If you're going to us loft then fix it at the top so that it hangs. That way it won't slump. Oh, and just pack the mm into the space. The 'density' is what you want for accoustic performance. Thanks all. Ah - hadn't appreciated the "slump effect" - good point. The price difference is rather wide, especially as our walls are 2. Worth bearing in mind that loft insulation has sod all acoustic properties to it, no matter how much you cram it in.
Thanks Spudler, that's the sort of info I need. No point using the loft insulation if it won't do the job. Any recommendations whose best to supply mm wide, 70mm thick insulation slabs? DIYnot Forums. Stud wall insulation Discussion in ' Building ' started by ads1 , 19 Aug Hi all, I am in the process of building a stud wall to divide a room in two.
The room was divided originally when the house was built but the previous owners knocked it down to make the master bedroom bigger.
I wish to put it back. The walls upstairs are all stud walls of 60mm thickness. I am going to make the new wall slightly thicker as I have the wood already. My question is does the isulation have to fill the thickness of the wall compleatly? The stud thickness is 47mm. Could I use 50mm Celotex board and compress it by the 3mm, or use thinner insulation.
Any recommendations? Many thanks. PrenticeBoyofDerry , 19 Aug Thanks x 1. If I go for 50mm Rockwool would this be ok to compress slightly to the 47mm stud thickness? Rated excellent.

Fill type insulation, as the name implies, is using granules of material to fill a certain space. This insulation type will require professional help to install. Blown-fiber insulation involves blowing in the materials to fill up space, particularly useful for areas that are harder to reach. This type of loft insulation is installed on the roof. The sheets are usually hard, stiff, and their applications can range anywhere from preventing moisture build-up, to acting as a fire retardant.
Here is a brief list of the common materials used in loft insulations and a description on why they work well as insulators:. The stack effect is used by architects to plan how air circulates inside a building. Most notably, what causes the stock of it is not the air itself but the temperature of the air. The difference in air density between an indoor area and an outdoor area may cause one of two effects :. During the wintertime, what happens is that the hot air rises to the top of the building, and as hot air rises, cold air will take its place at the bottom.
If the inhabitants downstairs feel too cold, they would raise the thermostat, and the reverse what happened. Since there is hot air at the bottom, then the cold air from the top would start going downwards. Understanding the stack effect and why loft insulation is designed as it is, is essential information when considering what loft insulation type should be used for stud walls.
A stud wall is a hollow wall, usually used as a partition between spaces. It can be made with either metal studs or wood studs. The main difference between the two is they provide different solutions for different problems; in other words, the best type is situational. In the case of insulation, however, the wood-type stud walls would be better because they are easier to manipulate.
The purpose of a stud wall is the same as any other wall, which is to hold up any windows, utilities, doors, and to provide insulation.
