TWO-STOREY HOUSING WITH BRICK AND RENDERED WALLS

WORKING DETAILS / NEW ISLINGTON

The construction of the housing scheme uses relatively conventional materials, yet achieves an Ecohomes 'Excellent' rating. The at roofs are covered with a sedum roof mat; the brick and block walls are partly filled with 50mm polyurethane insulation; and the ground oor is of beamand-block construction. Where the link block is single storey, the roof is covered with a timber deck to create a terrace.

The glazing, set in hardwood frames, complies with Secured by Design security recommendations, with a 6mm toughened-glass outer pane, 16mm cavity and 6mm inner pane to first-oor windows; and 6mm laminated glass, 16mm cavity and 6mm inner pane to ground-floor windows.

To relate to surrounding buildings, brickwork colours vary from house to house; the link blocks have off-white render. The external-wall and party-wall junctions were generally made with sealant on compressible joint filler, with sealant on backing rods for brick/render to window-frame joints. The edges of the render were fitted with stop beads.

A range of sealant colours - generally a slightly darker shade of grey - is used at brickwork movement joints and junctions. A lighter grey is used at windows within the rendered link blocks. The window frames are painted in three shades of grey.
