88 series
Rolansini
88 series non-thermal break casement windows can be seen as a pragmatic choice among doors and windows—spending the budget on the more critical "sealing and safety" performance, while giving up the ultimate pursuit of "heat insulation".
The 88 non-thermal insulation casement window is most suitable for places where heat insulation requirements are not high, but price, sealing and safety are important.
·Balconies, kitchens, and bathrooms in ordinary residential buildings: These spaces are usually not primary living areas and do not have high requirements for temperature regulation, but have strict requirements for ventilation, mosquito prevention, and dust prevention.
·Low-rise residential buildings or rooms not exposed to the west: If the floor is not high, or if the community has good greenery, the impact of summer sun exposure is minimal, and the shortcomings of non-thermal insulation are less noticeable.
·Schools, company dormitories, and rental properties: These places often install insulation in batches, requiring high cost control, as well as durability and basic sealing of doors and windows.

1.Excellent Sealing: Although not thermally broken, it doesn't compromise on fundamental performance aspects such as wind pressure resistance, water tightness, and air tightness. The casement window uses virgin aluminum, multiple sealing strips, and a concealed drainage design, effectively blocking wind, rain, and air infiltration.
2.Customizable Integrated Window Screen: The 88 non-thermally broken series combines the glass window and the stainless steel mesh into one, simultaneously solving the problems of ventilation and mosquito prevention as well as burglar protection, saving space and enhancing security.
3.Affordable Price: Significantly reduced manufacturing costs. While aluminum alloy's rapid heat conduction and poor insulation are its drawbacks, its price is considerably lower than thermally broken aluminum windows, making it an ideal choice for those on a budget.
4.Optimized Structural Design: The product structure is designed to use the same profile for the frame and center post, effectively reducing material waste and facilitating processing and assembly.
