Hello,
I want to add thermal insulation cladding to my old building (built in 1899, brick construction with plaster, top layer: textured render, 250 sqm (2690 sq ft) calculated exterior wall area, detached) without removing the existing plaster.
As a base, I am using rectangular timber battens with a cross-section of 80x60 mm (3x2.4 inches). These are fixed to the plastered exterior walls as the first step. Between the wooden elements, I plan to insert Styrodur (expensive) or closed-cell polystyrene, or as a last resort compressed glass wool, so that a flat outer surface is achieved.
Now my main problem: Which cost-effective building materials are suitable (flat sheets, UV-resistant, water- and frost-proof), preferably with a detachable connection to the supporting elements?
My idea is to use HDF boards with a plastic coating, similar to laminate panels marketed for wet rooms. The main difference when used outdoors is that the temperature range varies between roughly -20°C and +60°C (-4°F and 140°F), either in shaded or sun-exposed areas (coefficient of expansion?!).
Which wall cladding would be similarly cost-effective and just as easy to install?
