- Our wooden sash windows are made from treated engineered softwood pine (sill hardwood) or hardwood oak. Warping of the treated wood that we use
has been minimized to ensure long-term performance of our sash
windows. A long-term smooth operation of the wooden sash windows is a
standard. The wood is covered under our ten-year company guarantee.
- Various fully-factory finishes are available: more than 200 colors from RAL classic palette for a unique design of your sash windows.
