will be from solid material, lead would be ok but to expensive and bad what belongs room atmosphere and condensate problem. So solid stones (f.e. brick) and maybe solid wood will bring the best sound comfort. Otherwise only solid materials can give a real thermal insulation, if this may be...

But proofs? The difficulty is to compare the efficiency of additional thermal lightweight insulation with the situation before. And here I can offer a hit, which makes the german insulation industry more than nervous since years: Watching the heating costs of three big apartment buildings in...

because I do not say there is no damp at foundation walls and garden walls and so on. What I say is that there is no capillary transport responsible for the damp. Its natural that rain is spraying on the walls nearby the ground, that salt can take up hygroscopic damp, but the salts will come in...

you should consider that it can not stop IR radiation which causes about 99% of thermal losses through walls and roof. On the figure you can see the temperature after 10 min red light radiation on the opposite of insulation boards. This experiment (Lichtenfelser Experiment) I did together...

is a big deal all over the world. So I like it to awake the interest of another point of view. My building and planning experience since over 20 years under responsibility as architect learnt me not to distrust the good old craftsman, whose buildings stand better in our landscape than any new...

are impossible, because the capillary resistance between fine pored stone and rough pored mortar is extremly high, will say infinite. So the bigger pores of mortar can not suck up any water from fine pored stone. This is proven by a lot of examples and everybody can test it out at home...

Oh, how much wise words referring the rising damp! :idea: Perhaps some additional remarks are allowed: Rising damp does not exist in masonry, because there is no capillary transport between fine pored stone and rough pored mortar, even if the stones are in water for a very long time...

if you notice the missing of damp proof course, the dampness in your walls have nothing to do with them. If they are there or not - they will not work anything because there is no capillarity between fine pored bricks and stones and rough pored mortar in the joints. So the damp in parts of your...

Hi Ruggie there is nothing to do with your fine 'damp course'. Besides - a damp proof course in masonry work will not work better against 'rising damp' than a normal mortar: There is no capillarity between fine pored stone (like bricks) and bigger pored mortar at all. Try it out with two bricks...

I agree with the criticals against rising damp. There is no capillarity between fine pored stones and rough pored mortars at all. So only condensation, hygroscopic salt burdens in the wall and plaster, pressuring water in the soil and spraying rain can moisture up the walls. What helps...
