What Is a Water- and Moisture-Resistant Building Board?

Cement- and fibre-based building boards are used where standard gypsum board is not made for lasting contact with water: facade cladding, semi-open areas such as pergolas and balconies, wet rooms, and partitions in damp areas. The board is screwed to a supporting frame; joints, edges and water-stop details are solved separately.

The Products We Have Used

  • BoardeX® — orange-faced exterior board. We used it on facade cladding and a pergola.
  • Knauf GUARDEx® — blue-faced board. We used it on a partition wall.

Each product's field of use and its limits follow the manufacturer's own technical document. We do not publish performance figures we have not verified.

Where It Is Used

  • Facades and semi-open areas
  • Wet-room walls and tile substrates
  • Partitions in damp areas
  • Wall surfaces carrying plumbing

What We Offer

Facade Cladding

Board on a supporting frame; joints closed with a flexible filler.

Wet-Room Wall

Board as the substrate behind tile in showers and bathrooms.

Partition in Damp Areas

Water-Stop Detail

FAQ

Frequently Asked Questions About Water- and Moisture-Resistant Building Boards

We have compiled the topics our clients are most curious about

How do these boards differ from gypsum board?

Standard gypsum board is not made for lasting contact with water. Cement- and fibre-based boards stand up to wetting better; each product's limit is stated in its own technical document.

Isn't moisture-resistant (green) board enough?

Green board is for splash zones. For surfaces in lasting contact with water, and on facades, we use cement-based board.

Which brand do you use?

It depends on the project. In our own work we have used BoardeX and Knauf GUARDEx; the brand and model chosen is written into the quote.

What goes on top of the board?

On a facade, the cladding system of that manufacturer; in a wet room, waterproofing and tile. We do not mix system components from different manufacturers.

What does the warranty cover?

Workmanship within the scope stated in the written quote carries a 1-year warranty. Boards and components follow the manufacturer's own warranty terms.

Can you carry out the work while I am abroad?

Yes. We agree the scope in writing before starting, send dated progress photographs at each stage, and can hold a video call on site whenever you want to see something specific. Keys are handed over against a written record, and the flat is cleaned and photographed again at handover.

How is the scope agreed and what does the written quote contain?

After the survey you receive a written scope listing the rooms and areas covered, the system chosen for each, the brand and product of the boards, profiles and insulation, the surface finish level, and the number of working days. Anything not on that list is not in the price, which is what stops the mid-project additions that make contractor quotes unreliable. Nothing is charged beyond the written scope without your approval.

How long before the property is usable or ready to let?

Ceilings and partitions leave the space usable as soon as the crew finishes. Painting needs longer: the film cures over roughly a week, and the smell in a ventilated flat clears within two to three days. If a flat is being prepared for tenants, plan on a few extra days after handover for airing and cleaning rather than scheduling a viewing for the day of completion.
