I just glued my door cards with lapage construction adhesive the one that is 8 times stronger than the regular glue.
Glue door interior panel to foam.
The stuff is thick requires a lot of force to dispense it with a caulk gun.
A water repellent pp film or foam panel is used inside every single auto door.
2 take the interior side of the door panel and lay it face down on your foam.
The continuous beads of adhesive are in depth and applied in a zigzag pattern.
Cut a sheet of rigid foam insulation to fit each section.
The pp film or foam panel can prevent water from entering into an auto interior during raining or car washing.
Do any necessary trimming of the foam board before applying adhesive.
I used clamps to keep the pieces in place and gave it 24 hours to cure.
The adhesive is applied four inches in from each vertical edge and to the center.
3 use a marker and trace your door panel onto the foam.
5 at this point spray the panel side of the foam with adhesive.
Foam seal tape 3 rolls 1 2 inch wide x 1 8 inch thick high density foam strip self adhesive neoprene rubber door weather stripping insulation foam window seal total 50 feet long 16 5ft x 3 rolls.
Hold the foam board insulation in place for a few minutes to allow the adhesive to bond to the wall.
1 place your foam on the table.
While you can attach foam insulation panels using nails gluing them is less labor intensive.
4 remove the door panel from the foam and cut out your newly traced outline.
Use 1 1 2 inch thick insulation for doors with metal framing and 2 inch thick material for doors without it.
Foam insulation is an important part of maintaining energy efficiency inside and outside the home.
