Thermal and acoustic performance of wood cement blocks
Valeur Energie, the magazine for renewable energies and alternative solutions, visits the Fixolite Belgium plant. A material used in post-war reconstruction, particularly in Germany, wood cement has been proving its worth for over 75 years. Produced since 1945 in Belgium, near Charleroi, Fixolite's wood-cement blocks were an early response to the need for... Read more →

Study of wood cement
This study is the result of a thesis by Marie Lamalle, Civil Engineer at the University of Liège, Belgium. Summary Wood concrete is a relatively recent material that is part of the current trend towards the use of bio-sourced materials in construction. This composite, made from a mixture of cement, wood chips and... Read more →

Roller shutters: inside or outside choice
Roller shutters are a practical and attractive solution for protecting and insulating windows. They offer increased security, better thermal insulation and protection from the sun. One of the technical choices to consider when installing roller shutters is the type of winding: external or internal. Each of these choices... Read more →

Passive house: how thick should the insulation be?
To achieve a thermal resistance of 6.5 m²-K/W in the walls (passive house), different thicknesses of insulating materials can be used, depending on their coefficient of thermal conductivity (λ). Here are some examples of insulating materials commonly used in construction and the thicknesses required to achieve this thermal resistance value. Material Lambda λ (W/m-K) Thickness... Read more →

Understanding insulation: Lambda, R and Uc
Insulation is a key element in the construction and renovation of buildings. It plays a crucial role in thermal comfort and energy efficiency. Among the various criteria used to assess the performance of an insulating material, two parameters are fundamental: the coefficient of thermal conductivity, often called the lambda coefficient (λ), and the resistance...
