Protecting your car from precipitation, sun and mechanical damage is a key task for any owner. But when it comes to safety, a regular polycarbonate or metal canopy can become a potential threat. Canopies made of non-combustible materials not only prevent fire from short circuits or sparks, but also comply with the current fire safety standards of 2026. This is especially true for private houses, cottages and parking lots, where the risk of fire from electrical wiring, barbecues or neighboring buildings increases significantly.
In this article we will look at which materials really belong to the class NG (non-flammable) according to GOST 30244-94, how to correctly calculate the load on a structure, avoid errors during installation and save money without loss of reliability. And also - let's reveal the myth about “completely non-combustible” canopies: in fact, even certified materials can melt or deform at temperatures above 1000°C, but their task is not to support combustion and allow time for evacuation.
Why an ordinary canopy can be dangerous: real cases and statistics
According to the Ministry of Emergency Situations, in 2023, 18% of fires in private areas began in outbuildings, including sheds and garages. Main reasons:
- 🔥 Short circuit in lighting wiring or sockets under the canopy (34% of cases).
- 🌿 Dry grass or debris under the structure, ignited by a spark (22%).
- 🚗 Fuel leak from a car or storing fuel and lubricants next to a shed (15%).
- ⚡ Lightning strike into a metal frame without grounding (9%).
A practical example: in the Moscow region in 2022, 3 cars burned under a canopy made of sandwich panels with polyurethane foam insulation. The source of ignition was a barbecue installed 5 meters from the structure. An ordinary metal-tiled shed could not withstand temperatures of +800°C and collapsed after 12 minutes, blocking access to the cars. Non-flammable analogue from profiled sheet with mineral wool would have held out for at least 40 minutes - this would have been enough for evacuation.
⚠️ Attention: Even if your canopy is made of non-combustible materials, Storing gas, gasoline or oil cylinders underneath is strictly prohibited. According to the standards of SP 4.13130.2013, the distance from the canopy to open fire places (barbecues, stoves) must be at least 10 meters.
Fire safety classes of materials: what does the marking NG, G1, B1 mean?
In Russia there is a classification according to GOST 30244-94 and GOST 30402-96, where materials are divided into flammable (G) and non-flammable (NG), as well as flammability (B), smoke-forming ability (D) and toxicity (T). The following indicators are critical for canopies:
| Class | Description | Examples of materials | Suitable for canopy? |
|---|---|---|---|
| NG | Non-flammable (does not ignite even at +1000°C) | Glass, metal, porcelain tiles, pool corrugated sheets | ✅ Yes |
| G1 | Low-flammable (smolders without flame, combustion temperature <200°C) | Mineral wool, asbestos cement sheets, some types of fiber cement | ⚠️ Conditional (only with metal frame) |
| B1 | Low-flammability (ignite at temperatures >500°C) | Fire-resistant polycarbonate (with flame retardants), some composites | ❌ No (risk of melting) |
| D1 | Low smoke producing ability | Fiberglass, aluminum | ✅ Yes (paired with NG) |
Important: fire safety certificate must be issued by an accredited laboratory (for example, VNIIPO EMERCOM of Russia). If the seller shows a “certificate” without a FATR register number, it is a fake. You can check the authenticity on the website fatr.gov.ru.
TOP 5 non-combustible materials for canopies: pros and cons
The choice of material depends on the budget, climate and loads (snow, wind). Let's consider proven options with real reviews from owners.
1. Profiled sheet with polymer coating Printech NG or Grand Line Firewall
🔹 Pros: price from 600 rub/m², weight 5–7 kg/m², installation with self-tapping screws without special tools.
🔹 Cons: if the coating is damaged, corrosion begins; makes noise when it rains.
🔹 Service life: 15–20 years (if scratches are painted annually).
2. Fiber cement boards Cembrit or Eternit
🔹 Pros: class NG, does not rot, does not rust, imitates wood or stone.
🔹 Cons: fragility during transportation; weight 18–22 kg/m² (requires reinforced frame).
🔹 Service life: 30+ years.
3. Fiberglass Lightweight FR (fire resistant)
🔹 Pros: transmits 70% of light, weight 3–4 kg/m², class NG.
🔹 Cons: price from 2500 rub/m²; turns yellow over time.
4. Aluminum composite panels Alucobond A2
🔹 Pros: does not rust, can withstand +800°C, modern design.
🔹 Cons: price from 3500 rub/m²; requires professional installation.
5. Porcelain tiles Kerama Marazzi or Estima
🔹 Pros: absolutely non-flammable, frost-resistant (-60°C), does not fade.
🔹 Cons: weight 40–50 kg/m² (foundation required); price from 4000 rub/m².
If you choose a profiled sheet, give preference to brands with double-sided zinc coating (not less than 275 g/m²). This will protect the metal from rust even with deep scratches.
How to calculate the load on a canopy: snow, wind, weight of materials
An error in calculations can lead to the collapse of the structure in winter or during a hurricane. Use SNiP 2.01.07-85* "Loads and impacts":
- Snow load =
S = S₀ × μ, where:S₀— weight of snow cover (for Moscow = 180 kg/m², for Sochi = 50 kg/m²).μ- roof shape coefficient (for a single-pitched canopy = 1.0, for an arched canopy = 0.6).
W = W₀ × k × c, where:
W₀— standard value (for Moscow = 23 kg/m²).k— height coefficient (up to 5 m = 0.75).c— aerodynamic coefficient (for canopy = 1.4).
Calculation example for a 6×3 m canopy in the Moscow region (snow + wind):
Snow: 180 kg/m² × 1.0 = 180 kg/m²
Wind: 23 kg/m² × 0.75 × 1.4 ≈ 24 kg/m²
Total load: (180 + 24) × 18 m² = 3564 kg
Weight of materials (corrugated sheet): 7 kg/m² × 18 m² = 126 kg
Total: the frame must support ≥ 3700 kg.
⚠️ Attention: If the slope of the canopy roof is less than 20°, snow load increases by 30% — installation of snow guards or a heating system is required.

Step-by-step instructions for installing a non-combustible canopy
Consider installing a 6×3 m canopy from profiled sheet NG on a metal frame. It will take 2 people and 3-4 days of work.
Step 1: Foundation
For strip foundation:
- Mark the area with pegs, check the diagonals (they must match).
- Dig a trench 50 cm deep and 30 cm wide.
- Install the formwork, lay reinforcement Ø12 mm (cell 20x20 cm).
- Pour concrete M200, let dry for 7 days.
Step 2: Frame
Use profile pipe 60×60 mm (wall thickness ≥2 mm):
- 📏 Weld the frame around the perimeter, check with a level.
- 🔧 Install vertical posts in increments of 1.5 m, secure with anchor bolts.
- 🔨 Weld the roof trusses (slope 15–20° for self-cleaning from snow).
- Lay waterproofing (TechnoNIKOL or Izospan D).
- Lay the sheets overlapping 10–15 cm, starting from the bottom row.
- Secure with self-tapping screws neoprene gaskets (step 30–40 cm).
- Install end strips and gutters.
- Ignore metal frame grounding.
Without grounding, lightning or stray currents can damage the vehicle's electronics. Minimum requirement:
ground loop with resistance ≤4 Ohm. - Save on waterproofing.
Condensation under a corrugated sheet without a vapor barrier leads to rust of the frame within 3–5 years.
- Use wooden supports.
Even treated with fire retardants, they lose their properties after 5–7 years. Only allowed glued beams class G1.
- Fasten the sheets tightly.
The profiled sheet must “breathe” - leave a gap of 2–3 mm between the sheets and the frame.
- Neglect care.
Wash the canopy 2 times a year (spring and autumn) soft brush and car shampoo — abrasives scratch the coating.
- 📍 It is located on lands of individual housing construction or private plots.
- 🏠 Not adjacent to the house (distance ≥1 m).
- 🔥 Complies with fire safety standards (SP 4.13130.2013).
- 🔩 Bolted connections for frame (pipes with flanges).
- 🧱 Brick or concrete posts instead of metal ones.
- 📦 Ready-made arched structures (for example, canopies "Tunnel" from "Metal Profile").
- 🌨️ Profiled sheet NG (thickness 0.7 mm) withstands hail with a diameter of up to 25 mm.
- 🌨️ Fire retardant polycarbonate (thickness 10 mm) - up to 15 mm.
- 🌨️ Fiber cement - up to 30 mm (but may crack with a pinpoint impact).
- ⚡ Canopy above 3 m OR located in open area.
- ⚡ Within a radius of 50 m there are trees taller than 10 m.
- ⚡ Your region belongs to thunderstorm activity zone (for example, the Caucasus, the Urals).
- 🔥 Basalt wool (Rockwool, TechnoNIKOL>) - up to +1000°C.
- 🧱 Foam glass (Foamglass) - up to +500°C, does not absorb moisture.
- 🧊 Extruded polystyrene foam with fire retardants (labeling EPPS-NG) - up to +75°C.
Step 3: Roofing
For a profiled sheet:
How to avoid corrosion at pipe cut points
After cutting with a grinder, process the edges of the pipes zinc spray (for example, Zinc Spray from Loctite). Then cover two-component epoxy paint - this will increase the service life of the frame by 2-3 times.
5 mistakes that shorten the lifespan of your canopy
Even high-quality materials can quickly become unusable due to improper installation or operation. That's what can't do:
The most common cause of canopy collapse is lack of stiffeners on roof trusses. Even with the correct calculation of the load without diagonal braces, the frame “plays” in the wind and becomes deformed.
Cost of a canopy made of non-combustible materials: comparison of options
The price depends on the size, material and complexity of installation. Average prices for a 6×3 m canopy (2026):
| Roof material | Frame type | Turnkey cost (RUB) | Service life (years) |
|---|---|---|---|
| Profiled sheet NG (Grand Line) | Metal (pipe 60×60) | 85 000 – 120 000 | 15–20 |
| Fiber cement (Cembrit) | Metal reinforced | 140 000 – 180 000 | 30+ |
| Fire-resistant fiberglass | Aluminum profile | 180 000 – 250 000 | 20–25 |
| Porcelain tiles | Steel frame + foundation | 250 000 – 400 000 | 50+ |
Tip: If your budget is limited, save on self-assembly of the frame (video instructions are on the channel "StroyGarage"), but trust the roofing to professionals - mistakes when attaching sheets lead to leaks.
