How to Remove Wrinkles and Creases from Acoustic Fabric

If you’re building DIY acoustic panels or working with acoustical fabric, you may notice wrinkles or creases from folding, shipping, or storage. The good news is that acoustic fabric is designed to be easy to work with and wrinkles are simple to remove.

Why Acoustic Fabric Wrinkles

Most acoustic fabrics are made from polyester, which can develop creases when folded or compressed. This is completely normal and does not affect performance.

Acoustic fabric is designed to smooth out during installation when stretched properly.

Method 1: Let Tension Do the Work (Best Option)

The easiest and most effective way to remove wrinkles is during installation.

When you stretch the fabric tightly across a frame, the tension naturally smooths out creases and folds.

  • Start stretching lengthwise first
  • Staple gradually while maintaining tension
  • Start stapling in the middle and work your way to the corners
  • Avoid leaving slack in the fabric

In most cases this method alone will eliminate wrinkles completely.

Method 2: Iron on Low Heat

You can iron acoustic fabric if needed, but it must be done carefully.

  • Use the polyester/synthetic setting
  • Avoid direct contact with high heat
  • Place a pressing cloth between the iron and fabric

Too much heat can damage polyester so always keep the temperature low.

Method 3: Use a Dryer (Quick and Easy)

A dryer can help loosen wrinkles before installation.

  • Get fabric a little damp
  • Place fabric in the dryer on low heat or permanent press
  • Run for a short cycle (10–15 minutes)
  • Remove promptly to prevent new wrinkles

Method 4: Use a Garment Steamer

  • Use a handheld garment steamer
  • Keep the steamer moving to avoid overheating
  • Do not oversaturate the fabric

Steam relaxes the fibers and helps wrinkles fall out naturally.

Thing To Avoid

  • Do not use high heat
  • Do not leave fabric sitting in the dryer after a cycle
  • Do not apply steam or heat in one spot for too long

Frequently Asked Questions

Do acoustic panels really work? ▶
Yes, acoustic panels absolutely work when used correctly. Acoustic panels are designed to absorb sound waves, which helps reduce echo, reverb, and unwanted reflections in a room. This creates a cleaner, more controlled sound environment.

Whether you’re treating a home studio, podcast room, home theater, or office space, acoustic panels can make a noticeable difference in speech clarity, mix accuracy, and overall listening quality.
How do I know which panels are right for my room? ▶
Every space is unique. You can contact us for a free room analysis, or check out our guides under the “Learn” section.

Absorption panels help reduce echo and reverb. We offer foam panels and fabric covered panels.

Diffusers scatter sound for a more balanced feel.

Bass traps help control low frequencies that tend to build up in corners.

If you’re trying to block sound from entering or leaving a room, you’ll need soundproofing materials, which are different from acoustic treatments.
Can I order samples? ▶
Yes, we offer acoustic foam samples and well as fabric color swatches. If you are looking for something else please Contact Us.

What’s the difference between soundproofing and acoustic treatment? ▶
Soundproofing blocks sound from entering or leaving a room. Acoustic treatment improves sound inside the room by reducing echo and reverb.
Can acoustic panels improve speech clarity? ▶
Yes! Acoustic panels are commonly used in offices, conference rooms, and classrooms to reduce echo and improve speech intelligibility. By absorbing excess sound and reverb, panels make it easier to hear and understand spoken words—even at lower volumes.

Do acoustic panels block outside noise? ▶
Standard acoustic panels don’t block sound—they absorb it. Acoustic panels reduce echo and reverb inside a room but won’t stop external noise from entering or leaving.

If you’re looking for soundproofing, you’ll need materials designed to block sound transmission like mass loaded vinyl, or decoupled wall systems. We offer select products for this—Contact Us to learn more.

Where should I place acoustic panels? ▶
The best placement depends on your room and goals. For general echo reduction, aim to cover 20–30% of your wall space. For recording studios, home theaters, or listening rooms, focus on:

• Front wall behind speakers
• Back wall behind the listening position
• Side wall reflection points
• Ceiling above your desk or seating area
• Diffusers at key reflection points for natural sound

Do these panels work for podcasting, streaming, or music production? ▶
Absolutely. We serve customers across all industries — from home offices to professional studios.
What fabric is best for wrapping acoustic panels? ▶
To get the best sound performance, use acoustically transparent fabric—material that lets sound pass through easily. A simple test: try breathing through the fabric. If air flows freely, it’s likely a good choice. Avoid dense materials like heavy denim or canvas, as they can block sound instead of letting it be absorbed.
