Normal insulation batts will be at least twice less effective inside steel framing than in timber and insulating in traditional way will be leading to steel contraction/expansion, especially, in the areas where diurnal temperature changes are significant. There might be some impact to wifi and phone signals, however, considering that steel framing is not very dense - this should not very significant. Metal profiles are certainly much faster when it gets to gyprock installations, e.g. whole Knauf system is designed around metal studs for very obvious reasons. Re: Timber or steel framed houses? 9May 10, 2021 1:54 pm skuzy couple of other questions.. and apologies if these are dumb 1) noise levels from the steel expanding and contracting from heat... is this a serious issue? 2) any impact on phone/wifi signals 3) mounting pictures/tvs etc on a steel frame.. is there something different that needs to be done here? Hi Skuzzy no all good questions. Answers are: 1. We insulate our homes really well so there isnt too much noise when compared to the noise that comes from a metal roof 2. Possibly, had no complaints. As standard we run cat 6 cabling throughout especially to all the TV points as we find that wifi isnt that great anyway with all the insulation and hebel floors we put in 3. You just use different screws for the metal frames but we put 12m ply into all the walls where we know the TV's will be mounted to make the process easy for TV installation hope this helps cheers Simeon Simeon McGovern Affordable Custom Homes, We design and build to your budget Ashington Homes www.ashingtonhomes.com.au Re: Timber or steel framed houses? 10May 10, 2021 1:55 pm just checking i understood this part correctly.. "Normal insulation batts will be at least twice less effective inside steel framing than in timber and insulating in traditional way will be leading to steel contraction/expansion, especially, in the areas where diurnal temperature changes are significant." Twice less effective - in providing insulation against temperature changes? OR Twice less effective - in limiting the amount of noise from steel contraction/expansion I ve noticed a few builders now are offering (or asking) for steel frame option with color bond roofing (either at no cost or v/cheap upgrade) - but then nothing is said about what changes are being done to the insulation for example. Then reaslitically speaking.. what can be done about this? Prior to the timber shortage, steel frame was already an option.. though i didnt see it being a popular one due to cost.

Depending on your climate zone this will probably be R2.0 to external walls and R.4.0 or 5.0 in the ceiling in my opinion to do it properly you need to sark every external wall and tape the sheets tight. all external penetrations need to be filled with expandable foam and ideally you need expandable foam behind the studs. you should also install insulation in all internal walls and between your floors. There is a reason that project home builders deliver a much lower upfront cost regards Simeon Simeon McGovern Affordable Custom Homes, We design and build to your budget Ashington Homes www.ashingtonhomes.com.au Hi I am wanting some opinions about the build of a steel shed I am going to get one about 4.5 x 2.5 m steel shed and the height will be about 2.3-2.4m high The one I am… 0 14458 This is 100% true. You can not hang anything on steel frames. very frustrating 8 8052 Engineering timber is certainly a less fuss option, times cheaper to supply and install and better withstands humidity. 1 15924 |
