Hello,
I want to insulate my old building (year of construction: 1899, brick building with plaster, top layer: textured plaster, 250 sqm calculated exterior wall area, freestanding) with a thermal insulation cladding without removing the existing plaster.
As a base, I am using rectangular squared timber with a cross-section of 80x60. These are anchored to the plastered exterior walls in the first step. Between the wooden elements, Styrodur (expensive) or closed-cell Styrofoam or, as a last resort, compressed glass wool should be inserted so that a flat exterior surface is created.
Now my actual problem: Which cost-effective building materials are suitable (flat material, UV-resistant, water- and frost-resistant) preferably with a detachable connection to the support elements.
My idea is to use HDF boards with a plastic coating, as they are also sold as laminate for wet rooms. The main difference to indoor use is that the temperature range outdoors, whether shaded or sun-exposed, fluctuates between -20 degrees and +60 degrees (coefficient of expansion?!).
Which wall cladding would be similarly cost-effective and just as easy to install?
