Energy Star - Highly Efficient Windows

Energy Star certified windows are designed to be more energy efficient than traditional windows. In addition to saving money on energy bills, they can also help to reduce your home’s carbon footprint.

Energy Star certified windows help to keep your home cooler in the summer and warmer in the winter, making it more comfortable for you and your family.

Vinyl windows experts

Vinyl Windows Ajax

Vinyl is a durable material that is not susceptible to warping or rotting like wood, and it requires little maintenance. They are also available in a variety of colours and styles to suit any home. Are you preparing to sell your property? Consider vinyl windows to increase the value of your home. These windows offer a great combination of beauty, durability, and energy efficiency, making them an excellent choice for home and property owners.

triple pane windows

Triple Glass Ajax

Triple glass windows are a type of window that consists of three panes of glass. Argon is used instead of air in the internal cavity of the glass units. Argon is an odourless, inert, safe gas that is denser than air. As a result, triple glazed windows provide reduced inter-pane convection and improve thermal insulation efficiency.

Triple pane windows are also generally thicker than single- or double-paned windows, which makes them more resistant to breakage. So if you're noticing drafts in your home, consider triple glass windows as they offer a number of benefits, including improved energy efficiency, increased sound insulation, and enhanced security.

window colour options

Colour Options

When it comes to choosing vinyl windows, there are a wide variety of colours available on the market. White is the most popular and affordable colour choice for vinyl windows, as it provides a clean and classic look. However, other popular colour choices include beige, brown, and grey.

There are also a wide range of darker colours available, such as black and navy blue. These darker colours can provide a more dramatic look for your home.

easy maintenance windows

Easy Maintenance

When it comes to easy maintenance windows, vinyl windows are some of the easiest to care for. Unlike wood windows, they don't require painting or staining, and they're also resistant to rot, warping, and insect damage.

These windows are designed to be weather-tight, so they won't let in drafts or leaks. As a result, you can expect your vinyl windows to provide years of trouble-free service with minimal upkeep.

Yes, in Ajax, you typically need a permit to replace windows in your home. The City of Ajax requires building permits for any work that involves structural changes or alterations to a building, including window replacements. This is because replacing windows can impact the structure of the building and may require changes to the framing, insulation, or other aspects of the wall surrounding the window.

Do you suspect your windows and doors in Ajax may need to be replaced? Here are some surefire signs that they might need an upgrade:

  1. Drafts: Cold drafts around your windows and doors can be a sign that the seals are wearing out, and replacement is necessary. If you feel even the slightest chilly breeze around the area, it may be time to consider investing in new windows and doors.
