Confidential & Proprietary Ageing in the B&C Environment Spaceloft’s thermal insulation is derived from its nanoporous structure. The performance is passive. There are no blowing agent or vacuum requirements to deliver this performance. This offers a constant design performance independent of time or within the realms of the B&C domain temperature or humidity.
