CLAIMS

1 . An insulation composition in the form of a paste that will harden after application, the paste comprising: a binder, an aerogel and a hardener, wherein the dispersion of the aerogel within the paste is such that the paste has a thermal conductivity of 30mW/m2k or below.

2. An insulation composition as claimed in claim 1 , wherein the density of the paste is not substantially different to the density of the aerogel prior to mixing.

3. An insulation composition as claimed in claim 2, wherein the aerogel, prior to mixing, has a density of approximately 180-190kg/m3.

4. An insulation composition as claimed in any of claims 1 to 3, wherein the binder comprises an aqueous binder.

5. An insulation composition as claimed in claim 4, wherein the aqueous binder is an acrylic binder.

6. An insulation composition as claimed in any of the preceding claims, wherein the binder further comprises a foaming agent.

7. An insulation composition as claimed in any of the preceding claims, wherein the binder further comprises a strengthening fibre.

8. An insulation composition as claimed in claim 7, wherein the strengthening material is chopped glass fibre.

9. An insulation composition as claimed in any of the preceding claims, wherein the hardener comprises a resin and an activator.

10. An insulation composition as claimed in any of the preceding claims comprising the following components:

56%-59% by weight of binder;

35%-38% by weight of aerogel;

5%-7% of by weight of hardener.

1 1 . An insulation composition as claimed in claim 10 comprising the following components:

56.34%-58.3% by weight of binder;

35.87%-37.56% by weight of aerogel;

5.83%-6.1 % by weight of hardener.

12. An insulation composition as claimed in claim 10 or claim 1 1 , wherein the hardener comprises between 76% - 77% resin and between 23%-24% activator.

13. An insulation composition as claimed in claim 12, wherein the hardener comprises 76.92% resin and 23.08% activator.

14. An insulation composition as claimed in any of claim 10 to 13, wherein the binder comprises the following components:

61 %-67% by weight of acrylic binder;

3%-5% by weight of foaming agent;

1 1 %-13% by weight of water;

1 1 %-13% by weight of strengthening material;

3%-5% by weight of flame retardant;

0%-3% by weight of crosslinker; and

0%-3% by weight of pigment.

15. An insulation composition as claimed in claim 14, wherein the binder comprises the following components:

61 .54%-66.66% by weight of acrylic binder;

3.85%-4.17% by weight of foaming agent;

1 1 .53%-12.5% by weight of water;

1 1 .53%-12.5% by weight of strengthening material;

3.85%-4.17% by weight of flame retardant;

0%-3.85% by weight of crosslinker; and

0%-3.85% by weight of pigment.

16. A method for forming an insulation composition, in the form of a paste, the method comprising the following sequential steps:

a) mixing an acrylic binder with a foaming agent to form a foamed product;

b) mixing the foamed product with an aerogel and water to form a paste; and

c) mixing the paste with a hardener.

17. A method as claimed in claim 16, in which step a) further comprises mixing a crosslinker with the acrylic binder and foaming agent.

18. A method as claimed in claim 16 or claim 17, in which step a) further comprises mixing a strengthening material and/or a flame retardant with the acrylic binder and foaming agent.

19. A method as claimed in any of claims 16 to 18, wherein step c) comprises the following sequential steps:

ci. mixing the paste with a resin; and

cii. mixing the combined paste and resin with an activator.

20. A method as claimed in any of claims 16 to 19, wherein a pigment is added to the mix to provide a visual indication of sufficient mixing.

21 . A method for using an insulation composition, as claimed in any of the preceding claims, comprising the steps of:

a) mixing the paste with an activator;

b) applying the paste to a substrate; and

c) allowing the paste to dry.
