Many New Zealand homes suffer from poor sound transfer between internal walls, ceilings, and floors. If you can hear televisions, footsteps, or conversations from the next room, your property lacks adequate sound barriers. Pilkington Insulation provides a specialist consultation service to diagnose noise path issues across Auckland and Northland. We formulate tailored solutions, providing a complete service from initial thermal and acoustic inspection to full installation. If required, we can even handle post-installation plastering and painting to restore your linings perfectly.
Soundproof Insulation Experts in Auckland & Northland
Intrusive noise can disrupt your sleep, lower your productivity, and compromise your privacy. High-performance acoustic insulation is one of the most effective ways to soundproof your home and block out unwanted airborne or impact noises. Because noise varies with frequency and source, our expert team incorporates multiple advanced layers of specialised acoustic materials. This method achieves the highest possible Sound Transmission Class (STC) rating for your residential or commercial structure.
Our primary high-performance product for controlling noise is blown cellulose fibre insulation. This material possesses incredible natural dampening capabilities. When blown under pressure into existing timber walls or mid-floor cavities, the dense, interwoven fibres instantly reduce airborne sound transmission. The random-direction alignment of the natural fibres, combined with our specialised airtight injection method, eliminates the gaps, cracks, and flank paths that traditional batts often miss. This results in a much quieter, more peaceful home.
If you require advanced noise reduction—such as treating a home studio, a multi-unit rental property, or a home cinema—we can design engineered multi-material systems. Contact our team to arrange an on-site consultation to discuss your specific noise reduction goals so we can provide a detailed, accurate quote.
How to Soundproof a Ceiling or Mid-Floor Cavity
For many homeowners and occupants of multi-level dwellings, noise travelling through a ceiling or mid-floor is the most frustrating soundproofing challenge. This difficult issue stems from two specific architectural and lifestyle factors:
Modern Hard Flooring Choices: Today’s preference for hardwood, polished concrete, laminate, linoleum, and tile flooring provides zero impact dampening. Traditional thick carpet laid over heavy rubber underlay naturally absorbs a massive amount of impact energy. However, hard surfaces bounce sound directly into the sub-structure, making life difficult for anyone living or sleeping directly below.
Concentrated Footfall Energy: Every single footstep concentrates a great deal of kinetic energy into a very small, localised cross-section of the floor structure. This mechanical impact directly vibrates the timber joists. The vibration then radiates cleanly through the gypsum plasterboard ceiling below as loud, booming airborne noise.
The Five Core Principles of Noise Control
To successfully resolve complex ceiling and wall noise transfer problems, a combination of acoustic strategies must be deployed. Depending on your building layout, we design systems utilising these five structural methods:
Absorption: Utilizing dense, high-mass blown cellulose fibre or mineral wool within the open cavities to soak up airborne sound waves and stop them from echoing inside empty walls.
Decoupling: Separating the internal wall or ceiling plasterboard from the structural timber studs using resilient clips or isolation channels. This breaks the direct physical path that structural vibrations travel along.
Adding Mass: Installing high-density materials, such as specialised acoustic plasterboard, heavy mass-loaded vinyl (MLV), or double-lined linings, to make it harder for sound waves to physically move the wall.
Dampening: Applying specialised visco-elastic dampening compounds between layers of drywall to convert vibrational energy into microscopic amounts of heat.
Sealing (Airtightness): Eliminating tiny air gaps around electrical outlets, baseboards, and plumbing penetrations. Because sound travels through air, even a tiny gap can ruin the performance of an otherwise solid wall.
Every home features unique framing, spatial constraints, and distinct structural challenges.
