PIR flat roof insulation & fleece-reinforced PURelastik liquid plastic

The combination of PIR flat roof insulation and fleece-reinforced PURelastik liquid plastic offers a long-lasting flat roof restoration through low installation heights and seamless waterproofing. While PIR boards provide excellent insulation values (thermal conductivity Lambda value (λ) of 0.022 W/(mK)) at minimal thickness, the liquid-applied PURelastik with fleece reinforcement ensures a crack-bridging, UV-resistant, and homogeneous surface, especially at complex details.

The restoration process includes substrate preparation, installation of the vapor barrier, precise PIR placement, and full-surface sealing with PURelastik liquid plastic & fleece. This system solution guarantees compliance with GEG (future GMG) standards, high compressive strength, and a low-maintenance, durable roof structure.

Key advantages of
PIR flat roof insulation:

Low build-up height: Thanks to a thermal conductivity (λ) of 0.022 to 0.026 W/(mK), PIR boards can be up to 40% thinner than polystyrene (EPS) or rock wool while providing the same insulation performance.

High compressive strength: The boards are highly stable, making them ideal for accessible flat roofs or roof terraces.

Heat resistance: PIR can briefly withstand high temperatures (e.g., during the torch-on application of bitumen membranes) of up to 250 °C.

Moisture resistant: The material absorbs almost no water and is resistant to rot.

After substrate preparation: Installation of the PIRflat roof insulation

PIR insulation boards professionally laid in a staggered pattern: Seamless flat roof insulation without cross joints on a prepared, level substrate.

Professional installation of PIR rigid foam insulation boards (polyisocyanurate) on the prepared, level, and clean substrate. The boards are installed in a staggered pattern to avoid cross joints, with tightly butted edges to ensure gap-free thermal insulation.

Bonding and mechanical fastening of the
PIR insulation boards

Combined fixing of PIR insulation: System-compliant bonded and additionally mechanically fastened PIR insulation boards on bitumen flat roofs.

Secure fixation of high-performance PIR insulation using a combined fastening method: The boards are bonded in a system-compliant manner for temporary fixation and to prevent airflow underneath, then mechanically screw-fastened according to structural requirements.

Fully insulated flat roof with PIR flat roof insulation

Hocheffizientes Flachdach-Dämmpaket: Fertig verlegte PIR-Dämmung mit WLS 022 als druckfeste Basis für die abschließende Abdichtung.

Creation of a high-efficiency flat roof insulation package using high-performance PIR insulation materials. Thanks to its extremely low thermal conductivity (WLS 022), the completed system offers maximum energy efficiency with minimal installation height. The result is a compression-resistant, dimensionally stable, and thermal-bridge-free insulation layer that forms the perfect foundation for the final waterproofing layer.

Beginning the seamless waterproofing with PURelastik liquid plastic & fleece

Embedding the reinforcement fleece into the first layer of PURelastik liquid plastic on PIR insulation to create a seamless waterproofing membrane.

Initiating the permanently elastic surface sealing within the system structure: The first layer of PURelastik liquid plastic is applied to the prepared PIR insulation. A special reinforcement fleece is then embedded across the entire surface, ensuring it is free of wrinkles. By subsequently saturating the fleece with an additional layer of PURelastik, a seamless, crack-bridging membrane is created.

PIR flat roof insulation and seamless PURelastik waterproofing

Saniertes Flachdachsystem: Kombination aus PIR-Dämmung und witterungsbeständiger Flüssigkunststoff-Membran für maximale Energieeffizienz.

Successful completion of the energy-efficient roof restoration through the combination of high-efficiency PIR insulation and a full-surface liquid plastic waterproofing. The restored roof system now combines maximum thermal insulation with a permanently weather-resistant protective layer.

Completion of the roof restoration:

By using slim PIR insulation boards, the building's U-value was massively optimized, while the final fleece-reinforced PURelastik coating creates a jointless surface. The restoration provides long-term security, prevents energy loss, and ensures a low-maintenance, permanently waterproof roof structure through the seamless application process.
