Case Study

Date: January 2012

Client: K.B.

Location: California

Product: Sing Door Panels

Challenge: Kevin wanted large carriage doors that fit his building without leaving drafty gaps.

Sing Solution: Only Sing door panels were strong enough and beautiful enough to serve his purposes. Our panels are precise and resistant to twist and warping, so they will remain a true fit for the door frame.


Customer Q&A:

What did you think of the panels when they arrived?

They looked just as I expected. High quality workmanship and to my exact specifications.

What was it like working with them to get the design you wanted?

Very easy to work with. The panels were totally flat and square.

What did you think of the panel’s weight in comparison to their size?

Weight came in as expected which is very light compared to a solid wood door.

Do you think that our garage door panels are equal in strength to

standard garage panels?

I think these panels are stronger than standard garage doors. Definitely stiffer.

If you were to do another project similar to this would you buy our

garage door core panels again?


Would you tell other people where you got your door cores from?


Please tell us in your own words about your experience with our panels.

I have nothing to complain about with regards to the entire experience. Customer service while ordering the doors was top notch. Price was great. Shipping/delivery was easy. Fabrication of my doors was straightforward.
