Spray Foam Attic Insulation

Spray Foam Insulation for Attic Spaces

Spray Polyurethane Foam Insulation can be used in two common ways to insulate your attic space and protect your home from other weather and moisture related damages. At Hovis Custom Builders, we use the LATEST technologies in building science.

Traditional vs. New Technology Building Science
Traditional - Vented Attic
  • Attic floor is insulated with fiberglass or cellulose between floor joists
  • Rest of attic left un-insulated
  • Attic is insulated through gable, soffit, and ridge vents in roof structure
  • Attic temperatures can reach to over 140 degrees in the summer
  • Conditions produce severe energy loads for your air-conditioner and duct work causing DECREASED energy efficiency
New Technology - Un-Vented Attic
  • Spray foam is sprayed directly to underside of roof between the joists, around rim, soffit areas, and gable wall ends
  • Effectively seals off entire attic space from air infiltration
  • Attic now becomes “quasi-conditioned” space with comfortable temperatures
  • Greatly reduces energy loads on air condtioner and duct work leading to INCREASED energy efficiency
Benefits Of Including Attic Insulation
  • Duct leakage and heat loss/gain from ducts is much less of an issue.
  • Air sealing is easier in the roof that in the ceiling.
  • Dust and loose insulation are less likely to migrate down to the living space.
  • Tests show energy costs are significantly lower when the attic is sealed.
Foam Insulation Benefits
  • Stops air and moisture infiltration
  • Makes your home more comfortable
  • Saves on energy costs
  • Adds strength to the building structure
  • It is permanent and will not sag
  • Keeps dust and pollen out
  • Improves air quality
  • Reduces capacity requirements, maintenance and wear of HVAC equipment
  • Meets all building codes
