|* Thread Denier is the thread weight. Our heavy mosquito netting is lock stitched with an effective denier of 450 for our most popular heavy mosquito mesh.
As a point of comparison, the netting you see on aluminum gazebos at home improvement stores is about 90 denier.
||No-see-um / Mosquito|
Our no-see-um netting has nothing to do with visibility. It has tinier holes (800 holes per square inch) to keep out a particular biting insect called a no-see-um.
A No see um, also known as a midge fly, sand fly, or micro-gnat is a tiny relative of the mosquito. They are about the size of a ridge and a half of a finger print ridge. If you have never heard of no-seeums you probably don't have them in your area. No-see-ums live generally within 500 yards of lakes, rivers, ocean, or marshy wetlands.
Our no-see-um netting mesh is gorgeous, but the drawback is that it is denser and catches the wind more, so it needs to be better secured. Our system is frame less and is designed to operate with wind speeds less than 22 mph. Above 15.7 mph, biting insects are unable to fly.
Our tracking attachment option enables you to draw the curtains open under heavy winds to enjoy the fresh air without the worry of bugs. If no-see-ums are not an issue for you, we recommend the heavy mosquito mesh.
As you probably already know, light is a wave and has qualities similar to water waves. Imagine tossing a pebble into the still water of a pond. The impact of the pebble would create concentric waves that would radiate outward. The waves themselves consist of peaks and troughs.
If you were to place a slotted gate in the path of the radiating waves, smaller wavelets would emerge on the other side of each of the slit holes. As these wavelets emerge from the slit holes, they too would consist of peaks and troughs.
As these wavelets radiate into each other, the wavelet peaks will cancel the troughs of adjacent wavelets. If it is a perfect collision of equal magnitude, the waves would disappear completely. However, it is more often an imperfect collision and the intensity of the wave is only reduced. The result is what is called a "wave interference pattern."
If you were to throw a handful of pebbles into the same pond, you would have a momentary disturbance; but, the peaks and troughs will quickly cancel each other and the disturbance will settle quickly.
Our no-see-um mesh has 800 holes per square inch. And two factors reduce the intensity of light. The first is that the threads themselves physically block some of the light. In addition, the interference pattern reduces the intensity of the light that passes through. In fact we sell to the film industry who makes giant outdoor "butterfly screen" light filters for outdoor scenes and to the military for urban camouflage.
