Otto Bayer, the grandfather of spray foam, invented polyurethane in the 1930s. Spray foam eventually started taking off in the 1980s. DIY enthusiasts love using it today when they're insulating their properties.\r\n\r\nYou won't run into any problems, even if you're working in hard-to-reach areas. It's not just the first choice for DIYers. Professionals love spray foam insulation too, so let's look at why it's so popular with everyone.\r\n1. You'll Save Lots Of Money\r\nContractors will spend a bit of money on custom spray insulation machines solutions, but it's the only expensive thing about it. Once you've used the foam it's going to save you money over the years.\r\n\r\nIf you spend a few thousand per year on energy bills, it's going to come down when the foam plugs holes and cracks. You can also make extra money if you decide to sell up. Prospective buyers appreciate energy-efficient homes.\r\n2. It's Great With Moisture\r\nYour attic is susceptible to water damage when shingles blow off during a storm. Once rainwater hits traditional insulation it's a problem. Spray foam will always retain its properties even when it's soaking wet.\r\n\r\nWater won't reach your ceilings because the foam expands into every little area. It's worth replacing your shingles fast, but don't worry about water damage. Wet spray foam insulation is also superb because it doesn't attract mold.\r\n3. Avoiding Health Problems\r\nIt's hard to believe we used asbestos in insulation. Lung cancer is a steep price to pay for staying warm. You still need to watch out for fiberglass today because inhaling small particles is going to cause health problems.\r\n\r\nSpray foam is a non-toxic option that won't lead to issues a few decades from now. You won't end up with respiratory damage or itchy eyes. It's almost essential for people who suffer from asthma and allergies.\r\n4. It's Going To Last Years\r\nSome people don't live in cities where it's mild throughout the year. In some places, it's going to be extremely hot or cold. Spray foam has a high R-value meaning it's pretty heat resistant, so it's effective year-round.\r\n\r\nOnce it expands it's not going to sag over time, plus it will stay in the same position. All these qualities mean it lasts longer than other insulation. If you get lucky it might last for the lifetime of your home.\r\n5. Better For The Environment\r\n200 countries just agreed to cut CO2 emissions to net zero within 30 years. We're going to try keeping global warming under 1.5C too. You should be helping governments do everything to save the planet from an apocalyptic event.\r\n\r\nWill using spray foam insulation save us from Armageddon? I doubt it, but it's a step in the right direction. If the entire population does everything it can to protect the environment, it's going to make a difference.\r\n\r\nIt's The Only Good Choice\r\n\r\nIf you look around you'll find a few insulation options but spray foam insulation is the best. The benefits we've covered today are impressive considering it's made from two materials.
