Insulation Technology for Passive Houses

Passive House construction begins with a great insulation. Expanded Polystyrene is the insulation of choice as it provides the most cost effective way to achieve high energy efficient goals. Plymouth Foam manufacturers many products that are designed to work perfectly with the passive design principles.
Passive House Foundation Products
DuraSpec Foundation Insulated
DuraSpec Foundation Insulation is high density Expanded Polystyrene (EPS) foam that is designed to offer good R-Value and provide a drainage plain . Plymouth Foam’s High Density (HD) EPS foam provides good durability and compressive strength against backfilling. See EPS Myths Strength DuraSpec offers a stable R-value, dimensional stability, excellent water resistants and can be engineered to meet almost all specifications.

Gold-Wall Insulation
Gold-Wall Insulation System is made with expanded polystyrene and is unique because it is factory-made with 25 gauge galvanized (G-60) steel studs embedded directly into the insulation. The ridged studs stay flush to the front of the sheet and are laminated on both side with a durable polymeric facer. This system creates a monolithic insulation system that does not allow thermal bridging. Learn More
GEOFOAM for Passive Houses
Make an Unbuildable Site Buildable
Stacks Image 1162097
Site conditions such as weather, poor access, and/or harsh terrain can add cost to a project by creating longer build timelines as well as job delays. Geofoam may not be as materially as cheap as dirt or some other fills, but it is most often quicker to install and easier to move. This speed and ease of Geofoam can reduce labor cost and reduce equipment moving cost which makes a project less expensive overall.

There are numerous ways that Geofoam can reduce cost:
  • Geofoam does not have to be compacted
  • Compared to other fills Geofoam can be placed quickly without the use of large equipment
  • Delivery costs are reduced as 1 truck of Geofoam equates to 12 truck of other fills
  • Not expensive or time consuming form needed as Geofoam can have materials used direct on or next to it
  • Many case less material to be removed in using Geofoam
  • Possibly reduce the amount or thickness of concrete used
  • Less expensive structural utility products could be used with less loading
  • Less settlement can decrease call backs or maintenance costs
See how the Chicago Museum of Science and Industry used DuraFill Geofoam for their submarine exhibit and reduced construction costs.
