Frequently Asked Questions
What building materials have the biggest impact on energy efficiency?
Windows and doors have the biggest impact, accounting for 25-30% of home energy loss. High-performance windows with Low-E glass and proper insulation can dramatically reduce heating and cooling costs. Insulated siding, proper weather sealing, and efficient HVAC systems also make significant impacts.
Are energy-efficient materials worth the extra cost?
Yes, energy-efficient materials typically pay for themselves within 5-10 years through reduced utility bills. For example, ENERGY STAR windows can save $126-$465 annually on energy bills. Many energy-efficient upgrades also qualify for federal tax credits and Georgia Power rebates.
What R-value insulation do I need in Atlanta?
Atlanta is in Climate Zone 3. The Department of Energy recommends R-38 to R-60 for attics, R-13 to R-15 for walls, and R-25 for floors over unconditioned spaces. Proper insulation is crucial for both summer cooling and winter heating efficiency in Georgia.
Do you carry ENERGY STAR certified products?
Yes, Randall Brothers carries ENERGY STAR certified windows from brands like Sierra Pacific, Lincoln, and ViWinTech, as well as other energy-efficient building materials. Our staff can help you identify products that meet ENERGY STAR requirements for federal tax credits.
