Service Integration / Internal Linings

Minimum 12.5 mm vapour check* plasterboard on 25 mm timber battens†. Minimum 12.5 mm vapour check* plasterboard on 19mm gypsum plank or 12.5mm plaster board.
   
The minimum plasterboard requirement may vary subject to statutory requirements for fire and acoustics. The need for electrical sheathing / conduit should be assessed in accordance with Building Regulations/ Standards and BS 7671: 2001
Minimum 12.5 mm vapour check* plasterboard fixed direct to the
Kingspan TEK® Building System.
 
   
   

Cladding Options

12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 25 mm (min.) vertical treated timber counter battens, timber boarding. U-value 0.20 - 0.22 W/m2.K 12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 25 mm (min.) vertical treated timber counter battens, tiling battens, tile changing. U-value 0.20 - 0.22 W/m2.K

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.

 
 

Typical Wall Constructions

12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 50 mm cavity, brickwork facing. U-value 0.19 - 0.21 W/m2.K. 12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 25 mm (min.) vertical treated timber counter battens, calcium silicate board with lightweight render coating. U-value 0.20 - 0.22 W/m2.K.
   
12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 25 mm (min.) vertical treated timber counter battens, proprietary brick slip system. U-value 0.20 - 0.22 W/m2.K. Kingspan Kooltherm® K18 Insulated Dry–lining Board. Non tenting breather membrane (e.g. Kingspan nilvent®, 25 mm (min.) vertical treated timber counter battens, calcium silicate board with lightweight render coating.
   
   

Roof Construction

12.5 mm vapour check* plasterboard on 25 mm timber battens†. Non tenting breather membrane (e.g. Kingspan nilvent®, 38 mm x 38 mm vertical treated timber counter battens, tiling battens and tiles / slates. U-value 0.18 - 0.20 W/m2.K 37.5 mm Kingspan Kooltherm® K18 Insulated Dry–lining Board. Non tenting breather membrane (e.g. Kingspan nilvent®, 38 mm x 38 mm vertical treated timber counter battens, tiling battens and tiles / slates. U-value 0.16 W/m2.K
   

† 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.
