Review on 🧱 Enhance Insulation with Foam Seal FNS500 Insulating Dispensing: A Comprehensive Review by Chris Santos

I had to foam quite a lot of windows so I needed a better option than disposable cans which would be too expensive. Styrofoam boxes are available here or at larger stores. The gun works as advertised, there is absolutely no reason to buy a more expensive gun commercially available and it's probably worse if it doesn't have a teflon coating. Because the valve is at the end of the keg, there is no more foam escaping when the trigger is released, and this is a huge advantage over disposable cans. Once you get the hang of it, you'll find that it's really quite easy to use and doesn't need any clutter. I bought a bundle of straws (designed for these guns) to attach to the end of the gun. They seemed attractive because they allowed entry into a smaller crevice than the barrel itself. But there are two problems with plastic straws: 1) When you release the trigger, the foam continues to come out of the straw as it expands inside the straw itself. This is more painful than it sounds as you really should NOT be getting foam ANYWHERE except for a tear. 2) It's almost impossible to keep the straw on the barrel. Sure if you squirt the foam in the air the straw will say it's ok but if you bend it into a crack or maybe the crack is a little smaller and the straw will rub against it and then break off. What a mess when the straw falls off. At several windows, I held the straw in one hand and the gun in the other, changing the straw for each new window. But in the end I gave up, the risk of damaging windows, walls and floors is too great. It's worth buying a can of detergent, you'll probably have enough of that for a lifetime. When changing cans, I manually squeeze some cleaner out of the can (just press the nozzle with my finger) to clean everything around the can attachment, also with my finger (in rubber gloves, of course). Foam is easy to remove every time. I let the foam dry on the barrel and then just tap it off, the teflon coating is the way to go!
