Thermally insulative spacer and methods involving use of same
A spacer for use in spacing a cladding component from a building component has a support member, a base spaced apart from the support member, the base having a contact surface facing away from the support member, a web connected between the support member and the base, and a guide configured to locate the cladding component on the support member. A plurality of the spacers can be used by resiliently deforming them to accommodate and retain by restorative bias force a corresponding plurality of portions of the cladding component. Thereafter, the spacers are secured to the building component.
1. A spacer for use in spacing a cladding component from a building component, the spacer comprising:
a support member;
a base spaced apart from the support member, the base having a contact surface facing away from the support member, and the support member having a support surface facing away from the base;
a web extending between the support member and the base; and
a resiliently displaceable clip provided on the support surface of the support member and configured to retain the cladding component on the support member;
the resiliently displaceable clip comprising a flange configured to retain the cladding component against the support member on the support surface, at least a portion of the flange being resiliently displaceable away from the support member, the resiliently displaceable portion of the flange comprising a projection, the support member comprising a recess on the support surface, the recess being positioned opposite to and spanning the projection.
2. The spacer of claim 1 wherein the spacer comprises a fibre reinforced polymer.
3. The spacer of claim 2 wherein the spacer comprises fibreglass.
4. The spacer of claim 1 wherein the support member, base, web and resiliently displaceable clip are features of a pultruded profile section.
5. The spacer of claim 4 wherein the support member is elongate, and wherein the resiliently displaceable clip provides a stop parallel to one of the long sides of the support member.
6. The spacer of claim 1 wherein the resiliently displaceable portion of the flange is resiliently displaceable away from the support member in a direction generally normal to the support member.
7. The spacer of claim 6 wherein the resiliently displaceable clip comprises a flexure bearing connected to the flange, the flexure bearing allowing the resiliently displaceable portion of the flange to be resiliently displaced away from the support member.
8. The spacer of claim 7 wherein the resiliently displaceable clip comprises a U-shaped flexural member adjacent to the support member, the U-shaped flexural member comprising the flange and the flexure bearing.
9. The spacer of claim 1 wherein the support member comprises an aperture defined through it.
10. The spacer of claim 9 wherein the resiliently displaceable clip is configured to locate the cladding component over the aperture defined through the support member.
11. The spacer of claim 10 wherein the base has an aperture defined through it, and when the contact surface abuts the building component, the apertures defined in the base and the support member define a fastener path normal to the building component.
12. The spacer of claim 1 wherein the spacer is comprised of a low thermal conductivity material.
13. The spacer of claim 1 wherein the at least a portion of the flange that is resiliently displaceable away from the support member comprises a free end of the flange.
14. The spacer of claim 13 wherein one or both of an inward edge and an outward edge of the recess are smoothly beveled.
15. An assembly for use in spacing a building component and a cladding component, the assembly comprising:
a spacer having:
an elongate support member,
a base spaced apart from the support member, the base having a contact surface facing away from the support member, and
a web connected between the support member and the base; and
a resiliently displaceable clip adjacent the support member of the spacer, the resiliently displaceable clip configured to retain the cladding component relative to the spacer and to provide a stop perpendicular to one of the long sides of the support member, the resiliently displaceable clip comprising:
a body generally parallel to the support member, and
a flange spaced apart from the body, wherein the flange comprises a tab extending from the body and folded over the body along a fold perpendicular to one of the long sides of the support member,
wherein the support member, base and web and are features of a pultruded profile section.
