Insulation and Spancrete
Posted by dirttodone
Below are the latest construction photos.
This is a photo of what Spancrete looks like. Once the sections are put into place, they are tag welded together. Then a waterproof membrane is put over the panels, followed by 4" thick concrete poured over the top. In this project, before the concrete was poured, pex tubing was run so the garage could have in-floor heat.
The Icynene foam insulation was chosen by the homeowners. They liked the fact that it creates a continuous barrier and helps buildings achieve U.S. Green Building Council's Leadership in Energy and Environmental Design (LEEDâ„¢) credits. Golden Eagle Log Homes supplies R-38 fiberglass ceiling insulation and R-19 fiberglass wall insulation as a standard in their complete package.
The dormer loft elliptical casement window adds a touch of class. This photo shows how tightly the Icynene seals up the home.
This photo shows the basement bedroom. The ceiling height is 9 feet. The sill box is very well insulated with spray foam. The window is large enough for egress (an emergency fire escape.)
This photo shows the basement prow wall. The big dark object is the hot tub spa set on edge. It needed to be put in the home's basement before the home was done or else it wouldn't have fit.
The unevenness of the foam will be shaved smooth once it's dry. The family is hoping the extra investment (about $15,000) will pay for itself with energy savings.
This photo shows what is under the Icynene foam on the vaulted ceiling. The pink and grey foam baffels are venting the roof. They are continuous from Golden Eagle Log Home's standard maintenance-free aluminum soffit up to the ridge vent.
The garage walls are insulated with Icynene and the ceiling will have R-38 fiberglass batt insulation.
This is a view of the ceiling. The black spot is where the ceiling fan will be attached. Golden Eagle Log Homes designs a small flat area in the peak of the ceiling for a number of reasons.
1. For extra roof strength.
2. Energy efficiency using fiberglass batt
3. A stable and straight surface for mounting the ceiling fans and future trimming out.
Here is a nice view of the rooms under the garage. Notice the Spancrete ceiling. For an extra $15,000 to $30,000, depending on the size of the garage, you can increase the square footage of the home very economically.
