Save Energy! Save Money! Save Planets!

Energy Efficient Wall and Insulation Systems:

Really, what all this green building stuff should be focused on is CONSERVING ENERGY! The remaining parts of the green building standards should be considered basic code requirements and basic standards of care. The real focus should be on energy conservation. That's why we created our exclusive EnergyLock™ Building Systems: EnergyLog™, EnergyPanel™, EnergySIP™.

1. EnergyPanel™:

Our most popular EnergyLock™ Building System is the EnergyPanel™. This is basically a factory pre-built wood-stick-framed wall system, but with highly efficient components. The first line of defense with the EnergyPanel™ wall systems from Natural Element Homes is the Huber ZIP System wall and roof sheathing. The Zip system eliminates the need for house wrap and roofing felt with its impregnated outer layer. ZIP tape seals all joints and prevents air infiltration.


EnergyPanel™ Wall Systems are factory pre-built for maximum efficiency.

Combine the above ZIP system with the below insulation systems for a super efficient home.

There are several insulation systems available for use with the EnergyPanel™ Wall Systems from Natural Element Homes. Here are a few videos showing installation of the more popular insulation options.

2. EnergySIP™:

We also build with our EnergySIP™ wall system. SIP's (Structural Insulated Panels) provide maximum thermal performance with R-values up to R50. SIP's are factory pre-cut for easy assmebly.

3. EnergyLOG™:

Log Walls are America's original building system. Today's log wall systems can be precision milled and factory pre-cut for easy assembly and high performance. We offer solid wood logs and our EnergyLOG™ system for extreme cold climates. The EnergyLOG™ features a solid foam core center for R-values up to R-32. The EnergyLOG™ comes in many shapes and sizes with various methods of corner joinery (dovetail, saddle notch, butt-and-pass, corner post) and a combination of wood species in the same log (e.g. cedar outside, pine inside).
