Features & Benefits
Liberty 21 Door & Window systems are designed for the secure installation of hinges, locks, and handles, offering a high level of protection against intrusion. ENCRAFT systems are naturally flame-retardant, reducing the fire load in case of a building fire, ensuring greater safety and peace of mind.
Engineered with precision, the Liberty21 product range, when installed following standard guidelines such as BSB2134, provides superior protection against the elements. Unlike other materials, uPVC does not rot, split, warp, or corrode, making it a durable and reliable solution for all weather conditions.
Liberty 21 uPVC Door and Window systems feature a multi-chambered profile design with double seal technology, ensuring outstanding sound insulation. When paired with appropriate glazing, these systems can reduce noise infiltration by up to 54 dB, offering a quieter, more comfortable environment.
Liberty 21 uPVC doors and windows are built to withstand wind pressures exceeding 3000 Pascal, equivalent to wind speeds of 250 km/h. This makes them an excellent choice for modern high-rise buildings, providing flexibility and resilience during storms.
Liberty 21 doors and windows are designed to offer robust protection against high UV exposure. From material selection to advanced extrusion processes, every step ensures the highest quality profiles that can resist UV radiation, a common issue in the Indian subcontinent.
With superior thermal properties, uPVC is an excellent choice for fenestration solutions. Liberty21’s systems provide exceptional thermal insulation, with the TwinSash capable of achieving a U-value as low as 0.8 W/m²K when paired with double-glazed units. This makes TwinSash a highly energy-efficient, comfortable, and cost-effective solution for various markets.
uPVC is difficult to ignite, and even if it does catch fire, it will self-extinguish once the flame source is removed. uPVC does not support combustion and will not spread fire on its own, boasting one of the lowest surface spread of flame ratings among building materials.
