STV + IKD Window Characteristic Features:

  • TO BE USED IN PASSIVE HOUSING !!!   
  • embedding depth – 82.5 mm    
  • window heat-transfer coefficient Uw from 0.73 W/m2K  
  • modern design; available in regular casement version  
  • advanced-technology solutions; additional antiburglar barrier 
  • no steel reinforcement of casement – filled with heat insulating foam IKD*  
  • casement stiffness is provided by the technique of the casement bonding and pane (STV*).
  • available in white

•    STV is an innovative method of the glazing unit durable bonding to casement with static-thermal tape which considerably improves thermal performance, statics and antiburglar rating of the window.


•    IKD is a solution where the profile main chamber is fully filled with the structural thermal foam which ensures unique thermal insulating and soundproofing performance of the window.
