HVAC Sizing

Since SIPs are so energy efficient, the correct sizing of your HVAC is a crucial step in the building process. Sizing requirements used in traditional construction must be modified to meet the superior standards of SIPs. This often means the size of your HVAC operating system can be substantially reduced, ultimately saving you money. The incorporation of an air to air exchange is required for all SIP structures. Whether you choose your own HVAC installer, or you work with ours, we will assist in determining the correct HVAC system for the energy efficient structure.

We found them to be, dependable, conscientious, with superior attention for detail, and extremely easy to work with. After our initial experience, there was never a second thought as to who would build our dream home in Denmark. Our new home is everything we hoped for and more!
