Polyisocyanurate insulation is magnetized and cut to fit, front to back. Installation is easy. The insulation comes in a kit specified by our architect. Pick up a piece and it snaps into place, held forever with a strong magnetic force that does not wear out. Any reasonable thickness (up to 7"). Order a finish on the lower portion to protect your investment in insulation.
The flexible, tongue and groove, cut along the radius of the arch give the insulation a solid continuous look
Pricing is about the same or a little less than spray insulation. If you want a smooth, neat finish call us for a specific building quote.
