    • Accelerated ageing and durability of double-glazed sealed insulating window panes and impact on heating demand in buildings 

      Asphaug, Silje Kathrin; Jelle, Bjørn Petter; Gullbrekken, Lars; Uvsløkk, Sivert (Journal article; Peer reviewed, 2016)
      A crucial property for double-glazed sealed insulating window panes is to maintain their thermal insulating properties and thus low U-values. However, degradation and thus subsequent reduction or loss of low-conductance ...

    • Hot Box Investigations and Theoretical Assessments of Miscellaneous Vacuum Insulation Panel Configurations in Building Envelopes 

      Grynning, Steinar; Jelle, Bjørn Petter; Uvsløkk, Sivert; Gustavsen, Arild; Baetens, Ruben; Caps, Ronald; Meløysund, Vivian (Journal article; Peer reviewed, 2011)
      Vacuum insulation panels (VIPs) are regarded as one of the most promising existing high performance thermal insulation solutions on the market today as their thermal performance typically range 5—10 times better than ...

    • Hot-Box measurements of highly insulated wall, roof and floor structures 

      Gullbrekken, Lars; Uvsløkk, Sivert; Kvande, Tore; Time, Berit (Journal article; Peer reviewed, 2016)
      The purpose of this study was to investigate how natural convection in air-permeable glass wool insulation affects the thermal transmittance in walls, roofs and floor structures. The results can be used to evaluate the ...

    • Improving Thermal Insulation of Timber Frame Walls by Retrofitting with Vacuum Insulation Panels – Experimental and Theoretical Investigations 

      Sveipe, Erland; Jelle, Bjørn Petter; Wegger, Erlend; Uvsløkk, Sivert; Grynning, Steinar; Thue, Jan Vincent; Time, Berit; Gustavsen, Arild (Journal article; Peer reviewed, 2011)
      Many of the Norwegian buildings from the 1960s–1980s with timber frame walls are ready for retrofitting. Retrofitting of these buildings with vacuum insulation panels (VIPs) may be performed without significant changes to ...

    • Kunnskapsstatus – Fuktbufring i materialer og påvirkning på energibehov 

      Asphaug, Silje Kathrin; Time, Berit; Thue, Jan Vincent; Geving, Stig; Gustavsen, Arild; Mathisen, Hans Martin; Uvsløkk, Sivert (ZEB Project report;22-2015, Research report, 2015)

    • Local loss coefficients inside air cavity of ventilated pitched roofs 

      Gullbrekken, Lars; Uvsløkk, Sivert; Geving, Stig; Kvande, Tore (Journal article; Peer reviewed, 2018)
      Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ...

    • Moisture in Multi-Layer Windows 

      Time, Berit; Uvsløkk, Sivert; Plsek, Dalibor; Gustavsen, Arild; Asphaug, Silje (Peer reviewed; Journal article, 2015)
      There is an increasing interest in development of coupled multi-layer window structures. This is to optimize thermal properties and to develop systems with a better climate protected solar shading system. The risk of ...

    • Vacuum Insulation Panels for Building Applications: A Review and Beyond 

      Baetens, Ruben; Jelle, Bjørn Petter; Thue, Jan Vincent; Tenpierik, Martin J.; Grynning, Steinar; Uvsløkk, Sivert; Gustavsen, Arild (Journal article; Peer reviewed, 2010)
      Vacuum insulation panels (VIPs) are regarded as one of the most promising high performance thermal insulation solutions on the market today. Thermal performances 3 to 6 times better than still-air are achieved by applying ...

    • 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 ...
