- Leak-resistant framing
- Controlled ventilation features
When properly installed, skylights reduce daytime electricity usage while maintaining temperature control.
Placement and orientation play an important role in maximizing their performance benefits.
Add Exterior Shading Elements
Solar heat gain through windows contributes heavily to indoor temperature increases during warmer months.
Exterior shading solutions help control this effect.
Examples include:
- Window awnings
- Pergolas
- Adjustable louvers
- Exterior shutters
- Covered patios
These features reduce direct sunlight exposure while still allowing natural daylight indoors.
Shading elements also enhance exterior aesthetics and improve outdoor usability.
Install Energy-Efficient Garage Doors
Garages attached to homes often become hidden sources of heat transfer.
Upgrading to insulated garage doors helps:
- Maintain indoor temperature stability
