b"2Description of specimen 2.1General The sponsor identified the specimen as a 45-degree pitched steel framed roof, clad with Delta Panels that measured nominally 2000-mm wide x 1550-mm deep that incorporated a 150-mm wide x 50-mm thick valley gutter located 450-mm from the right barge edge of the exposed face. Supporting construction The Delta Panels roof system was fixed to a DeltaTrim TPC test frame (TPC-R011) that measured 2040-mmwidex880-mmdeepx1590-mmhighatthebackand480-mmhighatthefront, fabricated using 65-mm x 65-mm SHS, 50-mm x 50-mm x 3-mm thick angled base and 1.2-mm BMT Beam cap (200-BEAM) located at the top, as shown in drawing number TPC-R011', dated 30 May 2023, by Delta Panel. The test frame was lined on both sides and the bottom with 6-mm thick fibre cement sheeting (TPC-R009 and TPC-R013) and a 100-mm thick DeltaCool -TPC insulated panel wall at the front. Specimen Details The roof was fabricated from three 100-mm thick DeltaTrim-TPC panels cut to 1550-mm length, the centre of the roof used a full width panel measuring 1000-mm wide (DeltaTrim-TPC Opp Cut), and twopartwidthpanelsmeasuring400-mmwide(DeltaTrim-TPCLHCut)and450-mmwide (DeltaTrim-TPC RH Cut) were used on the left and right hand edges of the roof respectively. The DeltaTrim-TPC panels comprised a thermosetting phenolic composite core (TPC) with a stated density of 38-42 kg/m3. The core was bonded on both sides to 0.6-mm thick roll formed steel skins using two-part polyurethane adhesive, the underside of the panel was flat, and the top steel skin had a Trimdeck profile, as shown in drawing DeltaTrim-TPC Opp Cut dated 17/01/2018 by Delta Panels.The bottom edge of the DeltaTrim-TPC panels were protected with profiled 1.2-mm thick roll formed steel skin DeltaTrim Fascia flashing (TPC-003) fixed with 13g x 25-mm self-drilling steel screws at 200-mm centres , and the exposed roof ribbing edges were covered with Delta TrimEnd Caps (TPC-R015) that were fully sealed with Boss FireSilicone-EMA sealant. The DeltaTrim-TPC panels were fixed to the steel frame using TEK 14 x 175 Hex screws and cyclone clips. All the joints on the underside of the roof were filled with a bead of FireSilicone-EMA sealant. The left and right barge edges of the roof were fitted with x 0.6-mm thick roll formed profiled steel skin DeltaTrim 100-mm side barge trims ( TPC-R006 and TPC-006-RH) fixed with TEK 14 x 175 Hex screws at 200-mm centres. The right side of the roof incorporated a 150-mm wide valley gutter located 450-mm from the right barge edge. The valley gutter consisted of a 50-mm thick x 150-mm wide mineral wool core with a stated density of 38-42 kg/m3 covered on the top side with a 30-mm x 50-mm 150-mm wide x 0.6-mm thick roll formed steel skin (TPC-R005) fixed with Tex screws at 200-mm centres and a 230-mm wide x 0.6-mm thick roll formed steel skin Valley gutter flashing ( TPC-R010) on the underside fixed with stainless steel rivets at 200-mm centres and the edges covered with FireSilicone-EMA sealant. Located at the ridge of the roof was a x 0.6-mm thick roll formed profiled steel skin ridge cap (TPC-R014) fixed screws. All exposed gaps between theDeltaTrim-TPC panels and the ridge cap and the fibre cement sheeting on the sides were filled with a bead of FireSilicone-EMA sealant. The roof specimen was fitted with a 120-mm wide x 140-mm high standard steel roof gutter. FSZ 2411 | page6 of 40"
