Quality - The most important principle
High Quality is the most important principle of Stommel Haus.
This high quality is achieved by using state-of-the-art CNC production methods combined with true craftsmanship. This is demonstrated by the design and manufacture of the unique Stommel Haus walls, ceilings and roof and the high precision achieved when building the houses on site.
Ralf Stommel, Managing Director of Stommel Haus says: "Only good material and well designed solutions allow us to build high quality and sustainable timber houses. 40 years of experience have taught us what is important:
- Polar spruce whose slow growth and fine annular rings make it so durable
- Selection of good quality timber
- Careful seasoning of the timber
- Using timber from the heart of the wood only
- Well specified wall design with high quality insulation
- A core principle is Constructive Wood Protection by design
- Inspection by a third party for production and erection according to the renowned German RAL certification mark."
The Wall
The Stommel Haus "Elementar" wall is an ingenious design consisting of layers of natural materials. The stud wall is built up using solid polar spruce timber, gypsum fibre and wood fibre panels, mineral fibre insulation with Knauf Ecose technology and an air cavity and a service cavity. The 34.85 cm thick wall provides extremely high insulation.
The wall can "breathe" and keeps the interior climate of the house in a perfect condition. We do not use any OSB panels, glue or membranes in the wall which could collect moisture. The natural property of the wood allows it to keep the air humidity inside the house at a perfect level and provides for the typical Stommel Haus "Feel Good" atmosphere - a trademark of Stommel Haus homes.
Unlike other timber house manufacturers, we use solid timber cut from the heart of polar spruce which is harvested only from certified forests north of the artic circle and seasoned in a complex process. There is no shrinking or twisting of the wood.
Ceiling and Roof
The ceiling and roof truss are built with visible rafters and purlins, the timber is joined durably and elegantly and achieves a pleasing design.
In order to join the ceiling with the frame of the house we use a conic dove tail joint which ensures an accurate fit of all parts of the construction while avoiding twisting and turning. The entire construction demonstrates true craftsmanship.
Manufacture and Build
The whole production process is constantly monitored by internal quality checks as well as independent inspection by third party experts. The highly regarded German RAL Certification Mark for production and build guarantee the best quality for the client.
Certification
We work according to German DIN and other building standards as well as the specific quality requirements of the RAL Certification Mark. Most of the German DIN Standards have equivalent European and British Standards. Stommel Haus is regularly controlled and monitored by independent institutions and receives the German "Ü-Zeichen" and "RAL Gütezeichen", which are well known Certification Marks of the German Building Industry.
