Abstract
Abstract A method of constructing thermally insulated cavity wall in a quick manner with relatively unskilled labor comprises laying bricks, blocks or the like in successive courses without mortar or adhesive therebetween and injecting a foamable material into the cavity progressively as the wall is constructed. Joint spaces may be provided between adjacent blocks in each course so that the foamable material may bond to for example plaster board applied to the inner wall portion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
102 words
Method of constructing a cavity wall having first and second spaced single wall portions with a cavity therebetween, said method comprising laying a plurality of building blocks in successive courses in block to block contact without a bonding material therebetween to construct at least said second wall portion and form said cavity wall, and, after each successive temporarily uppermost course of blocks is laid, injecting said foamable material into said cavity in a quantity sufficient when foamed to partially fill the portion of said cavity lying within the temporarily uppermost course of blocks prior to laying the next successive temporarily uppermost course.
Claim 2
Dependent Claim
102 words
Method of constructing a cavity wall having first and second spaced single wall portions with a cavity therebetween, said method comprising laying a plurality of building blocks in successive courses in block to block contact without a bonding material therebetween to construct at least said second wall portion and form said cavity wall, and, after each successive temporarily uppermost course of blocks is laid, injecting said foamable material into said cavity in a quantity sufficient when foamed to partially fill the portion of said cavity lying within the temporarily uppermost course of blocks prior to laying the next successive temporarily uppermost course.
Claim 3
Dependent Claim
35 words
The method as claimed in claim 1 wherein said quantity of foamable material is sufficient when foamed to fill one fourth of the portion of said cavity lying within said temporarily uppermost course of blocks.
Claim 4
Dependent Claim
25 words
The method as claimed in claim 1 wherein additionally a coating is applied to at least one outer face of said wall after construction thereof.
Claim 5
Dependent Claim
53 words
The method as claimed in claim 1 wherein joint spaces are left between at least some of the adjacent blocks in any one course and wherein a board is applied to the outermost face of said blocks whereby said foamable material enters said spaces and bonds said blocks and board to each other.
