Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
50 words
A free flowing cavity wall insulating material comprising a main mass of substantially spherical beads admixed with a 2. to 20% w/w (based on the total insulating material) of granules of the same or different material having a volume substantially different from and being dissimilar in shape from the beads.
Claim 2
Dependent Claim
50 words
A free flowing cavity wall insulating material comprising a main mass of substantially spherical beads admixed with a 2. to 20% w/w (based on the total insulating material) of granules of the same or different material having a volume substantially different from and being dissimilar in shape from the beads.
Claim 3
Dependent Claim
17 words
An insulating material according to claim 1 wherein the beads are made of polyurethane or expanded polystyrene.
Claim 4
Dependent Claim
23 words
An insulating material according to claim 1 or 2 wherein the beads have an average diameter of between 2 mm and 5 mm.
Claim 5
Dependent Claim
21 words
An insulating material according to any one of the preceding claims wherein the granules are of a random or regular shape.
Claim 6
Dependent Claim
20 words
An insulating material according to claim 4 wherein the granules have a shape selected from rectangular, plate-like, saucer-shape and saddle-shape.
Claim 7
Dependent Claim
39 words
An insulating material according to claim 5 wherein the granules are formed as clusters or agglomerates from the main mass of beads by injecting small, discrete quantities of an adhesive into the beads over intervals of space and/or time.
Claim 8
Dependent Claim
37 words
An insulating material according to any one of the preceding claims 4-6 wherein the average volume ratio in respect of the surface area of an individual granule to that of an individual bead is greater than 5:1.
