Replacement windows are custom-made to fit inside the existing window opening after the old sash are removed.

Like your home’s insulation and HVAC system, windows and exterior doors play an important role in home energy performance. But windows and doors get extra attention because they also need to look good. When the paint cracks or peels around a window frame or the weatherstripping comes loose around a door, these details detract from a home’s appearance.

Dr. Energy Saver works with many of the most popular window and door manufacturers, and installs top-of-the-line, energy-efficient windows and doors across the country. Our energy technicians will help you identify the best products for your home.

Although they may seem simple in comparison to a furnace, heat pump, or water heater, windows and doors have actually become fairly complex over the last 20 years or so.

If the windows or exterior doors in your house need to be replaced, you’ll soon discover that there are countless options available. A huge number of manufacturers offer an array of different styles.

Materials, energy performance ratings and warranties also vary. And of course, there’s no shortage of contractors ready to bid on your window or door replacement project. Don’t get discouraged by all this information.

Just ahead, we’ll help you understand what’s important when selecting windows and exterior doors.

Exterior doors also need to be attractive, durable and energy efficient

Many of the details explained for windows above also apply to exterior doors. Older, solid-wood exterior doors are often replaced with doors that have fiberglass or steel skins and foam insulation cores. Fiberglass exterior doors are usually considered better for several reasons.

They resist denting and heat transfer better than steel doors. Also, the fiberglass door skin can be textured and stained to resemble a solid wood door.

Homeowners interested in improving comfort and energy efficiency often decide to replace older sliding glass doors with new, more efficient units.

The vinyl frames used on new Sunrise sliding glass doors outperform wood and metal frames used on other “sliders” in terms of durability, energy efficiency and maintenance-free features.

Nick Nason completed an insulation evaluation and upgrade at our condo last winter. As a result of his excellent work our heating costs so far this winter are 50% of what they were last winter at this time, despite much colder conditions. In addition to the financial savings the level of comfort has improved tremendously.
