Arrowzoom Acoustic Putty Pads for Electrical Boxes – Seal Gaps, Stop Noise Leaks, Fire-retardant (KK1478)

How the putty pad works Electrical outlets are "holes" in your wall that act like direct tunnels for noise. Even a soundproofed wall will fail if the sockets aren't treated. This pad wraps the back of the box to seal the leak. 1. High-Mass Intumescent Material: The dense putty adds critical mass to thin plastic or metal outlet boxes, reflecting sound back instead of letting it pass through. 2. Acoustic Sealing It creates an airtight gasket around wires and box edges, stopping the "flanking" noise that bypasses your insulation. 3. Fire Retardant works on any standard interior door, hollow-core or solid, single-side or both sides. Result: Restores the sound-blocking integrity of your wall (STC rating) in under 5 minutes. What the numbers mean STC Improvement +5 to +10 — Restores the wall's performance to its original rating by sealing the most common "weak link" in room construction. UL 263 Classified — Tested to maintain the fire resistance of wall assemblies for up to 2 hours. Honest note: utty pads are essential for wall soundproofing but work best when used on both sides of a shared wall (back-to-back outlets) and paired with wall insulation. What's in the box 12 , 24 or 48 Putty Pads . Each panel is 15x20x0.3cm (6 x 8 x 0.12in) Pre-applied self-adhesive backing on every panel Step-by-step install guide Simple 4-Step Installation Remove: Take off the outlet faceplate (ensure power is off if touching wires). Peel: Remove the protective paper from the putty pad. Mold: Wrap the pad firmly around the back and sides of the electrical box. Seal: Press the edges to create an airtight bond against the drywall, then replace the faceplate. No drill. No nails. No contractor. Made for Electrical outlet boxes · Light switch boxes · Junction boxes · Metal and plastic electrical boxes · Home theaters · Offices · Apartments · Recording studios · Commercial buildings Frequently asked questions Will this stop a noisy neighbor?? Partially. Putty pads are a critical component of a soundproofing system. They stop noise from leaking through electrical outlets—the most common "weak link" in a wall. While they won't block 100% of the noise on their own, they prevent sound from bypassing your wall insulation. For maximum reduction, treat the outlets on both sides of the shared wall.. Does this pad fit all electrical boxes? Yes. The putty is highly moldable and oversized (15 x 20 cm) to ensure it can wrap around standard single-gang, double-gang, and even deep-style plastic or metal junction boxes. You can easily trim or overlap the material to get an airtight seal. Is it safe to use around wires? Yes. The material is non-conductive and designed specifically for use on the exterior of electrical boxes. It is UL Classified and fire-rated for up to 2 hours, meaning it helps prevent the spread of fire and smoke through wall penetrations. Will the adhesive damage paint or wood when I remove itWill the putty dry out or crack over time? No. Our acoustic putty is a non-setting, non-hardening formula. It remains flexible and "tacky" indefinitely, ensuring that as your house shifts or vibrates, the acoustic seal remains airtight without cracking or shrinking. Can I use this on existing walls?Yes. While easiest to install during construction, you can apply these to existing walls by removing the outlet faceplate and carefully molding the putty around the box from the inside or through the drywall gap. Always ensure the power is off before working near exposed wires. Do I need to apply this to both sides of the wall? For the best results, yes. If you have "back-to-back" outlets (outlets in the same wall cavity for two different rooms), noise travels through them like a tunnel. Applying pads to the boxes in both rooms creates a dual-barrier that significantly increases the STC rating of the wall.. Shipping? Ships in 1 business day.
