Thanks to the design of their aluminium profiles, the glazed surface area of K-LINE doors and windows is 20% larger than their traditional counterparts. When they are closed, casements become invisible, as they are hidden behind the window frames, allowing much more light in.






K-LINE doors and windows, equipped with thermal breaks and double or triple glazing with reinforced insulation, deliver the highest thermal and acoustic insulation values, and have earned the highest certifications in the market, which are indisputable proof of their high quality and performance.

High thermal insulation, up to 0.76 Uh W/m2.K

High acoustic insulation from 30 to 44 dB (Rw = 48 dB )





K-LINE doors and windows are discreet and elegant, designed with stylized shapes and slender profiles.







K-LINE gives you 31 colours to choose from, with standard, matte and textured lacquered finishes, wooden and anodized finishes, with a bicolour option allowing you to have a different colour inside and outside, to personalize your home and integrate it in its environment.






Las puertas y ventanas K-LINE incorporan múltiples opciones de seguridad como cierres WK-1 (RC1) y WK-2 (RC2), sistemas antipalanca y vidrios antirrobo de alto rendimiento, para protegerte contra robos e intrusiones.
