Polyethylene Triple Glazed Window - English

Summary: This solution uses polyethylene, PVC piping, pipe insulation and duct tape, to create 4 layers of insulation. The solution insulates better than double glazed windows.

How it works

This solution is similar to triple glazing. In our case support is provided by a frame made from PVC piping. Around this frame, we wrap a single sheet of polyethylene. We secure this polyethylene using the insulation noodle attached to the frame. We then wrap the outer frame using more polyethylene. This results in a triple-glazed polyethylene sheet. In case you wish to protect against rain and other elements you can strap a sacrificial sheet to the outside of the window.
