So you’re looking for ways to soundproof your home? You’ve come to the right place. As house sizes in New Zealand get smaller, one of the questions we are often asked is how do you reduce the noise transfer between walls?
New Zealand has historically been bad for building poor quality homes and while recently standards have improved, in dense urban areas, noise in the home is a big issue for many New Zealanders.
Soundwaves enter your home through windows, doors, floors, ceilings, and walls so your goal when looking at soundproofing your home is to block them out.
There are two main types of noise you want to try and control in your home. The first is preventing exterior noise from entering the home and the second is noise transfer between rooms inside your home. In this article we discuss some ways that you can help soundproof your home, reducing noise transfer.
Adding a second layer of plasterboard is a great way to cut down noise transfer. Most plasterboard companies have specific noise reduction products which made a difference. Researching the right plasterboard options will immensely help soundproof your home and adding two layers of plasterboard to your walls help reduce noise transfer even further particularly for the higher sound frequencies.
Insulation is one of the most powerful tools at your disposal to soundproof your home. While your standard batts will help to some degree, your goal is to really provide dense barrier without gaps.
CosyWall Insulation is a perfect product for this purpose as it’s blown directly into your internal or external wall cavities without having to remove the linings. The dry fiber is blown at such a high density it fills up all the small gaps often left by batts or segments and provides an effective barrier against high and mid-frequency noise transfer between walls.
Flooring also makes a big difference in dampening noise transfer to soundproof your home. Hardwood floors are typically bad at blocking noise, especially when used as part of your mid-floors. Adding a soft flooring product such as vinyl or even newer hybrid planking with a good underlay is one option however your gold standard is carpet. The thicker the carpet and underlay, the better results you’re going to gain in stopping noise transfer.
Like air, the noise will try and get through any gaps in your home so ensuring your windows and doors are sealed well is critical. Windows in older homes aren’t well-sealed so upgrading the joinery and adding double glazed windows will make a significant difference to noise reduction.
Likewise, doors are often hollow in the center so if noise reduction is really important, replacing these with solid doors will also help. It’s also best practice to ensure doors are well sealed and there are specific products from your local hardware store that can help with this.
There are other specialty products and systems that can also make a big impact on noise control. If you’re serious about reducing the noise in your home have a chat with the CosyWall team for an obligation-free assessment today.
