It resists compression, deflection, and point loading – critical for roofs that double as service areas or green spaces.

Excellent Thermal Resistance

A high R-value per inch means the board delivers effective energy efficiency without excessive thickness. This helps reduce heating and cooling demand, lowers operational costs, and supports compliance with building energy standards.

Moisture Resistant

The closed-cell structure resists water absorption, protecting the insulation layer from moisture infiltration. This is especially important for flat and low-slope roofs where ponding and prolonged water exposure are real risks.

Versatile Application

Compatible with a wide range of roofing systems, the board integrates smoothly with different membranes, substrates, and attachment methods – simplifying specification and reducing the need for multiple products.

Ideal For

Flat & Low-Slope Roofs

Provides a stable, insulated base for membranes on residential, commercial, and industrial flat roofs.

Built-Up Roofs (BUR)

Performs effectively beneath multi-layer bitumen and gravel surfacing, contributing thermal performance and compressive strength.

Single-Ply Membranes

Compatible with TPO, PVC, and EPDM systems, offering a smooth, dimensionally stable substrate for membrane attachment.

Green Roof Substrates

Supports the soil, vegetation, and drainage layers of green roof assemblies, with the compressive strength needed for saturated soil loads.

Compliance & Certification

The YUTOO 40mm+ Tile Backer Board is manufactured to meet recognised European and international standards:

• CE – EU

• UKCA – United Kingdom

• REACH Compliant

These certifications provide assurance to specifiers, contractors, and building owners that the product meets strict regulatory, safety, and environmental requirements.

Installation Notes

• Substrate preparation – Ensure the roof deck is clean, dry, and structurally sound before installation.

• Attachment – Mechanical fasteners, adhesives, or ballasted systems may be used depending on the roofing assembly.

• Membrane compatibility – Suitable for direct membrane application or as a substrate layer beneath separation sheets.

• Cutting – Standard tools can be used; boards cut cleanly for precise fitting around penetrations and edges.
