Browse Forums General Discussion 1 Nov 16, 2014 3:06 pm As it is getting hotter by the day and my bare colorbond roof is getting a lot of heat into the house I am trying to figure out a way to reduce it - one way I thought of is to retrofit Anticon roofing blanket on the roof. Another is to "blanket" my roof with solar panels (which will shielf the bare tin roof from the sun and create air gap naturally) but that is probably prohibitively expensive. What else can I try?

At this stage I am not totally convinced that is your roof. What I went through this on my house. 1. Built west facing pergola. Have very good effect by making west rooms habitable. Reduced load on AC. 2. Installed Blind (e screen) These helped a fair bit. I also tested and found the temp behind the escreen was more than 15 degrees cooler. 3. Installed Whirly Birds. I found that it took a few hours longer for the house to heat up. ie on hot days I was able to delay the time at which I needed to put AC on. 4. Installed trees on North Side of House. Still waiting for the trees to grow a bit more to feel the benefit. Re: Summer heat and ways to reduce it 3Nov 18, 2014 12:28 pm Despite the fact that it will not be cheap to do, installing a decent grade Anticon under your Colorbond roof will probably be the most effective, followed by a similar grade at least to the ceilings. What do you have at the moment ? Your walls should be R 2.0 - 2.5 as well. As per what BSTAR says, it will be your weakest link which if all the other insulation is in place could be your windows.

Why would you install trees on the north side? You would want as much glass on that side for the winter sun and warming. The best way is to position windows to take advantage of natural ventilation cooling using thermodynamic Flows (CFD) There is software around that simulates all that but you would need to incorporate that in new designs...... The only thing that is difficult to factor in is the future impact of adjacent building that have yet to be built, trees, effects of global warning etc Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs There may be answers here but can't find anything.
