Insulating Around A Sliding Glass Door

Glass or patio doors especially sliding glass doors lose much more heat than other types of doors because glass is a very poor insulator.

Insulating around a sliding glass door.

Insulated drapes blackout curtains or cellular blinds are just some of the products that can be used to reduce energy loss through your sliding glass doors. Measure the sliding window and determine the size of the insulating panel which should cover the top of the door frame down to the floor area. The simplest and easiest way to keep your sliding glass door from leaking is by keeping the track and rollers clean. Double glazed inserts can be installed to existing sliding doors.

When debris gets trapped in this track or on the wheels it can cause holes in the natural insulation of the sliding doors. I cut it to fit the door and put a border of masking tape across the top of the plastic. Installing insulation over the stationary glass panel and weatherstripping between the insulation and the sliding glass door effectively seals the sliding glass door from the inside. Watch this video to see how to do it.

It should go over the window side and the size should be enough to cover the whole window. Use a rag dipped in warm water to remove any dirt from the bottom of the wheels the window or the track. Remove the sliding doors from the tracks. To the masking tape i have four small strips of self sticking velcro.

Measure the sliding door and decide how tall and wide to make your insulating panel. The match to the velcro is on the woodwork of the door. Dirt gravel or other debris may prevent the door from sliding and sealing optimally. To achieve the greatest efficiency i ve read that the insulation should be 1 from the glazing on the glass and by my measurements the glass panes do sit in the middle of our heavy 2 wooden door.

It should extend beyond the side of the window and either be wide enough to cover the entire door or stop where the door starts and just cover the non opening part of it. Replace existing curtains with insulating thermal curtains. The insulating panel should be cut to the appropriate measurement taken. Most modern glass doors with metal frames have a thermal break which is a plastic insulator between inner and outer parts of the frame.

When it gets really cold outside we have a piece of heavy duty clear plastic that we hang over our sliding glass door. You ve installed patio link pet door insert and now its time to install a weather seal inside your glass sliding door. The panel should sit on the floor and extend above the top of the door frame.
