Our team takes an active role in finding progressive products, such as fibreglass and sustainable wood doors to lessen environmental impact. Many of the products we carry are also Energy Star-certified and maintain a high level of energy efficiency, while adding to the beauty, functionality, and durability of your home.

We have found that energy efficient front doors and exterior doors can have a beneficial effect on your lifestyle and your home, by ensuring that you can maintain a minimal impact on the environment, achieve long-term performance, and increase energy cost savings.


Front doors, exterior doors, and even interior doors are some of the most important features affecting the comfort and energy efficiency of your home. Doors tend to be the largest openings in a building, and are crucial to ventilation, lighting, and comfort.

Old, leaky, or failing doors account for a large portion of wasted energy in buildings. In winter, warm air leaking out around the cracks in the door or under your doors means more energy is required to heat your home, resulting in higher utility bills. In the summer, cool air will escape in the same way, increasing your air conditioning costs.

The performance of a door is affected by three main factors: air, heat, and solar radiation.

  1. Air flow through a closed door that leaks will decreases energy efficiency.
  2. Heat moves from a warmer area to a cooler area naturally. The purpose of a properly functioning door is to minimize the heat transfer occurring between different parts of your home.
  3. Solar radiation from sunlight can pass through the glass of a front door and warm the air inside a building. This is beneficial in winter, as this natural heating can help to reduce your energy costs. In summer, it is desirable to reflect as much of the solar radiation as possible back outside.

Various parts of doors work together to control air, heat, and solar radiation, minimizing the impact of external weather conditions on the temperature of the interior of your home.


Energy Star® is a federal program that determines where a variety of products, including front doors, exterior doors, and interior doors, meet certain energy efficiency standards. Products that achieve specific benchmarks can display the Energy Star label.

Bavarian Window Works is a registered Energy Star company and offers an extensive roster of products and options that meet Energy Star standards from our showroom in Kitchener. With doors, the Energy Star standards will vary by climate.
