4 Advice to Choose a Micro Perforated Metal

1. Understand Your Soundproofing Needs

Before selecting a Micro Perforated Metal Sheet, it's crucial to assess your specific soundproofing needs. Consider the type of noise you wish to reduce and the location where the sheet will be used. You will find that the type of sound (e.g., low-frequency, high-frequency) has a significant impact on your selection. Micro perforations are engineered to help with sound absorption and can be essential in various applications, including acoustic panels and sound barriers.

2. Material Composition Matters

The material of the micro perforated metal sheet is vital for soundproofing performance. Common materials include:

• Aluminum - Lightweight and corrosion-resistant.
• Steel - Offers durability but heavier.
• Stainless Steel - Ideal for longevity in harsh environments.

Each material has its unique acoustical properties that can affect noise insulation. For example, aluminum sheets may excel in lightweight applications, while thick steel sheets might provide superior sound attenuation.

3. Consider Perforation Size and Pattern

The size and pattern of the perforations directly influence the acoustic properties of the metal sheet. For optimal soundproofing, a balance must be struck between perforation size and sheet density. A study shows that:

• Smaller perforations (2-3 mm) are effective for high-frequency noise.
• Larger perforations (4-10 mm) can help with low-frequency sound.

Refer to the following table for a clearer comparison:

Perforation Size Frequency Range Best Uses 2-3 mm High-frequency Music studios, offices 4-10 mm Low-frequency Theaters, industrial

4. Thickness and Density Are Key

The thickness of the micro perforated sheets is a critical factor for sound insulation. Thicker sheets typically provide better soundproofing characteristics. Deciding on the ideal density usually involves considering the environment where the sheet will be installed. A rule of thumb in soundproofing is that every additional 1 mm of thickness can reduce sound transmission by up to 5 dB.

5. Evaluate Installation Options

Lastly, consider how the micro perforated metal sheet will be installed. Different applications may require different installation methods:

• Mounting on walls: Great for acoustic panels.
• Ceiling fixtures: Effective for sound barriers.
• Free-standing structures: Versatile for various environments.

Flowchart for Your Installation Process

In conclusion, selecting the right micro perforated metal sheet for soundproofing involves a careful evaluation of your specific needs, material types, perforation characteristics, and installation methods. Keep these five points in mind to ensure that you are making an informed decision to effectively tackle your noise issues.

MESH TYPE

Choose from a wide variety of Square, Rectangular, Round mesh holes and Weaving, Welding, Punching types.

MESH SIZE

In addition to selecting an opening size, many Wire Mesh items also have a mesh size which is determined by measuring the number of openings per lineal inch from the center of one wire to the center of an adjacent wire. If perforating or expanding metal, please advise the holes size and shapes.

OPENING SIZE

Select the opening size of the Wire Mesh. Opening size is the clear space between wires and is measured from the inside of one wire to the inside of an adjacent wire. For rectangular opening items, a width and length opening measurement is required.

WIRE DIAMETER / WIRE GAUGE

Choose the Wire Mesh diameter thickness (in inches) or wire gauge. We provide more information on wire diameter and wire gauge equivalents in the link provided in the Charts section on the Wire Mesh resources landing page.

PERCENT OPEN AREA

Identify the percentage of open area desired in the Wire Mesh or Perforated Metal.

Select the opening size of the Wire Mesh. Opening size is the clear space between wires and is measured from the inside of one wire to the inside of an adjacent wire. For rectangular opening items, a width and length opening measurement is required.

SURFACE FINISHING/ TREATMENT

Select the primary material type including Aluminum, Bronze, Carbon Steel, Copper, Galvanized Steel or Stainless Steel, taking into consideration climate or environmental realities. Inventory is typically “mill finish” unless otherwise specified. Some items in inventory have a vinyl coating or can be powder coated. We provide more information on Primary Material Types and Product Finishes in the links provided in the Overview section on the Wire Mesh Resources landing page.

PRODUCT SIZE, FORM & QUANTITY

Determine the number of sheets and/or coils including cut-to-size pieces and stub preferences if applicable.

ACCESSORIES

Determine if Wire Mesh Accessories such as Angle, Flat Bar, or U-Edging framing solutions are required for your application.

APPLICATION

Product applications/uses include screens, partitions, facades on parking garages and buildings, cabinet inserts, enclosures, and more. We invite you to browse Wire Mesh applications in our Gallery.
