Magnetic screens, also known as magnetic screens and magnetic stripe screens, are simple household screens with high popularity on the market. They rely on soft magnetic strips to adsorb each other to achieve sealing and opening, which is different from two-stage three-push, roll invisible, and diamond mesh. Many owners confuse magnetic screens with other screens when purchasing screens. Structurally, magnetic screens are composed of four core parts: screen mesh, surrounding soft magnetic strips, supporting adhesive magnetic strips, and hemming fabrics. They are simple to install and do not require punching. They are representative products of non-punching screens.

Its working principle is very simple: a fixed magnetic strip with adhesive backing is pasted on one side of the window frame, and a matching suction soft magnetic strip is sewn around the screen net. It is tightly fitted together by the permanent magnet magnetic force. When it is closed, all the surroundings are adsorbed and sealed. When it is necessary to open the window, disassemble and wash it, it can be directly lifted from the corner. Compared with the traditional screw fixed screen and push-pull screen, the biggest feature is the freedom of disassembly and assembly, without destroying the original window and window frame, which is very suitable for renting residents, temporary installation of screens in old houses, and renovation of rental houses.

Magnetic screens focus on the basic functions of anti-mosquito, suitable for casement windows, sliding windows, floor-to-ceiling windows, daylighting windows and other window types, and are also a very popular screen style for online search. However, magnetic screens have clear application boundaries, and not all scenarios are suitable. The following is a step-by-step approach, from the material classification, specifications, advantages and disadvantages, selection, installation, pit avoidance, and maintenance of multiple dimensions, to clarify the professional knowledge points of magnetic screens, so that everyone can choose the right screen window against their own windows.

Classification and performance differences of mainstream mesh materials for magnetic screens

Screen window mesh is the core of magnetic screens. Different mesh materials have a huge gap in permeability, weather resistance, tensile capacity, and service life, which is also the main reason for the difference in merchant quotations. At present, the mainstream is divided into four categories.

First, ordinary polyester polyester mesh (basic model). This is the most common and lowest-priced magnetic screen mesh material. The fiber weaving density is conventional, the mesh is uniform, and the basic anti-mosquito and small flying insects are no problem. The shortcomings are more obvious: long-term sun exposure is easy to age and brittle, easy to hook silk, average light transmittance, and most of the colors are gray. It is suitable for short-term use and temporary use in rental housing. Generally, the service life is 1-2 years.

Second, high definition high-transparency mesh (mainstream upgrade on the market). It is also the same high-transparency mesh material for diamond mesh screens. The mesh is slender, the weaving density is precise, the light transmission and viewing effect are good, the interior will not be significantly darkened, the ventilation resistance is small, and the field of vision is clear. The material has better anti-ultraviolet ability than ordinary polyester, is not easy to yellow, feels smooth, and is not easy to hook silk. It is the preferred mesh material for home ownership, and is also the highest-selling configuration now.

Third, PET nano mosquito repellent net (high-end model). Nano PET material, anti-aging, anti-static, dust is not easy to adhere to the net surface, strong self-cleaning ability, rainwater initialize can take away floating ash, sun exposure resistance, rainwater resistance, not easy to age and become brittle, strong anti-pulling ability, transparent black color, advanced appearance, sufficient budget for self-occupation can be preferred.

Fourth, thicker encryption and anti-pet nets. Specially aimed at families with cats and dogs, the mesh is bold, with strong tensile and tear resistance, and it is not easy for cats to scratch holes. The disadvantage is that the permeability will drop a little, and the ventilation is slightly poor, which is suitable for families with pets.

When purchasing, focus on the mesh density. Household standard mosquito repellent nets are routinely 1816 mesh, which can block mosquitoes, flies, and small moths. Below this mesh, the gap is too large, and small mosquitoes are easy to get in.

Analysis of professional parameters of magnetic strip and hemming accessories for magnetic screens

Many users only look at the gauze, ignoring the magnetic strip and adhesive backing, and whether the magnetic screen can be sealed and how long it can last, the magnetic strip is a key component, and it is also a disaster area for low-cost products to cut corners.

The first is the soft magnetic strip. High-quality magnetic strips use rubber soft magnets, which have high internal magnetic powder content, long-lasting magnetic force, tight adsorption, and are not easy to demagnetize; inferior magnetic strips have low magnetic powder content and weak magnetic force. After a few months, the suction force decreases. When the wind blows, the screen is blown open, and mosquitoes take the opportunity to enter. The conventional width of the magnetic strip is 8mm and 10mm, and the 10mm widened magnetic strip is preferred for household use, which has a larger adsorption area and better sealing effect.

The second is the adhesive. The adhesive is divided into ordinary double-sided tape and strong temperature-resistant adhesive. Ordinary double-sided tape is not resistant to high temperature. After the sun is exposed in summer, the rubber layer melts and flows the glue. It falls off and leaves the glue on the window frame, which is very troublesome to clean up. High-quality magnetic screen windows are matched with automotive-grade temperature-resistant foam adhesive, which is resistant to high temperature and low temperature. It does not flow glue in summer and does not unglue at low temperature in winter. It has less residue after tearing off. It is suitable for plastic steel windows, aluminum alloy windows, and broken bridge aluminum window frames.

Then there is the hemming fabric. The hemming is divided into Oxford cloth, elastic hemming, and PU leather hemming. Oxford cloth is wear-resistant and cost-effective; PU hemming is waterproof, and it is not easy to get moldy in the rain. It is suitable for balconies and outer windows that often rain; low-priced products are hemmed with thin non-woven fabrics, which will crack and go off-line after washing a few times.

There is a professional point: the magnetic strip of the magnetic screen window is divided into a continuous magnetic strip and a segmented magnetic strip. The whole circle of integrated magnetic strips is sealed continuously around, and the probability of mosquito leakage is lower; segmented splicing of magnetic strips, there are gaps in the splicing position, which is easy to enter mosquitoes. Try to give priority to the whole circle of magnetic strips.

Fourth, the core advantages of magnetic screens, suitable for which groups and window types

The reason why the magnetic screen has been selling well for a long time is the unique product advantage, which accurately matches some user requests.

First, the whole process is free from punching holes and hurting the window frame. No electric drills, screws, or welding are required. Just stick the magnetic strip adhesive on the surface of the window frame and install it in a few minutes. Disassembly does not leave a large area of damage. It can be directly removed when the rental expires. It is the first choice for rental groups.

Second, it is very convenient to disassemble and clean. Grab the corner and directly lift the screen window, the whole screen window can be taken off, washed and brushed in the bathroom, and directly adsorbed back after drying. Compared with the fixed welded diamond mesh screen window, the cleaning difficulty is much lower.

Third, the price is close to the people and the customization is flexible. It can be cut and customized according to the size of your own windows. Small windows, special-shaped small windows, and lighting windows can all be done. The cost is much lower than that of diamond mesh screens and system screens. The overall cost of multi-window transformation is controllable.

Fourth, the opening and closing are quiet and there is no noise. Relying on magnetic adsorption, there is no pulley or track, and there will be no abnormal sound of push-pull cards and pulleys. It is also very friendly for the elderly and children to use.

Fifth, the style is lightweight and will not block the line of sight. The style of high-transparency mesh has a transparent field of vision and will not suppress lighting like thick diamond mesh. It is suitable for apartment types with weak indoor lighting itself.

Suitable window type: inner casement window, outer casement window, left and right sliding aluminum alloy window, plastic steel window, floor-to-ceiling window, bathroom small window. Suitable for the crowd: renters, short-term residence, limited budget, owners who need to dismantle and wash the screen windows frequently, and do not want to punch holes in the window frame.

Fifth, the shortcomings and limitations of magnetic screen windows, which scenarios are not recommended

Magnetic screens have outstanding advantages, but they have clear shortcomings. If the scene is selected incorrectly, the later experience will be very poor, and many bad reviews are caused by the wrong selection.

First, the wind resistance is weak. It relies on magnetic bonding, and in strong winds and strong convection weather, styles with insufficient suction are easy to be opened by the wind, so high-rise windward and open facade windows are not recommended to use magnetic screens alone. Diamond mesh screens are preferred in windy areas.

Second, the protection is insufficient, there is no anti-fall and anti-climbing ability. Magnetic gauze is only a fabric mesh surface and cannot bear the weight of the human body. There are windows for young children at home, so it cannot be used as a protective fence. It only has anti-mosquito function and no security effect. This is a very important safety knowledge point.

Third, the service life is limited. Even high-quality PET mesh models, exposed to outdoor sunlight all year round, generally age in 3-5 years and the magnetic strip magnetic force attenuates; low-priced models have insufficient suction and screen damage in about 1 year, which is obviously different from the 8-15 year service life of diamond mesh screens.

Fourth, the sealing effect is greatly affected by the surface of the window frame. If the surface of the window frame is peeling, paint peeling, uneven, uneven adhesive stickers, and gaps in the magnetic strip fit, mosquitoes will drill through the gaps; curved and irregularly curved window frames, it is difficult to achieve tight magnetic sealing.

Fifth, it is easy to be scratched by pets. Cats and dogs scratching can easily break the gauze. If pet families must use it, they must choose a thickened anti-scratch special net.

Simple summary: Magnetic screen positioning is an economical anti-mosquito screen, focusing on convenience, not security screens, and its strength and wind resistance cannot be overestimated.

Standardized measurement and installation of magnetic screens

Measuring size, pasting magnetic strip, screen window adsorption installation steps

If the magnetic screen window wants to be tightly sealed and not leak mosquitoes, measurement and installation are the key. Many screens purchased online are not easy to use. The root cause is that the size measurement is wrong and the magnetic stripe is not standardized.

The first step is to accurately measure the net size of the window frame. Measure the length and width of the inner side of the window frame, noting that it is not the size of the window glass. When measuring, measure the upper, middle and lower widths and the left and right heights respectively, and take the minimum value to avoid the deformation of the window frame and the inability to install it; when customizing, generally reserve 2-3mm margin to ensure magnetic bonding.

The second step is to clean the base surface of the window frame. Before pasting the magnetic strip, you must wipe all the dust, oil and old glue stains on the surface of the window frame, wipe it with alcohol and dry it. The base surface is clean and adhesive-backed to stick firmly. The oil-stained surface will fall off in a short period of time.

The third step is to paste the fixed magnetic strip. Tear off the adhesive-backed protective film, align the magnetic strip in a whole circle along the inner edge of the window frame, press hard after sticking, and let it stand for 24 hours to let the adhesive fully solidify. Do not use the screen immediately.

The fourth step is to align the adsorption screen window. Align the screen window of the sewn magnetic stripe with the magnetic stripe of the window frame, slowly fit it, check that all the surroundings are sucked tightly, and there are no gaps in the four corners and four sides; the corner warping edge indicates the size or the position deviation of the magnetic stripe, and adjust it in time.

The fifth step is trimming and debugging. The excess corners can be simply cut, the window can be opened and closed to test whether the opening and adsorption are smooth, and the gap can be checked for air leakage and light transmission.

Installation taboos: wet and seeping window frames and walls with falling off wall skin are not suitable for pasting adhesive-backed magnetic strips, which are easy to fall off.

Seven, magnetic screen purchase points, avoid common routines in the industry

The price range of magnetic screen windows on the market is very large, from tens to hundreds of yuan for a set. Many merchants pay low prices for drainage and switch configurations. Here are the key points for sorting out and purchasing.

First, distinguish between mesh and material, don't just look at the "high transparency" title. Many merchants also mark ordinary polyester mesh with high transparency. Confirm the material before placing an order, give priority to PET or thickened high transparency polyester mesh, and confirm the mesh number of ≥18 mesh.

Second, confirm that the magnetic stripe is an integrated magnetic stripe, refuse to splice the magnetic stripe in sections, the contract or remarks state that the width is 10mm soft magnetic, and refuse the thin and narrow magnetic stripe.

Third, confirm the type of adhesive backing, ask whether it is temperature-resistant, and avoid the corrosion of the paint surface of the window frame by the flow of glue in summer. Special attention should be paid to the problem of flow of glue in broken bridge aluminum and high-end aluminum frames, which is very troublesome to clean.

Fourth, according to the floor selection: low-floor windless, inner windows can be normally selected for magnetic screens; high-rise, windward windows, priority with diamond mesh, or choose magnetic attraction only as an auxiliary inner window screen.

Fifth, distinguish between finished products and customization: standard small windows can buy finished products, special-shaped and large floor-to-ceiling windows must be customized separately, and the finished product has large size errors and poor sealing.

Sixth, ask the after-sales service clearly: whether the gauze mesh is broken and supports separate screen change, and whether the magnetic strip can be reissued separately due to the suction attenuation of the magnetic strip. Many low-priced models can only be replaced in a complete set if they are broken.

Eight, the daily cleaning, maintenance and replacement cycle of magnetic screens

Good maintenance can prolong the service life of magnetic screens and maintain the magnetic force and sealing effect.

Cleaning method: directly remove the whole piece, add neutral detergent with water, brush the net surface dust with a soft brush, mosquito corpses, do not use strong alkali or strong acid cleaners, it will accelerate the aging of the mesh material; after washing, dry in a cool place, prohibit sun exposure and drying, it is easy to accelerate the brittleness of the gauze.

Magnetic stripe maintenance: Regularly wipe the surface dust and fluff of the magnetic stripe with a damp rag. After a large amount of hair dust is attached to the surface of the magnetic stripe, the magnetic force will decrease and the seal will not be tight. Do not scratch the surface of the magnetic stripe with sharp hard objects. Damaging the magnetic powder layer will permanently demagnetize.

Storage: When not in use in different seasons, wash and dry, roll it up flat and store it, do not fold and press it heavily to avoid the magnetic strip breaking.

Replacement reference cycle: 1-2 years for ordinary polyester mesh; 2-3 years for high-permeability polyester mesh; 3-5 years for PET nano mesh; the magnetic strip suction is obviously weakened, it opens when the wind blows, and there are many holes in the gauze mesh. It is recommended to replace.

In general, the magnetic screen is a lightweight, non-punching, low-cost, disassembly and assembly of flexible anti-mosquito screen products, relying on the principle of soft magnetic suction to achieve closed sealing, mainstream mesh materials include ordinary polyester, high definition high penetration net, PET nano net, anti-grab pet net, matching magnetic stripe, temperature adhesive, hemming fabric directly determines product quality.

Its biggest advantage is that it does not need to punch holes to damage the window frame, is easy to disassemble and wash, and is affordable. It is suitable for renting, short-term living, inner casement windows, and basic mosquito protection for lighting windows. However, it has limited wind resistance, no security protection function, and short service life. High-rise windward windows and scenes where young children need protection at home are not suitable for use alone.

When purchasing a magnetic screen window, you can't just compare the price, but focus on confirming the mesh number, whether the magnetic strip is integrated, and the temperature resistance of the adhesive backing; clean the window frame during installation to give the adhesive backing enough curing time; clean the magnetic strip and screen regularly in the later stage to reduce the suction attenuation caused by dust. If you pursue long-term durability, high-level security and anti-fall, priority should be given to diamond screen windows; you only need simple anti-mosquito, do not want to punch holes, and clean frequently. Magnetic screen windows are cost-effective choices.
