How to Winterize a Sliding Glass Door

Is your sliding glass door more like an open invitation for the cold air to make itself at home? As winter approaches, the drafts from your door frame not only invite the chill in but also send your heating bills skyrocketing. If you’re dealing with inefficient sliding glass doors, you’re not alone. Fortunately, Apex Window Werks has your back. With our vast experience in the field, we’ll guide you through a comprehensive DIY checklist for insulating sliding glass doors. Use these steps to create an inviting, energy-efficient space in no time.

#1. Give Your Sliding Door Tracks a Thorough Clean-Up

Before you can even think about sealing a sliding glass door to fend off winter drafts, it’s imperative to ensure that the sliding door tracks are immaculately clean. Debris, dust, and even small pebbles can settle into the tracks over time and affect the sliding door’s ability to fully close, and therefore, its insulating properties.

#2. Plugging the Gaps and Sealing the Cracks in the Door Frame

Insulation for a sliding patio door isn’t just about keeping the cold air out; it’s also about trapping the warmer air inside. Examine your sliding glass door frame and sliding door casing for any gaps and cracks that allow air to escape. Using high-quality caulk to seal these areas can be a simple yet effective procedure that could make a world of difference.

#3. Revitalize the Weather Stripping

Weatherstripping ages just like everything else. When was the last time you checked yours? Old or damaged weatherstripping needs to be replaced to maintain an energy-efficient home. There are various types of weatherstripping on the market, but for sliding glass doors, we typically recommend adhesive-backed V-strip.

#4. Swap Out Your Regular Curtains for Thermal Insulating Curtains

If you’re looking for an additional tip to kick up your insulation game, consider trading in your current curtains for thermal insulating curtains. These are specialty curtains that can significantly enhance the thermal performance of your sliding patio doors, and they offer another layer of protection against the elements.

#5. Embrace the Benefits of Plastic Film

The plastic film acts as an extra layer of insulation for sliding glass doors, reducing heat transfer through the glass. For insulating a sliding glass door, you can apply this film yourself; it adheres to the window due to the static charge between the sliding glass and the plastic.

#6. Install Fin Seal or Brush Fin Weatherstripping

For the vertical sides of the door frame, fin seal or brush seal weatherstripping can be extremely effective. These types of weatherstripping serve as a barrier that adapts to the sliding doors’ natural movement and provides a superior seal against the cold air.

#7. Wrap It Up with a Window Film Insulation Kit

If you’re searching for a comprehensive solution to insulating your sliding patio doors, a window film insulation kit could be the game-changer you need. These kits typically include everything required to insulate your sliding glass doors, from adhesive or magnetic tape to plastic sheets. The insulation film basically acts as an additional barrier and keeps the cool air out and the warm air securely within your home.

Insulate Sliding Glass Doors by Professionals vs. DIY

When it comes to insulating sliding glass doors, you have two options: DIY or hiring professionals. DIY methods can be cost-effective and give you the satisfaction of tackling the project yourself. Basic tasks can be done with a simple trip to the hardware store, for example, to check weatherstripping, add fin seal, etc.

However, hiring door repair professionals like those at Apex Window Werks offers the advantage of expertise and precision. Not only will our team assess your door’s condition and identify key areas that require attention, but we can also provide advanced solutions like replacing your old glass panels with tempered energy-efficient glass. This offers a more durable and long-lasting barrier against the elements. Your home will stay comfortable and energy-efficient year-round.
