We use a square sticking profile that isn’t quite 90°. This simple design enhancement offers substantial performance advantages. Though not obvious to the casual eye, you’ll be amazed at how this profile eases finishing and cleaning, yet achieves a classic look.
The MDF hinge edge is inserted at 90°. This provides a sturdy mounting plane for hardware, an edge that won’t split like wood. Talk is cheap, so in an independent slam test, our doors performed over 519,000 slams (which exceeds the commercial Heavy Duty standard) before we stopped the test.
For IHS Door Company that wasn't quite enough, we took it further by performing several more of our own tests. One test simulated on the job removal of hinge screws, by hanging the test door, removing the hinge screws 2 times, and reinstalling them before starting the slam test. After 100,000 slams we removed and reinstalled the screws, and successfully completed an additional 25,000 slams before electing to stop.
STILEChoice® doors create new opportunities for architects, designers, and interior decorators. An excellent example of this is our 7'6" door. A door in this height isn't available from most manufacturers. Those who do offer it generally add a significant upcharge and long lead times. The 7'6" STILEChoice® door costs only slightly more than the standard 6'8" door. Architects, designers, and interior decorators agree that a 7'6" door is the perfect compliment to a 9' ceiling -- an increasingly popular height.
Made 100% in the USA, not imported. So no waiting, no size or design limitations, and superior quality control. STILEChoice® Doors are MDF stile and rail construction. STILEChoice® MDF is a 95% (or more) recycled material that delivers superior design advantages and finishing properties. Its a less complicated, more versatile product, easily adapted to any design.
Medium Density Fiberboard (MDF) does not contain knots or rings, making it more uniform than natural woods for manufacturing and finishing.
To many, it might be "just a door", however, at IHS Door Company we hold unparalleled quality as standard. But don't take our word for it, just ask NRRI an independent testing lab where we recently submitted a 3'0" by 8'O" door to their slam testing. The test was stopped at 519,569 slams, not because of failure, but the test required only 500,000 slams. See below for excerpts from the report prepared by NRRI and download the pdf version to read and see all the details.
To evaluate the performance of a 3-0, 8-0 door constructed by IHS Door Company during the NWDA TM-7 Cycle Slam Test.
One 3 ft- 0 in. wide, 8 ft- 0 in. tall, 1.75 in. thick door was constructed by IHS Door Company from medium density fiberboard. This door was painted white by IHS staff prior to delivery to the Natural Resources Research Institute (NRRI). At the completion of testing, the door was returned to IHS Door Company.
Inspection of the door showed the following:
Improper handling will void the warranty for warp.
Doors should not be delivered to the job site until all other trades are complete and concrete floors, plaster and drywall are completely dry.
Doors should be stored flat in a dry, well ventilated area. The doors should not be placed directly on the floor, but placed on at least three equally spaced supports (2x4 or similar). DO NOT LEAN DOORS up against the wall (doing so will void any warranty for warp).
To properly finish the door use a high quality paint and apply it in strict accordance with the manufacturers specifications.
Be sure to patch any minor dents or scratches that have occurred during handling. Do any required final sanding and be sure to wipe the door clean before applying any paint.
Doors are to be finished on both sides and all four edges. Do not leave one side unfinished for a prolonged period of time; when finishing the doors both sides should be finished at the same time. Prolonged time between finishing the 2 faces of the door can lead to warping and void warranty for warp.
Use the same size screws that would be appropriate for the size and weight of the door.
Pilot holes are required and should be between 85% to 90% of the root-diameter of the selected screw and drilled to a depth greater than the screws driven length. Screws should not be overtightened — set the clutch on your drill to minimum.
Use 3 hinges on 6’8" and 7'0" doors, and 4 hinges on 7’6" and 8'0".
