Sliding Door 'Draft Stopper' Center Post Weatherstrip

Also known as 'Center Post Weather Strip,' this adhesive strip will seal the drafty gap created between stationary and sliding glass doors when a panel pet door is installed. Some customers use two—one at each end of the gap—for an even better seal. The adhesive strip is 1/2" wide and begins inset 1/8"—overall width is 1 7/ 8". This energy-saving product is included in all Thermo Panel 3e, Quick Panel 3, and Thermo Panel 2e Microchip patio panels.

Installation Instructions

Step 1: Clean the area with rubbing alcohol where you are going to apply the draft stopper. This will allow it to adhere better.

Step 2: You can put the draft stopper on the back edge of the sliding panel, or if your sliding door is on the outermost track, you can put it on the front edge of the stationary panel. We recommend your draft stopper is installed inside and not on the outside where the weather can cause it to fail. If it is too wide, you can trim it, but be careful that the line is even, or else you will have gaps where air can get in. Also, you want the edge of the weather seal of the draft sealer to just barely kiss the glass. If you overlap, it will wear down the adhesive and will not stick for long.

Step 3: Start at the top, and as you are unrolling it, peel the covering off the self-adhesive as you work your way down. This method allows you to have more control to get a straighter installation of the adhesive backing.

Step 4: When you get to the door bottom, trim off any excess. Make sure there is no under-door draft blocker that will prevent you from opening and closing your door.

Note: Depending on the top and bottom tracks in order to get it to go the full length of the slider you might need to notch out small sections for it to fit inside the rails to completely cover the slider.
