Can Isover CWS be used below DPC level in masonry cavity walls?

Isover CWS is manufactured with a water-repellent binder, meaning that it can safely be used below DPC level in masonry cavity walls without the risk of ground moisture bridging the DPC via capillary action.

Can ISOVER Spacesaver be used in a sloped or vertical application?

Isover Spacesaver is a low-density loft insulation roll, and as such we would only recommend it be used in a horizontal application as it may not self-support in any sloped or vertical application.
