Things You Need for This Tutorial
Installing a frameless window on an RV is a simple process that requires only a few tools.
First, you will need a replacement RV window that fits squarely on the RV opening. You might want to check with your RV manufacturer if they also sell frameless windows. Alternatively, you can ask for recommendations to simplify and hasten your search.
Second, a screwdriver is essential in loosening old screws and tightening new fasteners. Be mindful of the screw size and type to determine the appropriate screwdriver you need for the project.
Third, window sealing materials are also crucial to form a watertight and airtight connection between the frameless window and your motorhome’s window opening. A silicone rubber sealant and a caulk gun are needed for this.
Fourth, you will also need cleaning materials, such as a scraper, scrub brush, warm soapy water, and clean cloth. A ladder will come in handy, too.
Steps to Installing a Frameless RV Window
Step 1. Take out any window treatment.
Do your RV windows have pleated shades, aluminum blades, rollers, or cellular shades to give you privacy and UV protection? If you do, it would be best to remove them before you proceed with the frameless RV windows replacement.
You will not want any of these window treatments to hinder your work. Moreover, you can damage these window treatments when pushing the old glass out of its slot.
If your RV window does not have these treatments, you can start removing the old RV window.
Step 2. Remove the RV window.
Look at your RV window and check the location of screws that secure it to the RV wall. The screws can be anywhere between size 12 and 20. Ensure to use the correct screwdriver to loosen and remove the fasteners from their slots.
Have someone outside the RV supporting the window as you push it out of its frame from the inside. Motorhome and trailer windows have waterproof and airtight rubber seals that prevent water ingress. It may require some elbow grease to remove the window.
Be cautious when thrusting the glass to prevent it from falling and shattering on the ground.
Step 3. Prepare the window area.
The window seal should also come off when removing the old RV window. If not, you might have to scrape the rubber seal from the perimeter. Moreover, remove any debris, dirt, or residue on the window hole.
Scrub the window hole with warm soapy water to remove dirt and residue. Rinse the surface thoroughly before drying it with a clean piece of cloth.
A clean surface ensures a better fit for your Hehr frameless RV windows or any other brand.
Step 4. Test the frameless window for fit.
I recommend verifying the fit of the frameless window into the hole before installing. Ask someone to assist you in placing the replacement window into the opening and check its fit.
Ensure the exterior window flange does not overlap while providing an exceptional seal to the RV’s sidewall.
Step 5. Prepare the frameless window.
Place the replacement window flat on a soft, padded surface to avoid leaving scuff marks or scratches. Apply a silicone rubber seal on the window flange to ensure a perfect seal on the opening. Remember to seal the trim flush and perimeter as well.
Step 6. Install the frameless window.
Have your assistant carefully lift the replacement window while you guide it into the opening. If the window is hefty, I recommend having two people slotting it into the hole while you support it from the inside.
Ensure the trim’s correct alignment before fastening the corner screws. I suggest starting with all four corner screws to secure the frameless window. You can tighten the rest afterward. Tell your assistant(s) never to let go of the frameless window until you fasten all screws.
Finish the installation by caulking the exterior perimeter. The seal should add another layer of protection against the elements.
I found a video by My RV Works, Inc. about replacing a broken frameless RV window. It is not the same topic we are discussing, but the steps are more or less similar.
Step 7. Assess the frameless window installation.
Installing flush mount RV windows is never complete without assessing installation quality and window function. That is why it is best to run a few tests before signing off on the project.
Try opening the frameless window as far as it can go, noting the ease of opening and any sound that may occur.
You can also spray water on the window corners to check for leaks, ensuring the perimeter is waterproof and airtight.
If there are leaks, you can add rubber sealant.
Step 8. Return the window treatments.
Finish the frameless RV window installation by putting back the different treatments. I suggest looking at these materials and replacing them with new ones, particularly if they detract from your newly installed window’s aesthetics.
