How to Install Thermal Windows
For handy homeowners, installing thermal windows can save a significant amount of money on heating and cooling costs. What is the difference between thermal windows and traditional windows? Thermal windows feature double- or triple-panes, while traditional windows are single-paned.
Typically, today's thermal windows deliver two-to-four times more energy efficiency than single pane windows, which means many homeowners could see a 20 percent to 30 percent drop in their winter heating bills. Another advantage is that vinyl thermal windows can eliminate the extra step of painting.
Here is a quick overview of how to install thermal windows:
Installing Thermal Windows in 10 Steps
- Measure the regular window at top and bottom for the width, and at both sides for the height dimensions.
- Remove the old single-pane window.
- Take care to gently remove the trim and the upper and lower stops.
- Gently place the thermal window in the opening, making sure you know which side should face outside and which should face inside.
- Once the window is secure in the opening, shim it on all sides, making sure it is level and plumb.
- Use the screws provided by the manufacturer to secure the window in place. Be sure not to over-tighten the screws to avoid warping the frame.
- Open and close the window to check if it works properly.
- Nail the wood back around the window and install the old trim.
- Then use caulk to seal the exterior gap between the new thermal window and the window opening.
- Use glass cleaner and a soft cloth to clean the window.
If you follow the manufacturer's instructions on how to install thermal windows, you should be able to do it without problems.
