Prefabricated and sustainable building panels. Step Code & Passive House Ready. We work with your team to produce energy-efficient and sustainable panels in our temperature-controlled facility. The status quo for building is to build under the elements, to let your site soak up the rain and wind. At TAG Panels, with the aid of advanced 3D modelling and modernised construction techniques, we can fabricate an entire building, walls, floors and roofs, inside. Ensuring maximum building air tightness and minimal water ingress. Keeping your home and investment warm, dry and energy efficient.
