03, Interior Finishes

The space you'll live in every day

Healthy materials, elegant finishes and the flexibility to personalise every corner.

Interior Lining

Four interior lining options to suit your aesthetic and technical needs:

Plasterboard (Pladur)
Standard included
Laminated gypsum board with a gypsum core and two paper layers. Smooth, continuous surface for paint or finishes. Water-repellent versions (H1) for bathrooms and kitchens. Favourable fire behaviour thanks to the crystallised water in the gypsum.
Three-Ply Board
Exposed timber
Three layers of solid timber glued in alternating directions for maximum stability. Natural, warm spruce surface. High rigidity and durability. Ideal for wall and ceiling linings and integrated fixed furniture.
Fermacell
High resistance
High-density gypsum-paper fibre board. Natural gypsum + recycled paper fibres, with no synthetic binders. Ideal for wet areas (kitchens, bathrooms). Fire, impact and moisture resistance higher than conventional plasterboard.
OSB
Industrial aesthetic
Panel of oriented wood strands in cross-laid layers. Great rigidity and dimensional stability. Visible structure that lends an industrial character. Thermal and acoustic performance suited to interiors.
