If sourced correctly, it is a carbon sink, actually extracting carbon dioxide out of the atmosphere. Steel emits A LOT of CO2 during it's manufacture. A steel frame is thermally inefficient. Steel is a very high conductor of heat. This means in summertime heat can bypass the insulation, heating the house. This is called thermal bridging, & must be taken into account during the design stage. Timber is an appropriate material for a houses frame. The frame is inside the building envelope, protected from the environment. There's timber framed houses that have stood for hundreds of years. It just needs to be treated in termite areas. Timber is also cheaper, so why would you bother with steel? Re: Frames, Timber or Steel ?? 16Jun 01, 2017 4:18 pm Hi, My personal choice is steel but it depends on many factors like budget, your location, etc. If you are leaving in coastal area timber is good but otherwise steel is better. The builder may take more time to complete the house if you chose steel frames. Moreover, if you want to revamp your house in future, which require frame changes, it will be a problem. Thanks, Re: Frames, Timber or Steel ?? 17Jun 03, 2017 3:13 pm ddarroch Timber is WAY more sustainable. If sourced correctly, it is a carbon sink, actually extracting carbon dioxide out of the atmosphere. Steel emits A LOT of CO2 during it's manufacture. Then again, it depends on what your definition of sustainable is. Theoretically a steel frame should last a millenium, whereas wood frames can burn down, by eaten by termites, sag, etc, thus requiring demolition and rebuilding. Not so with steel. ddarroch A steel frame is thermally inefficient. Steel is a very high conductor of heat. This means in summertime heat can bypass the insulation, heating the house. This is called thermal bridging, & must be taken into account during the design stage. Dont follow that logic. A wood frame bypasses insulation in the same way and will conduct heat as well, but less efficiently as you state. But the rub is that on a very hot day, such as we experience so often now in these heatwaves every summer, timber actually soaks up and retains the heat well into the night, requiring you to use air con to cool your house down. Again, in that respect it is not so sustainable ddaroc Timber is an appropriate material for a houses frame. The frame is inside the building envelope, protected from the environment. There's timber framed houses that have stood for hundreds of years. It just needs to be treated in termite areas. Timber is also cheaper, so why would you bother with steel? Steel or timber, they are both inside the build envelope. Timber may not be cheaper in the long run if you have to annually pay for termite treatments. In my opinion, steel frames are easier to assemble and fix onsite than timber frames, particularly for a novice or unskilled builder. So there are some answer to your question as to why you would use steel. Re: Frames, Timber or Steel ?? 18Jun 08, 2017 12:12 pm Hi guys, Thanks so much for the responses, it helps! Now, I'm specifically looking for inputs on the below. I'm going to do Ducted air conditioning, some electrical stuff like downlights, external facade lights, light over garage, external side lights, hanging pendant lights (kitchen). Will there be any constraints if I go with Steel frame? I don't want to choose Steel frame and get caught out not being able to do any of the above - would appreciate your inputs please. I reached out to my electrical consultant (builder's) and the below was her response - If you have a steel frame access to the cavity wall is impossible as the steel fills the cavity. If it is a timber frame then the noggins are placed on the side so there is cavity to add additional items at a later date.

Will depend on the design of your steel frame but ours only has small noggins that take up less space than timber ones and regular pre cut holes in the studs and top plates making it straight forward to add stuff.

Not sure about the design - I've added a picture in this thread above if that helps? Will there be any constrains/issues if I do the below after handover if I go with Steel frames do you think? Ducted air conditioning, some electrical stuff like downlights, external facade lights, light over garage, external side lights, hanging pendant lights (kitchen). Please share your thoughts. That sucks! Hope it all works out. Good to move away from steel anyway for all your reasons, but it's also thermally poor. 16 18011 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 14551 This is 100% true. You can not hang anything on steel frames. very frustrating 8 8077 |
