The thermal break of the G.U-thermostep threshold considerably reduces the heat flow at the bottom of timber and PVC lift-slide and lift-tilt-slide units, thus achieving noticeable energy saving. Thermally broken tubular threshold for lift-slide and lift-tilt-slide units Subsequent exchange of 15 mm, 10 mm and 5 mm running rails possible. Complete exterior (weathering) side protected by aluminium profile. Flexible application due to modular system: tread threshold, various drip rails and running rails designed for clip-on assembly. Identical basic profile for timber and PVC patio doors. Anti-moisture foil directly connected to the drip rail. Suitable for the use in barrier free construction to DIN 18025, max. height only 18 mm. Applications G.U-thermostep variants for different applications: timber units with 28 and 10 mm sash clearance timber thicknesses 56 and 68 mm for all leading PVC profile systems and various sash arrangement schemes Further information regarding technical data and application range you will find in our order catalogues: Builder's hardware for timber windows and patio doors Builder's hardware for PVC windows and patio doors
