The provision of a dedicated service void maintains the integrity of both the insulation and airtightness of the wall. The Kingspan ULTIMA™ panel jointing system maintains continuity of airtightness not only at panel-to-panel junctions but also at critical junctions with foundations, intermediate floors and roof. In whole-building airtightness testing Kingspan ULTIMA™ has consistently delivered permeabilities less than 2m3/m2.hr @ 50pa.  The air leakage barrier dressed into openings allows a simple tape seal to windows, doors and other wall penetrations.

The Kooltherm K-range is an extensive range of premium performance phenolic insulants for roof, wall and floor insulation.

Kingspan Kooltherm K112 Framing Board has a fibre-free rigid thermoset phenolic insulation core faced on both sides with a low-emissivity composite foil facing. By using Kingspan Kooltherm® the thickness of insulation included in external walls can be minimised and the floor space available for use increased.
Kingspan Kooltherm offers the following benefits:

• With a thermal conductivity of 0.018–0.023 W/m.K these are the most thermally efficient insulation products in common use.
• The thinnest commonly used insulation products for any specific U–value.
• Manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low  Global Warming Potential (GWP).
• The closed cell structure resists both moisture and water vapour ingress, a problem which can be associated with open-cell materials such as mineral fibre which can result in reduced thermal performance.
• Unaffected by air infiltration – a problem that can be experienced with mineral fibre and which can reduce thermal performance.
• Safe and easy to install – fibre-free core.
• If installed correctly, can provide reliable long-term thermal performance over the lifetime of the building.

Thermal bridging from external junctions has recently become an important factor in energy efficiency because the overall insulation and airtightness standards for UK homes are relatively high. To address this, ULTIMA™ demonstrates a level of performance that far exceeds SAP guidelines, achieving thermal bridging values of 0.03-0.04.

The Kingspan ULTIMA™ Building System exceeds the requirements of Approved Document B Volume 1 with regards to fire resistance when tested in accordance with BS EN 1365:1 1999 and achieved 49 minutes of structural integrity using a standard 15 mm plasterboard lining.

Independent fire assessment confirm that Kingspan ULTIMA™ would achieve 30 minutes of fire resistance using a 12.5 mm standard plasterboard lining. Should any element of your home require a 60-minute structural integrity, this can be achieved with a 15 mm fire-resistant plasterboard.
