Introducing Pavawall GF XL, an innovative render/plaster compatible insulation board designed for exterior facades. Crafted from natural and ecological woodfibre, this board is not only environmentally friendly but also boasts a high heat accumulating capacity, making it an ideal solution for protection against summer heat. Its convenient size ensures easy and quick application, perfect for both timber framework and exterior masonry facades.

Available in a range of thicknesses from 40 mm to 160 mm, Pavawall GF XL is versatile enough to meet various insulation requirements. The board’s tongue and groove edge profile contributes to a seamless installation process, while its dimensional stability under diverse conditions guarantees long-lasting performance.

Because the board is a plaster carrier it is ideal for EWI, IWI and internal roof installations.

Pavawall Key Features:

• Natural and Ecological: Made from sustainable woodfibre.
• High Heat Accumulation: Offers excellent protection against summer heat.
• Easy Application: Convenient sizes for quick installation.
• Versatile: Suitable for timber framework and masonry facades.
• Range of Thicknesses: Available from 40 mm to 160 mm to suit different needs.
• Stable: Excellent dimensional stability for enduring efficacy.

For the best results, always consult local regulations and installation guidelines, as well as the manufacturer’s recommended render systems. Store the insulation boards on a flat surface, keep them dry, and protect them from direct sunlight.

Pavawall is a testament to the commitment to providing high-quality, sustainable building materials that contribute to a greener future.

Technical Specifications:

• Edge Profile: Tongue and groove for easy installation.
• Density: Ranges from 130-165 kg/m³, providing a sturdy and reliable insulation layer.
• Thermal Conductivity: A lambda value (λd) of 0.040-0.043 W/(mK), ensuring effective thermal insulation.

**IMPORTANT** – Please note:

Wet, damaged, deformed or soiled insulation boards must not be installed. The PAVAWALL GF XL panels do not act as a rain screen during the construction phase for the ETICS work in question, they must therefore be protected from bad weather. If there is a risk of exposure to the weather, the panels must be effectively protected (e.g. by installing a rainscreen in front of the scaffolding) until the work is completed.

Panels stored on site must be protected from the elements with a tarpaulin, or a clean and tight pallet cover. PAVAWALL GF XL panels must be coated within 2 months of installation.

Thermal insulation both in summer and in winter

One advantage that is particularly noticeable in winter: thanks to the woodfibre, the home retains its comfortable warmth for a long time, because the extraordinary thermal-insulating characteristics of woodfibre materials avoid heat loss. The natural porosity and the composition of the fibres make the wood a particularly effective insulator.

Thanks to the woodfibre you can enjoy a mild temperature even on hot days. The attics in fact tend to heat up a lot in summer because the roof captures the warmth of the sun on a very large surface. Woodfibre board products have a higher weight than, for example, glass wool and can offer greater resistance to solar radiation (greater heat storage capacity). The daytime heat is then released only in the evening hours, cooler.

• Easy Installation: The material can be processed using simple cutting tools and is highly resistant to slumping, making installation quick, easy, and accurate.

Pavaflex Applications:

• Floors, Walls, and Roofs: Pavaflex is highly suitable for insulation between rafters of timber frame constructions and can be used in floors, walls, and roofs for permeable construction methods.

Carbon Locking:

Why is woodfibre insulation so good at locking carbon throughout its lifecycle:

• Trees capture CO2 from the atmosphere and store it as carbon.
• Mature trees are harvested, their carbon is captured and stored in buildings and other wood products.
• More trees are planted than felled, and the size of the European forest carbon sink continues to grow.
• Using sustainably sourced wood instead of other materials saves CO2 emissions, both through the carbon captured and stored in the wood product and the avoidance of alternative CO2 intensive materials.

The easiest way to capture carbon and reduce CO2 in the atmosphere is increasing the use of wood in construction.

Choose Pavaflex for a flexible, natural, and ecological thermal insulation solution that aligns with your commitment to sustainability and performance.
