Gypsum Board.
Gypsum is one of the more climate-friendly non-natural building materials. It is the clear standard choice for interior walls and ceilings. Read the numbers together with function, lifespan, detailing and the specific building element.

How to use this assessment
The assessment of gypsum board is a first decision basis. Carbon numbers, density and lifespan give a point of comparison, but the material must always be read together with structure, moisture, fire requirements, detailing, maintenance and the condition of the existing building. A good material choice is therefore both a data question and an architectural judgement. The useful next step is to clarify which questions should be examined further before the material is specified in a project.
What is gypsum board?
Gypsum boards are used for interior walls and ceilings and are standard material in modern construction. Gypsum is a mineral material (calcium sulphate) extracted from nature or as a byproduct from power plants. It is fire-retardant, easy to install, and very suitable for interiors.
Carbon Footprint Compared
Negative carbon footprint (green) indicates carbon storage. Data based on EPD averages from ECO Platform and estimates per EN 15804.
Typical Applications
- check_circle Interior walls and partitions
- check_circle Ceilings
- check_circle Fire-protected structures
- check_circle Bathroom cladding (moisture-resistant gypsum)
In Renovation
Gypsum boards are the standard material for interior renovations: new partitions, dropped ceilings, and surface renewal. Fast to install and easy to paint and finish.
Questions about gypsum board
What is the difference between standard and moisture-resistant gypsum?
Moisture-resistant gypsum (green) is treated to withstand short-term moisture exposure. It is used in bathrooms behind tiles and in damp rooms. It is not waterproof alone — it requires a moisture barrier or tile covering.
Can gypsum boards be recycled?
Gypsum can be crushed and recycled into new gypsum production or as a soil amendment (pH regulation). The market for recycled gypsum is growing. Many producers (KNAUF, SAINT-GOBAIN) accept returned gypsum.
Is gypsum board a climate-friendly material?
Gypsum is one of the more climate-friendly non-natural building materials with relatively low GWP. Use of FGD gypsum (byproduct from flue gas desulphurisation) further improves the climate profile.
What are the fire properties?
Gypsum releases bound water in fire, which delays fire spread. It is used in fire-rated constructions (F30, F60, F90). Greater board thickness and double layers provide better fire protection.
