Faulty windows are mostly to blame for drafts. While simple repairs can sometimes solve the issue, in other cases the only solution is to replace the windows completely, especially if they are nearing the end of their lifespan and are showing signs of extensive damage. In this blog, local windows replacement contractor Renewal by Andersen® of Cape Cod takes a look at the four reasons why window drafts occur.
1. Worn-Out Weatherstripping
Thanks to manufacturing innovations, today’s replacement windows are more airtight than ever before. However, the weatherstripping that keeps the elements from entering your home may fail eventually. Replacing worn-out weatherstripping may be all that’s needed to eliminate drafts.
2. Frame Cracks
Certain window frame materials expand and contract with temperature changes. Vinyl, for instance, is likely to crack and bow because of these fluctuations. The frames of our replacement windows are made of Fibrex®, a composite material that combines the rigidity and strength of wood and the low-maintenance qualities of vinyl.
3. Poor Installation
Some contractors utilize substandard tools and equipment when installing windows. They use low-quality caulk and other materials to seal the gaps between the windows and your home’s openings. Because windows tend to last longer than the seals, cool air can penetrate and enter indoors through the gaps and cracks in the caulk.
4. Bad Design
Replacement windows have air leakage (AL) ratings that indicate how likely they are to let air into homes. Units that aren’t designed to the right specifications might have higher ratings, which means they’re not as airtight as those with lower ratings.
