Wall insulation is one of the most important investments you can make in your home. By adding this layer, you're helping to keep your home more comfortable, quieter and more energy efficient. The benefits of retrofit wall insulation extend beyond just saving money on your utility bills; it also keeps your home dry, mold-free and quieter (which may help you sleep better at night). 

Wall insulation also helps to reduce condensation problems that can cause moisture damage over time. With all these benefits for such a low cost-per-square foot investment (compared to roofing), there's no reason not to consider adding wall insulation or upgrading existing walls with spray foam insulation if you own an older house still lacking this crucial component!

Improves energy efficiency

The best reason to invest in retrofit wall insulation is because it can save you money. If you're already paying for heating and cooling, then reducing those costs will have a direct impact on the bottom line of your energy bill. In addition, less time spent running fans or air conditioners means that you're using less power overall which reduces carbon emissions into the atmosphere.

It might seem obvious that insulating your walls will help keep them cooler during summer months and warmer during winter ones--but did you know that there are many other benefits as well? For example:

Lessens noise from outside

Reducing noise from outside is one of the biggest benefits of wall insulation. This can be achieved by reducing or eliminating unwanted sounds, such as traffic noise and aircraft. Wall insulation also helps to block out sound from neighbours and even train tracks.

It's easy to imagine that an investment in retrofit wall insulation would be worth it if it only reduced your energy bills by a few hundred dollars per year--but what if there were other benefits? What if installing this product could help reduce the risk of fire hazards caused by excessive heat buildup inside your home? And what if doing so meant you could finally enjoy some peace and quiet at night when everyone else around you has gone to bed?

Helps to keep your home dry and mold-free

Mold is a fungus that grows on damp surfaces. It can cause allergic reactions and respiratory infections for people who are sensitive to it, as well as structural damage to your home. Mold can also be a health hazard for infants, the elderly and people with chronic lung conditions.

Mold thrives in warm, humid conditions--the kind that often develop during the summer months when you're running your air conditioner full-blast. If you're not careful about keeping your home dry during this time of year (for example by regularly cleaning up spills), then mold may begin to grow inside your walls or ceiling insulation--and once it gets started there's no stopping it!

The good news is that retrofitting insulation with rigid foam boards will help keep moisture levels low enough so that no mold forms at all

Conclusion

Retrofitting your home with retrofit wall insulation is a great way to make it more energy efficient. The ROI on this investment can be as short as one year, depending on how much you're spending on your utility bills. If you're looking for ways to save money and reduce your carbon footprint, it's time to consider adding wall insulation!
