Why Go Beyond Advance Why Go Beyond Advance Framing?Framing?

Both the builders and home owners can benefit Both the builders and home owners can benefit from advance or new framing techniques. The from advance or new framing techniques. The proposal are structurally sound and come at a proposal are structurally sound and come at a lower cost of materials and labor while lower cost of materials and labor while increasing the R-value of the structure.increasing the R-value of the structure.

““Fully implementing advance framing techniques Fully implementing advance framing techniques can result in materials cost savings of about $500 can result in materials cost savings of about $500 or $1000 (for a 1,200- and 2,400 sq-ft house or $1000 (for a 1,200- and 2,400 sq-ft house respectively), labor savings of between 3 and 5 respectively), labor savings of between 3 and 5 percent and annual heating and cooling savings percent and annual heating and cooling savings of up to 5 percent”of up to 5 percent”
