Abstract
Abstract A rigid surface is insulated by a plurality of studs projecting perpendicularly therefrom; a first layer of insulation boards placed against the surface; a plurality of wooden strakes positioned over the abutting insulation boards of the first layer and secured to the studs; a second layer of insulation boards attached to the first layer; and a third layer of insulation boards held in contact with the second layer by means of fasteners secured to the wooden strakes in the first layer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
154 words
An insulated surface comprising: a rigid surface having a plurality of studs projecting perpendicularly therefrom in spaced-apart rows; a first layer of abutting insulation boards placed against the surface, said insulation boards being spaced so that the studs are in abutting joints of the insulation boards; wooden strakes positioned over the joints of abutting insulation boards of the first layer, said wooden strakes being secured to the studs; a second layer of abutting insulation boards having abutting joints substantially parallel to, but offset from, the joints in the first layer of insulation and held in face-to-face contact with the first layer by fastener means secured to the wooded strakes; and a third layer of abutting insulation boards having abutting joints substantially parallel to, and in line with, the joints in the first layer and held in face-to-face contact with the secOnd layer by fastener means secured to the wooden strakes in the first layer.
