Guide to RV Window Weatherstripping - Stationary Glass

Windows provide more than a spectacular view of the outdoors.  Every detail of the window provides the same safety, comfort and quality you look for in a home.  Windows on an RV can provide light, ventilation and emergency egress - but most importantly they give the RV enthusiast a view of the beauty that surrounds them.  When window seals fail or go bad, the results can be costly and likely ruin the RV experience.  RVs are a great option for comfortable camping, weekend getaways and in some cases – long term living.

As with most things, however, items wear out and need replacing including your window weatherstripping.  Window weatherstripping is often an overlooked feature on the window design, but it is one of the most important. If you have drafty windows – more than likely new weatherstripping is needed. Replacing your stationary window weatherstripping is an affordable option and something you can do yourself!

Window weatherstripping is wedged between the glass and the retaining metal frame to act as glazing and seal out the elements.  Because of this, stationary glass window seals for RVs are dependent on the windows themselves. 

What are Stationary Glass Windows?

Stationary RV glass windows are the simplest in design, the easiest to manufacture and the lowest in cost. 

Surprisingly, there are multiple types of stationary glass windows and knowing which one you have on your RV will help you determine the correct replacement weatherstripping.

Picture Windows
This is the main type of stationary window that you will find on an RV.

Pop Out Windows
Pop out windows have a hidden hinge on the top and open from the bottom. These windows offer great ventilation and if it’s raining, the rain is deflected away while this window is open – meaning no moisture creeping inside the RV! Who doesn’t love fresh air during a rain shower?

Emergency Egress Windows
Egress windows are designed with a quick release frame that can be removed in an emergency.

Combination Windows
As the name implies, they consist of a window that features both stationary and sliding glass. These windows can be found on sides and doors.

Identifying Problems with Seals
There are 3 key factors to consider when inspecting your window weatherstripping.

The first is exposure. What kind of environment are you traveling to in your RV? Annual beach trips with the family are always fun, but the salt in the air can be damaging. Salt is aggressive for the body of the RV as well as the weatherstripping. If you are RV camping at the beach, make sure to stop and wash everything well when you leave the coast. This will help slow down the effects of salt air damage.

Secondly, how old is your RV? If you bought the RV brand new, you won’t have to worry for several more years about replacing weatherstripping unless something extraordinary occurs. If you bought the RV used, you probably do not know the last time the weatherstripping has been replaced. Check the weatherstripping thoroughly for damage or looseness.

Lastly, consider the quality of the weatherstripping you are using. Going back to exposure for a moment, you RV spends a considerable time outside in the elements. Your weatherstripping needs to be the first defense against water and wind. Having a strong, high quality (and preferably UV resistant) window weatherstripping is key for a long lasting life.

 If you want to know how well your window weatherstripping is holding up - take a look. Do you see any dirt collecting?  Where there is dirt, there is moisture! Moisture is the underestimated enemy of RV weatherstripping and the overall health of your RV. Moisture can lead to mold which not only leads to damage of the RV, but can also be detrimental to your health. 

Important Steps to Replace Seals
Measuring is the first step in replacing old or worn out weatherstripping. Using a measuring tape make a note of the circumference of the window. Weatherstripping is sold by the foot, so we always recommend purchasing a little extra. What is it Dad used to say? Better to have it and not need it than need it and not have it.

Once you know how much weatherstripping you will need for your stationary window, it is time to find the perfect fit. Take a look at the end profile of your old weatherstripping. You will be able to use this profile and match it to the profiles we have available.
