The Anatomy of an Energy-Efficient Patio Door

When it comes to high-quality patio doors, Renewal by Andersen® of Seattle has plenty of options. Every door we provide is custom made to fit your unique needs and offers unparalleled energy efficiency.

The Anatomy of an Energy-Efficient Patio Door

Here’s a rundown of how our patio doors boost your home’s energy efficiency.

Insulative Frame

Like our replacement windows, our patio doors are built with a Fibrex® frame. This insulating material is made of wood fiber and composites. Designed to be as durable as vinyl, it boasts the beauty of wood.  We are meticulous about taking measurements, ensuring your new door fits your wall opening precisely so there are no gaps in your system.

Low-E Glass

To keep your home protected from UV and infrared rays, patio doors from your Renewal by Andersen window contractors are fitted with our signature Low-E4® glass packages. This high-quality glass has exceptional U-Factor ratings, meaning it helps reduce heat transfer in your home. It also provides excellent visibility and filters out UV light. You can have it tinted to block out over 70% of solar heat.

Durable, High-Performance Weather-Stripping

A durable patio door needs to be able to withstand severe weather. This is why our doors feature tightly sealed weatherstripping, designed to cut off any possible air leakage. This way, there is virtually no chance of air or moisture entering or escaping your doors.

With our replacement patio doors, energy efficiency is at its peak. If you want to customize or install patio doors, don’t settle for anything less than Renewal by Andersen® of Seattle.
