Another major quality of composite doors is their superior insulating qualities. While the GRP outer skin offers style and durability, the inside of the door consists of polyurethane foam. This offers a high degree of both sound and heat insulation. This insulation means your composite door will keep out annoying street noise and make your home quiet.
Plus, although \"fire doors\" can be purchased, businesses still receive excellent protection against the spread of fire with steel security doors. Steel doors also provide increased energy efficiency, since they insulate the cold air from outside up to 4 times better than wooden doors.
If the workplace consists of several offices/rooms in a commercial building open to the public a business is at even greater risk and security alarms often do not bring authorities until 10 or 15 minutes have passed. The workplace entered, and valuables taken, this is plenty of time for a wooden door or doorframe to be broken. There is a reason that most safes and safe deposit boxes aren't made of wood!
