This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.

Värmebehandling av virke, som metod för att modifiera virkets egenskaper, är inte någon nyhet på marknaden. Attegenskaperna hos virke förändras då det utsätts för höga temperaturer har varit känt länge och flera metoder förvärmebehandlinghar utvecklats och industrialiserats. I Sverige har dock värmebehandlat virke inte slagit igenom på marknaden inågon större grad.Värmebehandlat virke tillskrivs en mängd förbättrade egenskaper jämfört med obehandlat virke, t~ex ökat motstånd motnedbrytning och ökad dimensionsstabilitet. Färgen på virket förändras också vid värmebehandling. Virket blir mörkare vilketgör det attraktivt som alternativ till populära träslag som inte växer i Sverige.
