The attachment of sun protection systems such as awnings in thermal insulation composite systems (ETICS), for example made of polystyrene, presents a particular challenge.
Conventional fastening methods can damage the insulation or provide insufficient stability. This is where hollow rods made of AKU®-DUR PVC-U come into play, enabling safe and efficient installation.
Background Information
Thermal insulation composite systems often consist of materials such as expanded polystyrene (EPS, Styrofoam) or mineral wool, which have excellent insulation properties but are not suitable for directly attaching heavy loads.
When installing awnings or other sun protection systems, it must therefore be ensured that the load is securely anchored in the supporting wall without damaging the insulation or creating thermal bridges.
Hollow rods made of AKU®-DUR PVC-U (unplasticized polyvinyl chloride) offer an innovative solution here.
They are used as spacers or reinforcement elements within the insulation layer and enable stable attachment of the brackets.
Advantages of Using AKU®-DUR PVC-U Hollow Rods
Secure Load Distribution:
- The hollow rods transfer the forces of the screw connection to the supporting wall without damaging the insulation.
- High load-bearing capacity and dimensional stability ensure secure fastening of heavy sun protection systems.
Thermal Bridge Prevention:
- Unlike metallic fastening elements, AKU®-DUR PVC-U hollow rods conduct minimal heat, reducing heat loss and condensation formation.
Simple assembly:
- The hollow rods can be easily integrated into the thermal insulation composite system.
- They are easy to process and adaptable to various insulation thicknesses.
Weather Resistance and Durability:
- AKU®-DUR PVC-U is corrosion-free, UV-resistant, and withstands weather influences, improving the durability of the fastening systems.
Cost Efficiency and Sustainability:
- By avoiding complex special fastenings and reducing heat loss, this method saves costs in the long term.
- The longer service life of the fastenings contributes to sustainability.
Conclusion
Hollow rods made of AKU®-DUR PVC-U offer a reliable and economical solution for the installation of awnings and other sun protection systems in thermal insulation composite systems.
They enable secure anchoring without compromising insulation properties, reduce thermal bridges, and ensure long-lasting attachment.
This makes them an ideal choice for modern facade constructions with ETICS.
