Windows and Doors

Frame Reinforcement

Strong, light, and thermally non-conductive, composite materials can be used to reinforce window and door frames. Composites’ glass fiber reinforcement makes for excellent performance in high-load conditions and ensures high functional value and durability of windows and doors. Unlike steel frames, composites do not form thermal bridges, reducing heat loss; composite reinforcement is also just one quarter the weight of steel, which makes larger windows and doors easier to handle.

Eaves

Eaves prevent rainwater from flowing down the wall, and are often used to protect wood-framed windows. Composite materials are durable and easily machined, making them ideal for eaves. We make eaves to the customer’s order, with custom mold-cast shapes, delivered either as a semi product for further processing by the customer, or finished and painted according to the customer’s needs.

Residential Anchoring Elements

PREFEN FRP L profiles are strong, light, and thermally non-conductive, which makes them attractive as window and door frames in passive homes. Low-thermal-bridging composite anchors can also be used for gates and blinds. Aside from the standard L profile, longitudinally-cut U beams can also be used, with the advantage of a wider selection of sizes.
