Helpful guides and industry resources for homeowners planning windows, doors, and siding projects
Energy Efficiency Guides
Understanding energy efficiency is crucial when selecting windows, doors, and siding for your Pacific Northwest home. These are the resources I found most helpful when researching our own window and door projects.
Window Replacement Fundamentals
The U.S. Department of Energy provides comprehensive guidance on window replacement. Their research shows that heat gain and loss through windows accounts for 25-30% of residential heating and cooling energy use. This makes window replacement one of the most impactful home improvements you can make.
- Energy consumption facts
- R-value and U-factor ratings
- Climate-specific recommendations
- Cost-benefit analysis
Certified Products & Standards
The ENERGY STAR program certifies high-performance windows, doors, and skylights. Products with ENERGY STAR certification deliver approximately 13% average energy savings compared to single-pane windows. This is essential information when evaluating product options.
- Product certification standards
- Climate zone comparisons
- Savings calculators
- Product finder tool
Performance Ratings
The National Fenestration Rating Council (NFRC) provides standardized performance ratings for windows and doors. NFRC labels show U-factor, SHGC (Solar Heat Gain Coefficient), and visible transmittance (VT) ratings—the industry standard for evaluating and comparing products.

- Contractor Qualifications: Look for licensed, insured, certified professionals with warranty coverage
- Timeline Planning: Schedule projects during favorable weather windows for optimal installation conditions
Evaluating Proposals
- Product Specifications: Verify that proposed products match your research (U-factors, SHGC ratings, certifications)
- Installation Methods: Professional installation should include proper flashing, sealing, and insulation for optimal performance
- Warranty Coverage: Compare manufacturer warranties on products with workmanship guarantees from the contractor
- Payment Terms: Reputable contractors typically require deposits with progress payments, not full payment upfront
Common Questions Answered
How much can I save with energy-efficient windows?
According to ENERGY STAR, replacing single-pane windows with ENERGY STAR certified products typically saves about 13% on annual energy costs. This varies by climate zone, current window condition, and your specific heating/cooling usage patterns.
What’s the best time to replace windows?
Spring and fall offer ideal weather conditions for professional window installation. Summer heat and winter cold can affect installation quality. Plan your project during these favorable seasons for optimal results.
Should I compare NFRC ratings?
Absolutely. NFRC labels provide standardized, third-party tested ratings. Compare U-factors (lower is better for insulation), SHGC values (important for solar control), and visible transmittance (VT) across different products to make informed choices.
How important is professional installation?
Critical. Professional installation ensures proper sealing, flashing, and insulation—which directly impacts energy performance, water infiltration prevention, and longevity. Poor installation can negate the benefits of premium products.
