Price questions
How much is rockwool insulation per m² in South Africa?
Vulcanite Armor rock wool blanket costs from R235,24 per m² (Blanket 100, 40mm) to R574,24 per m² (Blanket 120, 100mm), incl. 15% VAT. Every roll's price per roll and per m² is in the table above.
Why does the price per m² change with thickness?
A thicker blanket holds more rock wool in every square metre, and roll length depends on thickness: 40 and 50mm as 5m rolls (6 m² per roll); 75 and 100mm as 3m rolls (3.6 m² per roll). A roll therefore covers a different area at each thickness, so compare sizes on the per m² column rather than the price per roll.
Do you give bulk or project pricing?
Yes. Rolls can be ordered online at the published price per roll. For 50 rolls or more, or a size we do not list, email us for a quote.
