Also, air leaks around the doors make things worse. This makes your home less cozy and more expensive to keep warm or cool.
Common issues include:
- Poorly sealed or worn-out weatherstripping
- Inadequate or missing door sweeps
- Single-pane glass or inferior glazing
Benefits of Proper Insulation
Insulating sliding glass doors well can really help. It stops heat from escaping and air from leaking in. This makes your home's temperature more stable and saves you money on energy.
The benefits of proper insulation include:
- Reduced heating and cooling costs
- Enhanced indoor comfort
- Minimized condensation and moisture issues

Assessing Your Sliding Glass Doors
