How much do sandwich panels cost for a garage: prices, calculation and selection

Construction of a garage from sandwich panels - one of the fastest and most economical ways to get a reliable shelter for your car. These materials combine the strength of metal, thermal insulation and ease of installation, making them an ideal choice for private developers. However, before purchasing, it is important to understand the prices: what they depend on, what types of panels exist and how to calculate the final cost of the project.

In 2026, the market offers a wide range of sandwich panels with different thicknesses, cores and coatings. Price may vary from 1,200 to 4,500 rubles per square meter depending on technical specifications and manufacturer. In this article we will analyze in detail all the factors that influence the cost, compare popular brands and give practical recommendations on choosing materials for the garage.

Factors affecting the cost of sandwich panels

The price of sandwich panels is determined by several key parameters. The first thing you should pay attention to is filler type. The most budget options have mineral wool or polystyrene foam, while panels with PUR/PIR foam (polyurethane/polyisocyanurate) are significantly more expensive, but provide better thermal insulation and fire resistance.

The second important factor is panel thickness. For a garage, 80–150 mm is usually sufficient, but if you plan to heat the room or live in a region with harsh winters, panels with a thickness of 200 mm or more will be required. The price is also affected by:

• 🔹 Coverage type: galvanized steel is cheaper than aluzinc or polymer coating (Plastisol, Pural)
• 🔹 Manufacturer: Russian brands (Thermopane, Sandwich Profile) cheaper than European ones (Ruukki, Kingspan)
• 🔹 Additional options: tongue-and-groove locking connection, perforation for ventilation, decorative finishing
• 🔹 Order quantity: wholesale quantities (from 100 m²) cost 10–20% cheaper than retail ones

No less important is garage design. A frame structure with a straight roof will require less materials than an arched or attic version. It is also worth considering the need to purchase additional elements (corners, strips, seals), which can add 15–25% to the final cost.

Comparison of prices for popular types of sandwich panels

To get an idea of market prices, let’s consider the average cost of panels of different types for 2026. The data is relevant for the Moscow region and may differ in other cities (increasing or decreasing by 10–15%). All prices are per 1 m² excluding delivery and installation.

Panel type	Thickness, mm	Filler	Price, rub/m²	Application
Wall standard	80–100	Mineral wool	1 200–1 800	Unheated garages, summer buildings
Wall premium	120–150	PUR/PIR foam	2 500–3 500	Heated garages, workshops
Roofing	100–120	Expanded polystyrene	1 800–2 400	Flat and pitched roofs
Roofing reinforced	150–200	Basalt wool	3 000–4 500	Arched structures, snowy regions
Decorative (wood/brick)	80–100	Expanded polystyrene	2 200–3 000	Facade finishing, extensions to the house

Please note that roofing panels are always more expensive than wall ones due to increased requirements for strength and moisture resistance. For example, roof panels often have an additional layer of waterproofing and reinforced fastening of locks. The price may also include profiling (wavy or trapezoidal surface), which improves rigidity and snow retention.

⚠️ Attention: Cheap panels with expanded polystyrene (< 1,500 rubles/m²) often have low fire resistance (class G3–G4). For a garage where fuels and lubricants are stored, it is better to choose materials with class NG (non-flammable) or G1 (low-flammable).

Calculation of the number of panels for a garage

In order not to overpay for unnecessary materials, it is important to correctly calculate the required number of panels. For this you will need:

• 📏 Garage dimensions (length, width, height)
• 🔺 Roof type (single-pitched, double-pitched, arched)
• 🔄 Number of openings (gates, windows, doors)

Let's consider an example calculation for a standard garage measuring 6×4×2.5 m with a pitched roof:

1. Walls: Perimeter = (6 + 4) × 2 = 20 m. Area = 20 × 2.5 = 50 m². Subtract the area of the gate (usually 2.5 × 2.2 = 5.5 m²). Total: 44.5 m².
2. Roof: Area = length × width × cosine of the angle of inclination (for a lean-to ~1.1). 6 × 4 × 1.1 ≈ 26.4 m².
3. Additional elements: Corners (4 pieces, 2.5 m each), junction strips (10 m), seals (20 m).

In total, this garage will require about 70–75 m² panels (with a 10% margin for trimming). If you use wall panels at 2,000 rubles/m² and roofing panels at 2,500 rubles/m², then the cost of materials will be:

Walls: 44.5 m² × 2,000 rubles = 89,000 rubles
Roof: 26.4 m² × 2,500 rubles = 66,000 rubles
Extras: ~15,000 rub.
TOTAL: 170,000 rub.

For convenience, you can use online calculators on manufacturers’ websites (Thermopane, Metal Profile), which take into account all the nuances of the design. Do not forget to add 10-15% margin for adjustment and possible defects during installation.

Where to buy sandwich panels: comparison of suppliers

Prices for sandwich panels can vary significantly depending on the place of purchase. Let's look at the main options:

• 🏭 Manufacturing plants: The lowest prices (10–20% cheaper), but large wholesale is often required (from 500 m²). Examples: Sandwich Panel Plant (Moscow), Termopan (St. Petersburg).
• 🏪 Construction hypermarkets: Convenient for retail buyers, but prices are 15–30% higher. Examples: Leroy Merlin, OBI, Castorama.
• 🚛 Online platforms: Prices are close to factory prices, but review reviews are required. Popular sites: Tiu.ru, Stroypartner, All.biz.
• 👷 Turnkey companies: 25–40% more expensive, but includes installation and warranty. Examples: GarageStroy, Modular Garages.

When choosing a supplier, pay attention to:

• 📄 Availability of certificates of conformity (GOST, SNiP)
• 🔄 Possibility of returning or exchanging defective panels
• 🚚 Cost and delivery conditions (some companies offer free delivery from 50 m²)
• 🛠️ Availability of installation teams (if you plan to order installation)

⚠️ Attention: When purchasing through intermediaries, request a quality certificate for a batch of panels. Unscrupulous sellers may offer “economy” options with a lower filler density (for example, mineral wool 60 kg/m³ instead of the standard 110 kg/m³), which worsens thermal insulation by 30–40%.

Hidden costs: what else will you need money for?

In addition to the panels themselves, building a garage from sandwich structures will require additional investments. Here are the main expense items that are often overlooked:

Expense item	Cost, rub	Notes
Foundation (strip/slab)	50 000–150 000	Depends on soil type and freezing depth
Frame (metal/wooden)	30 000–80 000	For panels with a thickness of 100–150 mm
Floor insulation	15 000–40 000	Penoplex or expanded clay with a layer of 100 mm
Gates (sectional/hinged)	25 000–100 000	Includes automation and insulation
Electrical wiring and lighting	10 000–30 000	Including sockets and switches

Also don't forget about delivery (from 5,000 to 20,000 rubles depending on the distance) and installation (from 800 to 1,500 rubles/m²). If you plan to build a garage yourself, consider the costs of tools:

• 🔧 Screwdriver with attachments for metal screws (~5,000 rubles)
• 📐 Laser level or level (~3,000 rubles)
• 🔨 Metal scissors or jigsaw (~2,500 rubles)
• 🧲 Seam sealant (~1,500 rubles per tube)

Saving without losing quality: 5 proven ways

You can reduce the final cost of a garage made of sandwich panels without compromising strength and thermal insulation. Here are working recommendations:

1. Buy in the off-season. Demand for building materials falls from November to February, and many suppliers offer discounts of up to 15%. The exception is December (pre-New Year rush).
2. Choose combination panels. For example, for walls - mineral wool (cheaper), for the roof - PUR (more expensive, but more reliable). This will save up to 20% of your budget.
3. Order standard sizes. Panels 6 or 12 m long are cheaper than non-standard ones (for example, 5.8 m). Adjust the dimensions of the garage to the factory dimensions.
4. Use galvanized extensions. Aluminum or polymer corners cost 2–3 times more, but galvanized steel is quite sufficient for a garage.
5. Install it yourself. If you have the skills to weld and work with tools, you can save up to 40% of your budget. For a 6x4 m garage, turnkey installation costs 50,000–70,000 rubles.

Another way to save money is to buy panels with factory defect (substandard). Such materials are sold at a 30–50% discount, but have defects in coating or geometry. They can be used for interior walls or under cladding.

Where to look for substandard panels?

In the warehouses of manufacturing plants (section "Discounted Goods") or through telegram channels of wholesalers. For example, in @StroyDiscount_Msk batches of sandwich panels with minor defects regularly appear at prices starting from 800 rubles/m².

Owner reviews: pros and cons of garages made of sandwich panels

To objectively assess the feasibility of building a garage from sandwich panels, let’s study the experience of real owners. We analyzed reviews on the forums (Drive2, GarageForum.ru) and highlighted the key points:

Pros:

• ✅ Construction speed: A 6x4 m garage can be assembled in 3–5 days (including the foundation).
• ✅ Thermal insulation: With a thickness of 150 mm, the temperature inside in winter is 10–15°C higher than outside.
• ✅ Ease of modification: It's easy to add a window, door or ventilation without removing walls.
• ✅ No shrinkage:

Cons:

• ❌ Poor sound insulation: Rain or hail is heard inside the garage. The solution is additional sound insulation (for example, Schumanet-ECO).
• ❌ Risk of corrosion: If the coating is damaged, the metal rusts. It is necessary to treat the cuts with an anticorrosive agent.
• ❌ Limited load: Heavy shelves (max 50 kg/m²) must not be hung on walls.
• ❌ Fastening problems: Self-tapping screws become loose over time. The solution is to use rivets or bolts.

According to a survey on Drive2, 78% of owners of garages made of sandwich panels are satisfied with the choice and recommend this material. The main complaints concern installation: 45% of respondents experienced leaks due to poor-quality sealing of seams. Therefore, if you hire a crew, be sure to check the reviews and portfolio of their work.

FAQ: Frequently asked questions about sandwich panels for garages

Is it possible to build a garage from sandwich panels without a foundation?

Technically yes, but only for temporary structures. A permanent garage requires at least a lightweight foundation (for example, screw piles or monolithic slab 100 mm thick). Without a foundation, a garage can sag or warp when exposed to wind.

Which filler is best for a heated garage?

Optimal choice - PUR/PIR foam (polyurethane). It has the lowest thermal conductivity coefficient (0.022 W/m K) and flammability class G1. An alternative is basalt wool (NG class), but it is heavier and requires additional waterproofing.

How long will a garage made of sandwich panels last?

The service life depends on the quality of materials and installation:

• Budget panels (expanded polystyrene, galvanized) - 10–15 years.
• Premium panels (PUR, aluzinc) - 25–30 years.
• With proper sealing of seams and anti-corrosion treatment, the service life increases by 20–30%.

Is it possible to paint sandwich panels?

Yes, but only with special paints for metal (for example, Hammerite or Tsikrol). Conventional enamels peel off after 1–2 years. Before painting, the surface must be cleaned of dirt and degreased. It is better to paint in dry weather at a temperature of +10…+25°C.

How to insulate a garage floor using sandwich panels?

Recommended scheme:

1. Compacted soil + sand cushion (100 mm).
2. Penoplex or extruded polystyrene foam (50–100 mm).
3. Reinforced screed (50–70 mm) or OSB board flooring.

For regions with frosts below -20°C it is better to use expanded clay concrete (layer 150 mm).
