SLV Internal - LOW GWP is a unique and innovative product with which we, as a company, are fully committed to sustainability and ecology.
By significantly reducing global warming potential (GWP) by 68%, SLV Internal - LOW GWP is the most environmentally responsible sprayed mortar available on the market today.

Mixing on demand
To optimise our service, we produce customised blends. At our modern, fully equipped site in Blandain, near Tournai, we can blend, process and package a wide range of dry powders. These blends can be produced under the customer's brand name and labelled with a customised design.
We deliver a complete finished product under the ISO 9001 quality label guarantee, packaged and labelled according to your specific requirements. Need more information about the mixtures you have ordered?
Composition
SLV sprayable products, composed largely of Belgian raw materials, consist of a mixture of vermiculite, cement and a number of carefully selected additives.
The combination of exfoliated vermiculite, a durable expanded mineral that acts as a thermal barrier, with the best cementitious binders, mineral fillers and additives available, results in a completely non-combustible product, class A1, in accordance with European standards.
