How do they work?
Window warmers are made from a clear plastic film which can be cut to the size of the window frame. The pack includes an adhesive tape to which the plastic is fixed. Once a good seal is established around the window frame a hair dryer is used to blow hot air onto the plastic. The plastic shrinks, producing a film which is as tight as a drum. It is almost invisible from 2 metres and totally invisible from 3 metres.
You will enjoy a warmer room, no condensation and there's no window sill for dust and debris to collect.
A great bargain!
Note: Window warmers cannot be fitted to aluminium joinery.

Installation Guide
Use a steel tape measure to measure the length of your frame on both sides of the door / window and across the top.
Cut the plastic V-seal to the appropriate length with scissors.
Remove a couple of inches of the paper liner and position it into place at the top of the door / window frame so that the bottom of the V-shape will point inward toward the house.
As you bring the plastic down, simultaneously pull off the paper backing and press it into place. If you get it slightly out of line, simply pull it back up. The V-seal will adhere again when you press it back into position.
Run the V-seal all the way down to the bottom of the door frame. Do the same on the opposite side of the frame and at the top.
Now fold the plastic strip along its pre-scored center so that the V will protrude into the space you are trying to seal. Do this all the way around the door / window .
Be sure the door / window does not fit too tightly on the top or along the hinge side before installing the weatherstripping. You may need to plane and/or sand the surface a bit for a smoother fit.
