Some installers believe that placing these systems in a garage or attic space may make the system more efficient by decreasing the difference in temperature. But it’s precisely because of these disparate temperatures that you should place your heat pump and air conditioner condenser outside.
Discerning construction professionals are turning to raised-heel trusses thanks to the increased attic space they produce. This space is then utilized for larger amounts of cheaper insulation which reduces the cost of insulation and provides a more effective building envelope and a greener home. Raised-heel trusses offer many environmental and cost-saving benefits.
When installing attic insulation, a case can be made for both radiant barrier sheathing with typical types of insulation as well as spray foam insulation. A number of factors should be taken into consideration when choosing between these two, especially the climate zone that you’re building in. Radiant barrier sheathing is inexpensive and reflects thermal radiation to keep attic spaces cool. Spray foam offers insulation and provides some sound proofing from outside noise.
