Superinsulation


superinsulation

[¦sü·pər‚in·sə′lā·shən] (chemical engineering) A multilayer insulation for cryogenic systems, composed of many floating radiation shields in an evacuated double-wall annulus, closely spaced but thermally separated by a poor-conducting fiber.

Superinsulation

The superinsulation of the building envelope minimizes heat gain during the summer and heat loss during the winter. Superinsulation involves substantially increased Rvalues combined with proper detailing for minimized thermal bridging and thorough air sealing for minimized infiltration. This strategy must be paired with controlled ventilation in order to maintain a healthy indoor environment.
