How to insulate sliding glass doors.
We have a sliding glass door in our kitchen.
Hubby cut two pieces of tongue and groove insulation board 1 1 2 thick 1 1 2 thick was what we had around the house to fit the opening so that it goes inside the frame snug.
The sliding doors have small wheels on them that fit on a track in the unit.
Vacuum away any pebbles or larger debris.
The simplest and easiest way to keep your sliding glass door from leaking is by keeping the track and rollers clean.
The panel should sit on the floor and extend above the top of the door frame.
If your sliding glass doors run on a track keep the track clean.
If rocks gravel and clumps of dirt have fallen into the threshold the door may not be set correctly on the track.
Then we got a sliding door size piece of plastic that had double sided tape to stick it on the frame around the door.
To the masking tape i have four small strips of self sticking velcro.
Remove the sliding doors from the tracks.
The match to the velcro is on the woodwork of the door.
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.
Use a rag dipped in warm water to remove any dirt from the bottom of the wheels the window or the track.
Caulk around the edges of the sliding glass doors.
Measure the sliding door and decide how tall and wide to make your insulating panel.
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.
This allows cold air in or air conditioned air out.
When it gets really cold outside we have a piece of heavy duty clear plastic that we hang over our sliding glass door.
Dirt gravel or other debris may prevent the door from sliding and sealing optimally.
Adding a window insulation kit to the paned glass door may or may prove to not make a huge difference in my home s ability to conserve heat but i m optimistic.
