So when we build things like houses, schools, and hospitals we always make sure they are safe and strong. Materials You use. When we are building things there is one big thing we have to think about- what materials we are using. What is fire rated PU foam One of the very special material that plays a very important role to keep buildings safe from fire is the fire rated PU foam.
Fire rated PU foam is a special type of material which is used in buildings to keep them safe from fire. It is intended not to catch fire readily and can prevent the spread of flames if a fire does occur. This is crucially important as fires can pose a serious risk and can easily cause buildings to burn down if they are not insulated with fire rated PU foam.
How does fire rated PU foam work Fire rated PU foam acts in a way by which it separates the flames from the building. In case of fire, the PU foam will expand to form an insulating char which slows the passage of heat helping to prevent the fire from spreading. This can provide people with more time to leave the building, and it can also make it easier for firefighters to extinguish the fire.
Not only does fire rated PU foam protect buildings from fire, it also has other advantages. The problem it solved was that wool is an incredibly good insulator, so it helps to keep buildings warm in the winter and cool in the summer. This can save energy and money on heating and cooling bills. PU foam is also light and can be easily worked which is why it is popular in construction projects.
PU foam is a mass of small bubbles, filled with air. These bubbles themselves contribute to the lightweightness and flexibility of the foam but are also involved in its fire retardance. When the bubbles are heated or burned, the air in them expands and acts to retard the growth of a fire. That’s why PU foam can frequently be found in construction where fire-resistance is important.
