How to save on heating and cooling Costs

With Replacement Windows & Doors

Updating and Replacing Your Windows & Doors

Do Your Research

If you decide to replace your windows and doors, you will have to make several decisions about the type of windows or doors you purchase, and the type of replacement you will make.

For windows you will need to decide what features you want in your windows. You will need to decide on the following:

Glazing type (Energy Efficiency)
Gas fills and spacers
Colour
Operation type

Selection Process

In addition to choosing the window type, you also need to consider design, energy use and labeling, warranties, and proper installation.

We offer ENERGY STAR when buying new windows. Each window has an energy performance label from the National Fenestration Rating Council (NFRC).

NFRC ratings are included on all ENERGY STAR certified windows and provide a reliable way to determine a window’s energy properties and compare products. .

Installation

Even the most energy-efficient window must be properly installed to ensure energy efficiency and comfort. Many homeowners will try to install their new windows themselves or by a friend. It’s best to have your windows installed by trained professionals according to manufacturer’s instructions; otherwise, your warranty may be void and it may not be sealed properly. Windows, flashing, and caulking should all be installed according to the manufacturer’s recommendations to perform correctly.

Window Selection Tips

Look for the ENERGY STAR

In colder climates, consider selecting gas-filled windows with low-e coatings to reduce heat loss. In warmer climates, select windows with coatings to reduce heat gain.

Choose a low U-factor for better thermal resistance in colder climates; the U-factor is the rate at which a window conducts non-solar heat flow.

Look for a low solar heat gain. SHGC is a measure of solar radiation admitted through a window. Low SHGCs reduce heat gain in warm climates.

Select windows with low U-factors to maximize energy savings in temperate climates with both cold and hot seasons.

Look for whole-unit U-factors and SHGCs, rather than centre-of-glass U-factors and SHGCs. Whole-unit numbers more accurately reflect the energy performance of the entire product.
