If you need insulation at your home or building, you’ll be glad to hear that there are plenty of options available here at San Antonio Spray Foam Professionals for you to choose from.
Examples of the insulation options that you can choose from include the following:
Loose Fill Cellulose
Loose filled cellulose is one of the best insulation options it is effective at virtually all temperatures, and with an R-value of 3.2 to 3.8 per inch. The biggest disadvantage to it is that it is too heavy to use in the attic, and you will need to restrict it to ceilings that have a minimum of a half inch drywall or frame every sixteen inches.
Therefore, loose fill cellulose will be best used for ceilings in other rooms of the home, or in enclosed wall or new wall cavities.
Loose Fill Fiberglass
Unlike loose fill cellulose, loose fill fiberglass will be effective and light enough to use in attics, having an R-value of 2.2 to 2.7 per inch. However, loose filled fiberglass is also not as effective in exceptionally cold temperatures because as a product it is naturally fluffy (unless if it is topped by cellulose or a blanket insulation).
Polystyrene SIP comes in two different versions: Extruded (XPS) and Expanded (EPS). EPS is the less expensive option out of the two and has a lower R-value of 3.8 per inch, while XPS has a larger R value of 5 per inch.
That being said, both XPS and EPS are very easy to install, so long as it is cut specifically to fit around pipes and other types of wall penetrations. Polystyrene SIP as a whole is also best used for new walls, ceilings, and roofs (rather than remodeling existing ones).
Spray foam insulation is a good choice for forming an air barrier, which will help to prevent caulking and other weatherizing tasks. It costs more than many other insulation options, but it also has typically higher R values.
Open Cell Polyurethane Spray Foam
Open Cell Polyurethane Spray Foam has an R-value of 3.5 to 3.6 per inch. The biggest advantage to it is that it will stop literally all movement of air, but the biggest disadvantage is it can still allow water vapor to pass through, so you will also need to invest in an additional water barrier.
Closed Cell Polyurethane Spray Foam
Closed cell polyurethane spray foam has an even greater R-value than open cell polyurethane spray foam, at 6.0 to 6.5 per inch. The advantage to it is that in addition to stopping all movement of air, it will also stop all movement of moisture, so you will not need to worry about condensation. The only downside is that it is much more expensive, and it absolutely requires professional service in order to install, and cannot be done DIY.
