For reducing the energy use of buildings, application insulation materials can be a possible solution to improve efficiency. However, with continuously tightening regulations, thicker and thicker insulations should used (e.g., up to 20–25 cm in Hungary about 40–50 Nordic countries) to fulfil directives. In past decades, developmental research started focus on both decreasing the thickness d...

In this study, the use of expanded polystyrene and perlite as lightweight aggregates for preparation geopolymers is tested. The geopolymers’ performance was evaluated through physical, mechanical thermal testing. Polypropylene fibers were used reinforcement agents, while long-term durability assessed though repeated wet–dry freeze–thaw cycles sorptivity tests. results showed that introduction i...

The EU “Fit for 55” legislative package provides the introduction of regulations enabling achievement emission reduction target by 55%. As part necessary actions, it is to increase energy efficiency existing buildings. To achieve this, there are plans pace modernization buildings, from 1% 3% buildings annually 2030. However, this must be done with respect principles sustainable development, cir...
