With Spray Foam Insulation it's important to hire a professional

January 27, 2017

Spray foam insulation has earned a reputation as the best product of its kind. It's simply because it delivers results. When professionally installed, SFI is an effective sealant, an excellent insulator, and a practical soundproof barrier. Overall, there isn't a comparable product that can challenge the efficacy of spray foam - which is why more and more professionals are suggesting the install. On the downside, home improvement centres are promoting more of a DIY approach with spray foam. They offer various products, assorted installation tools, even ready-to-go kits. But bottom line, spray foam insulation demands the experience and expertise of a professional. The chemical compounds require careful handling, and the installation itself requires skill and proficiency. Like most specialized work, insulating with spray foam is about doing the job correctly in the first place. Having to do a re-work, because of a poor installation, can pose problems - it's costly, it's time consuming, and it's stressful. Worst-case scenario, a spray foam installation that is managed poorly can often compromise the health and well being of building occupants and/or residents. Professionals know how to properly manage a spray foam project. They know how to prepare the jobsite prior to the installation. They understand the nuances of the chemical compounds. And they are familiar with the unique complexities of an installation. Most importantly, a professional approach ensures that everyone is protected and safeguarded in and around the working space. Spray foam insulation should not be viewed as a weekend DIY home project. For the uninitiated, there is just too much risk. There could be issues with the installation itself. There may be health concerns. And there may even potential damage to the home. Worse still, once the spray foam has been applied, any problem areas will have to be remedied by a professional and with added cost. The point is, this is work for professionals - for those who are trained to handle the chemicals and qualified to operate the equipment. In fact, the best contractors are licensed and certified. And once finished, both product and installation can be guaranteed to perform. The critical thing for a homeowner is good short-term results and long-lasting performance, all without any problems. Because the spray foam product is so unique, a professional installer is crucial to success. The chemical compounds need expert preparation. The foam application requires thorough layering and meticulous coverage. And because the foam cures and hardens quite quickly, precision is key to creating an effective insulating envelope that will efficiently seal and insulate a given space. To be sure about professional installation, industry associations encourage consumers to choose contractors carefully and assess the warrantees and guarantees that might be provided. Needless to say, an informed consumer makes better decisions, and one of the better decisions is to work with a professional. This will prevent any potential pitfalls, as well as problems down the line. It's really quite simple with spray foam insulation - it's far better to do it right the first time around.
