Through Fix - TFS1

For facades where an element of adjustment is required an Eltherington through-fix rainscreen cladding system is the best choice. Our through fix system offers an adjustable void depth and is therefore able to accommodate a range of insulation thicknesses, whilst overcoming any irregularities in the substrate.

That makes the rainscreen cladding solution ideal where the variances in quality of infill material on existing buildings dictate that fixings can only be secured at certain points across the facade, for example, at floor slabs.

Eltherington through-fix systems are designed so that the fixings are minimally visible across the facade, being masked by the shadow-lines between the panels. From a distance, this maintains the sheer, architectural appearance of the facade.
