Q:I live in a flat and have constant leaks coming through my ceiling, there is a flat above me. The problems had previously came from the guttering on the roof not being cleaned properly and when it rained the water would leak in to the flat throught the ceiling and electrical sockets. The ceiling is plasterboard and my landlord doesnt seem to be fixing the problem properly, when they do come in they let it dry put a skim of poly filer over bits thast are coming off and repaint over it... even though you can still see the lines of the plasterboard coming through. Does anyone know how my landlord should be doing this properly so i can get this sorted as it hasnt been raining and i know have leaks again this morning with bubbles in the ceiling.

Its not a big issue, if your landlord is not willing to fix this problem, you can do it by yourself, there are lots of online resources from where you can choose a good product and apply it on your roof, i am also going to recommend a link and hoping it can be helpful for you, check out the link in the source box.

Q:Three building materials, plasterboard, brick, and wood, all the same thickness and area, are sandwiched to form a wall. Temperatures are 27 degrees Celsius at the inside plasterboard surface and 0 degrees celsius at the outside wood surface. Find the temperature where the plasterboard meets the brick and where the brick meets the wood.k for plasterboard = .40k for brick = .70k for wood = .2

1/0.4+1/0.7+1/.2 = 7.5+1/.7 or about 8.93 the plasterboard drops 27*2.5/8.93 C : about 7.7C so temperature at plasterboard/brick is around 19.3 C the wood drops twice as much about 15.2C so brick-wood interface is around 15.2C. Appropriate numerical precision when the conductivities are given to 2 significant figures means your answers should be about 19C and 15C. The brick is awful! Have a look at the link below; even thermal grease isn't much worse than this brick but the values do seem to be pretty typical.
