External Weather Face Multi-wall polycarbonate sheet 1,000mm wide with an external trapezoidal profile. The external face has a co-extruded UV protection.

Tapes / Sealants Factory-applied breather tape is applied to either end of the polycarbonate boxes to reduce the risk of condensation and prevent ingress of moisture and insects during transportation and delivery, keeping rooflights clean and optimising performance. Kingspan Day-Lite Trapezoidal Rooflight (KS1000 DLTR 1.0) has two runs of PE foam tape, one at each side.

Spacers Factory or site applied PVC spacers need to be positioned at purlin locations. Note: No spacers required when fitting with 40 mm QuadCore KS1000RW Roof Panel.

Side Laps Kingspan Day-Lite Trapezoidal Rooflight (KS1000 DLTR 1.0) should side lap on both sides with the QuadCore® KS1000RW Roof Panel, and not another rooflight product. All external side laps are weather sealed along the full length with unbroken runs of 6 mm x 5 mm butyl rubber sealant applied to the weather side of the stitching screw. Rooflights are supplied with a continuous stitching plate to the side lap crown to facilitate side lap stitching.

All external end laps are 75mm. Single run of 50mm x 8mm Kingspan Class A end-lap seal fitted with co-laminate/’U Side’ facing up. Rooflights supplied with end lap stitching plates, located in each minor valley to facilitate end lap stitching. Rooflight end laps using a ledger plate positioned at the rooflight end lap (1,100 mm long with 120 mm bearing face), so that all main fasteners are fixed through the ledger plate. Kingspan Day-Lite Trapezoidal Rooflight (KS1000 DLTR 1.0) should always end lap top and bottom with a QuadCore® KS1000RW Roof Panel, and not another rooflight product. We recommend that both top and bottom end laps for the rooflight are offset from the panel to panel end laps in adjacent panel runs.
