Blockwork Vs Timber Stud

ok, i have adecision to make! i currently have a single leaf masonry garage wall and i need to build the inner leaf. so, should i use blockwork or timber panels? most (if not all) post ive read only mention timber... :-/ i wouldve thought blockwork would be more dense?

you can use both however with stud walls you and install insulation inbetween the studs and still have a airspace. studs are faster cheaper and you can get the same or better results fom adding layers of drywall. joey

I think im gonna use blockwork as I can get the brickie to do the new door slapping and brick up the garage door at the same time. My next question is with regards to wall ties. These ties would need to be plugged and screwed to the outer leaf and bedded within the mortar joints of the new internal blockwork leaf at 450 vertical & 900mm horizontal centres. What sort of impact would the wall ties have to the sound isolation of the room? Ps. Im still waiting on ‘the book’ turning up.

your talking of a cavity wall now in terms of general building. this is not how you get the best isolation. you want mass air mass. see http://www.mason-ind.com/masonind/home/index.cfm for isolated ties.

cheers for the link!

What are these "ties" you refer to doing? You have an outer leaf, now you need an inner leaf. You want air between the two leaves not ties, right?

xSpace: these are standard wall ties used within a traditional brick & block construction. maybe something like a PPB on this page would do - http://www.ancon.co.uk/main.asp?pageID=146 joey: cant find aynything on that page, mate. do you think a sleeved wall tie (see above) would be any better?

What would you do if you had a single leaf masonry garage that you want to convert to a studio space? 1) Build a blockwork inner leaf (disadvantage: wall ties fixed back to existing - required for stability) 2) Build a timber inner leaf (advantage: no fixing to existing - fixed top and bottom) 3) Thicken up existing leaf using timber strapping and RC There are a couple of things that are definite ie. a new door slapping, a window in place of the garage door. Also, the floor will be insulated and boarded and the ceiling will be strapped with RC. Cheers.

how thick are your original walls. you cant use a slip joint defeats the object of a tie. building regs will say that a single leaf wall has to be 215mm min if it is you can build a second wall 215mm and it wont need tieing if its not then you need to add another layer of blocks/bricks to get it thick enougth. creating your first leaf then your back where you started either build stud walls which i recomend or 215mm blocks. http://www.mason-industries.com/masonin ... g_over.cfm these clips are isolating ties basically. i contacted them and the do both timber and masonary clips.
