Check my meetup site for local events, Triangle Green Homes Meetup.
This month we visited a construction site to learn about insulated concrete forms (ICF). Bradley Yoder of Carolina XWalls (formerly Triangle PolySteel) graciously offered to give us a talk at the site in Cary that was using his product. Bradley is a long time member of the Green Home Builders of the Triangle and the Durham Orange County Home Builders Association. He’s a strong advocate for green building and a good buddy for coming out for us on Wednesday.
ICFs can be used for foundations or the entire structure. The resulting concrete becomes a large mass that is very disaster resistant and energy efficient. Homes constructed with ICFs are extremely energy efficient and comfortable structures.
Some of the benefits of ICF construction:
* Energy Savings
* Disaster resistance
* comfort and safety
* peace and quiet
* ecological responsibility
* low insurance costs
* moisture management
* Low maintenance
* strength and longevity
Superior Walls are similar in that they are cast concrete and insulated on one side. The technique is faster than the poured construction for ICFs. However, they are about half as effective as ICFS as the poured concrete slabs have half the insulation.
Regardless of which one, both are more efficient foundations that traditional blocks and the result is less energy used to heat and cool homes!
