<p>A fitting for a cavity wall within a building includes an elongate member adapted to be supported within the cavity wall. The fitting has two adjacent limbs formed with holes along its length, to allow insulation to pass into an interior of the fitting. Two adjacent limbs form a V-shape channel extending along the top of the fitting when installed, to collect and direct water to the ends of the fitting and out through the boundary wall of the cavity. The fitting has a cross-shaped cross-section, and can be placed in the cavity retrospectively. The cross-shape of the fitting is provided almost flat when dispensed from a reel and when entering the cavity, then springs into the cross-shaped cross-section when the elongate member is straightened in the cavity, to fit tightly within the cavity. The fitting can be inserted into the cavity wall from inside or outside the building.</p> |
