Mud dauber screens

When you install ANY type Insect screen over the outside refer vent, you cut the air flow volume by about 50%. Big deal? Yes, when it gets over 70 degrees outside.

Wouldn't the amount of air flow be dependent on the size of openings in the screen? I've done it for many years and have noticed no degradation in the cooling ability of my fridge. Having 2 cooling fans at the top of the vent may help offset any reduction in airflow ability.

I agree With dougrainer. I am from Texas and you need lots of ventilation for your refrigerator especially if it is a fridge in a slideout. Definitly use screens on heater and water heater.

Not if the screen is designed correctly.

My furnace screens are convex. With a convex shape the total screen opening equals the opening without a screens installed.

For the frig I've always hot glued fiberglass screening from the hardware store to the inside of the side and top vents.

I do the same for the openings under the gas bottles, and door louvers, or any opening that need to be protected.

Now's the time since everything is clean or will adhere without too much cleaning.

I've had the same screen hot glued on my 5thW for 13 years and about 50K miles, hasn't fallen off yet.

I've never bothered with the water heater. I open it gently to prevent surprises and use a vent brush on the burner tub if necessary.

That never took much effort and I'm not sure how standard window screening would hold up to the water heater exhaust.

I put Camco stainless furnace screens on both my current campers. There a bit pricey for what you get but they look nice, work well, and are easy to install.
I don't believe there much difference in any of the brands.

I cut galvanized hardware cloth to fit behind the removable vent cover for the refrigerator. I bought the WH and furnace stainless steel vent covers mesh from Camping World. I have had no problems with any of them after years of use.
I also put hardware cloth under the LP tank storage bays (2) to keep out the wasps and nests. I screened the back open area of the fifth wheel hitch where birds like to nest.

Dave,

You will need to tell us what brand appliances you have, as the screens are brand-specific.

And, is this for use 100% of the time or just while in storage? The "while in storage" is a lot cheaper (cheap nylon screening that you close in the appliance door/access panel).
