what age is the brick houseAnyone have experience of insulating a brick house . I am nervous that the drill will damage the corner of the brick and the resultant appearance.
I see where your coming from, perhaps you could visit work where the cavity pump/drilling has been done previouslyHouse built in 1989. My concern relates to the potential damage done to the actual brick where the drill would chip the corners.
Brick allows more moisture into the cavity than blockwork - and is less suitable for full-fill insulation than rendered blockwork."cavity fill - which is usually not suitable for existing brick construction"
Forgive my ignorance Superman. but why is this so? Surely there is still a cavity between the outer leaf of brick and inner leaf of concrete blocks?
tell us more about this? have you a product or system you can link too?a breathable/waterproof clear coating on the outside
