All Roval Aluminium sills are available in various standard sizes with various surface treatments and in virtually all RAL colours. The standard types can be produced in almost any non-standard size. Roval also offers custom-made options in a wide range of sizes and appearances.
We have developed special bulkheads for our aluminium sills which ensure the watertight connection of the sill, ideal for outside wall insulation for example. The bulkhead diverts the water so there are no leak marks or cracks in the façade as a result of residual moisture. As a result, the façade does not have to be cleaned or repaired later on. A simple, smart and cost-saving solution.
