Engineering notes on closed-cell rubber insulation: how the wall thickness is calculated, how the materials compare, and how the product is classified and declared on export. Written for the people who specify, install and clear it — not for search engines.
Sizing for condensation control: the four inputs that decide the wall, how the dew point moves with the room, and why a published thickness table is right for someone else's project.
The three materials that compete for HVAC pipework, compared on the same basis — including the jobs where mineral wool or PU is the better answer.
How rubber insulation is classified on export from China, the declaration elements customs asks for, and which documents travel with the container.
Cartons per container, the metres that gives you, and why the answer depends on pieces per carton rather than on the size of the box.
Enter pipe size, fluid temperature and the room's temperature and humidity: the tool returns the dew point and the minimum wall thickness to stay above it.
