Spray foam insulation outperforms all other types of insulation on a consistent basis. Unfortunately, while polyurethane spray foam is effective at both insulating and sealing, it contains ingredients that can have negative health effects if not handled properly. Isocyanates, for example, can cause skin and eye irritation, asthma, lung damage, and other respiratory problems. There are several steps you should take to keep everyone safe, whether you are the applicator, a helper, or an occupant of the building being sprayed.
Spray Foam Insulation Installation
To begin, read the product information for instructions on how to apply the product, as well as safety practices, precautions, and hazards. You can avoid exposure to potentially harmful ingredients if you take all necessary precautions. In addition, based on the manufacturer’s recommendation, determine the safe re-entry time for unprotected individuals.
If you have any breathing problems or health concerns while applying the foam, seek immediate medical attention. Only properly protected individuals should enter the work area once the foam has been applied. Aside from that, fresh air is essential. Make sure you have adequate ventilation. It is critical to avoid chemical exposure while the spray foam insulation cures after it has been applied. To accomplish this, keep the work area closed to everyone for the predetermined amount of time.
Following the application of the Spray Foam Insulation
Read all instructions carefully to determine the exact time required for curing. For two-component, high-pressure spray foam insulation, some manufacturers recommend 24 hours. This is commonly referred to as “professional” spray foam. The curing time for one-component foam, which comes in 12- or 24-ounce cans, can range from 8 to 24 hours. In general, 24 hours should be sufficient for safe re-entry without the use of protective equipment. Rather than rushing this part of the process, it’s best to be on the safe side and wait longer than specified. If this estimate is not found on the product label, contact the manufacturer or supplier for the re-entry time.
Spray foam insulation becomes chemically inactive when properly applied and allowed to cure. However, there are a number of factors that can influence curing rates. Temperature, humidity, improper workplace practices (such as not sealing air vents or shutting down the HVAC system), improper foam mixing, and other poor application techniques can all affect curing times.
Is Spray Foam Insulation a Do-It-Yourself Project?
Spray foam insulation is a simple do-it-yourself project. In this case, homeowners can apply the insulation with spray foam cans or kits. These kits always come with instructions on how to use them. Larger projects, on the other hand, should be handled by professional contractors. There are simply too many factors that could pose greater potential health hazards with a large project. For application, they typically necessitate the use of protective equipment as well as specialized skills.
