Träfönsterkarmar

Träfönsterkarmar are wooden window frames that surround and hold the window sash in place, forming the structural interface between a building and the window unit. They provide support for the glazing, help define the opening, and contribute to the overall aesthetics of the façade.

Materials used for timber frames vary. Common softwoods such as pine, spruce, and fir are frequently chosen for their workability and price, while hardwoods like oak or meranti may be used for added durability. Frames can be solid timber or built from laminated elements, and many are offered as clad windows with a weather-resistant outer layer (for example aluminum or vinyl cladding) while retaining a timber interior. Finishes typically include paint or stain to protect the wood and enhance appearance. Proper detailing, insulation, and sealing are essential to minimize heat loss and moisture intrusion.

Performance is influenced by species, workmanship, glazing, and sealants. Timber provides natural insulation and a warm aesthetic but is susceptible to moisture, rot, and insect damage if not properly protected. Regular maintenance—repainting or resealing and inspecting for gaps, leaks, or warped sections—extends lifespan. Modern timber frames often incorporate energy-efficient glazing (such as double or triple glazing) and improved weather sealing to meet contemporary standards.

Durability and sustainability are key considerations. With adequate care, timber frames can last several decades, and wood is a renewable resource when sourced from responsibly managed forests. Timber windows are valued for repairability and classic appearance, though they usually require higher ongoing maintenance and upfront cost compared with some alternatives.
