Introduction

FSC's high quality windows are combined with high strength Aluminum profile and high insulation Polystyrene profile have superior airtightness, insulation, sound proofing property, durability, interiors and keep ahead in economic feasibility. (Aluminum Window Frames

• The thermal conductance of aluminum is high.
• Condensation or even frost forms inside the windows. PVC Window Frames
• Limited colors available.
• Too much heat can rupture the frames.
• Not easy to replace, and can be costly.
• A fire would cause the vinyl to give off dangerous toxic fumes.)

(1) Environmental Friendly Polystyrene-3R

• Reduce- Energy- efficient product which can reduce heating and cooling costs by high insulation performance
• Reuse- Reuseable product which can replace only polystyrene part when it needs renovation or repairing
• Recycle- Recycleable more than 90% so that can minimize wastes

(2) Thermal insulation of Polystyrene

Material	Thermal conductivity	Comparison priority	Note
Polystyrene	0.055W/m.k	1	Standards
Azon	0.121W/m.k	2	2.2times
Polyamide	0.30W/m.k	3	5.5times
Aluminum	237W/m.k	4	4300times

(3) Other Benefits

• The Appearance of Polystyrene and UV transcription coating
  - Natural wood pattern of UV transcription coating brings a similar texture like wood but its price is low. The outside aluminum is applicable by various colors and the warm natural wood feeling of inside insulating material of Polystyrene raises the effect of interior, which enables to satisfy the needs of consumers.
• High resistance to water and vapour
  - Unlike the natural wood with its weak resistance to humidity and easy transformation, Polystyrene is resistant to water and not fall into decay enough to maintain its performance continuously even if it exposed to water.
• Soundproof
  - Soundproof Criterion Factor
  - Polystyrene: 50dB (Aluminum: 35dB, PVC : 40dB)

Schoolyard 85dB

• Refractoriness
  - Polystyrene has ability to self extinguish. Moreover unlike PVC, the products do not produce toxic gas in case of fire.

Casement, Awning/Hopper Window

Casement Windows are fully open to vertical and horizontal position and provide excellent ventilation and lighting effects. Also, the casement of FSC composite window, which fully close and airtight by pressing sash against the frame, provides excellent sealing effect. It also helps prevent air entry and leakage.
Awning Window, which has a fixed upper part, opens the lower part of the window toward outside. It has an excellent ventilation effect while protect entering of rainwater and foreign maters, and when the window closed, it shows excellent watertight and airtight performance.
Hopper Window, which has a fixed lower part, opens the upper part of the window toward inside. It has an excellent ventilation effect when fully opened, and fully airtight when closed.
