Technology & Design GAULHOFER’s optimised glass-spacer solution – Thermostop ® and Thermostop® Plus keeps your home warm while preventing condensation from forming on the glass and rotting the wood. GAULHOFER’s ground-breaking wet-sealing technology with hand-smoothed UV resistant silicone keeps the glass joint tightly-sealed while allowing for the natural expansion and contraction of the materials used in the frame. An exclusive GAULHOFER innovation - Dampfstop®, protects the glass rebate from moist room air which keeps the glass composite dry and the sash wood looking its best. The result? An invisible life insurance for your window. GAULHOFER Audiostop® technology not only keeps out traffic noise it also further prevents the formation of condensation in the rebate area. Another GAULHOFER advantage. Window Handles GAULHOFER offers an extensive range of beautiful handles to complement, or contrast with, you Natureline wood windows.
