Building laminated veneered doors

[Dan Chouinard]

John, thick skins are fine over a solid wood stave core. If using LVL or Timberstrand type Cora then you need to use thin veneer. Myself I would not use 1/8” on an exterior door. Plenty of manufacturers do though.

Joe, what is your definition of "thick" skin?

[Joe Calhoon]

Thanks Joe. I thought the Germans were/are putting 7 mm over a composite core?

Always solid Stave core with the 7mm. Aluminum strips optional for stability.

Hi Dan, I would say anything thicker than 3mm. After 3mm skins start acting like solid wood.

Thanks for the clarification, Joe.

Aluminum has very high thermal expansion compared to wood. How those strips provide stability is a mystery to me.
