TEK Building System Panel Data
Resistance to Airborne Sound
Field tests to BS EN ISO 140-4: 1998 (Field measurements of airborne sound insulation between rooms) on separating walls, externally faced with 12.5 mm plasterboard, 19 mm gypsum planks and 9.5 mm plasterboard to each Kingspan TEK® Building System wall panel, achieved an average sound reduction of 58 dB (DnT,w (C;Ctr) 58 (–3; –7) dB). A laboratory test on a single wall panel with no internal dry-lining achieved a sound reduction (Rw) of 31 dB. When adopting the use of super dried timber frame party walls, the guidelines contained within the Robust Standard Details would be followed.
The λ-values and R-values quoted are based on accelerated ageing for 25 weeks at 70°C, in line with the methods used in the new European standard BS EN 13165: 2001 (Thermal insulation products for buildings – Factory made rigid polyurethane foam (PUR) products – Specification). Comparison with alternative products may not be appropriate unless the same procedures have been followed.
Thermal conductivity (λ-value) of the OSB/3 component of Kingspan TEK® Building System panels should be taken as 0.13 W/m.K. The thermal conductivity of the insulation core of Kingspan TEK® Building System panels is 0.023 W/m.K. Thermal Resistance Kingspan TEK® Building system panels have a thermal resistance (R-value) at a maximum of 5.100 m2.K/W. It is calculated by dividing the thickness of each component (expressed in metres) by its thermal conductivity and adding the resultant figures together.
