Pitched roofs / attic ceilings / partitions / frame floors

Holcim, a leader in innovative and sustainable building solutions, manufactures stone wool boards for insulating pitched roofs, attic ceilings, interior partitions, and floors in frame structures. Our products provide high thermal and acoustic comfort, and – thanks to their low thermal conductivity - effectively reduce energy loss regardless of the season. Holcim stone wool perfectly fills the spaces between rafters, joists, and profiles, while maintaining dimensional stability and not settling over time. Its resistance to fire (class A1) increases the safety of building users, and its high vapor permeability allows partitions to “breathe,” reducing the risk of water vapor condensation. It is a reliable solution for insulating lightweight structures and wooden constructions, especially where durability, effectiveness, and comfort of everyday use for generations are important.
