My bungalow in Ireland has basic Jablite slab insulation in the cavities of 50 mm thickness. The walls are concrete block. I am not sure how effective or complete this may be. I have recently built a roofed conservatory with underfloor heating and 100mm floor insulation , double glazing and fibreglass roof insulation and it is noticeably warmer without any heating on.
Is there any product that can be injected into the original cavities to boost the UV value? Otherwise all i can do is double up on the loft insulation.All replaced wndows are now double glazed.
