Code 4 home - cavity insulation

100mm of Kingspan Thermawall® TW50 has been specified for the cavity wall on the Code 4 home. The total cavity size is 150mm. Kingspan Thermawall® TW50 is faced on both sides with a low emissivity composite foil which is highly resistant to the transmission of water vapour. This reflective, low emissivity surface effectively doubles the thermal resistance of the cavity in which the board is placed.

The Core - The core of Kingspan Thermawall® TW50 is manufactured from trademarked Nilflam® technology (a high performance CFC/HCFC–free polyisocyanurate (PIR) based formulation). Kingspan Thermawall® TW50 has a typical density of 32 kg/m3.

CFC/HCFC–free - Kingspan Thermawall® TW50 is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).
