SOUND PROOFING WALLS
Soundproof Tunnel(PRISM PC-type)
Optimum Soundproof Tunnel designed
to inhibit reflected light
This is a soundproof tunnel made by the optimal soundproof tunnel roof material system construction method which is designed for great stiffness, with perfect waterproofing ability, and the suppression of reflected light by using a highly stiff frame (PO SMAC), 4-stage waterproofing and reflected lightreducing roof materials (PRISM PC ).
Soundproof Tunnel that completely blocks reflected light
- Excellent frame stiffness (POSMAC)
- Additional rust-proofing not required (ultra-precision alloy steel)
- Complete water leakage protection
(4-stage waterproofing = sealing + gasket + hydrophilic waterstop + finishing material) - Complete prevention of damages caused by reflected light (10G.U-PRISM PC)
- Inhibition of glare phenomenon inside a tunnel
(15% or more difference in total light transmittance of upper and lower surfaces) - Tunnel interior illumination enhancement (total light transmittance of 90% or more)
- Possible to be applied to H-beams, pipes, and structures of any shape

Difference between high-stiffness transparent panel and general PC
| Category | PRISM PC | General PC |
|---|---|---|
| Characteristics | Alloy steel with stiffness greater than or equal to that of SS400 |
Made of aluminum, which is relatively less stiff |
| Reflective light | Diffracts and reflects the light coming from a light source to minimize the damage done by the reflected light |
Damage done by reflected light is generated as the light from the source is reflected |
| Glossiness | 10 G.U or less | 100 G.U or more |
| Total light transmittance |
Upper surface: 94.2% Lower surface: 70.4% No glare phenomenon because the difference between the upper and lower surfaces is 23.8% |
Upper surface: Greater than 85% Lower surface: Greater than 85% Glare phenomenon occurs as there is no difference between the upper and lower surfaces |
Application of Soundproof Tunnel (PRISM PC type)
-
Pokposa Intersection in Haeundae, Busan
-
