Thermo-Tec Cool It Supressor Mat, available on Amazon.

Noise and heat supressor mat. Did my doghouse about 4 years ago with it. Works really well. It is easy to cut, but be aware that once you place it, it's DOWN. When you remove your dog house you'll find a one piece moulded felt type insert. It removes in one piece.
Because of the contours of the dog house I cut the Cool It mat into easily placed pieces until entire doghouse was covered.
The original moulded insert will go back over the new mat.
One piece easily covered the doghouse with enough left over to put a good size piece under the drivers and passengers floor mat, directly on the metal floor.
Much cheaper than the Eastwood and Dynamat stuff and works just as well.
