When your project calls for an impermeable geomembrane,HDPE is often the gold standard. But simply ordering an “HDPE liner” is not enough. As a buyer, you must understand the specifications that dictate quality, longevity, and ultimately, value for money. Here‘s what to discuss with your non woven geotextile suppliers(many of whom also supply geomembranes) or specialized manufacturers.

Key Specification Points for HDPE Geomembrane Sheet

1.Resin Quality:

The heart of the product. Ask for virgin, high-quality resin (not recycled). This ensures consistent chemical resistance and long-term durability. The density should be ≥ 0.940 g/cm³.

2.Thickness & Tolerance:

Thickness (e.g., 1.0mm, 1.5mm, 2.0mm) directly relates to puncture resistance and longevity. Ensure the supplier guarantees a minimum thickness, not just an average. Tolerance should be tight (e.g., ± 5%).

3.Textured vs. Smooth:

Smooth hdpe liner sheet is standard. Textured geomembrane (on one or both sides) provides increased interface friction, crucial for slopes. This prevents the liner from sliding. Specify based on slope design.

4.Carbon Black Content & UV Stabilization:

For exposed applications, the sheet must contain 2-3% carbon black (evenly distributed) and UV stabilizers. This prevents degradation from sunlight. Ask for relevant test reports (e.g., ASTM D7238 for oxidative induction time).

5.Panel Size & Seam Integrity:

Larger factory-fabricated panels mean fewer field seams, reducing potential leak points. For seams, inquire about the welding procedure specification (WPS) and the qualification of welders.

Beyond the Sheet: The System Approach

An hdpe geomembrane sheet is part of a system. It needs protection. This is where non woven geotextile fabric comes in as a critical cushion layer. A reputable supplier will not just sell you the membrane but advise on the complete system, including the appropriate geo fabric material for protection and a potential GCL liner for a composite system.

Procurement Action Plan

Do notbuy on price alone.
Dorequest certified test reports for resins and finished sheets.
Doask for project references and case studies.
Doconsider the supplier‘s technical support and ability to provide a system solution.

Investing in a properly specified HDPE geomembrane from a quality-conscious manufacturer prevents costly failures and protects your project’s environmental and structural integrity.

If you're planning to create a modern home theater or stylish living room, you might be wondering:

"Can I mount the TV directly on a sound-absorbing wall?"

In short: It's not recommended.

Here are the reasons and the correct installation method.

❌ Why you shouldn't mount a TV directly on a sound-absorbing panel

Sound-absorbing panels—especially felt-backed wooden slats—are for absorbing sound, not for bearing weight.

Mounting a TV directly on acoustic panels may result in:

Insufficient structural support

Risk of panel damage

Unsafe installation

Degraded acoustic performance

✔ Correct way to install a TV using acoustic panels

You can perfectly combine a TV wall mount with acoustic panels—simply follow these steps:

1. First, mount the TV bracket on a solid wall.

The TV should be securely fixed to the following wall surfaces:

Concrete wall

Brick wall

Use suitable anchors to secure to drywall

Wooden frame

2. Install the acoustic panels around the bracket.

Leeyin's wood slat acoustic panels are precisely cut to perfectly fit the wall mount, providing a seamless, high-quality look.

3. Hide cables behind the panel.

Our panels have small gaps between the wood slats and felt backing—perfect for concealing cable management.

Want to improve the acoustics of your room but don't have traditional acoustic panels on hand?

Here are some alternatives that can help reduce echoes and improve sound quality—although none of them can match the performance of professional acoustic panels.

✅ 1. Heavy Curtains

Thick fabrics help absorb mid-to-high frequency sounds.

Perfect for living rooms and bedrooms.

✅ 2. Rugs

Bare floors reflect sound. Laying down a soft rug can instantly reduce echoes.

✅ 3. Bookshelves Filled with Books

Bookshelves filled with books both diffuse and absorb sound—simple and effective.

✅ 4. Upholstered Furniture

Sofas, upholstered chairs, and cushions themselves absorb sound waves.

✅ 5. Homemade Foam Boards

While convenient, they are usually not dense enough and have poor fire resistance.

What Exactly Does Acoustic Panel Do? A Beginner's Guide

If you've ever experienced echoes, noise build-up, or unclear sound in a room, then you've encountered an acoustic challenge. With the growing interest in home studios, modern offices, and high-quality interior design, more and more people are starting to wonder about a simple question: What exactly does an acoustic panel do?

In this beginner's guide, we'll explain how acoustic panels work, what problems they can solve, and how to choose the right solution for your space, from the perspective of a professional acoustic panel manufacturer.

What is an Acoustic Panel?

Acoustic panels are specially designed engineered products designed to control indoor sound. They help reduce echoes, reverberation, and excessive noise reflection by absorbing sound waves, especially mid-to-high frequencies.

Unlike exposed walls, glass, or concrete surfaces that reflect sound, acoustic panels convert sound energy into heat energy through porous materials, such as:

Sound-absorbing PET fibers

High-density MDF boards with felt backing

Mineral wool or sound-absorbing core materials

These materials are commonly used in wood slat wall panels, fabric panels, and decorative acoustic systems.

What are the actual functions of acoustic panels?

1. Reduce Echoes and Reverberation

One of the main functions of acoustic panels is to reduce reverberation time. In an untreated room, sound reflects repeatedly between hard surfaces, creating echoes and a muddy sound. Acoustic panels absorb these reflections, creating a clearer, more controlled acoustic environment.

This is especially important in the following settings:

Home theaters

Music studios

Meeting rooms

Dining rooms and open-plan offices

2. Improve Sound Clarity

By reducing unwanted reflections, acoustic panels improve speech clarity and audio detail. Conversations are easier to understand, music sounds more balanced, and auditory fatigue is reduced.

This is why acoustic panels are widely used in:

Recording studios

Podcast recording studios

Classrooms and training centers

Business meeting spaces

3. Enhance Acoustic Comfort (Not Complete Soundproofing)

People often mistakenly believe that acoustic panels completely block noise from entering and leaving a room. In reality, acoustic panels are designed to absorb sound, not completely isolate it.

They help to:

Reduce indoor noise buildup

Minimize sound reflections

Improve indoor acoustics

To achieve complete sound insulation, additional construction methods such as massing, vibration damping, and sealing are required. However, acoustic panels are a cost-effective and essential first step in most acoustic treatments.

Where are acoustic panels commonly found?

Acoustic panels are suitable for residential and commercial spaces, including:

Living rooms and home theaters

Bedrooms and apartments

Offices and coworking spaces

Hotels, lobbies, and restaurants

Recording studios, rehearsal rooms, and broadcasting studios

In modern interior design, wood slat acoustic wall panels are favored for their combination of sound absorption and modern aesthetics.

Why are wood slat acoustic panels so popular?

Wood slat wall panels achieve a unique balance between design and performance. The strip-shaped medium-density fiberboard (MDF) surface diffuses sound, while the sound-absorbing felt backing absorbs noise, making it both practical and beautiful.

Advantages include:

Highly efficient sound absorption

Warm and modern appearance

Easy wall or ceiling installation

Customizable colors, finishes, and sizes

Specialized manufacturing processes ensure superior quality

The performance of sound-absorbing panels depends heavily on material quality, density, and manufacturing precision.

Are Cold Storage Panels Essential for Seafood Warehouses? (You Bet!)

2025-12-19 - tags：PIR Sandwich Panel for Cold Room PU PIR Sandwich Panels Pu Sandwich Panel for Cold Room cold room panel suppliers cold room panels for sale cold room panels manufacturer cold room panels near me cold room sandwich panel

Keeping seafood super-fresh needs seriously cold storage. Regular walls just not suitable! That's where specialized cold storage panels come in –they're absolutely essential for any seafood warehouse wanting top-quality fish and shellfish. Think of them as the super-insulated armor locking in the cold and keeping spoilage out.

The Heart of the Cold Room: PU/PIR Sandwich Panels

The Best Choice for seafood cold rooms are PU/PIR: 0.02 W/(M·K) sandwich panels. Why? Their secret weapon is the super-dense, closed-cell foam core. This core acts like a powerful barrier, slashing energy bills by keeping cold air in and warm air out far better than other options. It also makes the panels strong and rigid, perfect for building large, reliable cold storage spaces. Propanel’s engineers these cores for maximum thermal efficiency, giving you cold you can count on.

Getting the Thickness Right Matters

No.	Fish Species	Temperature Requirement (°C)	PU Panel Thickness (mm)
1	Shellfish (e.g., Mussels, Oysters)	0 to 5	75
2	Fresh Fish (e.g., Cod, Haddock)	-5 to 0	100
3	Frozen Shrimp, Crab, Lobster	-15 to -30	150
4	Fatty Fish (e.g., Salmon, Mackerel)	-18 to -24	120
5	Tuna (High-Quality)	-45 to -60	200

Notes:

-Fresh fish require near 0°C for short-term storage (1-2 days) to prevent bacterial growth.

-Fatty fish need lower temperatures to preserve oils and flavor.

-Tuna demands ultra-low temperatures to maintain premium quality.

-PU panel thickness ensures thermal insulation and energy efficiency, with thicker panels for lower temperatures to minimize heat transfer.
