Panelized construction allows for tighter fitting building components, reducing air leakage and ensuring quality. Deltec also offers four energy efficiency technologies for wall systems:
2x6 studs can be spaced at 24" rather than 16" to maximize space for insulation and optimize the amount of lumber used in each panel, reducing both material use and heat loss associated with having more studs.
A pre-compressed, durable foam gasket can be used to seal the sheathing to the wall panel frame, significantly reducing pathways for air leakage.
The gap between the double 2x10 headers at the top of each wall panel can be filled with recycled insulation.
One inch of rigid foam insulation can be applied to the outside of Deltec wall panels, providing a continuous layer of insulation that greatly reduces heat loss through the wood framing in the walls
For an energy efficient home that performs at the same high level as the most advanced energy efficiency technologies in green building, combine the four options above to create a Deltec Energy Wall. Links to Energy Wall page under products.
Energy modeling completed by Vandemusser Design LLC demonstrates that a Deltec Energy Wall with exterior insulation, advanced framing, and insulated headers, combined with field installed spray foam insulation, obtains a resistance to heat flow (R-value) comparable to a 4" structurally insulated panel. (This study was done on our Energy Wall before we added the additional air-sealing benefits of AirBlock.) Click here to view entire report.
We love our Deltec. It is a wonderful design and is VERY fuel efficient. It was green before green was cool. - Becky A., Greenville, SC
Due to the superior energy efficient design of the Deltec home, all the south facing glass and the active solar power equipment, the home is totally self sufficient. - John J., Telluride, CO
Our Deltec home has exceeded our expectations. It is comfortable inside and looks great outside. We are very happy with the energy efficiency and comfort of this design. - Marianne K., Harrisonburg, VA
Each time the gas company sends out a bill, they include a chart comparing our consumption with their average customer. Always, our consumption is just half of the average. - Ed B., Holcomb, NY
Our past electric bills ranged from $120 to 250. With our 4000 sq. ft. Deltec (around 3 times the size of our old house), our electric bill averages around $120, $130 per month. - Kim M., Magnolia, TX
We love our Deltec home. It is very energy efficient (we have not had a gas bill over $75 this year), spacious, easy to maintain, and incredibly "livable." - Daniel & Lynn W., Wildwood, PA
We have just gone through our first winter and I can't believe how tight this house is, and how it weathers the local winds which are occasionally pretty interesting. - Joseph R., Oakhurst, CA
Using regular windows, floor plan design & sub-tunnels we have such great natural lighting that we almost never need to turn on any lights in the house. - Beth H., Charleston, SC
Even on coldest days in Colorado, our house stays in the low 60s without using the furnace during the day. In the summer it never gets above 75 even if 15 degrees warmer outside. Love my house! - Suzanne M., Buena Vista, CO
Everyone else around us is crying about $500-$600 a month electrical bills and ours was $239.00 last month which is really low for Hawaii. - Keith B., Holualoa, HI
For our new home, we built to the basic Deltec standards…and our Deltec Home earned a HERS score of 34. Our home uses 66% less energy than code-built new homes. We’re very pleased with the energy efficiency. -Barbara P., Richford, VT- - Barbara P., Richford, VT
