At Your Doorstep
Roll, not tiles - cut it to your job
Same 2 lb/sq ft Mass Loaded Vinyl as our pre-cut tile pack (KK1246) - but in one big 1 m x 1 m (39 x 39 in) sheet so you can cut to whatever shape you need. Door panels, vehicle floors, behind drywall, around outlets and pipes - the roll lets you waste less and fit better.
How Mass Loaded Vinyl works
Noise has one big enemy: mass. The denser the surface, the less sound passes through. Most apartment walls, hollow doors, and car panels don't have enough mass - that's why you can hear the neighbor's TV, traffic on the freeway, or your washing machine three rooms away.
This sheet is 2 lb/sq ft (9.8 kg/m²) - the same weight pros spec into recording studios and home theaters. The full 1 m x 1 m sheet weighs about 22 lb (9.8 kg). That mass is what blocks airborne sound.
- Lay or stick the sheet on the noisy surface - drywall, door, floor, ceiling, vehicle panel.
- Cut to fit with scissors or a utility knife. No power tools.
- Cover or paint if you want a finished look - or leave it bare in a closet, garage, or vehicle.
Result: a measurable drop in noise transmission within an hour of opening the box.
What the numbers mean
What's in the box
- 1 sheet, 1 m x 1 m (39 x 39 in)
- Coverage: ~10.8 sq ft (1 m²)
- Weight: ~22 lb (9.8 kg)
- Surface weight: 2 lb/sq ft (9.8 kg/m²)
Install in 3 steps
- Measure the area you want to quiet. Mark the sheet on the back side with a marker.
- Cut to fit with scissors or a utility knife. The sheet conforms to curves and corners.
- Apply with double-sided tape, construction adhesive, staples, or screws. For doors and machinery, peel-and-stick acoustic tape works fine.

Apartments with noisy neighbors, home theaters, recording and podcast studios, vehicle floors and doors, noisy washing machines and HVAC units, home offices on busy streets, bedrooms next to a freeway, nurseries, hotels, classrooms, conference rooms, and houses of worship.

FAQ
▾ Should I get the roll or the pre-cut tiles?
Get the roll (this product) if you're covering a continuous area like a whole door, behind drywall, or a vehicle floor - you'll waste less material. Get pre-cut 12 x 12 in tiles (KK1246) if you're spot-treating a small area or want to add tiles one at a time.
▾ Do I need a contractor to install this?
No. Most customers install it themselves with scissors and double-sided tape in under an hour. The sheet is heavy (~22 lb / 9.8 kg) so two people make it easier on a wall or ceiling.
▾ How do I cut a 1 m x 1 m sheet?
Lay it flat, mark the cut line on the back with a marker, then cut with sharp scissors or a utility knife against a straight edge. It cuts cleanly without splintering.
▾ Will it block my neighbor's bass or subwoofer?
It will reduce it. Low-frequency bass is the hardest noise to block; for heavy bass, layer 2 lb/sq ft MLV behind drywall with an air gap. Mid and high frequencies are blocked dramatically - STC 31-33 turns loud speech into a muffled murmur.
▾ Is 2 lb/sq ft heavy enough for shared apartment walls?
Yes. 2 lb/sq ft is the industry-standard MLV weight pros use behind drywall in recording studios. For thin shared walls, layer it on top of the existing drywall and add an acoustic underlay if possible.
▾ Does it smell?
No. Low-emission, non-toxic, fire-retardant. Safe for bedrooms and nurseries.
▾ Can I paint it or cover it with fabric?
Yes. Most customers cover with fabric, drywall, or acoustic foam panels for a finished look. The black color works fine bare in garages, basements, and vehicles.
▾ Will it stick to a brick wall?
Use construction adhesive on brick or concrete. Double-sided tape, staples, and screws work for drywall, doors, and metal.
▾ How many sheets cover one wall?
An 8 ft x 10 ft wall (~2.4 x 3 m) is about 80 sq ft (~7.2 m²) - that's about 8 sheets. For most apartment walls, 2-4 sheets covers a focused trouble spot.
▾ Is it waterproof?
Yes. Safe in basements, garages, vehicles, and laundry rooms.
▾ Can I return it if it doesn't work?
Yes - 100-day returns on unused, sealed sheets. Email service@arrowzoom.com with your order number.

What's the difference between impact and airborne noise? 🔊
What's the difference between impact and airborne noise? 🔊
1. Airborne Noise
- This travels through the air, like conversations, TV sounds, or barking dogs. When sound waves hit a building, they cause it to vibrate, transmitting through the structure.
2. Impact Noise
- This results from physical impacts on buildings, such as footsteps, slamming doors, or moving furniture. Impact noise can be harder to isolate, as these vibrations are stronger and travel further through dense materials.
What are decibels? 📏
What are decibels? 📏
Decibels are measured logarithmically (not as a percentage) . This means that every increase of 10dB on the scale is a tenfold increase in sound pressure level (SPL) . Near silence is 0dB 🤫, while a sound at 10dB is ten times louder!
- 30-40 dB = Soft music, whisper 🎶
- 60-80 dB = Office noise, traffic 🚗
- 85-100 dB (HARMFUL) = Subway, shouted convo, chainsaw ⚠️
- 100-140 dB (DANGEROUS) = Chainsaw, loud concert, racing, shooting range 🚨
