Description
Insulating your house is definitely required these days, and biosourced insulation is great for coping with heat. Prespaglia offers a line of modular blocks of pressed straw for the construction sector. Four different types of blocks are proposed so far, and they are quick and easy to assemble.
The circular aspect is clear: straw is an agricultural waste product. It is usually used as animal bedding so processing it instead into a high value product such as insulation is a step forward.
The modular eco-blocks are made of straw, clay and pozzolan lime, making them entirely recyclable and biodegradable. They offer high levels of thermal-acoustic insulation and resistance to fire.

Main results
Advantages of using straw-based modular eco-blocks:
- zero CO₂ emissions (cold production system);
- energy consumption which is one third less than traditional solutions due to the good thermal characteristics that reduce heat dispersion;
- sound insulation above 50 decibels thanks to the mixture with clay;
- good anti-seismic solution (lightness and flexibility of the material);
- drastic reduction in labour (by 60-70%) and production costs.
