• The Effect of Repeated Moisture Cycles on the Air Tightness of Traditional Clamped Vapour Barrier Joints 

      Geving, Stig; Norvik, Øyvind; Gullbrekken, Lars (Journal article, 2019)
      In this study it has been investigated whether and to what extent, repeated moisture cycles affect the airleakage through clamped overlap joints in the vapour barrier layer. Use of clamped joints is a traditionalway to ...
    • Ventilated wooden roofs: Influence of local weather conditions-measurements 

      Gullbrekken, Lars; Kvande, Tore; Time, Berit (Journal article; Peer reviewed, 2017)
      This study investigates the influence of temperature and air velocity conditions on ventilation and condensation in spring, summer and autumn periods inside a ventilated cavity in a full-scale wooden roof construction. The ...
    • Wind pressure coefficients for roof ventilation purposes 

      Gullbrekken, Lars; Uvsløkk, Sivert; Kvande, Tore; Pettersson, Kaj; Time, Berit (Journal article; Peer reviewed, 2018)
      Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load. The aim of this research is to investigate wind pressure coefficients on a test house located in Norway in order to pave the ...
