Heco Roof screws -TOPIX® plus THERM HD-40

Ideal for rafter insulation with flexible insulating materials.

The HECO-TOPIX-plus Therm is specifically designed for the processing of flexible insulating materials. With its two threads, it allows for a distance screw connection, where the underhead thread secures the counter batten. Forces acting on it, such as wind suction and pressure loads, are exclusively transferred through the thread from the counter batten and directed into the rafter. This prevents the counter batten from being pressed into the insulation material. Compared to conventional fastening options, the HECO-TOPIX-plus Therm offers advantages in processing and material usage. In combination with the HECO-TOPIX-plus CombiConnect, it forms another system for efficient facade and roof insulation. In this system, the occurring shear forces are absorbed using a shear wood in conjunction with the HECO-TOPIX-plus CombiConnect. This system also requires significantly fewer fastening points than conventional solutions.

Product advantages: Pressure forces are directly transferred into the rafter through the underhead thread. Increased load capacity due to the underhead thread. Countersunk head with milling pockets. Usable for common insulation materials. The HECO-TOPIX tip eliminates the need for pre-drilling, reduces the risk of wood splitting, and allows for tight edge and axis distances. PerfectPitch: Optimal thread pitch for every screw length. Perfect performance for all wood applications. Design verification available through HECO design software HCS or design service. Significantly fewer screws required compared to conventional systems. Approved and monitored product. European Technical Assessment: ETA-19/0553.

Note: The HECO-TOPIX-THERM-plus, in combination with the HECO-TOPIX-CC, forms a perfect system for efficient facade and roof insulation.
