I have got it into my head that if houses were turned upside down like BOATS, and filled with water - the water would come cascading out so fast that and you cannot fill the building with water no matter how long or how hard you tried ? Lets imagine it was HEAT you are pouring into it, then I hope you can see what I am getting at, insulation is porous, insulation is laid in short and long strips and laid in patch-work-quilt rolls. And heat pours out of building non- stop. For instance on holiday last week in Keswick I saw a house with 10-chimneys, ten x 8-inches round big blooming disused chimneys and dreaded thinking about his heating bills?
EXAMPLES SEEN ON MY TRAVELS. Seen often by me inside unfelted house roofs (tiled roofs) meaning houses with no roofing felt placed under the roof tiles) with roof tile gaps so large between each tile -you can easily look down into the street below and see what is going on. Also you can hear conversations being held and watch small birds diving and crawling under the roof tiles to find, build or enter their nests. Eaves Soffit gaps are numerous, sometimes as many a 60 large 16" xs 8" soffit gaps are located in the roof eaves, you can look down them and see daylight, feel the wind on your face, or look into the garden? You then have another 501 other gaps which start at ground level and finish at the chimney tops all allowing water, vapour or heat to escape. And if heat gets blocked, like water it diverts into another escape hole and away. So, it needs to be asked does glass wool or fibreglass do any real good, or is it a bogus claim?
