Excellent temperature preservation performance: As well as a heat conductivity factor, PVC has a temperature insulation effect. Its insulation qualities are 1250 times better than aluminum material.
Good sound insulation performance: Its structure is designed very well, with tight joints. The test result indicates that its sound insulation is <20db and complies with DIDN4109.
Anti-aging: During the manufacturing process denaturalizing agent is applied. This is the agent for preventing UV rays absorption which is added in the raw materials. The product does not discolor, age or become brittle even when it is exposed to direct sunlight, rainstorm, drying or humidity between -30°C and 82°C.
Good combustion-retarding performance: Conch profile is made of quality combustion-retarding material. It does not ignite itself or support combustion and can extinguish the fire by itself.
Resist impacts: Special impact-resisting design is applied. The section of material can bear a cold impact test of 1kg hammer dropping freely from one meter height at -10°C
Good waterproof performance: Its water absorption is <0.1%. The doors and windows are designed to have rainproof plates and water drain slots, and can completely isolate the rainwater outside. Its waterproof performance complies with DIDN18055.
Good anti-theft: Our door and windows are provided with high-quality hardware and internal beading that makes the design much more difficult for intruders to gain any unlawful access.
Easy to maintain: Conch profile sections do not corrode and will not discolor. They are not affected by ash, cement or any binding agents. They require almost no maintenance.
Good air tightness.: All the profile joints are welded and any gaps in the system are sealed with ternary sealing strips. Each unit length of profile must vent below 4m³mmhm. This adds to the efficiency and energy saving qualities of the product.
Pest Resistant: Wood boring insects such as termites can cause havoc with timber frames reducing them to powder in a short space of time and undermining the door and window structure as a whole. PVC windows and doors are impervious to such attacks. No insects or pests will eat through uPVC.
