Kingspan KS39 high rib panel: matching what is already on the building.
The Kingspan KS39 is an older high-rib wall and roof panel: five 1 1/2 in. ribs on a 38 7/8 in. module. If you are adding on to a building that has it, send us the panel details and we will work out the match.
KS39 was not listed on Kingspan's wall panel pages when we checked on November 2, 2026.

Matching a KS39 on an existing building.
KS39 is not a panel most new jobs call for. It comes up when a building already has it and the new work has to match.
Specification text names it the KS39 RW High Rib: a wall and roof panel with a high rib profile and a standing, nested lap seam at the joint.
We used this panel on a job years ago, so we know what you are looking at.

Questions buyers ask
What is the Kingspan KS39 panel?
An older Kingspan high-rib insulated panel for walls and roofs, with a standing, nested lap seam at the joint. Specification text calls it the KS39 RW High Rib.
What is the rib height and center line on a KS39?
Five ribs, 1 1/2 in. high, about 10 in. on center, on a 38 7/8 in. module. Check them against the panel on your building, because that is what the new work has to match.
How thick is a KS39 panel?
1 9/16, 2 3/4 or 4 in. Measure yours at an open edge if you can reach one.
Is the KS39 still made?
It was not listed on Kingspan's wall panel pages when we checked on November 2, 2026. That does not settle it, so send us the panel details and we will find out what can be done.
What is Kingspan's current ribbed panel?
KingRib is the ribbed wall panel on Kingspan's site now. Whether it lines up with an existing KS39 comes down to the measurements.
Can a new panel match an old KS39 wall?
That depends on the rib height, the rib center line and the panel width. Send them and we will tell you what lines up and what does not.
