RV windows are exposed to a lot of wear and tear, from the elements to the constant vibration of the road. Over time, the sealant around the windows can deteriorate, leading to leaks and drafts. Fortunately, RV windows can be resealed, and the best sealant for the job is butyl sealant tape.
What is Butyl Sealant Tape?
Butyl sealant tape is a versatile and durable product that is perfect for sealing high-shock areas like RV windows. It is made from a synthetic rubber compound that is resistant to weathering, UV radiation, and temperature extremes. Butyl tape is also flexible and can withstand the constant movement and vibration of an RV without cracking or drying out.
Butyl tape comes in various widths and thicknesses, with the most common size being 3/4″ wide by 1/8″ thick. It is applied to the back of the window frame or around the bottom flange of a vent or skylight. When the window or other fixture is screwed into place, the butyl tape squeezes out, creating a tight seal that prevents water and air from entering the RV.
Why Use Butyl Tape for RV Windows?
There are several reasons why butyl tape is the best choice for sealing RV windows:
- Flexibility: Butyl tape can withstand the constant movement and vibration of an RV without cracking or drying out.
- Weatherproofing: Butyl tape is resistant to weathering, UV radiation, and temperature extremes, making it ideal for outdoor use.
- Ease of application: Butyl tape is easy to apply and can be trimmed off after the window or fixture is in place.
- Durability: Butyl tape creates a long-lasting seal that can withstand the rigors of RV travel.
How to Reseal RV Windows with Butyl Tape
Resealing RV windows with butyl tape is a straightforward process that can be done with a few basic tools:
- Remove the old sealant: Use a putty knife or other sharp tool to remove any old sealant or caulk from around the window frame.
- Clean the surface: Wipe down the window frame and surrounding area with a degreaser or solvent to remove any dirt, grease, or residue.
- Apply the butyl tape: Peel off the backing paper and apply the butyl tape to the back of the window frame or around the bottom flange of the vent or skylight.
- Install the window or fixture: Carefully place the window or fixture into the opening and secure it with screws.
- Trim the excess: Use a utility knife or scissors to trim off any excess butyl tape that squeezes out around the edges of the window or fixture.
It’s important to note that butyl tape should only be used for sealing the inside of the window frame. For the outside seal, a silicone sealant or other exterior-grade sealant should be used to create a weatherproof barrier.
Conclusion
Butyl sealant tape is the best choice for resealing RV windows due to its flexibility, weatherproofing, and durability. By following the steps outlined above, you can easily reseal your RV windows and prevent leaks and drafts. Remember to always use a high-quality butyl tape and follow the manufacturer’s instructions for best results.
