Foamboard insulation is often recognized as one of the least cost-efficient insulation materials. It has a low R-value and can be quite expensive to install. However, it is important to consider more than just cost when selecting insulation for your home. Foamboard insulation can also have negative health effects and may not be the best choice for those with respiratory issues. Here are some additional reasons why foamboard insulation may not be the best option for your home:
Foamboard insulation has a low R-value, which means it may not be as effective at insulating your home as other materials like fiberglass or cellulose insulation.
Foamboard insulation can be more challenging to install, which can lead to additional labor costs.
Foamboard insulation can also release harmful chemicals into the air if it is not installed properly or comes into contact with fire.
Foamboard insulation can trap moisture, which can lead to mold growth and other moisture-related issues.
While foamboard insulation may seem like an attractive option due to its ease of use and relatively low cost, it is important to consider all factors when selecting insulation for your home. Other materials like fiberglass or cellulose insulation may be a better investment in the long run, as they offer higher R-values and are less likely to cause health issues.
