- Danish design / German engineering

- Made to measure

- 56mm per door frame giving a maximum frame to frame width of 117mm

- Top hung design uses no guide rail and makes threshold cleaning easy

- Air permeability EN 12207 - Class 4 at +/-600 Pa

- Watertightness EN 12208 - Class E1200

- Heat treated beech (German)- with durability equal to teak - Class 1

- No need for repainting for 25-50 years in normal conditions

- Ironmongery of the highest marine grade acid proof stainless steel (316-A4).
