Choice of Interior Timber for Andersen sash windows

Oak Sash Windows

Our oak sash windows are made from this northern hemisphere hardwood which is very strong, durable, and resistant to insect and fungal attack. Oak has been used in construction for hundreds of years, both external and internal use. The lovely grain can be seen in our Andersen oak sash windows, which are made using wood from managed forests.

Maple Sash Windows

Our maple sash windows are made from a Canadian variety which is particularly hard, and often used in interior and exterior construction. These Andersen maple sash windows are made using Maple from managed forests.

Pine Sash Windows

Pine is a popular engineered softwood, but our pine sash windows are suitable for external use due to them being treated. All of our pine comes from managed coniferous forests. Our Andersen Pine sash windows are a great low-cost option.

Our Andersen windows are virtually maintenance - free (the equivalent of PVC), and require no painting. The internal perimeter is rebated to accept a tongue for lining out. Double glazed units have a 20 year warranty against breakdown which is transferable to future owners. Mortise-and-tenon joints prevent sag and ensure smooth operation of windows. All glazing is self cleaning and is delivered with a translucent film to protect it during building works or decoration. Windows tilt inward for cleaning. A selection of high quality classic or contemporary window furniture is also offered. We supply a range of bathroom, bedroom, living room and kitchen windows. Insect screens are also available.
