Source: official Kalsi Building Solutions site (kalsi-building-solutions.com), product pages for KalsiRata, KalsiBoard Ling, KalsiQua, KalsiClad, the product list and the home page, read 23 October 2026. Per-m² weight is sheet weight divided by nominal area (homeX analysis, not maker data). Data gaps: no prices on the pages; no SNI number or test report is shown on the pages we read although the home page title says "SNI-certified"; flexural strength, density class, fire class and moisture content are not given; specifications of the other nine products, accessories and corrugated roofing were not read; the production site of each product is not stated; no shop or distributor was checked. Claims of water, fire and termite resistance are the maker statements. Confirm with the maker hotline before ordering. Data as of 23 October 2026.
Choosing a Kalsi fibre cement board thickness by application
homeX analysis based on the maker pages: for a renovation ceiling over a timber frame, KalsiRata 3 mm is described as a plywood replacement with open joints; if you want flush joints with compound and tape, the KalsiBoard Ling page lists 3.5 to 6 mm variants and recessed edges on the 6 mm. The weight difference shows in the table calculation: about 4.4–4.8 kg per m² for 3 mm up to 9.1–9.5 kg per m² for 6 mm, so the frame and hangers need to match. For exterior walls the KalsiClad page asks for a steel frame and a wind-load calculation; for wet areas KalsiQua 8 mm is marketed as a board that needs no additional waterproofing, a claim to confirm in writing with the maker or installer before relying on it.
Buyer tips
- Compare weight per sheet and per m² before choosing the ceiling frame and hangers.
- Ask the maker or installer to confirm the frame system, screws and compound suitable for the chosen board thickness.
- For wet areas, get written confirmation about waterproofing before skipping it.
- Ask the supplier for the data sheet and SNI/test certificates, as the product pages do not show them.
