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.
Thermal insulation windows and doors.
Most modern glass doors with metal frames have a thermal break which is a plastic insulator between inner and outer parts of the frame.
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.
Glass or patio doors especially sliding glass doors lose much more heat than other types of doors because glass is a very poor insulator.
Thermal windows have panes of glass that are separated by a insulated gas filled gap.
U value usually expressed in w m2k watts per square metre per degree kelvin and describe the heat transfer in watts through a square metre of a building element such as a wall floor or roof.
This insulating gas reduces the amount of heat that is transferred between the interior and exterior of your home or business.
This keeps the cold air out with a pocket of air between the window and the plastic.
It s a great insulator and perhaps the best cost effective way to insulate your windows.
Window insulation kits are also virtually invisible so you can add it to any window in your home.
