Soundproofing Spray Foam Insulation

soundproofing spray foam insulation

Although noise is part of everyday life, if it intrudes on your daily routines, it can leave you feeling frustrated, frazzled and frantically seeking a solution.

From noisy neighbours, to barking dogs, such sounds can surface at any hour, leaving your sleeping routines in flux; far from ideal if you’re a shift worker, or work from home during the day.

Standard building structures offer very little in the way of soundproofing-particularly if they were built before 1930s, when little thought was given to the importance of synchronised systems design.

Heard of cavity walls? Their lightweight structure, and the air-filled gap within them works as a sound transmitter. Instead of isolating you from what’s occurring on the other side of the wall, it will ensure you hear the noise much more clearly. Not good at all.

What Are the Three Main Types of Sound Pollution?

Noise Niggle No.1: Flanking Sound

Flanking sound, however, is a little harder to tackle. It encompasses the wide range of noises within your interior walls, including: pipes, plumbing and wiring.

With the best will in the world, accessing the inside of your walls is far from easy, and to effectively combat this challenge, you need to use an insulation material which will fill every discernible crack and crevice.

Thankfully, Soundproofing Spray Foam Insulation is perfect for these hard-to-reach places. Although initially a liquid, on impact, it expands up to 100 times its original size to provide a superior seal, adhering to all the adjoining components in your construction to virtually eliminate all leaks.

The result? Radically reducing flanking sound from your walls-and an improved STC rating as well.

The best way to combat the airborne sound pollution is to control the movement of air, and prevent it from penetrating the interior; something which spray foam is easily able to do

Noise Niggle No.2: Airborne Sound

This noise niggle refers to sound caused by either interior or exterior factors, including: conversations, telephones, traffic from vehicles and family members who snore!

The best way to combat these disruptions is to control the movement of air and prevent it from penetrating the interior; something which spray foam is easily able to do.

Noise Niggle No.3: Impact and Structural Sound

Impact and structural noise pollution comes from adverse weather conditions, such as fierce winds, taking their toll on the building envelope of your house.

Unlike flanking and airborne sound, impact noises cannot be dampened effectively through insulation alone; the floor must be isolated from the rest of the structure in order to achieve the desired result.

From adhesive foam insulation tiles, to quilted fibreglass curtains, the range of soundproofing materials available is truly staggering!

What Are The Top 5 Soundproofing Insulation Materials on The Market Today?

Soundproofing Solution No.1: Adhesive Foam Insulation Tiles

For smaller amounts of sound transmission, such as the noise from a child’s bedroom, adhesive foam insulation tiles can work wonders.

However, the majority of homeowners have to contend with far greater intrusive sounds, and, as such, require a more substantial soundproofing solution.

Soundproofing Solution No.2: Quietfloor

A quick and easy way to reduce any sound that travels through floors, Quietfloor has been designed with apartments in mind, where the noise from neighbours walking around upstairs can play havoc with your peace of mind.

Application wise, it is suitable for use underneath carpets, laminate flooring and manufactured wood flooring as well.

Soundproofing Solution No.3: Soundproof Curtains

Comprising of quilted fibreglass or rockwool insulation, soundproof curtains certainly play their part in negating noise transmission.

However, in terms of their soundproofing potential, they’re far from a standalone measure; you’ll need to combine them with a variety of other DIY soundproofing products to achieve an effective result.

Although a price-friendly option, soundproofing paint's ability to block out all types of sound leaves a lot to be desired!

Soundproofing Solution No.4: Soundproof Paint

For hardcore DIYers, soundproof paint is a viable option-although it’s not without its critics. 

Yet as technology has evolved, so has this paint itself, and it is now one of the most popular options on offer for those seeking to muffle all kinds of sounds-without blowing their budget in the process.

Unfortunately, the old saying ‘you get what you pay for’ proves true in respect of this paint; at around 30 thousandths of an inch thick, its ability to block out sound has its limits!

Soundproofing Solution No.5: Icynene Spray Foam Insulation

We’re saved the best till last!  In terms of soundproofing properties, Icynene is pretty much unrivalled, reducing noise in residential and commercial properties alike.

This thoroughly modern material virtually eliminates all types of sound. By creating a superior, airtight seal, this product prevents the passage of sound, creating quieter conditions inside.

On application, Icynene will expand up to 100 times its original size, sealing every crack and crevice of your home to provide a buffer between your long-suffering ears, and the source of the sound

How Does Soundproofing Spray Foam Insulation Work?

Delivering superior levels of soundproofing, our open-celled spray foam formula has been designed to prevent both airborne sound transmission, and noises from the walls within.

To achieve this, the product is applied in either the roof, floors or partition walls of your home, by drilling small holes, and injecting the foam inside.

On application, Icynene will expand up to 100 times its original size, sealing every crack and crevice of your home, providing a ‘buffer’ between your long-suffering ears, and the source of the sound.

Which Is Best for Soundproofing-Open or Closed Cell Foam?

In terms of soundproofing spray foam, there are two main types available: open and closed cell foam.

Generally speaking, the former is used in residential applications, where moisture breathability is a fundamental requirement of the build.

Although the latter is more effective for noise reduction (due to its denser composition), open celled spray foam is also a viable option, and is considerably cheaper too.

The H2 Foam Lite version of Icynene our installers use also carries BBA accreditation, making it suitable for soundproofing both old homes and new builds alike.

To get an accurate quote for your property, a free site survey is advised. This will also help you determine whether you need to budget for any additional repair work, and, if so, how much this is likely to cost

Is Soundproofing Spray Foam Expensive?

When you factor longevity into the equation, as well as the yearly savings on your bills, it's clear to see that spray foam offers the best value for money long-term. 

In terms of cost, the National Insulation Association suggests a rough guide price for spray foam of between £20-£50 per square metre on average, although this is obviously relative.

Are There Any Soundproofing Regulations I Need to Know About?

Yes. In 2003, the UK Government passed a document entitled the ‘Approved Document E.’

The document covers the resistance to the passage of sound of various building and insulation materials. 

It was drafted in and approved to ensure that a minimum standard of acoustic separation is achieved within new build designs, to minimise noise niggles between neighbours.

Part E applies to every new build property, with the same stipulations also applying to properties that are divided into flats.

Set your soundproofing spray foam insulation project up for success from the outset by hiring a BBA approved licensed contractor!

How Can I Set My Soundproofing Project Up for Success?

By enlisting the help of the experts. Yes-it really is that simple! Although tempting, D.IY. spray foam projects often end in disaster-with professional installers having to pick up the pieces of a botched D.I.Y attempt!

Icynene installation is very much an exacting science, and, therefore, requires the requisite expertise that only comes through years of thorough training in both the nuances of the product itself, and the correct techniques to apply it.

With the above in mind, here’s 2 top tips to set your soundproofing project up for success:

Top Tip No.1: Grill Your Chosen Contractor

A credible contractor will be more than happy to answer all your questions and offer advice on all aspects of spray foam insulation.

They should also be able to provide you with pictures of previous projects, so that you can get a better grasp of the company, and the overall standard of their work.

Top Tip No.2: Take Additional Steps to Preserve the Peace

Although spray foam is a standalone method of soundproofing, you can easily make a few extra changes to guarantee the best result.

If you live on a busy main road, consider triple glazing your windows. The additional layer of glass provides better sound insulation-and will improve your EPC rating as well. Result!
