Side curtains on cars: protection from the sun, prying eyes and interior overheating

Side curtains for a car are not just an accessory for tuning, but a practical solution to several problems at once: from protecting the interior from fading to ensuring privacy. In hot weather, they reduce the temperature inside the car by 5–7°C, in winter they protect from snow and icing of glass, and in city traffic - from prying eyes. However, not all curtains are equally useful: some are attached to suction cups and fly off at higher speeds 80 km/h, others require drilling of the body, and still others are generally prohibited by traffic rules in some regions.

In this article we will look at all types of side curtains — from magnetic to electric, we’ll tell you how to choose material (from budget polyester to premium Carbon Fiber), and we will give step-by-step instructions for installation without damaging the paintwork. We will pay special attention legal aspects: where their use is permitted, and where they face a fine of up to 5000 ₽. At the end there is a checklist for purchase and answers to frequently asked questions, including “is it possible to drive with curtains on the highway” and “how to wash them.”

Why do you need side curtains on a car: 5 real reasons to install them

Many drivers consider curtains to be purely a “decorative” element, but in practice they solve specific problems:

• 🔥 Interior overheat protection. According to AAA (American Automobile Association), at air temperature +30°C inside a closed machine it rises to +50–60°C in 30 minutes. Curtains reduce this figure by 15–20% due to the reflection of UV rays.
• 👀 Privacy. In traffic jams or in a parking lot, not everyone wants passers-by to see the contents of the cabin (especially true for owners of SUVs and station wagons).
• 🚗 Safety of things. Robbers often target cars where valuables can be seen in the back seat. Curtains make “reconnaissance” more difficult.
• ☀️ Protection against plastic fading. UV rays destroy the material of the dashboard and seats. High-quality curtains block up to 99% UV radiation.
• ❄️ Winter protection. In cold weather, curtains reduce icing on the windows and reduce the time it takes to warm up the interior.

It is important to understand: not all curtains are equally effective. For example, fabric models with low density pass up to 30% light, and metallized may create glare that distracts the driver. More details about the materials are in the next section.

Types of side curtains: comparison of materials and designs

The market offers more 15 types of curtains, differing in material, method of fastening and level of light transmission. We have selected 5 most popular options with their pros and cons:

Curtain type	Material	Light transmission	Pros	Cons
Magnetic	Polyester + magnets	5–15%	Quick installation, no drilling required, suitable for rental cars	Can fly off at high speed, not suitable for cars with thick paintwork
On suction cups	PVC or acrylic	0–10%	Cheap, easy to remove/install	Suction cups lose vacuum after 1–2 years and leave marks on glass
Rolled	Aluminum + fabric	0–5%	Compact, height adjustable, long service life	Difficult installation, high price (from 8000 ₽)
Electrical	Fiberglass + motor	0–20% (adjustable)	Remote control, premium appearance	Requires connection to the on-board network, price from 25 000 ₽
Stationary (mortise)	Aluminum/carbon	0%	Maximum protection, do not move when moving	Irreversible changes to the body, difficulty in dismantling

For most drivers, the optimal choice is magnetic or roller blinds. The first ones are suitable for those who often remove/install them (for example, for washing), the second ones are suitable for those who value reliability and are willing to spend time on installation. Electric models should be considered only for premium cars (for example, Mercedes S-Class or BMW 7 Series), where they fit harmoniously into the interior.

⚠️ Attention: Curtains with metallized coating (type "mirror") can create glare that distracts drivers in the oncoming lane. In some EU countries they are prohibited - check local traffic regulations.

How to choose curtains for your car: 7 criteria

Buying the “first available” curtains often leads to disappointment: they either do not fit, or interfere with the view in the mirrors, or quickly fail. To avoid errors, check:

Measure the height and width of the side windows (taking into account bends)

Check the compatibility of the mount with the type of paintwork on your car

Assess the level of light transmission (for daytime driving - at least 15%)

Make sure the curtains do not block your view of the side mirrors

Choose a material that is resistant to moisture (if you park outdoors)

Check the certificate of conformity (especially for electric models)

Compare reviews of a specific model on forums (for example, Drive2 or Auto.ru)

-->

Pay special attention sizes. For example, for Toyota RAV4 2020 front side curtain should not be narrower 45 cm, otherwise it will not cover the glass completely. For accuracy use laser roulette or a cardboard template.

If you choose magnetic curtains, check the thickness of your car's paintwork (you can measure thickness gauge). On vehicles with a thick layer of paint (e.g. Volkswagen Amarok) standard magnets may not hold - you will need models with neodymium magnets (adhesion force from 1.2 kg).

Step-by-step instructions: how to install curtains with your own hands

Installing most curtains does not require special skills, but there are nuances that affect the durability and reliability of the fastening. Let's look at the process using an example magnetic and roller blinds - the most popular options.

Magnetic curtains

For installation you will need: the curtains themselves, alcohol solution for degreasing, soft cloth.

1. Clean the surface of the body around the windows from dirt and grease (use isopropyl alcohol).
2. Attach the curtain to the glass and mark the places where the magnets are attached (they should be on metal body parts, and not on plastic moldings).
3. Attach the curtain starting with the top magnets. Make sure it doesn't move when pressed lightly.
4. Check your visibility in the mirrors: the curtain should not cover more than 20% mirror area (according to GOST R 51709-2001).

Roller blinds

Here the process is more complicated and requires tools: drill, drill 3–4 mm, Phillips screwdriver, silicone sealant.

1. Remove the door trim (carefully prying plastic spatula) to gain access to the interior.
2. Try on the curtain guides and mark the places for fastenings. For Toyota Camry Usually 4 attachment points are enough.
3. Drill holes and attach guides to self-tapping screws with press washer. Seal the edges to prevent corrosion.
4. Reinstall the trim and check the movement of the curtain - it should move smoothly, without jamming.

⚠️ Attention: When drilling into a door, avoid areas where electrical wires pass (such as speakers or power windows). To check use wiring detector or an electrical diagram for your model.

What to do if the curtain jams?

If the roller blind moves jerkily, the reasons may be:

1) Guide misalignment — check the fastenings and tighten the screws if necessary.

2) Contamination of the mechanism - clean the guides WD-40 and lubricate silicone grease.

3) Canvas deformation - if the curtain is bent, try straightening it by ironing it through a damp cloth at low temperature (max. 100°C).

Legal nuances: where you can drive with curtains and where you can’t

In Russia, the use of side curtains not prohibited at the legislative level, but there are restrictions prescribed in Traffic regulations (clause 4.3) and GOST R 51709-2001:

• 🚦 Visibility. Curtains must not impair visibility through the side mirrors by more than 20%. In practice this means that they can close no more than 1/5 glass area from the side of the mirror.
• 🔦 Light transmission. If the curtains are installed outside (for example, on cargo vans), their light transmittance must be at least 70% (like tinting). This rule does not apply to interior curtains.
• 🚓 Traffic police requirements. The inspector may require the curtains to be removed if they interfere with the inspection of the interior when checking documents (according to Art. 12.5 Code of Administrative Offenses).

In Europe the rules are stricter: in Germany and France Curtains on the front side windows are only permitted if they are completely transparent or removed while driving. B Italy For opaque curtains on the front windows you can get a fine of up to €150.

If you often travel abroad, choose removable models or curtains with adjustable transparency (for example, electrochromic, which darken on command).

Care and storage: how to extend the life of curtains

The service life of curtains depends not only on the material, but also on care. For example, fabric models without treatment they lose color within a season, and metallized may corrode upon contact with moisture. Follow these rules:

• 🧼 Cleaning. Wash fabric curtains by hand in warm water (max. 30°C) with a mild detergent (e.g. Vanish). For PVC curtains use spray for plastic (no abrasives!).
• 🌡️ Storage. Remove curtains for the winter if they are not frost-resistant (check the specifications). Store in a case, away from direct sunlight.
• 🔧 Prevention. Check the fastenings once a month: clean the magnets from metal dust, and lubricate the roller blind guides silicone grease.

For electric curtains additional rules:

• Do not leave them in the “closed” position for more than 2 weeks - this can deform the canvas.
• When washing your car, avoid direct contact with water on the control unit (usually located in the door panel).

⚠️ Attention: Never use products containing chlorine or acetone - they destroy the protective coating and lead to cracking of the material. To remove tough stains (such as bird droppings), use special cleaners for auto glass.

Top 5 mistakes when choosing and installing curtains

Even experienced car owners sometimes make mistakes that negate all the benefits of curtains. Here are the most common:

1. Buying universal curtains. They rarely fit perfectly - there are gaps left through which light and heat penetrate. Always choose a model for a specific car brand.
2. Ignoring the view in the mirrors. If the curtain covers more than 20% mirror area, this violates traffic rules and increases the risk of accidents when changing lanes.
3. Installation on a dirty surface. Magnets and suction cups do not adhere well to dusty or greasy glass. Always clean the surface alcohol before installation.
4. Using curtains while driving. Even if they are well secured, vibration and wind loads can cause them to move. It is better to remove the curtains before the trip.
5. Saving on material. Cheap curtains made of thin polyester fade within a season and do not protect against UV rays. Optimal budget - from 1500 ₽ per set.

If you have already bought curtains and are faced with a problem (for example, they move when you move), do not rush to throw them away. Often it saves the situation additional fixation:

• For magnetic curtains - add 3M double sided tape to the edges.
• For curtains with suction cups - apply to the edges silicone greaseto improve sealing.

FAQ: Answers to frequently asked questions about side curtains

Is it possible to drive with side curtains on the highway?

This is not prohibited by law, but not recommended. At a higher speed 80 km/h curtains with suction cups or magnets can fly off, and roller blinds can jam due to vibration. In addition, they impair visibility when overtaking. It is optimal to use curtains only when parked.

Which curtain material protects best from heat?

The most effective - metallized (reflect up to 95% UV rays) and carbon (combine strength and low thermal conductivity). Fabric models with UV protection (for example, Coolaroo) block until 90% heat, but let in more light.

Do I need to coordinate the installation of curtains with the traffic police?

No, if the curtains removable and do not change the design of the car. If you install stationary curtains (for example, mortise doors), this is considered a conversion - it will be required declaration of changes made.

Can curtains damage paintwork?

Yes, if they are attached with magnets or suction cups. Over time, magnets may leave microcracks on the paint, and the suction cups are vacuum marks. To avoid damage, use protective film on the attachment points or choose curtains with clips.

Which curtains are suitable for cargo vans?

For vans (eg Ford Transit or Gazelle Next) are optimal roller blinds on guides or stationary blinds. They withstand frequent use and protect the load from heat. Important: for vans with isothermal body choose curtains with a heat-reflecting coating.
