Wall U-values

  • Using the Kingspan TEK Building System complete walls can easily provide extremely low U-values between 0.10 W/ m²·K and 0.22 W/ m²·K.
  • Kingspan TEK is clearly bringing future building standards home today.

† An alternative to plasterboard on battens is two layers of 12.5 mm plasterboard with the inner layer being vapour check plasterboard*.
*Calculations in accordance with BS 5250: 1989 (1995) (Code of practice for control of condensation in buildings) will determine whether there is a requirement for a vapour control layer with the Kingspan TEK Building System. However it is always good practice to install a vapour control layer as buildings have a tendency to alter their psychrometric conditions (relative humidity) through change of use. This can be installed in the conventional manner, using 500 gauge polythene sheet, or by using vapour check plasterboard.

Roof U-values

Using the Kingspan TEK Building System complete roofs can easily provide extremely low U-values.

For roofs in dwellings with insulation in the slope of the roof (room in roof constructions) 0.20 – 0.16 W/m²·K are the current U-values required by the Building Regulations / Standards in the UK and Ireland.

Kingspan TEK Building System can clearly meet these requirements.

All U-values stated for the Kingspan TEK Building System are quoted for a complete element build up consisting of all layers involved in the detail, including the external and internal surface resistances and does not relate to the Kingspan TEK Building System panel on its own.

It is always advisable to undertake a condensation risk analysis in accordance with BS 5250: 2002 as the same time as performing the U-value. This will evaluate the likelihood of interstitial condensation.
