Air Sealing

Effective air sealing is essential to prevent air leakage around windows, which can lead to drafts, energy loss, and reduced comfort. Here's why air sealing is crucial:

  • Energy Efficiency: Air leaks can significantly impact the energy efficiency of windows. Gaps and cracks around the window frame allow conditioned air to escape and outdoor air to infiltrate, leading to energy loss and increased heating or cooling demands.
  • Comfort: Air leaks can create drafts near windows, causing discomfort and temperature inconsistencies within the living space. Proper air sealing helps maintain consistent indoor temperatures and eliminates drafts.

To ensure proper air sealing during installation:

  • Apply weatherstripping or caulking around the window frame to seal any gaps or cracks.
  • Use a quality sealant to seal joints and connections between the window frame and the wall.
  • Verify that all areas around the window are properly sealed, including the perimeter, corners, and meeting points.


Insulation plays a critical role in minimizing heat transfer and enhancing the energy efficiency of windows. It helps maintain desired indoor temperatures by preventing heat gain in summer and heat loss in winter. Here's why insulation is vital:

  • Thermal Performance: Proper insulation around windows minimizes thermal bridging, which occurs when heat transfers through the window frame and affects its overall efficiency. Insulation reduces heat transfer and helps maintain the desired indoor temperature.
  • Condensation Control: Insulation also helps prevent condensation by maintaining consistent surface temperatures around windows, reducing the risk of moisture-related issues such as mold and mildew growth.

Expert Buying Advice

To ensure proper insulation during installation:

  • Use insulation materials designed for windows, such as expanding foam or fiberglass batts.
  • Insulate the gaps and spaces around the window frame, including the area between the window frame and rough opening.
  • Verify that the insulation is properly installed and fills the entire space without gaps or compression.
