Kalzip Insulation 23
Kalzip Insulation 23 is a standard component for use in the Kalzip low U-value roof system. It is a high performance rigid polyisocyanurate (PIR) insulation board, introduced to give a second layer of insulation with low thermal conductivity.
Kalzip Insulation 23 is faced on both sides with a low-emissivity which is highly resistant to the transmission of water vapour in accordance with BS 4370-2: 1993.
Kalzip glass quilt insulation
Kalzip’s range of insulation products includes glass mineral wool quilt and rock and glass mineral wool slab with the newly available ECOSE™ Technology.
At the heart of Kalzip’s insulation products is a full range of Kalzip Insulation Plus materials which are high performance glass quilts offering extremely efficient thermal performance.
Products are fully compliant with the harmonised European Standard BS EN 13162 : 2001, are non-hygroscopic, non combustible to BS 476:Part 4, Class 0 and in accordance with BSI Quality Assurance Standard BE EN ISO 9002.
Environmental performance
Kalzip insulation products conserve energy and therefore assist in reducing demand for fuels for the heating and air-conditioning of buildings. As a result they reduce the emission of the major greenhouse gas – CO2.
The core of the PIR based formulation and all Kalzip insulation products are CFC/HCFC free with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than five.
Durability and recycling
When correctly applied Kalzip Insulation 23 has an indefinite life fully supporting the sustainable credentials of standard Kalzip standing seam systems. Kalzip insulation products can be reused or recycled at the end of the building’s life.
