Tested Open Cell

Installation is similar to that of closed cells, but the effects are different. Open cell foam sprays expand once applied, allowing them to be installed in hard to reach, out of the way nooks and crannies. This includes wall and ceiling cavities that can be difficult to seal with closed cell foams. The expansion feature will hermetically seal the area and provide proper insulation. However, the R-value of open cell polyurethane spray foam is lower, in the 3.6 to 3.8 per inch range. This means its heat resistance level is lower, which can cause insulation failures in extreme temperatures. Because open cell foam is still very dense, it provides good insulation. Open cell spray foam does not have water resistance, though, and its lower strength provides less support to walls. It is also more permeable to vapor and air, and lower noise frequency ranges.

Another positive attribute of open cell polyurethane foam is its cost. Because of its disadvantages compared to closed cell foam spray, it is more affordable. This can be a great boon when an application does not require airtight seals and hermetic moisture prevention. Caution needs to be taken, though, that the less expensive alternative does not lead to more expensive repairs in the future. Establishing the needs of a given application are important before choosing which foam spray to use.

Why Is The Hybrid Unique?

The Spray Foam Hybrid processes high pressure formulations with a low pressure system. This exciting new spray technology has many new advantages that could potentially reshape the way we apply SPF in the future. One of the largest benefits to the Spray Foam Hybrid is that due to the low-pressure processing, we are able to apply the SPF through plastic dispensers, which provides many benefits to the business owner and the production installers. At a price of less than $100, this reusable dispenser provides spray foam business owners with an economical solution for processing SPF chemistry. Most spray foam contractors would agree that their biggest set backs are finding skilled personnel. Training for new and current spray foam installers on equipment is a very lengthy and can be a difficult process. High pressure machinery requires knowledge of all equipment. The normal high pressure spray gun can have as many as 50 parts. When the spray foam gun fails, the installer much be able to determine the case as well as what parts failed which can cause delayed times in production, which means loss in profit. With the Spray Foam Hybrid, installers will enjoy the east of us of the gun, including weight, flexibility and overall performance. Extensive mechanical experience for repairs is not required as the gun is considered a wear part and is simply replaced when needed. Downtime is eliminated as the change out of a new gun is as little as five minutes or less. The Spray Foam Hybrid saves time, lowers material and transportation costs and eliminates drum disposals.
