Construction
The construction is made of Douglas fir. The reddish heart wood of the Douglas fir contains resin and oils that are resistant against fungus and insect infestations. We use technically-dried Douglas fir which, depending on length, is partly weatherproofed by finger jointing. This type of wood features high surface hardness. Fissures, branches and twists reflect the natural materials used.
If Douglas fir is not treated with varnish, a glossy grey-silver patina forms over time. It protects the built structure from environmental challenges, and you from time-consuming wood maintenance.
Color treatment
The wooden parts of this building kit are not color treated. If building kits of Douglas fir are assembled without chemical wood protection, no further treatment than regular cleaning of the patina with water is required.
If the natural texture of the wood is to be maintained, regular application of a protective coating is recommended. All-round coating should be applied prior to assembly. First apply wood primer. Then apply an intermediate and a finishing coat of premium wood varnish or paint to protect against color change and damage. Calculate service intervals of about 4-5 years, prior to the appearance of visible damage. Follow the processing guidelines of the varnish manufacturer.
Roofing
Roofing consists of stable, 16 mm-thick polycarbonate twin-wall sheet. The top face is provided with a UV-reflecting layer. It is attached with a high-quality aluminium profile with EPDM lip-seals.
Bracing
The building kit contains mounting brackets of galvanized flat steel including anchor bolts for attachment to the site-built foundation. They ensure secure connection to the subsurface.
