After 2 years we had mold behind the blanket on our North wall that is above grade.

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 ...

I hired a Green Tech Insulation to re-insulate my attic, have about 10 inch of insulation, they will add R-50 blown fiberglass, up to 22 inch high, they promised me it will cool my home during hot summer days. They will also install baffle system, extend the wooden box ( door to come in attic), insulate hatch, and use weather stripping around door. They ...

For an uninsulated shed I usually find exposed studs more useful for hanging/storing most tools, with the occasional board where that's not true. Anyway, for a dry, uninsulated, unheated shed, you need not do anything more than nail (or screw) it to the framing. I would actively avoid @Chris Cudmore's "gap" suggestion, however, since it sounds like making ...

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 ...

Ok, since you know that thermal insulation is crucial in order to avoid ice damps I will make the long story short: two places are crucial when it comes to insulating roofs. Doesn’t just put thermal insulation horizontally, on the floor of your attic; put it between roof rafters and if temperatures are REALLY low you can put it even around rafters. I would ...

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 ...

Practically speaking, SIPs are about it. Sounds like you might be thinking of some of the hopeful but largely unrealized press releases for autoclaved concrete or foamcrete (two different products, both with VERY limited practical availability despite nice websites and articles) though the "dimensional lumber sizing" aspect does not fit with that.

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 live in Lahore and all both weathers are at their extremes in this city; it gets up to 55 °C in summer and -2 °C in winters. I also live on the top floor and face immense heat, plus I am not allowed to alter the house so I can't put insulation as I don't own the space. So I have installed wooden shades above the windows. Also I have covered my ...

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 ...

We built a bucket truck garage two years ago. It has a 13' ceiling with a 5' stuccoed concrete block wall and ordinary 2"x6" studs above that. And of course the 4:12 pitch roof adds another 2' average height above that. A 15' ceiling leaves a lot of air space overhead to heat before the rest of the garage is comfortable. The garage has a 10'x10' insulated ...

A light fabric shade on the terrace will cool terrace considerable and also help to make a shade for small parties. This is the cheapest and the best which I am planning to install on my terrace.
