HECO-TOPIX®-plus-T Solar The cost-effective fixing for solar panels onto roof trusses

HECO-TOPIX^®-plus-T Solar

The innovative screw for solar panels on over-rafter-insulated roofs.

The securing of solar panel roof bracket onto timber roofs where insulating material is fixed below requires innovative fixings. As low-strength insulating materials cannot withstand compressive loads, such as the additional weight of the solar panel, roof tiles or snow loads. Even when using pressure resistant insulating material it is always necessary to offset the additional compressive load i.e. to transfer the load through the counter batten and insulating material into the rafters.

With this in mind the new HECO-TOPIX®-plus-T Solar in stainless steel with its innovative under head thread is the ideal solution. The thread enables a secure fixing by means of screws secured at defined intervals. The under head thread of the HECO-TOPIX®-plus-T Solar prevents the compressive forces from pressing on the insulating material, instead of transmitting them via the screw into the rafters. Additional shear loads can also be transmitted using partially threaded screws (angle of screw to roof pitch = 60°). The tried and tested HECO-TOPIX®-plus point also prevents any risk of the counter batten splitting.

HECO-TOPIX®-plus Flange head screw, stainless steel

 The HECO-TOPIX®-plus Flange head in stainless steel is an ideal fixing solution for securing solar panel roof bracket onto timber substructures.

There is no need to pre-drill with TOPIX® in most hardwoods, which makes the application quick and easy and combines all the best features for a safe, secure and user friendly fixing. The TOPIX® point prevents any risk of the counter batten splitting. In addition, the HECO-TOPIX®-plus Flange head in stainless steel also has German national technical approval. Made in A2 Stainless steel makes this ideal for outdoor use which provides ultimate corrosion resistance and fastening, and is therefore as durable as the solar panel themselve.
