Standard sizes of popular insulation panels today

In fact, panels are manufactured in many different specifications and sizes, from thickness, length to width. If you do not understand these parameters, you can easily choose the wrong product, leading to difficulties in construction or failure to meet technical requirements. This article, Kosmos will help you understand the parameters panel size, as well as how to choose the most suitable type for the project. Let's follow the details below.

Panel size parameters

5 size parameters of the Panel include: Panel thickness, corrugated iron layer thickness, panel length and width, core density.

1. Panel thickness (mm): The common thickness of the Panel is from 50mm to 200mm, calculated from the top of the metal sheet to the bottom of the Panel. The Panel itself has a structure of 3 layers of metal sheet - PU - silver-coated fabric with the lowest thickness of 16mm.
2. Thickness of corrugated iron layer (mm): The thickness of the corrugated iron layer usually ranges from 0,3mm – 0,6mm. The two corrugated iron layers can have the same or different thicknesses, flexibly meeting the technical requirements and costs of each project.
3. Panel length (m): Standard Panel length is from 2,7m - 5m for normal applications, can be specially produced up to 12m for large projects. Panels are produced according to order size to limit joints and shorten installation time.
4. Panel Width (m): Because of the interlocking structure, the Panel width is divided into two types: product width (including the interlocking groove) and effective width (excluding the interlocking groove). For example: A panel with a width of 1070mm has an effective width of 1000mm, excluding the 70mm interlocking groove.
5. Core density (kg/m³): Specific gravity represents the density of the material in the core (EPS foam, PU, ​​mineral wool, etc.). The higher the specific gravity, the harder the panel, the better its load-bearing capacity and the less warping it will be. This parameter also determines the weight of the panel, thereby affecting the load on the floor and the structure's skeleton.

Size and specifications are important factors when choosing PanelThese parameters directly affect the construction ability, durability and sound and heat insulation efficiency.

5 popular panel sizes today

Knowing the standard size of the panel helps investors accurately calculate the volume of materials, thereby optimizing costs and construction progress.

Standard size of EPS Panel (corrugated iron – EPS – corrugated iron)

EPS Panel EPS foam layer has the advantage of being light (8 - 12kg/m²). EPS foam layer provides insulation with thermal conductivity of 0,035-0,040 W/m·K and low cost. EPS panels are often used for cold storage, factories and civil works such as houses and offices that require economy.

Some suggestions for choosing the right Panel for the project under construction

To choose the right Panel for your project, in addition to price, you also need to pay attention to factors such as soundproofing, heat insulation, and durability of the product you choose to buy.

• If your project requires good heat and sound insulation, you should choose panels with a thickness of about 7.5 to 10cm.
• For projects requiring high heat resistance, strength and durability such as outdoor projects, panels with a thickness of 0.4 to 0.5mm are the suitable choice.
• Do not choose panels with high density for projects that require weight such as renovating old houses or ceiling construction projects.
• Panel thickness of 50-150mm should be selected for cold storage depending on storage temperature. Specifically:
  • Freezer -18°C → 100–150mm.
  • Cool storage 0–5°C → 75–100mm.
  • Normal storage 10–15°C → 50–75mm.

Each project requires different panel sizes. Therefore, you need to carefully measure the appropriate size to avoid shortage or excess during construction.
