How to Insulate Patio Doors in 5 Effective Ways

Patio doors are an ideal doorway since they allow in the morning light, creating a more open atmosphere until temperatures drop. It is no surprise to many homeowners that patio glass doors can be a significant source of heat loss.

Because glass is a poor insulator, it isn’t easy to maintain a comfortable indoor temperature. Furthermore, patio doors give numerous escape routes for the heat within your home. As a result, the area around your patio door is frequently drafty.

As the fall season fades and the winter season approaches, you begin to worry about how to keep your family warm, and knowing how to insulate patio doors is one way to do so.

Here are some ideas for insulating a patio door.            

How to Insulate Patio Doors

1. Keep the door track clean

Imagine a house with open doors during winter, and you might be better off by pitching a tent outside, right.

Well, if you have a patio door running on sliding tracks and you don’t clean the tracks channels regularly, be sure that your door won’t close properly. 

Patio doors are prone to lots of debris since they are outside, and if you don’t clean them, the debris will accumulate.

I used to clean mine every week until I was shocked with the amount of debris it was packing after a week and decided to give it special cleaning every three days.

Depending on the foot traffic you have on your patio, decide how many times you should clean your door tracks to keep it functional.

Furthermore, sweeping your patio door tracks won’t take long. However, I would recommend vacuuming it. Use a vacuum with a header that will fit in the slider channels to effectively remove even the tiny sand particles that will make your door not seal properly.

2. Add or replace old Weather Stripping 

A squishy lining attached to your door’s jamb is the weather stripping.

Weather Stripping plays an important role on our patio doors, and they help minimize the loss of warm air by ensuring there are no gaps between sliding glass doors. They also keep snow and rain out of our home.

However, this black rubber substance wears out and needs replacement. Inspect your door frame to see if there is any that needs replacement.

When you see the light passing through the frame, that indicates your weather Stripping is worn out. They are different varieties of Weather Stripping to choose from; there is foam tape, felt, V-strip, and tubular silicone.

Weather Stripping is easy to install; pick one that will suit your patio door frame and install it to fix the drafty door.

3. Plastic window kit

Experiencing a harsh winter climate, then this inexpensive temporary fix is the best for you. The plastic window film is designed to increase insulation, and it will make your patio door more energy efficient.

Most people refer to this strategy as old school, but many of us will agree that it is still effective. Plastic insulation uses shrink-wrap that shrinks when exposed to heat, making it easy to install yet messy.

If you can bear the mess, get a crystal-clear film heat shrink to seal out cold and use a hairdryer to seal it.

The plastic sheeting can be cut to fit any patio door regardless of the size. As you heat it, it will shrink and tighten, making your patio door airtight.
