Gypsum vs SmartBoard ceilings compared: which suits your home?

How to choose a ceiling that fits how you'll use the space

When building or renovating, one thing many people overlook but that matters a lot is the ceiling. Besides hiding wiring and pipes, it adds to the look and helps keep heat out. The two most popular materials in Thailand are gypsum board and SmartBoard (fibre-cement board) , which have completely different properties and uses.

Gypsum ceilings: smooth and seamless, ideal for interiors

Gypsum board's main strength is its smooth finish — joints can be plastered so seamlessly that you can't see them. It's easy to cut, lightweight, insulates against heat and reduces echo well. It suits interior spaces such as bedrooms, living rooms or offices. However, ordinary gypsum's weakness is that it can't handle water or humidity — if the roof leaks, the board will go soft and grow black mould easily.

SmartBoard ceilings: strong, weather-resistant, ideal for exteriors

SmartBoard, or fibre-cement board, is made of cement mixed with natural fibres. Its main strengths are strength and excellent resistance to water and humidity , and termites don't eat it. It's ideal for exterior ceilings such as eaves soffits, entrances or areas that may catch rain spray. The downsides are that it's heavier, and it's hard to get the joints as smooth as gypsum.

Checklist to help you decide: which ceiling to choose?

To match the material to the use as closely as possible, check against these suggestions:

• Choose gypsum: for interior ceilings where looks and a smooth finish matter, and that aren't in very humid areas
• Choose SmartBoard: for exterior eaves soffits, ceilings under the roof, or very humid areas
• Consider the weight and the framing: SmartBoard is heavier, so it needs a stronger, more closely spaced frame than a gypsum ceiling

Safety and installation advice

Installing a ceiling involves both the structure and the electrical work above it, such as running wiring and cutting holes for downlights. It should be done by a specialist tradesperson, to calculate the load on the framing correctly, prevent the ceiling collapsing, and prevent the danger of current leakage.
