Window Specifications

  • Wood is pure nature for all the senses: beautiful, warm, fragrant and especially pleasant to touch. The same applies to wood windows from Gaulhofer, for which we have for the last 90 years exclusively used indigenous larch and spruce felled in the winter and from sustainably managed forests. Both are as natural and beautiful as they are sturdy and tough. Wind and cold are kept out and with an optimum UW-values and consumption of heating material and CO2 emission are lowered. Living comfort and cosiness, on the other hand, are multiplied many times over.

  • Handles

    RAL tested. HARMONY is a classic that satisfies many requirements. The window handle matches state-of-the-art architectural environments as well as windows for old half-timbered houses reproduced true-to-style. Its distinctive, charismatic contours and timelessly attractive appearance make their mark from the very first moment on. HARMONY is available in the colours bronze, champagne, RAL 80149 grey brown, RAL 9016 traffic white, silver and titanium.

    Tilt and Turn Mechnanism

    GAULHOFER 4-point-security provides comprehensive protection against break-in and other extraordinary stress. A minimum of four mushroom cam locks made from high-strength materials provide all-round fastening for your windows. Literally! A central locking system, (i.e. security roller cams and sash lifter) provide the basis for each set. You can add further MULTI single components based on the additional functions you require. To achieve the burglar-resistant version of your window units, use i.S security striker plates instead of the standard striker plates and arrange them according to the desired burglary-resistance grade.
