Why Window Seals Matter

A window seal-- typically a flexible strip of rubber, vinyl, foam, or silicone-- develops a tight barrier in between the window frame and the sash. When the seal is undamaged, it:

• Prevents air leakage, minimizing cooling and heating expenses.
• Blocks water and moisture that could trigger mold, rot, or paint damage.
• Keeps out dust, pollen, and noise, contributing to indoor air quality and peace.
• Safeguards the window's structural elements from UV‑induced wear and tear.

When the seal fails, all of these benefits are jeopardized, frequently resulting in visible discomfort and higher energy expenses.

• Visible cracks, spaces, or shrinkage in the seal product.
