🧱 What Are 3D Wall Panels?
If you're looking to add character, texture, and depth to your walls, 3D wall panels might be the upgrade your interior has been waiting for. Whether you're styling a living room feature wall or soundproofing a stylish home office, these sculptural panels turn plain surfaces into design statements.
From modern waves to geometric shapes and elegant patterns like SANDGLASS or STRIPES 2, 3D wall panels have become a go-to solution for both residential and commercial interiors.
🛠️ How to Install 3D Wall Panels
Wondering how to install 3D wall panels without hiring a pro? Good news: many 3D wall panels, especially lightweight options like EPS (expanded polystyrene), are DIY-friendly.
Step-by-step:
- Clean the wall surface (dry, flat, dust-free)
- Plan the layout (use a laser level or ruler)
- Apply adhesive (like Penosil Tube Adhesive)
- Press panel into place and hold briefly
- Fill gaps if needed
- Paint optional
Lightweight EPS panels, like those in the 3D Polystyrene Wall Panels Collection, are designed for quick mounting - even on ceilings!
🎨 Can 3D Wall Panels Be Painted?
Yes, 3D wall panels can absolutely be painted. Polystyrene panels come with a raw, matte surface designed for customisation. We recommend using water-based paints (avoid solvent-based ones which may damage the EPS).
Paint tips:
- Use a roller for large surfaces
- For details and grooves, try a brush or spray
- Choose matte, satin, or eggshell finishes for best results
Painting your panels lets you match them perfectly to your room’s palette, or highlight their texture with contrasting tones.
🛋️ 3D Wall Panels for Living Room: Ideas & Inspiration
3D wall panels for living room spaces are especially popular as feature walls. They provide visual rhythm, hide imperfections, and soften acoustics - all while elevating your style.
Here are some layout ideas:
- Behind the TV unit (sound-absorbing, glare-reducing)
- Around a fireplace for layered texture
- As a sofa backdrop for depth and dimension
- In a niche or under stairwells for surprise details
Mix panel styles across adjacent walls for a contemporary twist, or go full ceiling-to-floor for immersive texture.
🔇 Are 3D Wall Panels Soundproof?
Not exactly, but they are sound-absorbing. While not classified as full soundproofing solutions, EPS 3D wall panels can reduce echo, soften ambient noise, and improve speech clarity - especially helpful in living rooms or offices with hard floors and minimal furniture.
Panels like SANDGLASS 3D Polystyrene Wall Panels are made from durable, high-density foam that improves acoustic comfort while looking stunning.
If you’re serious about acoustics, pair them with curtains, rugs, or acoustic felt for maximum effect.
