While closed cell foam will perform a bit better than fiberglass in noise reduction, there are much better ways to tackle this for the same or lower cost. What you really need for sound isolation is to add mass between the living units and to mechanically separate them. If both living areas are sharing a wall, building with double studs that are staggered ...

Given what you know about how you will heat the rooms differentially, insulation is good. I'd go with mineral wool (or fiberglass) since some sound isolation is often desirable between bedroom and bathroom and foam is not great at that application. If you will be doing the bathroom walls with a moisture barrier no additional vapor barrier on the insulation ...

In general you have the right idea with placing insulation between the thermal masses of two brick layers. This will work well in any climate. However, you can make some improvements. Here are a couple I can think of: Use thicker insulation. 5cm may not be enough. Shoot for 10 cm. Result: lower heating and cooling bills, greater interior comfort. Plaster ...

There is a product called Thermo-Lite which is probably what you want. it's available in a sheet/board form and it contains a closed cell foam with fiberglass reinforcement. It's incredibly nasty to work with (fiberglass dust) and it isn't terribly strong, but it's leagues ahead of any type of foam insulation board that has been suggested. I work in the ...

Lots of things are better insulators than wood. Most of them aren't strong enough to be structural, or not better enough at insulating to bother, since generally people insulate with insulation materials that are designed to be good at that. If the thing you're describing existed, people would almost certainly build houses out of it instead of wood, unless ...

I was in a situation like this a while ago. I was also under a constraint where I could not make modifications of any kind (no nails, drilling, etc). So here is what I ended up doing. Bought a bunch of C clamps. Since the room had open beam ceiling, I could use the clamps on the beams. Put a clamp on every fourth or fifth beam so that the clamps were ...
