Our 'mansard' style pool cage is about 16 years old and the Phifer 18x14 screen has held up well for the most part. Can't complain after getting 16 years considering the FL sun and annual pressure washes. Now we have about 14 panels that should be replaced due to silvering, small tears and fraying at edges - since more will likely follow soon we are considering rescreening the whole cage.

Bugs have not been a huge issue with the 18X14 screen. We do get some (well the spiders and lizards get them mostly) but with conservation in the back, the screen door in use, the drain channel open on both ends (would love to screen that in) and some potted plants inside the cage, there will always be bug instrusions. Thankfully the noseeums are not a real issue where we live.

We love our view and the 18X14 screen helps that view, but there are some downsides. We have pine trees in the conservation behind our home and those needles always find their way through the roof screen. Also, in the rainy season, we will get clusters of bugs (ants or thrips - not sure) clinging for life on the surface (Dawn mixture is not their friend). Sharing those concerns with a few screen installers brought up the option of the Phifer 20X20 noseeum screen on the roof. Perhaps getting 20X20 screen on the 1200 sqft. roof might help with those issues - not eliminate them of course.

However, I understand there are downsides to 20X20 screen. Airflow is somewhat reduced - the walls would still be 18X14 so that should help with airflow. Apparently it is common to mix screen sizes or thickness based on needs. Another issue is the shading effect - not sure how much solar radiation is reduced but I understand that 20X20 screen will drop the pool temperature by a few degrees compared to 18X14. That might shorten the swimming season or increase the demand on the heater. I am also concerned that if it takes longer for the lania to dry out after a rain then it will lead to increased mildew growth. I realize that additional shading can be a benefit too - there are always tradeoffs.

Has anyone made the switch from 18X14 to 20X20? What was your before and after comparison? Any pros or cons that I missed?

Thought of another question - while they are rescreening, is there any maintenance I should have done while the screens are off? I thought of cleaning out the gutters but wondering if I should get the gutters resealed too. Anything else?

Same situation here in The Villages (10 yrs old)...some screens fine(aluminum charcoal color) others compromised..some insects but minimal..ss brillo at drain ends keeps most geckos out and our 2 kitten cats handle the rest. As far as maintenance, we have wiped down the cage framework(green mildew) and touched up any fasteners that have rust. We are thinking of using Tuffscreen for the lower panels as they would be more cat claw proof. Our pool screen enclosure is white. I wasn't aware there were gutters for these. I see you have a V green 1.65. Mine just arrived and will be installing soon.
Very interested in what your choice is for screening...gets quite hot here in Fla...thank god for deck cool.

Yes, agree on the cool deck - makes it possible to walk on from pool to covered area in August. I hadn't though of the brillo/steel wool for the drain ends - seems like a simple fix to keep more critters out. And easy to replace if it gets all gunked up.

The aluminum gets a wash each year which helps keep the gunk off, but with the bronze color dirt doesn't show a bad anyway. Hadn't thought about touching the rusted fasteners - what did you use for that?

Regarding screening, we are probably going with the 20x20 noseeum screen on the roof panels. It is an upcharge but we are hoping the pros outweigh the cons. Here are some photos of the annoying pine needles that are getting through the 18X14.

If the cats are clawing the lower panels then it may be worth the super screen - supposedly it has a longer warranty but not sure if details of the warranty allow for pet damage.

Our original pool and enclosure build (T D Pool Wildwood Fla) has exact match for white and bronze that they used. Walmart has many colors 50 cent touch up bottles in there arts and craft sections that might get you buy.
BTW what is meant by 18X14 to 20X20 type?

Thanks for the tip on the paint.

In regards to screen types, here is a link to Phifer's product page Pool and Patio Products Archives - Phifer
My understanding is that 18x14 and 20x20 refer to count the threads per square inch.
