Have your heating bills been through the roof? Are you also struggling to keep your house cool during the summer? If so, you might have insufficient insulation. When your home isn’t insulated correctly, there’s a chance of drafts getting into the house during the winter and escaping during the summer.

Spray foam insulation kits

To prevent such an incident from occurring, you’d need to invest in spray foam to create a more energy-efficient home.

Spray foam insulation kits are a great choice because they can insulate all sorts of spaces from wall cavities to floors. They’ll also come with everything you need to insulate an area – whether open cell or closed cell. When you purchase a spray foam insulation kit, it’ll usually come with spray nozzles, a gun dispenser, and a hose. Some of them may also come with safety gear.

If you’re new to purchasing a spray foam insulation kit and not where to start, our comprehensive guide will help. We’ll talk about the benefits of getting a spray foam insulation kit and its pros and cons. Then, we’ll give some tips on what you should look for when buying a spray foam insulation kit and provide you with five excellent spray foam insulation kit options.

Benefits of a Spray Foam Insulation Kit 

Why should you be getting a spray foam insulation kit? To start, these kits help with reducing energy losses in a home by up to 50%. They also work better than standard insulation because it’s flexible and prevents air from leaking through. While it may be expensive to get everything set up in the beginning, you’ll be saving on energy expenses in the long run. Spray foam insulation helps seal up cracks and holes, so your utility systems won’t have to work so hard to compensate for lost air.

It also helps with deterring moisture. Water can easily seep through openings around pipes and vents – putting your home at risk for unwanted bacteria and rot. In other words, your home could be looking at some costly damage. By spray foaming your home, it’ll seal the tiniest crooks and crannies, so there are minimal chances of water seeping into your home.

If you’re not a fan of drafts, a spray foam insulation kit will help solve that. Spray foam insulation helps to create an airtight seal that’ll protect your home from the elements. It’ll prevent any temperature fluctuations in the building and will instead provide a consistently comfortable temperature. Unlike other insulations, spray foam also sticks to the surface, so you won’t have to worry about a hole that you may have missed.

Another great benefit of spray foam is that it helps minimize indoor allergens such as dust and pollen from entering your home. If you’ve got allergies, it’s especially helpful as there’s no way it’ll be able to come in through the walls. It’ll also prevent pests and rodents from coming into the home and is a non-toxic option that won’t release harmful contaminants into your space.

Spray foam insulation kits aren’t difficult to use. When you purchase a kit, you’ll get everything you need and just have to follow the instructions. Primarily you’ll be using a spray foam gun to spray the material on your desired area. After you’ve done the spraying, your insulation should be dried up and ready to go in about a day.

Spray foam insulation kits are also environmentally friendly since you’ll be consuming less energy in the long run. It’ll help reduce your carbon footprint, and you’ll be doing your part for the environment. It’s long-lasting since it’s only made of two materials and will never lose its shape. It won’t sag or shift over time even in various temperatures, and it’s also heat-resistant.

Another great quality of spray foam is that it’s incredibly dense and has strong adhesive qualities. With that, it’ll provide additional strength and structure to buildings while acting as a layer of protection against humidity and wind. Finally, spray foam also helps with reducing sound. If you’ve been woken up by noisy neighbors or road traffic, spray foam can help. The insulation absorbs sound waves and soundproofs your walls, so you’ll have a quieter home and more privacy.

Best Features to Look for

When purchasing a spray foam insulation kit, there are some things that you’d need to consider. The first thing to consider is the R-value. The higher the R of the spray foam, the better the insulating power. If the winters in your area are particularly cold or summers are warmer than usual, you’d want to opt for a higher R-value.

The next thing is to make sure that your spray foam is fire-resistant. Fires can happen, so you’ll want to make sure that your kit has a high fire rating. The next thing to think about is density. The higher the density of the spray foam, the better the insulation power, and the more soundproof and protected your home will be.

When purchasing your kit, you’d also want to consider if you’ll be installing the kit on your own or getting a professional to help. Some kits require professional assistance, while others can be installed on your own; you should read the recommendations before your purchase. If you’ve decided to do it on your own, make sure that the kit comes with all of the necessary hardware. Ideally, it should also come with safety equipment such as goggles and gloves.

Then, you’d also want to think about the color. Spray foam insulation does come in multiple colors from brown to white, so that’s something you’d need to consider for the interior of your home. The type of spray foam you purchase is also important as each one of them comes with a different density – depending on the purpose of your insulation, and the room you’d like to insulate.

As a brief overview, there are three types of insulation – high-density spray foam, medium-density spray foam, and low-density spray foam.

  • High-density spray foams are thick, moist-proof, fire-retardant, and great for all sorts of environments.
  • Medium-density spray foams, on the other hand, are relatively good as well and ideal for insulating and dampening noise.
  • Low-density spray foams are lightweight and generally don’t offer the same kind of insulation as the other types of foam. It’s mostly used for rooms that don’t rapidly lose warmth or aren’t connected to what’s happening outside.

The last thing to consider is open-cell versus closed-cell insulation. Open-cell spray foam is ideal for interiors and is cheaper than closed-cell foam. It also helps with dampening sound and can be installed at a low cost. Overall, however, they’re more suited for interior walls as they’re not great for sustaining the house.

On the other hand, closed-cell spray foam is a flood-resistant material that’ll offer reliable protection for your home; it can also work in very low temperatures and helps to add strength to the wall. Closed-cell spray foam is also moisture-resistant, has a high bond strength, and lasts long. They’re great for adding strength to your home’s overall construction and are usually used for exterior walls and roofs.
