SonnenKlee construction straw combines the benefits of a natural building material with the requirements of modern construction projects.
Our Construction Straw Products:
Straw Bales
Suitable for new builds and renovations
For straw bale construction and timber frame construction: straw bales can be used as load-bearing elements or as a high-quality insulation layer. They create an excellent indoor climate, deliver strong thermal performance, and support sustainable building methods.
Why SonnenKlee Construction Straw
Unser Baustroh stammt aus regionaler Landwirtschaft, wird kontrolliert verarbeitet und erfüllt die Anforderungen professioneller Bauweisen – vom Einfamilienhaus bis zum anspruchsvollen Projekt.
01
Sustainable & regional
SonnenKlee straw is a renewable raw material from agriculture, mostly sourced locally. This helps reduce embodied energy, lower CO₂ emissions, and use a building material with an excellent environmental footprint — without long transport routes.
02
Natural & free from harmful substances
100% straw — with no synthetic additives or unnecessary chemicals. This creates a noticeably pleasant living environment and supports a healthy indoor climate, especially in bedrooms and living spaces.
03
Moisture-regulating & vapour-permeable
SonnenKlee straw can temporarily absorb and release moisture without immediately becoming “wet.” This supports dry, high-performing wall and roof assemblies when the components are designed to remain vapour-permeable.
04
Excellent insulation performance
SonnenKlee straw provides reliable insulation against both cold and heat. In winter, it keeps warmth inside the building; in summer, its high thermal storage capacity helps rooms stay comfortable for longer and improves heat protection.
05
Indoor comfort & well-being
Straw creates a noticeably comfortable indoor atmosphere. In suitable vapour-permeable wall systems, it helps buffer moisture, keeps wall surfaces warm, and improves acoustic comfort. The result is a balanced indoor climate — cosy in winter and pleasantly comfortable for longer in summer.
06
Cradle to Cradle & circularity
Straw is a natural, circular building material. When combined with suitable natural plasters, the wall system can be dismantled at the end of its service life and returned to the biological cycle — even for reuse in agriculture.
