A library has two air standards in one building: a reading room that must stay quiet and draught-free, and stacks that must hold stable humidity with no condensation on duct surfaces. This article sets out the acoustic, draught and humidity requirements and how JVTIADUCT fabric ducts meet them.

A school canteen serves several hundred people inside thirty or forty minutes, then sits almost empty. This article looks at peak load, grease and moisture, and the daily wash-down, and explains how JVTIADUCT fabric ducts answer all three through low-velocity, large-area air distribution that can be taken down for cleaning.

Most hypermarket sales floors have no suspended ceiling, so ducts, hangers and services sit inside the customer's line of sight, while refrigerated display cases keep cold surfaces in the same volume. This article looks at three practical constraints on the sales floor - appearance, condensation above fresh zones, and the night refit window - and explains how a permeable fabric duct answers them, how to select by zone with JT-H, JT-T and JT-N, and why services should be coordinated at concept stage.
