Why Choose Spray Foam Insulation?

Before getting into the costs of spray foam insulation, let’s remind ourselves of what’s most important: why you’re considering it in the first place. So here, we’re going to offer a quick reminder of the benefits:

  • It improves the thermal efficiency of the home, improving comfort and decreasing the cost of energy bills.
  • Seals the home by filling cracks, holes, and cavities in walls. Not only does this prevent heat loss and gain, but it can also stop pests from getting in.
  • Insulation also offers some soundproofing benefits, keeping the sounds of traffic and the neighborhood from disrupting the home at night.
  • Spray foams also aid in the control of moisture levels in the home because cool air is not as easily allowed into the home and thus cannot bring in the moisture that causes dampness and mould.
  • The resale value of your home could even get a boost. Energy efficiency has quickly become a key selling point for homebuyers, so insulation is an investment in the home that might pay off when it comes time to sell.

Quality Over Price

These companies entice customers by offering low-cost insulation alternatives. But what companies forget to mention is the quality of the insulation they are selling.

There has been continuous talk about the quality of insulation such as fibreglass, mineral wool, and cellulose being inefficient and ineffective. However, strangely enough, these warnings are overlooked due to the “bargain” you are getting.

Unfortunately, what these companies fail to mention prior to your purchase is that you will need to replace this insulation every few years.

I don’t know about you, but I’d rather spend money on good quality once than have to replace it every few years. This eventually accumulates, costing you more in the long term. This can become a burden.

Poorly insulated homes can also cause you to lose a drastic 50% of their heat, and that’s just through the roof. This can affect your energy consumption, causing your energy bills to rise through the roof.

Literally! This then means your home has a low EPC value, potentially causing your home to lose out on its potential market value.
