Energy-efficient Windows

Beautifully crafted, energy-efficient windows save you money on utility bills, reduce condensation, decrease outside noise, protect furniture from sun damage, and provide improved temperature regulation during summer and winter.

What are the Benefits?

Improved temperature regulation throughout the year, keeping you cooler in the summer and warmer in the winter.

Double (or triple) pane windows better insulate your home from exterior noise.

Furniture, flooring, and art is protected from harmful UV radiation.

Efficient, quality windows improve the aesthetics and increase the value of your home.

Lower utility bills through energy savings.

How does it Work?

The following advances in technology mean that energy-efficient windows are more efficient than ever:

  • Low-emissivity (low-E) coating reduces the ability of heat to pass through them preventing heat from escaping your home in the winter and keeping cooler air in your home in the summer.
  • Double or triple glazing improves efficiency while reducing exterior noise.
  • Inert argon gas between the window panes prevents heat transfer and minimizes condensation.
  • Insulated spacers and frames also prevent heat loss.

What are the Costs?

Energy-efficient windows may cost more than standard windows but they are much more efficient, will enhance your home comfort and can increase the resale value of your home. Prices vary greatly based on the number of windows required, size, type, material, warranty, quality of installation and manufacturer.

The Right System for Your Home

Getting optimal performance from energy-efficient windows depends on more than just choosing the right type and style of window.

Ask your builder, renovator, or energy advisor how this feature could transform your home.

Look for high-efficient, low-e coated windows with a U-Factor at or below 1.22 (W/m2-K) to ensure a quality product and to access rebates.

The quality of the installation can have an enormous effect on window performance and home comfort. Hire experienced and professional contractors to ensure the best possible installation.

Similar to servicing a vehicle, preventive maintenance is a good investment to minimize future problems. Undertake a thorough inspection of all window components (glass, frames and seals) every season looking for any signs of damage or condensation. Keep windows and surrounding wall areas clean. Consult the owner’s manual and ask the installer for details.
