Mirror Insert Cabinet Door Bowing

2/26/15

Hello Everyone,

We produced a walk in closet which the client was very happy with, in the summer time, but we got a call today about two mirror insert doors bowing so we are going to replace these doors, Would some one have more insight on why these doors might of warped so much, one door warped enough that it pulled the hinge off the cabinet gable. I seam to think that since we cut out most of the Face of door to receive the mirror (7mm depth cut) on one side, that the door became unbalanced, that's why it pulled so much one way. We are now going to perform a different approach in the fabrication of the door, but if anyone has some additional ideas to fabricate this door please don't hesitate to let me know.

Door Material:
-19mm Particle Board Core.
-TFL Melamine Finish on both Faces.
-6mm Mirror Insert
-Silicone used to apply the Mirror to Door.

Thank You.

Samuel.

Is there a radiator right in front of the doors? Or in the closet? Or is the closet on an outside wall making it colder inside?

Are the doors stained on one side and painted on the other? Or are they unfinished?

Any one of these conditions might cause a door, that was stable in the summer, become warped in the winter.

Some thoughts to consider:

Wonder what the moisture content was at time of fabrication, especially during the summer. I would imagine better success now.

Use mirror mastic instead of silicone?

1/8" mirror instead of 1/4"?

Apply cabinet liner laminate to substrate before the mirror?

I had the same problem a bit over a year ago with a mirrored closet door. Mine was simply glued to a sheet of 3/4" mdf which was edge banded with pvc and a sheet of laminate glued to the back side. I struggled for a bit with how to re-make the door with a better balanced construction method which was difficult as I could not make the door any thicker. I ended up making a frame and panel door out of mahogany with 3-1/2"- 4" or so stiles and rails. Then I made the panels up torsion box style also out of mahogany. Glued it all up, sanded flat and installed a new mirror on one side with the same laminated back side. It's been over a year and just visited the home last week….still good.

It's quite a bit of work and I don't know if it will work in your situation but did OK in mine.

good luck,
JeffD

Your problem is unbalanced construction. Simple fix, do frame & panel with some clearance for the mirror. Back the mirror with a decorative finish.

I make a cope and stick door with glass rebate. The glass company installs a safety backed mirror. I do believe your issue is unbalanced construction. My solution would not match your cabinets or mine but it works. I tell then it is the only way I am willing to put a mirror on the door unless they are willing to spend more money for an aluminum framed door.

How did the silicone not eat the backing on mirror ? Many years ago one of my guys mounted a mirror with silicone , a couple of months later the backing dissolved and you could see the silicone through the glass. As for the warp was caused mostly due to unbalance , maybe mount the mirror on the door with a small molding ,it won't look as good but it may save the door

  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
