Protect Your Home With Fire Doors From Nick’s Building Supply

There is no need to sacrifice beauty and the enjoyment of natural wood in order to provide protection for your home. At Nick’s Building Supply, we have a full line of fire doors which are 20 minute rated to provide you and your family with the protection you need.

Our fire doors including mahogany fire doors and alder fire doors, all offering a different look. These come as prehung doors, and with their different styles and designs it is possible to find a beautiful, natural and lustrous wood door offering the protective elements you require.

The Look

Alder fire doors include knotty alder which ensure no two doors are identical. These doors feature clavos, the traditional black cast nail heads to add to the look and design of the door. With the knots found in the wood creating an interesting pattern, these are a one of a kind safety doors.

Traditional mahogany fire doors also have a unique look. From Shaker styles to panels, these sleek doors will add to the look of any room or home without looking like the very heavy and flat looking fire doors offered by other companies.

The Options

At Nick’s Building Supply, we provide the option to stain the door at our factory to suit any color you wish. By going online, you can see our stain samples and then determine which is the best match for your home colors and design.

All of our fire doors are designed with a fire-retardant core and intumescent seals around the exterior. This inhibits the fire and provides your family additional protection to get to safety.

Our mahogany fire doors and alder fire doors are tested extensively and meet most local building codes for fire safety. Our doors are approved as fire doors in the United States as well as Canada, and can be used in residential or commercial applications.

To learn more about our prehung doors, give us a call today at 219-663-2279. We would be happy to answer your questions and talk to you about any special considerations you may need.
