Measuring true cost of any building material goes beyond the initial product cost.
Product Cost ~ RASTRA panels may cost slightly more than traditional building materials on a given project, however, RASTRA provides overall savings that offset this slight increase. These include: potential tax credits, installation time-frame, elimination of membrane and wire mesh with stucco applications, and the elimination of vapor barriers.
Installed Cost ~ RASTRA panels install much faster and require less construction management oversight. The building cycles are shortened; which makes the properties more readily available in the real estate market.
Life-Cycle Cost ~ RASTRA is the least expensive option by far over the life of the property. Heating and cooling costs are reduced by an average of 40% or more. Maintenance costs are reduced, Rastra walls do not need extensive care and there is no timber which warps and degenerates. The HVAC unit can be downsized and would have a longer service life based on operation reduction to maintain climate control. Insurance premiums would also be lower. As energy costs continue to rise, and as ICF construction is more widely understood, it is reasonable to project that RASTRA houses will command a 10-15% premium over comparable wood frame homes in the near future. And finally, the resale value of your property is higher.
