Window Materials, Styles & Performance Ratings — Making Informed Choices

Choosing replacement windows involves more than selecting a style. Materials, glazing packages, and performance ratings directly impact durability and efficiency.

Common Window Frame Materials

Homeowners typically consider:

• Vinyl for affordability and low maintenance

• Fiberglass for strength and thermal stability

• Wood or wood-clad for aesthetics and insulation

• Aluminum for modern design with higher conductivity

Each material performs differently depending on climate and exposure.

Glazing & Performance Metrics

Key factors to understand include:

• U-factor (insulation performance)

• Solar Heat Gain Coefficient (SHGC)

• Low-E coatings

• Gas fills between panes

• Impact-rated or sound-reducing glass

The right combination depends on climate, sun exposure, and comfort goals.

How Smart Bids Helps

During the consultation, Smart Bids helps homeowners understand which materials and performance levels make sense for their home. Contractor bids are negotiated to reflect appropriate product selections, allowing homeowners to compare real performance benefits side by side.
