PS128 Lift‑and‑Slide System

This lifting‑sliding door adopts a slim 72 mm visible sash width with optimized streamlined profile structure. The equal‑width hook‑type interlocking area is equipped with both rubber sealing gaskets and wool pile seals. The centrally thermally‑insulated hooked‑edge profile is precisely fitted with sealing gaskets to realize continuous sealing and thermal insulation. Sealing, thermal insulation and structural reinforcement are compactly integrated within only a 32 mm cross‑section to achieve well‑balanced performance in all three dimensions. Invisible thermal‑break strips create a neat and clean exterior appearance. Two alternative sash styles are provided to maximize viewing transparency, and mullions can be flexibly added to satisfy large‑opening dimension demands.

Three types of bottom tracks are available for different site conditions. Option A: low‑profile bottom track, retains full lifting‑sliding function, enables smooth barrier‑free access for indoor floor‑level scenarios without rain exposure risks. Option B: standard 45 mm high bottom track, suitable for most terrace and entrance‑exit applications with reliable sealing and drainage performance. Option C: recessed high bottom track, seamlessly connected to the ground through pre‑embedded structures for complete barrier‑free passage while delivering premium water‑tightness.

All sliding hardware, functional accessories and outer‑frame bolt connections are fully concealed. The hidden locking system preserves minimalist facade and clean visual effect. This system supports heavy‑duty sashes and features excellent structural rigidity, sealing property and thermal‑insulation performance.
