A large number of old residential areas, old houses, and old-fashioned villas in Shanghai are facing the problem of aging doors and windows: cold air leakage in winter, lack of insulation in summer, loud noise on the street, easy water leakage on rainy days, and hardware rusting and difficult to open... Changing windows in old houses has become the key to improving living happiness. In the custom door and window market in Shanghai, Lan-system System doors and windows have become a popular choice for old house window replacement due to their mature products, professional installation, and high cost-effectiveness.
The biggest pain points of replacing windows in old houses are poor adaptability, high construction damage, and difficult maintenance in the later stage. Many small brand doors and windows have inaccurate dimensions and rough installation, resulting in air and water leakage even after replacement; Outsourced construction teams lack standardization, which can easily damage walls, underfloor heating, and decoration; Some merchants even attract customers at low prices, resulting in continuous price increases in the later stages, causing unbearable suffering for homeowners. Lan-system System's doors and windows solve these problems from the source, providing a worry free, reassuring, and secure window replacement solution for old homeowners in Shanghai.
Based on the characteristics of old houses in Shanghai, Lan-system has launched the 70, 75, and 80 series of cost-effective system windows, which are suitable for the climate in East China, meet performance standards, and are price friendly. The profile is made of 6060 T66 high-precision aluminum alloy, with a wall thickness of 1.8mm, high strength, and no deformation; Hollow tempered glass or three glass two chamber filled with argon gas, with significant insulation and sound insulation effects; The insulation strip is made of PA66GF25 material, with insulation performance far exceeding that of ordinary PVC strips; Combined with EPDM sealing strips, multiple seals are achieved to effectively prevent air and water leakage.
For the most concerned issue of sound insulation for old homeowners, the Lan-system system window sound insulation can reach 35-45dB, effectively filtering out road noise, neighbor noise, and hallway noise, bringing the bedroom back to quietness. After upgrading the insulation performance, the indoor temperature is more stable in winter, the energy consumption of air conditioning is reduced in summer, and long-term use is more cost-effective.
