Not sure which material to choose?

Pine

At Sparwindows we you will find resposible produced energy-efficient quality external doors, produced in slow-growing Nordic pine from responsible forestry. The pine wood has a heartwood content of at least 90% and is finger-cut to ensure the best possible quality and finish. Want to learn more about the excellent properties of pine wood windows and doors follow the link below.

Alu-clad pine

Whether you choose ordinary pine elements or aluminium clad elements depends entirely on your personal taste and type of dwelling. Aluminium clad elements combine the best properties of wood with aluminium’s weather resistant exterior. In addition, aluminium clad doors do not need continuous maintenance and are therefore a time-saving alternative.
