Doing More With Less

Synopsis

• Eliminated need for attic floor insulation entirely
• Noticeable noise reduction
• Comfortable temperature even with frequent door-opening and hundreds of guests at only 60% AC capacity

Background

The dotCOM dreamHOME (dCdH) is the first of its kind Internet-driven home building project/experiment to be featured developed, and constructed online from concept to completion. Icynene participated by providing the polyicynene soft foam spray insulation. The home was constructed in Las Vegas using insulated concrete forms for the wall and a standard wood roof assembly.

Results

By using Icynene^® spray insulation, the builders of the dreamHOME were able to eliminate insulating the attic floor entirely. Instead, they had the material spray-applied to the underside of the roof deck. By insulating the roof plane with Icynene, any cooling losses from the HVAC system/ducts located in the attic were kept within the thermal envelope of the house.

Once the home was insulated, many of the trades still working in the home commented on how quiet and cool the house was, even during the middle of the day. During the grand opening reception, full electrical power was not available to the home. With only 60% of the air conditioning operational, the home remained cool and comfortable in spite of the hundreds of guests and constant door opening.
