Celit

Every house deserves a Celit underlay or insulation protection board

Thanks to their superior quality, Celit wood fiber boards are the leading choice for underlays and wall protection for exterior walls. Made in Norway with sustainable, PEFC-certified wood fiber and infused with Belgian expertise, our Celit wood fiber boards protect your building maximally against wind, (driving) rain, snow, and moisture. Celit also improves your insulation, prevents thermal bridges, and dampens noise from outside.

Contractors appreciate the sturdiness and easy installation, while fans trust the long lifespan of at least 60 years. With Celit, you choose not only quality but also long-term peace of mind.
