Material
Sonnenland A5
Sonnenland® is a registered trademark for a very high quality canvas made in Germany and used by car manufacturers worldwide for their
original equipment, including Porsche and Mercedes
This is highly UV and abrasion resistant.
The canvas's trademark is a fish bone or criss-cross pattern on its back.
Sonnenland only refers to the material, i.e. yard goods, and not the finished hood
Sonnenland canvases comprise of three layers:
Outer layer: is made of Dralon, which is a woven acrylic fibre (polyacrylonitrile). This fabric is highly UV and abrasion resistant.
Intermediate layer: The intermediate rubber layer comprises of a waterproof synthetic
rubber material. This removes the need for any additional waterproofing. This is why
we do not offer waterproofing products and advise our customers against using any
such products offered on the market.
Inner layer: The backing used to be made of cotton (Sonnenland Classic) and is now
made of polyester
100% waterproof:
We use a kind of thread that has been specially developed for soft tops that swells up when wet and consequently effectively seals the seam holes. All of the seams on the hood are furthermore treated with a fabric seam sealer to ensure that they are 100% waterproof.
Just as with the original hood, we use a special machine to weld a tape over the seams on the inside of the hood.
No cleaning or waterproofing required:
There will not be any need for expensive cleaning or waterproofing agents. Sonnenland® canvas is a 3-ply material and has a rubber middle layer. The rubber layer keeps water from penetrating through the roof.
What's included:
Ready-to-fit soft top without frame, seals and headliner - which are to be reused.
