# Floor Boards

A household's floor loses 10% of its heat. Insulation is the best option for improving the thermal envelope in a home by reducing the U Value of its floor, wall, or roof, in accordance with current building codes. Rockwool Insulation is a better choice if you are looking for fire resistance insulation. Floor insulation boards are designed to keep your home warm.
