Insulation: Armaflex or sheep's wool, the eternal discussion

By Jeroen Bouwer · 19 June 2026

I'm going to insulate soon and I'm in doubt. Armaflex is easy and moisture-resistant, sheep's wool breathes better. What do you recommend for a Belgian climate?

    I combined both: Armaflex against thermal bridges, sheep's wool in the cavities. No problems with condensation this year.
