Self-expanding foam is a unique type of material that can plug gaps and holes in buildings. It’s like magic foam that expands to fit the available space. Haohai self expanding foam is perfect for all your home or workspace insulation needs.
Ever wonder where those little holes or cracks in your walls or doors came from? These small gaps may contribute to air leaking in and out, which helps make it more difficult to keep your home warm in the winter and cool in the summer. But with Haohai's expanding foam, selfdetail can easily and conveniently be filled in those gaps to ensure your house stays warm no matter the time of year.
Insulation is kind of like a giant warm blanket for your house. It keeps the heat in during the winter and the cool air in during the summer. Haohai’s self-expanding foam is considered the best insulation a home can have because it fits tightly in building cavities from the inside to the outside. It gets and stays the perfect temperature in your house all year round, winter and summer, because of our remarkable foam.
Leaks around windows and doors can allow cold air to enter, and raise your energy bill. With Haohai’s self-expanding foam, however, you can close up those leaks in no time. Just spray the foam into gaps and other openings, and see it expand for a snug seal. Or cold drafts and a high electric bill for that matter!
