Hollow lightweight panel(HLC)

- Structural Change of Multi-family Housing (Strength Wall → Column Type)

Before (Wall-type)	After (Column-type)
→
ㆍReduced durability due to aging of internal piping and noise transmission to internal walls (26 years) ㆍThe weighting of general concrete causes foundation part and load transferring subsidiary material bigger.	ㆍWeight capable of human labor (70kg/Span) ㆍFull-flammable (weapon material) fire resistance for 2 hours or longer ㆍSecuring the function of double wall with hollow type (insulation and noise)

- Product Overview

Transition from existing sandwich panels to modularized hollow ultra-light concrete panels.

Existing: Sandwich Panel and Others	Conversion: HLC Ultra Lightweight Foamed Concrete Panel
① Sandwich Panel is flammable, thus fire hazard ② Cement extruded panels (Limitability of weight: 140kg/span) ③ ALC block has more labor and construction complexity than panels ④ gypsum boards are on-site construction, increasing construction period and labor.	① Double wall function with hollow type (reduced by 30.5% of total volume) ② Increase in strength of industrial products in bubble concrete ③ Ultra lightweight (70kg/Span) with human resources ④ Completely non-combustible material consisting of inorganic material (resistance of more than 2 hours)
