Window Frame

The window frame itself plays a big role in energy efficiency. Wooden frames distribute heat evenly, last for decades, and are naturally CO₂-neutral. A smart and sustainable choice for any home.

Possible Materials

Wood is a renewable, low-carbon option widely used for window frames in Europe. It offers good thermal performance, a natural aesthetic and can be sourced locally. Common softwoods like pine and spruce provide an affordable standard solution, while hardwoods such as oak offer higher durability. Modern engineered woods, including laminated timber or Accoya, improve stability and weather resistance, making timber frames suitable for energy-efficient buildings.
