Shanghai invisible screen customization | Suitable for Shanghai Meiyu typhoon climate, professional guide for material, selection, installation, and pit avoidance

First, the demand characteristics of invisible screens in Shanghai: the local climate determines the configuration standards of screens

Schematic diagram of Shanghai climate characteristics and screen pain points

Many Shanghai owners will choose invisible screens when decorating or changing windows in old houses, but Shanghai is different from other cities. It belongs to a subtropical monsoon climate, with high humidity in the plum rain season, frequent typhoons in summer and autumn, salt mist in the air in the riverside area, long mosquito cycles, and a lot of urban catkins and dust. This is also the core starting point for purchasing invisible screens in Shanghai. From May to October every year is the period of high incidence of mosquitoes in Shanghai, and Aedes albopictus (flower-footed mosquitoes) are active frequently. Ordinary screens are prone to rust, loose mesh, strong wind, and moldy cards. Many owners fail after one or two years of installation.

Invisible screen window, also known as roller shutter invisible screen window, relies on the spring structure of the reel. When not in use, the screen screen is automatically retracted into the interior of the top aluminum alloy reel, which does not block the view of the window, does not affect the opening of the doors and windows, and has a simple appearance. It is very suitable for Shanghai commercial housing, old and small, large flat floors, river view rooms, and villas. Compared with fixed diamond mesh screens, the biggest advantage of invisible screens is that they can be stored and do not block lighting. They are suitable for external open windows, casement windows, and sliding windows.

In this paper, step by step, combined with the local environment in Shanghai, from product classification, gauze material, profile accessories, measurement and installation specifications, different apartment type selection, quotation and pit avoidance, maintenance and maintenance, to explain the professional knowledge of Shanghai invisible screen windows, covering Pudong, Xuhui, Minhang, Baoshan, Jiading, Songjiang, Qingpu and other regions, hardcover new houses, old residential renovation, villa doors and windows matching needs.

Second, the mainstream style classification of Shanghai invisible screens, understand the differences in different structures

Comparison chart of rolling blind invisible screen window and folding invisible screen window

The mainstream invisible screens in the Shanghai market are divided into two categories: upper and lower roller shutter invisible screens and left and right folding invisible screens. Among them, the roller shutter model is the style with the largest amount of home decoration in Shanghai. There are also a small number of magnetic invisible screens as a supplement. Different structures are adapted to different window types.

The first type is the invisible screen window of the upper and lower roller blinds (mainstream model). The vertical reel structure, the screen net is retracted up and down, and it is matched with left and right guide rails. It is suitable for most casement windows and outer windows, and is also the most common style in Shanghai communities. It is divided into spring self-elastic models and damping buffer models. The high-end models are equipped with windproof beads and windproof ropes, which are specially designed to deal with the windy weather of Shanghai typhoons to prevent the screen net from being blown off the track and bulging off by the wind. The advantages are simple storage and good sealing; the disadvantages are that large-width floor-to-ceiling windows are not suitable. If they are too wide

The second type is to fold the invisible screen window left and right (organ type). Horizontal folding storage, suitable for wide floor-to-ceiling windows, balcony sliding doors, large holes, and large flat layers with river view. The screen mesh is folded in sections, the track is thin, and the ventilation and vision are good, but the windproof performance is weaker than that of the roller shutter model. It is not recommended for high-rise use in typhoon days.

The third type is the magnetic invisible screen window (simple model). The frame is matched with a magnetic strip, which is easy to disassemble and assemble, and the price is cheap. It is mostly used for temporary use and rental housing. It has poor sealing and wind resistance, and is not suitable for long-term household and high-rise households.

Professional selection summary: ordinary household casement windows and external windows, priority is given to damping roller shutter invisible screen windows; large floor-to-ceiling windows, balcony doors, low-rise windless environment can choose folding models; high-rise, riverside, close to the river, priority is given to roller shutter invisible screen windows with windproof system.

Detailed explanation of gauze material, how to choose gauze in Shanghai's humid environment

PET high-permeability mesh, 304 flexible steel mesh, glass fiber mesh material details comparison chart

Screen mesh is the core of invisible screen windows. Shanghai has high humidity and salt spray in some riverside areas. If the material is wrong, it is easy to get moldy, rust, and brittle. Common gauze mesh on the market is divided into PET high-permeability mesh, 304 flexible steel mesh, glass fiber mesh, and ordinary polyester mesh, with obvious performance gaps.

1. PET high-transparency mesh (popular in Shanghai home improvement): polymer polyester fiber material, mainly 20 mesh and 24 mesh, high light transmittance, transparent field of vision, does not block lighting, anti-ultraviolet, not easy to mold, light weight, smooth spring pulling, suitable for ordinary residential and hardcover rooms in urban areas. The disadvantage is that the anti-scratch performance is average, and families with cats and pets at home should use it with caution.

2. 304 flexible steel mesh (high-end durable model): stainless steel filament weaving, 9 wires and 24 mesh are the mainstream specifications, tensile resistance, anti-cat scratch, tear resistance, moisture resistance, preferred in coastal areas such as riverside, Linjiang, Chongming, etc. Pay attention to distinguish 201 stainless steel. 201 will rust in 1-2 years in Shanghai's humid salt spray environment. It is easy for merchants to use 201 as 304.

3. Glass fiber mesh: The price is low, but the weather resistance is poor. It is easy to turn yellow and brittle after exposure to the sun. It is easy to get damp and moldy in the rainy season. Shanghai does not recommend long-term household use.

4. Ordinary polyester mesh: low-cost screens come standard, easy to accumulate dust, aging quickly, and have a short service life, making it only suitable for temporary use.

Popular science of mesh number: Shanghai mosquito control is preferred to 20 mesh and above, and 24 mesh can block smaller flying insects; the higher the mesh number, the better the insect control effect, and the ventilation will decrease slightly. Don't blindly pursue high mesh number.

Fourth, aluminum alloy profiles and core accessories determine the service life of Shanghai invisible screens

Close-up picture of invisible screen window reel, track, spring, windproof bead accessories

The failure rate of invisible screen windows in Shanghai is mostly due to thin profiles, inferior springs, and lack of windproof accessories. Qualified invisible screen window profiles are made of 6063 native aluminum alloy, with a conventional wall thickness of 0.8-1.0mm and a high-end model of 1.2mm. The surface is sprayed with fluorocarbon or electrostatic powder, which is resistant to moisture and rain corrosion, and is not easy to peel and fade. If it is recycled aluminum and a thin material with a wall thickness of less than 0.6mm, the track is easily deformed after the moisture in the plum rain season, and the yarn network interface card.

The first core accessory is the spring system: the invisible screen window relies on the spring to rewind, and the inferior spring is prone to fatigue and failure, and the screen screen cannot be retracted and the rebound is weak. Shanghai has a large temperature difference all year round, and stainless steel constant force springs are preferred, which have a longer service life and are matched with damping buffers. It will not hit the reel when closed.

The second is the windproof structure, which is a must for high-rise in Shanghai: ordinary invisible screens do not have windproof beads and windproof ropes, and the gauze is derailed when the wind blows, which is the most complained problem by Shanghai owners. High-rise and riverside apartment types must be equipped with windproof beads and windproof rope structures to firmly lock the gauze, and the typhoon weather is not easy to derail the drum net.

The third is the guide groove and brush strip: high-density silicified brush, closing the gap, dustproof and mosquito-proof, while reducing the friction noise of the gauze mesh; ordinary brushes are easy to lose hair, harden, and age rapidly in a humid environment.

V. Shanghai Invisible Screen Standard Measurement and Installation Specifications to Reduce Water Seepage and Damage to Original Windows

Invisible screen door measurement, installation construction map

Invisible screens are customized products, with three products and seven installations. The windows of old houses in Shanghai have complex structures, including old-fashioned steel windows, broken bridge aluminum windows, and plastic steel windows. The widths of the window frames vary, and the installation is slightly improper, which will damage the original external wall seal and seep water from the windows in rainy seasons.

The first step is door-to-door survey: the master measures the inner diameter of the window frame on site, distinguishes between interior, exterior, and frame installation, and judges the opening direction of the window. The outer window should be reserved for a safe distance to avoid bumping between the screen window and the window sash. The upper layer should also confirm the location of the outer wall glue, so as not to damage the original waterproof glue layer.

The second step of installation: divided into inline installation and outer frame installation. The inline is beautiful, suitable for new houses with sufficient window frame width; the frame is suitable for old windows and old-fashioned windows with narrow window frames. High-rise installation prohibits random punching to damage the waterproof layer of the outer wall. The punching position must be sealed with weathering glue later.

The third step is fixing and sealing: the screws are fixed firmly, and the gaps are sealed with neutral weathering glue. Acid glue cannot be used. Acid glue will corrode aluminum alloy profiles, and it is easy to turn black and moldy in a rainy environment.

The fourth step of debugging: After the installation is completed, repeatedly test the rebound, damping, and windproof structures, check the alignment of the left and right tracks, the gauze screen does not run off or get stuck, and the brush fits tightly.

Important reminder for local installation in Shanghai: try to avoid rainy construction in the rainy season, and the rubber layer needs to be dried and cured; for river view rooms and high floors, check whether all the windproof components are installed after installation.

Six, Shanghai different apartment types, floor invisible screen matching scheme, directly compare the selection

Shanghai different apartment screen window scheme reference map

Combining with the urban characteristics of Shanghai, we organize the floor matching scheme for the owners in different scenarios, and adapt them to different regions, floors and apartment types.

Option 1: Urban mid-rise, not riverside, ordinary commercial housing, no pets at home. Recommended PET high-transparency roller shutter invisible screen window, 20 mesh, damping buffer, standard silica brush, cost-effective, good lighting, suitable for Xuhui, Minhang, Jing'an and other urban residences.

Option 2: High-rise, riverside, riverside, Chongming riverside area. Priority is given to 304 flexible steel mesh roller shutter invisible screen window, with windproof beads and windproof ropes, constant force springs, fluorocarbon sprayed aluminum to resist salt spray and strong wind and prevent rust drum net.

Option 3: If there are cats and pets at home, it is easy to scratch the gauze. 304 soft steel mesh is directly used, which is resistant to scratching and tearing, and is not easy to break.

Option 4: Old broken and small, old-fashioned external windows, narrow window frames. The invisible screen window with narrow frame attached frame is selected, which will not affect the opening of the original window and avoid punching holes and damaging the old wall.

Option 5: Large flat floor-to-ceiling windows, balcony sliding doors, and low-level windless environment. Folding invisible screen windows left and right, with large holes and beautiful storage.

It is not recommended to use simple magnetic screens in high-rise and riverside areas, and ordinary roller shutters without wind protection, which poses a high risk in the typhoon season.

Seven, Shanghai invisible screen market quotation composition, understand the price difference

Invisible screen quotation reference diagram

The price of invisible screen windows in Shanghai is greatly affected by profiles, gauze nets, windproof accessories, sizes, and door-to-door measurement and installation. The market range is clear, which is convenient for owners to compare prices.

PET high-transparency mesh basic roller shutter invisible screen window: 120-220 yuan/fan;

304 flexible steel mesh with windproof roller shutter invisible screen window: 220-380 yuan/fan;

Folding organ invisible screen: 260 - 450 yuan/fan;

Simple magnetic screen window: 60 - 120 yuan/fan.

Common additions: extra-large size widening and price increase, frame customization, aerial work fee, old screen removal fee, and after-sales fee for replacing the spring screen separately. Many low-priced drainage packages do not include windproof components and damping. If you want to upgrade later, you will have to add extra money. When comparing the price, you must confirm the configuration list and write it into the contract.

8. Shanghai invisible screen window purchase avoidance guide to avoid local high-frequency routines

Schematic diagram of screen window purchase pit avoidance comparison

In Shanghai, there are several industry routines that are very common in the local area to avoid in advance and reduce after-sales troubles.

Pit 1: Use 201 stainless steel to pretend to be 304 soft steel mesh, which is difficult for the owner to distinguish with the naked eye. The humid riverside environment will rust for more than a year; you can bring your own stainless steel testing solution for verification.

Pit 2: profile wall thickness virtual standard, 0.6 thin material pretending to be 1.0 thick aluminum, Meiyu moisture deformation, track bending, yarn network interface card.

Pit 3: The low-priced package does not contain windproof accessories, and the high-level does not add windproof beads. The typhoon sky gauze net is derailed, and the merchant will shirk responsibility in the later stage.

Pit 4: The use of inferior springs, the rebound fails in half a year, the gauze cannot be collected, and the local master cannot be found after sales.

Pit 5: Install and use acidic glass glue, which will turn black and moldy for a period of time, corrode the window frame, and seep water around the window.

Pit 6: Foreign merchants are only responsible for delivery. There is no after-sales service in Shanghai. If the spring and gauze are broken, they cannot be repaired on the door.

Pit avoidance core: priority is given to merchants with local factories in Shanghai, door-to-door survey, and local after-sales service. The contract states the wall thickness of the profile, the material of the gauze, whether it has windproof damping, and the quality assurance period.

Nine, Shanghai invisible screen Meiyu, typhoon season maintenance methods

Schematic diagram of daily cleaning and maintenance of screen windows

Shanghai Meiyu humid, summer and autumn typhoon, correct maintenance can prolong the invisible screen life, reduce mildew, card failure.

1. Before the coming of Meiyu, check the brush strips and track gaps, clean up the dust and leaves, and prevent water accumulation and mildew;

2. Use a soft brush and water to clean the gauze, do not use strong alkali detergents to corrode the gauze coating;

3. Before the typhoon comes, completely put the gauze into the reel to reduce the continuous pulling of the gauze by the strong wind and reduce the probability of damage to the drum net;

4. If you find that the rebound is weak and the gauze is deviated, do not force it, and contact the master to adjust the spring tension;

5. When not in use for a long time, keep the gauze screen stored inside the reel to reduce direct sunlight aging;

6. Regularly check the sealant, find that the rubber strip is cracked and blackened, and replenish the neutral weathering glue in time.

Full text summary

Shanghai invisible screen window purchase points mind map

Overall, Shanghai invisible screens cannot be directly copied from other common configurations. High humidity, typhoon winds, riverside salt fog, and long mosquito cycles are the core local constraints, which are also the biggest differences between them and invisible screens in northern cities.

Roller-type invisible screen windows are the mainstream of Shanghai home improvement. If you want good lighting and a moderate budget, choose PET high-transparency mesh; riverside, high-rise, and pet-preferred 304 flexible steel mesh, you must confirm that it is authentic 304 material; high-rise apartment windproof beads and windproof ropes belong to rigid demand configurations and cannot be saved. Folding screens are suitable for large openings and low-rise floors, and high-rise buildings are carefully selected.

At the same time, the invisible screen window is a customized product, and the measurement and installation process directly affect the waterproofing and use experience. Special attention should be paid to the renovation of the old house not to damage the waterproofing of the original window. When purchasing, don't just compare the unit price, focus on checking the type of profiles, springs, windproof structures, and glues. Priority should be given to local service providers in Shanghai to ensure after-sales of door-to-door maintenance, screen replacement, and spring replacement in the later stage.

A set of invisible screens suitable for Shanghai's climate, taking into account invisible storage, transparent lighting, and efficient mosquito prevention. When opening the window for ventilation, it can isolate mosquitoes and insects without damaging the overall appearance of the window. It is a very popular accessory product for the renovation of new and old houses in Shanghai.
