It is designed for energy-efficient renovation and can contribute to reduced energy use. Environmental documentation (e.g., EPD) is available if applicable.
It is injected into the cavity through small drill holes in the mortar joints. The material forms in-situ and fills the cavity evenly. Drill holes are sealed in the original mortar colour to preserve the façade’s appearance as much as possible.
ISOCLAY® is low-emitting. Refer to the product documentation and emission certificates available in the downloads section.
ISOCLAY® is mineral-based and non-combustible, with a reaction-to-fire classification used for high fire-safety requirements (provide exact class on your tech page).
The foam is designed to spread and set without creating damaging expansion pressure when installed correctly.
ISOCLAY® is water-repellent and vapour-permeable, but suitability depends on wall condition and exposure. A cavity assessment is always recommended.
It fills the cavity seamlessly, helping reduce heat loss and unwanted air movement, which can improve thermal comfort and reduce draughts.

ISOCLAY® is a mineral, non-combustible in-situ insulation foam designed for cavity wall insulation in double-leaf masonry. It is used in cavity walls for both renovation and new build applications, especially where a seamless fill and fire-safe performance are important.
