Is Your Sliding Door Hurting Your Home's Energy Efficiency?
August 26, 2026
For homeowners across Massachusetts and northern Connecticut, extreme seasonal weather puts home energy efficiency to the test. While most people focus on drafty windows, your sliding glass door is often the hidden culprit driving up monthly utility bills. When seals fail or glass units lose their insulation properties, conditioned air escapes easily.

- Drafts or noticeable temperature drops near the door panel
