CELENIT N boards are budget-friendly, Breathable boards that work internally or externally as part of a breathable wall construction system. Available in 1200 x 600mm in a thickness of 15mm for internal use or 25mm for internal and external use.

Made with mineralised fir wood wool bound with grey Portland cement, they are an effective alternative to cement board, plasterboard, rib or expanded metal lath. In addition, CELENIT N boards can significantly improve insulation at relatively low thicknesses and perform well with multiple types of render.

Featuring an open texture, lime plaster or lime render can be applied directly without the need for latex, PVA or SBR whilst retaining the breathability of the system. We advise using alkali-resistant mesh embedded in the basecoat render to minimise the potential of cracking where separate boards butt together.

In addition, CELENIT N is certified by ANAB-ICEA and natureplus for the eco-compatibility of materials and manufacturing process. CELENIT N is PEFC™ certified.

Used In Conjunction With


Internal and external use. Suitable for external walls, partitions, ceilings, and thermal bridges.

Use plastic washers when fixing. We recommended pairing Celenit N with Cornerstone Insulating Render as part of a boarded insulation application.

If for internal use, ensure Celenit N boards are placed within the room planned for installation a few days in advance so that the boards can adapt to the temperature and humidity.

Avoid sudden temperature increases just after the application of the boards.

Each project is unique, always seek professional advice before undertaking a project.
