  1. 1. Building Retrofit using Vacuum Insulation Panels: Hygrothermal Performance and Durability

    Författare :Pär Johansson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory; retrofitting; interior insulation; listed building; field study; exterior wall; brick wall; numerical simulation; wooden beam ends; measurement; vacuum insulation panel; transient plane heat source; exterior insulation;

    Sammanfattning : Many old buildings have unsatisfactory thermal performance compared to the standards of today. One way to increase the thermal performance is to add thermal insulation to the building envelope. However, many old buildings are listed and considered to be valuable for historical and esthetic reasons. LÄS MER

  2. 2. Condensation and frost formation in fibrous thermal-insulation materials

    Författare :Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER

  3. 3. Cellulosic Thermal Insulation with Improved Water Resistance and Fire Retardancy

    Författare :Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Bio-based; Cellulosic; Fire retardant; Thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

  4. 4. Cellulose-fiber-based thermal insulation materials with fungal resistance, improved water resistance and reaction-to-fire properties

    Författare :Chao Zheng; Monica Ek; Dongfang Li; Lars Wågberg; Folke Björk; KTH; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; biorefinery; birch bark; cellulose; reaction-to-fire properties; fungal resistance; thermal insulation; water resistance; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Thermal insulation materials made from natural fibrous materials, such as cellulose fibers, have advantages over others from a sustainability point of view. However, cellulosic materials are generally prone to mold and absorb moisture, and these have negative effects on the insulation properties, the durability of insulation materials, and interior air quality.

  5. 5. Retrofitting of old Exterior Wall with Vacuum Insulation Panels: Measurements of Thermal Properties, Moisture Performance and Practical Considerations

    Författare :Pär Johansson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hygrothermal sensor; listed building; transient plane source; retrofitting; indoor moisture supply; vacuum insulation panel; hygrothermal simulation; exterior wall;

    Sammanfattning : The building industry is facing one of its most challenging tasks ever. Until 2050 the energy use for heating of buildings should be decreased by 50% which means a large part of the building stock have to be retrofitted to become more energy efficient. One of the possible solutions is to add thermal insulation to the exterior wall of the buildings. LÄS MER
