Precast Thermal Wall

The wall with integrated formwork and insulation

Precast Thermal Wall is a precast wall with integrated formwork made up of two fine reinforced concrete panels that are connected to each other and held apart by a system of connectors (composite connectors and load-bearing anchors), providing external wall insulation and a central space into which ready-mix concrete can be cast.

This made-to-order structural product is delivered just in time to your work sites, with all the reservations required.
