How Do Windows & Doors Affect Energy Efficiency?

When it comes to improving the energy efficiency of a home, most people think about insulation, HVAC systems, or even renewable energy sources. However, windows and doors play a pivotal role in determining how energy-efficient your home truly is.

Here’s how these essential architectural features impact energy efficiency and what you can do to optimize their performance.

How to Improve Energy Efficiency with Windows and Doors

Upgrade to energy-efficient windows and doors: Look for products certified by Energy Star or similar programs.
Seal gaps and cracks: Use weather stripping, caulking, or foam sealants to minimize air leaks.
Install window treatments: Use blinds, shades, or films to regulate indoor temperatures.
Double-glazing or secondary glazing: These options add an insulating layer to existing windows.

Benefits of Windows and Doors

Cavity wall insulation is an effective way to improve your home’s energy efficiency by reducing heat loss through the walls. Cavity wall insulation provides several advantages:

Heat Loss and Gain

Poorly insulated windows and doors with gaps or cracks cause heat loss in winter and heat gain in summer, increasing energy costs.

Air Leakage

Improperly sealed windows and doors can create drafts, allowing conditioned air to escape and outside air to enter.

Solar Heat Gain

Poorly insulated windows cause overheating, while energy-efficient Low-E windows control solar heat gain for comfort.

Insulation Properties

Energy-efficient windows and doors reduce heat transfer, unlike older single-glazed options with poor insulation.

Lower Energy Bill

Energy-efficient windows and doors cut energy costs by stabilizing indoor temperatures.

Daylighting

Large windows save energy with natural light but require shading to prevent heat gain.

Increase Resale Value

Energy-efficient windows and doors increase resale value by offering long-term savings.

Increase Comfort

Energy-efficient windows and doors keep indoor comfort year-round by blocking heat loss and gain.
