Plank or wood plank ceilings are a traditional architectural feature. Unlike suspended ceilings, which use tiles or panels, this consists of wooden boards or planks that are installed horizontally or vertically across the ceiling surface.

Main features of boarded ceilings

• Most woods can be used including pine, cedar, oak, and cypress.

• The planks can be installed horizontally or vertically. Typically, horizontal installation visually widens a space whilst vertical installation creates a sense of height.

• Planks can be left unfinished, stained, painted, or whitewashed.

• Planks are typically installed using nails or screws to secure the boards to the ceiling joists or rafters.

• Tongue-and-groove or shiplap joints may be used to create a seamless fit between planks.

Advantages of boarded ceilings

• Natural insulation inherent to the wood

• Durable

• Acoustic benefits

• Warmth and character

Disadvantages of boarded ceilings

• Moisture and Humidity: prone to mould and rot – in areas with moisture or high humidity it is important to choose moisture resistant woods and finishes.

• Maintenance: require regular maintenance, including cleaning, sealing, and refreshing to preserve quality.

• Additional weight: they add additional weight to structure – it’s important that ceiling joists or rafters can adequately support the weight.

• Fire safety considerations: Regulations and requirements may require fire-retardant treatment of the boards.

• Proper installation is required to preserve the longevity of the boards.
