1. Faster Re-Entry Times
Because of the low pressure static mix that occurs during the application of Low pressure materials, atomization does not occur and VOC’s do not saturate the air; like they do during the application using high pressure systems. This allows occupants to re-enter the structure only one hour after the spray application has occurred. Also due to the low pressure static mix and no atomization, installers can wear PPE (personal protective equipment) that consists of organic vapor acid gas respirator cartridges. No fresh air pump is required like during the application of High pressure spray foam.
2. Simple & Minimal Equipment
The Spray Foam Hybrid's preheating and exact 1:1 ratio proportioning air pneumatic pump can easily be used as a portable system or as a mobile spray rig. The spray foam system requires less spray foam equipment to be used and it's small, compact size allows the unit to be put onto mobile cards, skids or into smaller vehicles such as a pick up truck or van.
Low pressure spray foam application will allow for a reduction of up to 80% in over spray during the application process compared to high pressure spray applications. The process temperature is also lower than high pressure formulations which makes applying low pressure spray formulation in colder climates ideal.4. Reduced Noise and Power
Because the heating of the chemicals takes place inside of the hoses, there is no need to have high capacity generators to drive spray machine so that noise and needed electrical power is eliminated. Many projects could take place in a very high density population area and there could be noise code ordinances that could limit the work that you do if you have a very noisy spray system.5. Reduction of 80% in Overspray
Low pressure spray foam application will allow for a reduction of up to 80% in over spray during the application process compared to high pressure spray applications. The process temperature is also lower than high pressure formulations which makes applying low pressure spray formulation in colder climates ideal.
1. The Spray Guns Are Plastic
If your low pressure spray system uses plastic spray guns, then you are constantly working to keep those in operation. Not only do you have to keep changing the nozzles, but during operation if you stop spraying for even a short period of time there is a very good chance that the chemical will solidify. " Darn, do we have another spray gun somewhere "
2. The Chemicals Are Expensive
If you are using low pressure spray foam chemicals that come out of a canister or tank, it's extremely difficult to compete in the commercial insulation market. Sure, you can use those chemicals if you have some small project that you want to spray foam with and you want the convenience, but you can not build a business around that chemistry. " I can not compete against the big rig guys "3. It's Hard To Spray In Cold Weather
When the ambient temperature drops below 60F degrees, any low pressure spray foam system is at risk of not being able to spray because the chemicals need to be heated. Sure, there are heating blankets and wraps, but now you have to manage that part of the system. "Does anyone know where those heating blankets are?"4. Where Can I Get My Chemicals?
No matter what low pressure spray foam systems that you are using, getting the chemicals can be a very difficult task. What do you mean? For many of us throughout the United States, because most low pressure canisters and tanks are pressurized then they are not items that we can not receive unless we order them and they have to be shipped to us."But I need those chemicals NOW! "5. It Takes Too Long to Spray
So many times when you are working, the opportunity to spray foam is in the moment. You need to be able to make that project work right now. Also, if you customers knew that you could fix something by spraying polyurethane foam, they would ask you to do more work. But your low pressure spray system is slow and takes too much time to set up. " Let's just use some fiberglass and stuff it into that knee wall "
