Abstract: A flexible, elongate barrier comprising relatively rigid barrier portions connected by elastomeric joints is introduced slidingly into the cavity of a cavity wall and sealed to the outer leaf of the wall by introducing a portion of the barrier into a slot cut in the inner surface of the wall and/or by providing a water resistant composition which may be injected into the slot. The barrier may form an X or V shaped configuration defining a channel from which water is discharged via drains from the cavity. The barrier portions may be arranged in a flat configuration when the barrier is stored on a reel and moved through a deployed configuration to an installation configuration against the resilient bias of the joint so that they spring out to the deployed configuration to conform to the width of the cavity after installation.

Abstract: 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.

Abstract: A fitting (1) for a cavity wall within a building comprises elongate member adapted to be supported within the cavity wall, two adjacent limbs being formed with a plurality of holes (4) extending along the length of the fitting so as to allow insulation into the fitting (1) the other adjacent limbs form a V-shape channel top of the fitting when installed, to collect water and to direct it to the ends of the fitting and out through the boundary wall of the cavity wall. The fitting (1) is of Cruciform cross-section. The fitting is placed in the cavity retrospectively. The Cruciform is provided almost flat from a reel when entering the cavity, then springs into the cruciform cross-section when the elongate member is straitening in the cavity, and fit tightly within the cavity. Further, the fitting can be inserted into the cavity wall from inside the building or outside the building.
