The extra $5/m2 buys you R 1.0. It probably is similar to the difference from upgrading your bulk insulation by R 1.0 Re: Sarking, Wall wrap sisalation & insullation - what is it? 11Aug 18, 2009 11:30 am FireFox so its a good idea to put it just under my colorbond roof (which is dark blue) for heatsoak? price i got from them was $8sqm ill still have bulk insulation for the ceiling I think its becoming more of a standard now for builders using colorbond, bluescope also recommend it for reducing noise such as metal creaking and rain noise Re: Sarking, Wall wrap sisalation & insullation - what is it? 12Sep 18, 2009 5:18 pm Anticon (from anti-condensation) is becoming a more popular alternative. Anticon Roofing Blanket consists of a glasswool blanket adhered to an impermeable reinforced reflective foil facing installed under metal roof decks. Thus providing both condensation protection and efficient thermal protection. It comes in a range of sizes from 60mm (R1.3), 80mm (R1.8 ), 100mm (R2.3), 110mm (R2.5) and 130mm (R3.0). Exact thicknesses and R values vary with manufacturers.

Re: Sarking, Wall wrap sisalation & insullation - what is it 14Sep 27, 2012 6:26 pm Just resurrecting this thread as I'm trying to figure out if we have enough sisilation and/or insulation in our new house. It states that it comes with "wall sisilation" and "R2.5 batts to the roof space". Is this going to be sufficient insulation in winter, or is it recommended getting more? We declined roof sarking because we don't have a colorbond roof (I've heard that's when it's important to sark) and because it was ridiculously expensive.

To this end you should look at keeping the ceiling area cooler by sarking under the tiles. Quote: We declined roof sarking because we don't have a colorbond roof (I've heard that's when it's important to sark) and because it was ridiculously expensive. As stated above $3 - $5 psm is cheap in my book for the benefits achieved. Unless the builder is trying to rip you off blind then it shouldn't be expensive at all. Colorbond roofs should have foil backed batts blanket as sarking not the simpler and cheaper foil sarking that is more common under tiled roofs. I Quote: t states that it comes with "wall sisilation" and "R2.5 batts to the roof space". Not only should you have sisalation on the wall frames but you should also have 2.0 - 2.5 batts in the walls as well. If it was me I'd also ask for R 3.0 batts instead of R-2.5 to the ceiling as well. All these things just make your house more comfortable in both summer and winter as well as lowering your energy bills too of course. What type of sarking did he quote you ? How cold are your winters ? I can't imagine they'd be too bad in Brisbane. Stewie Re: Sarking, Wall wrap sisalation & insullation - what is it 16Oct 06, 2012 10:21 am Thanks, Stewie, there was no specifications on the sarking just "sarking to roof, cross ventilation may be required". They quoted $1,390 for this, which is probably not super expensive, but I just didn't think it was necessary under tile roof. I've asked for a quote for wall insulation, but haven't gotten it yet. We're seriously considering adding this. As far as how cold it gets here, we're looking at building out west of Brisbane, and it gets much hotter in summer and colder in winter than closer to the city (where we live now). It does creep below 0 sometimes, and above 40, when closer to the city it's on average 5 degrees higher/lower.

I've lived here for 17 years and only once had a slight frosting on my windscreen. Mostly never gets below 5-7 degrees in winter and no hotter than 32ºC with maybe once or twice getting over 35ºC in summer. Those R-values I quoted you are what we are aiming for at least if not more and we obviously don't have the higher fluctuations in temps that you do.

Stewie Re: Sarking, Wall wrap sisalation & insullation - what is it 18Oct 07, 2012 4:44 pm So I asked the builder about wall insulation, and they can give us R1.5 batts all the way around the house for an extra $800 (although according to him, we "don't really need it"). Is this going to do anything and be worth the money, or is it the kind of thing that doesn't really have any noticeable effect unless you go R3.0 and higher? I don't really want to spend much more than this on insulation. PS: It's 36 degrees here today (and we're fairly close to the city), and we're living without any form of aircon or wall insulation at the moment. It's almost unbearable! *lol* Settlement: 10.02.13 Slab: 06.03.13 Frame: 08.03.13 Lock-up: 05.04.13 Handover: 03.06.13 Build thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=59555 Brisbane Photography Re: Sarking, Wall wrap sisalation & insullation - what is it 19Oct 08, 2012 11:13 pm MalinViktoria So I asked the builder about wall insulation, and they can give us R1.5 batts all the way around the house for an extra $800 (although according to him, we "don't really need it")...... It's almost unbearable! *lol* Have you answered your own question ??? IMHO, If you're planning to live in the house as opposed to build-and-sell, then insulation, and the best you can get, is a MUST !! Depending on your particular builder, frame type, construction method and brand of insulation your builder uses there is actually a maximum thickness of insulation that will physically fit in your (external) walls. Find out what this is and use it !!!! Our plan is to spend $$'s on insulation and glazing to keep the home as comfortable as possible to reduce as much as possible the need for heating and cooling. I don't know what the price of electricity is up your way, but $800 doesn't come close to covering our electricity bill for either the summer or winter quarters. If we were to save (say) even 30% of our heating and cooling costs it wouldn't take very many quarters at all to pay back a (say) $2,000 or more investment in insulation. And I'm pretty darn sure that the price of electricity isn't going to drop dramatically any time soon !!! P_D ( IMHO !! ) .
