Airtightness

The provision of a dedicated service void maintains the integrity of both the insulation an airtightness of the panels. The ULTIMA™ panel jointing systems maintains continuity of airtightness not only at panel to panel joints, but also at critical junctions with foundations, floors and roof.
In whole building airtightness tests, ULTIMA™ has consistently delivered permeability's less than 2m3/m2.hr @ 50pa. The Air Leakage barrier dressed into openings allows a simple tape seal to windows and doors.

Thermal Bridging

Continuity of the high performace Kooltherm™ Insulation internal lining, not only ensures the elimination of cold bridging within the ULTIMA™ panels, but also at critical joints including foundations, floors and roof. 

Fire Performance

The use of Kingspan Kooltherm™ Insulation as an overlay (minimum 25mm) within the ULTIMA™ Patented Insulated Structural Panels improves the structural integrity of the system in the event of a fire and complies fully with the requirements of the Building Regulations. ULTIMA™ has an independently tested fire resistance performance* of 30 minutes with only a single layer of 12.5mm plasterboard (minimum density 860 g/m3) fixed in accordance with the manufacturer’s instructions. Should 60 minutes fire resistance be required, this can be achieved with a single layer of 15mm Siniat Pregyflam board.
