Wurlitzer, 10 October 2005OK, here we go: I'm going to be building a new room at the end of the garden of my London terrace house. It will be primarily for rehearsing and mixing, but I'd like to…
sharward, 10 October 2005Much better! 8) Are you referring to a 3" distance between the wooden frame and the concrete block wall? If so, then you'd add the width of that distance to the depth of…
Wurlitzer, 10 October 2005I mean 3" between the concrete blocks and the plasterboard. So the timber frame would actually jut into that space. That sort of thing is simply not going to be…
sharward, 10 October 2005Perhaps you don't need to isolate your inner slab if the entire building is standalone. Are you married to the idea of using 8" concrete blocks? I'm thinking that if you…
Wurlitzer, 11 October 2005Yes, I'll be going for solid concrete blocks, of the highest possible density. They are quite common in the 100mm thickness. The 190mm thickness that I'll be using is…
knightfly, 13 October 2005Just did some basic calcs on your options - keeping the total wall thickness constant, using 100mm concrete block with the extra 90mm added to the air gap, improves the…
Wurlitzer, 13 October 2005Hey Steve, I really appreciate your doing this, though I haven't got my head round the graph yet. When you say it would lower the Low Frequency TL - what about other…
Wurlitzer, 13 October 2005Whoa - I just had a thought. I'm pretty certain my brother-in-law said that for a building with only one heavy structural wall (ie this one, because the inner wall is…
knightfly, 14 October 2005Another reason for masonry outer, especially in foggy old London and thereabouts, is WATER retention - masonry can retain approximately 100 TIMES as much water as gypsum…
knightfly, 14 October 2005Standing/sitting corrected is better than laying, rejected :wink: As to wall construction - if you build 4" outer masonry and "4x2" inner stud frame with 2 15mm gypsum,…
Wurlitzer, 18 October 2005Steve, I just spoke to my man who's here today to start digging. Turns out I'm wrong about the building regs. We can either use 190mm blocks, OR use 100mm block with…
Wurlitzer, 27 October 2005It now looks like, due to engineering factors brought about by the split foundation we will be using, the total wall thickness will need to be 360mm instead of 300. So…

Wurlitzer, 28 October 2005Sorry, I got the maths wrong in that previous post. Also, the positioning of the outer walls has changed slightly again. The two possibilities are: a) 100mm block >…
Wurlitzer, 29 October 2005Hehe - you just addressed the window issue in my other thread. There's another factor which is that the thinner blocks are considerably cheaper, and easier to carry.…
