Wood Decks

Wood Decks form an ideal base to cover over which to apply cedar shingles or shakes, since they can be attached in the conventional manner. Where a layer of insulation, normally one of the rigid types is to be included, the problem of how to fasten shingles or shakes is created. The use of abnormally long nails driven through the shingles, the insulation, and into the deck below is generally unsatisfactory, and horizontal strapping will be required to overcome the fastening difficulties (Figure 23, Page 18.

When strapping is used, fewer nails penetrate through the insulation to the deck, and greater thermal efficiency is achieved by reducing the number of conductors.
