Re: New house frame issues 335Dec 20, 2015 6:36 pm Stewie D Quote: one question. what is better between the engineered joist (smartjoist) and the timber-webbing joist (steel and timber web)? why different tradie use different joist? They might have different strength gradings between the two types of beam. If the engineers or the design of the home is restricted to a 240mm floor joist then a common beam like the smartjoist might be used. Where they need more strength over a certain part of the house but they are still restricted to a total joist depth of 240mm then the web joist may have been used. I have seen some builders who used the web kind use them in bathrooms so the plumbers can run their sewer pipes without hacking the joists as they so often do with solid timber joists ( or Hyspan, Hyjoists etc ). Stewie So, do you mean that Web joist is stronger than smartjoists? both joists are still 240mm high, right? which one is more expensive then? How do they run the central heating/cooling system through the web joist? as for smartjoist, they will drill the holes like they did with the plumbing. Will drilled holes weaken the strength of the joists to a certain extent? Re: New house frame issues 336Dec 20, 2015 9:07 pm Without looking at the specs or tech sheet from the manufacturers I couldn't tell you. A Google search would turn both of those up pretty easily. At the design stage the AC guys plus the designer would look at the flooring plan and run their ducting parallel to the joist until they could change direction somewhere where it wouldn't impact the floor joist strength by cutting a whacking great hole in it. Drilling holes in the centre, you are allowed up to a certain diameter depending on which type of joist you are looking at. Once again that would be mentioned on their tech sheet. Stewie Re: New house frame issues 337Dec 21, 2015 5:54 pm I just checked my frame today. Most of the stud wall frame used MGP 10, some use MGP 12. is that the reason they use single top plate as it is stronger than normal F5? Re: New house frame issues 339Dec 22, 2015 5:12 pm Yeah, so I believe that why they use single top plate. It should be alright I guess. This is 100% true.
