We renovate a mansard terraced house from the 1900s. Should we make an interior insulation of the walls, if so with what type of plasterboard and what glass wool. We are currently installing a condensing boiler for heating.
The clinker is a combustion residue from coal and coke agglomerated and converted into cinderblock. This product was commonly used in the 1960s in the north of France, and in the mining regions.
This material is a poor insulator. You must absolutely isolate it, from the inside or the outside, before even considering replacing your boiler. From the inside, you will make a metal frame by placing the ceiling and wall mounting rails that will contain mineral or vegetable wool insulation and cover it with BA13 plates. Refer to our sheet on interior wall insulation.
