Twenty-year-old windows are often nearing the end of their typical 15–25 year lifespan and, while they may still function, they are likely less energy-efficient than modern alternatives. If they are wood-framed, vinyl, or showing signs of damage, upgrading usually offers significant benefits in energy savings, comfort, and noise reduction.
Common Mistakes to Avoid. Using the Wrong Mortar: Regular masonry mortar will not bond well with glass blocks or provide the necessary strength.
To keep the cold out, apply a clear window insulation shrink film directly to the frame to block drafts. For structural gaps, use adhesive weatherstripping. Cover with heavy thermal curtains for an extra layer of insulation.
