Cavity wall panel insulation system using dynamic air flow to increase efficiency and reduce U-values, by utilizing the building envelope as a heat exchanger. External air entering the property is pre-warmed, by heat that would otherwise escape from the building and by moving the air through the insulation the heat loss is recycled back inside. Jablite Dynamic Cavity requires a mechanical extract ventilation system within the property to draw air through the cavity.
