The Remarkable Benefits of Spray Foam Insulation

When it comes to insulating your home, spray foam insulation is a game-changer. Unlike traditional insulation methods, spray foam offers unique advantages that can significantly enhance energy efficiency, indoor comfort, and overall building performance. In this blog, we will explore the remarkable benefits of spray foam insulation and why it’s worth considering for your home.

Superior Insulating Properties:

Spray foam insulation is renowned for its exceptional insulating properties. When applied, the foam expands and fills every crack, crevice, and void, creating a seamless and airtight barrier. This comprehensive coverage ensures that no gaps are left exposed, reducing heat transfer and preventing drafts. With its high R-value (a measure of thermal resistance), spray foam insulation provides excellent insulation, keeping your home warm in winter and cool in summer.

Energy Efficiency and Cost Savings:

One of the most significant advantages of spray foam insulation is its ability to maximise energy efficiency and lead to substantial cost savings. By forming an effective thermal barrier, it minimises heat loss or gain, significantly reducing the energy required for heating and cooling. This reduced energy consumption translates into lower utility bills and long-term savings. Over time, the cost savings can often offset the initial investment in spray foam insulation.

Air Sealing and Moisture Control:

Unlike other insulation materials, spray foam not only insulates but also acts as a comprehensive air sealant. It seals off any cracks or gaps in your building envelope, preventing air infiltration and exfiltration. This airtight seal is essential for blocking drafts, minimising energy loss, and maintaining a consistent indoor temperature. Additionally, spray foam insulation helps control moisture by repelling water and preventing condensation, reducing the risk of mold and mildew growth.

Sound Dampening:

In addition to its thermal properties, spray foam insulation also provides excellent sound dampening capabilities. The foam’s dense structure absorbs sound waves, reducing noise transmission between rooms and from the outside. Whether you live in a busy urban area or have noisy neighbors, spray foam insulation can create a quieter and more peaceful indoor environment.

Longevity and Durability:

Spray foam insulation is known for its longevity and durability. Once applied, it can last for decades without losing its insulating properties or degrading over time. Unlike other insulation materials that may settle or sag, spray foam retains its shape and effectiveness, providing long-term performance and value for your home.

Environmentally Friendly:

Spray foam insulation is an environmentally friendly choice. It helps reduce energy consumption, lowering greenhouse gas emissions and minimising your carbon footprint. Additionally, some spray foam formulations use eco-friendly, water-blown agents that have reduced environmental impact. By choosing spray foam insulation, you contribute to a more sustainable future.

Spray foam insulation offers a range of remarkable benefits that go beyond traditional insulation materials. Its superior insulating properties, energy efficiency, air sealing capabilities, moisture control, sound dampening, durability, and environmental friendliness make it a smart investment for homeowners. By choosing spray foam insulation, you can create a more comfortable, energy-efficient, and environmentally responsible home. Consider this innovative insulation solution and unlock the incredible advantages it brings.

It is applied as a liquid and expands into a foam, creating a seamless and airtight barrier. Here are some key benefits of spray foam insulation:

Superior insulation performance: Spray foam insulation provides exceptional thermal insulation properties, effectively sealing gaps, cracks, and voids. It forms a continuous and airtight barrier that minimises heat transfer, resulting in significant energy savings and improved energy efficiency. It outperforms other traditional insulation materials, such as fiberglass or cellulose, in terms of R-value, which measures thermal resistance.
Air leakage prevention: One of the major advantages of spray foam insulation is its ability to seal even the smallest gaps and cracks in walls, floors, and ceilings. This prevents air leakage, which can account for a significant amount of energy loss in buildings. By creating an airtight envelope, spray foam insulation helps to maintain consistent indoor temperatures, reduces drafts, and enhances overall comfort.
Moisture control: Spray foam insulation acts as a moisture barrier, preventing the infiltration of water vapor. It resists moisture absorption and helps to control humidity levels within a building. By reducing the risk of condensation and moisture-related issues, such as mold growth and structural damage, spray foam insulation contributes to a healthier and more durable indoor environment.
Sound insulation: Spray foam insulation also provides excellent soundproofing properties. Its dense and closed-cell structure absorbs sound waves, reducing noise transmission between rooms and from external sources. This can significantly improve the acoustic comfort within a building, making it quieter and more conducive to work, rest, or relaxation.
Versatility and adaptability: Spray foam insulation can be applied to various surfaces, including walls, roofs, floors, and crawl spaces. It conforms to irregular shapes and contours, filling in gaps and ensuring a complete insulation coverage. This versatility allows for customised and precise installation, making spray foam insulation suitable for both new construction and retrofit projects.
Long-lasting performance: Spray foam insulation is known for its durability and long lifespan. Once applied, it remains stable and does not settle or deteriorate over time. This means that the insulation’s performance and effectiveness will last for many years, providing ongoing energy savings and benefits without the need for frequent replacements or maintenance.

In summary, spray foam insulation offers superior insulation performance, air leakage prevention, moisture control, sound insulation, versatility, and long-lasting performance. Its ability to create an airtight and seamless barrier makes it a highly efficient and effective insulation solution for both residential and commercial buildings. By choosing spray foam insulation, property owners can enjoy energy savings, improved comfort, enhanced indoor air quality, and a more sustainable and durable building envelope.

Should I Insulate my Loft?

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.

Loft insulation is effective for at least 40 years and it should pay for itself many times over.

Choosing loft insulation

If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate – and in most cases, it is possible to do it yourself.

If access is easy and your loft joists are regular, you can use rolls of mineral wool insulation. The first layer is laid between the joists – the horizontal beams that make up the floor of the loft – then another layer is laid at right angles to cover the joists and make the insulation up to the required depth.

Here’s what to consider when installing loft insulation:

1. Storage space

If you plan to use the loft or attic for storage, you will want to lay boards over the joists. Unfortunately, if you only insulate between the joists before doing this, the insulation won’t be thick enough.

To get enough insulation, you can raise the level of the floor so you can fit enough mineral wool beneath the new floor level. You can do this by fitting timber battens across the joists, or you can buy purpose-built plastic legs that fit on the joists and support the new floor. It’s important to leave a ventilated air gap between the insulation and the boards to prevent condensation on the underside of the boards.

Make sure you don’t squash the mineral wool when you fit the boards on top as this this will reduce its insulation value.

2. Warm loft

An alternative way to insulate your loft is to fit the insulation between and over the rafters – these are the sloping timbers that make up the roof itself. You can use rigid insulation board, carefully cut to size, or you can have foam insulation sprayed between the rafters.

Whichever approach you use, you will need a specialist professional to insulate your roof – this is not a DIY job.

Advantages:

The roof space will be warmer than with standard loft insulation, so you won’t need to worry so much about freezing tanks and pipes.
You can board the floor for storage without having to raise it to create extra depth.

Disadvantages:

Insulating at rafter level is considerably more expensive than most standard loft insulation.
As well as insulating the roof, you will have to insulate any gable walls, party walls and chimneys in the loft space. If you leave these uninsulated, then the heat will bypass your new insulation making it largely ineffective.

3. Inaccessible loft spaces

If your loft is hard to access, you can have blown insulation installed by a professional, who will use specialist equipment to blow appropriate insulation material into any awkward space. They may use mineral wool fibre, treated cellulose or polyurethane foam.

Soundproof Foam VS Acoustic Foam

The misconception about foam being soundproof exists mostly because people lack the understanding of the differences between sound absorption and soundproofing.

It is natural to assume that if products like foam absorb sound, there will be none that is left to escape the room.

Unfortunately, sound is not like a fluid that gets absorbed and trapped in something like a sponge. The way sound behaves needs to be understood clearly here.

Sound waves are nothing but vibrations and when they strike a surface, they tend to vibrate it.

Sound does not ‘pass’ through a wall or ceiling but merely vibrates it. These vibrations are further transferred to the other side and that is how sound transfer takes place through walls, ceilings, and other surfaces.

1. Walls and Ceilings

The most common myth is that panels made of foam can be stuck on walls and will reduce the amount of sound from entering or leaving a room.

The foam that you see stuck on the walls of studios is not meant for soundproofing but is meant for sound absorption. The products that do the actual soundproofing in a studio are something else.

What You Should Be Doing Instead

You should first of all try to make your walls heavier. You can add mass to your wall by:-

Extra Drywall

Installing an additional layer or two of drywall will help to reduce sound transfer. A 5/8” thick drywall sheet weighs 2.31 pounds per square foot. That’s some serious mass and is a great substance for reducing sound transfer.

Coming back to foam, there are many varieties available and their densities vary depending on the type and grade. However, the foam would have to be several inches thick to match the mass of drywall.

Pros

Low cost.
Lots of mass.

Cons

Effort and workmanship required to install.
Involves modification of structures, so not an option for rented apartments.

Floors

Impact Noise
Airborne Noise

Impact noise is the noise caused as a result of footsteps or furniture being moved on the floor.

Airborne noise is the sound that is normally transmitted through the air and these include traffic noise, dog barking, neighbors yelling, and everything else.

Benefits of spray foam insulation for historic or listed buildings

Spray foam insulation is an ideal solution for securing tiles on the roofs of listed and historic buildings.

Spray foam insulation is applied to the underside of roofs to bond slates and tiles together, providing effective insulation and structural support.

Whilst spray foam insulation can benefit buildings of all different shapes, sizes and ages, it can be particularly useful for securing tiles on the roofs of historic or listed buildings, here’s why:

Preserve appearance

It is very important to preserve the appearance and original character of historic and listed buildings by retaining original features and materials where possible. Securing and sealing the existing roof with spray foam can help to bond the existing roof and tiles together to cure nail fatigue and avoid the need to replace roofing materials.

Protect roof tiles against theft

Very old and listed buildings are also more likely to have valuable tiles on their roofs, including lead tiles, which are frequently targeted by thieves.

Bonding your roof’s tiles together and to the roof’s structure using spray foam will help to protect valuable roof tiles from being stolen.

Further benefits of spray foam insulation

As well as protecting and preserving the outer appearance of historic and listed buildings, spray foam insulation provides a whole host of other benefits including:

Affordable solution to re-roofing.
Makes the roof weather-resistant.
Seals the roof to get rid of air leaks and draughts.
Improves the building’s energy efficiency.
Keeps the building feeling warm and comfortable.
Prevents condensation build-up.
Reduces the risk of pipes and tanks freezing.

The spray foam we install at Metropolitan Insulation prevents interstitial condensation, whilst also allowing the roof’s battens to ‘breathe’. It also meets Class 1 Surface Spread of Flame when tested to BS 476 Part 7:1997.

Noisy household appliances and how to stop them being a nuisance

You may be used to the familiar sounds of your household appliances whirring, buzzing and humming, but have you considered how the noise pollution in your home could be affecting your health?

According to the World Health Organisation, being exposed to noise that exceeds 55db can disturb sleep and cause stress, having a negative effect on health and wellbeing.

Other more serious illnesses that have been linked to exposure to high noise levels include heart disease, hearing problems, high blood pressure, stroke, and type 2 diabetes.

Whilst we may quickly find excessive noise from our neighbours or traffic outside extremely irritating, many of us accept and put up with the noise made by our household appliances.

Some of the noisiest appliances in our homes include:

Hairdryers
Vacuum cleaners
Food processors
Washing machines
Dishwashers
Air conditioning
Extractor fans
Refrigerators
Lawnmowers

If you have appliances in your home that make an excessive noise, there are steps you can take to try to minimise the effect they have on your health and wellbeing.

Close doors

Unless you have a home with an open plan design, simply remembering to close doors whilst very noisy appliances are being used can help to reduce the level of noise you and your family are being subjected to.

Replace noisy appliances with low noise Quiet Mark appliances

Quiet Mark is an international mark of approval given to certain low noise appliances by the UK’s Noise Abatement Society.

Areas Where You Can Use Spray Foam Insulation In Your Home

When most people think of insulation, they think of either loft or cavity wall insulation but there may be other spaces in the home or office that could benefit from spray foam insulation. Besides the loft, here are some other areas that can benefit from spray foam insulation.

Use spray foam insulation in cinema and media rooms
If you have a home cinema or media room then may want that room insulated to ensure sound doesn’t escape and disturb the rest of the household. Spray foam is perfect for this purpose because it disrupts the transmission sound. Depending on where the room is in the house it will also make it more energy efficient.

You can use spray foam in a crawlspace
Not every home will have a crawlspace but you may find them in some blocks of apartments and offices. Adding spray foam to your crawlspace means you will reduce the build up of moisture around heating and cooling systems which will help improve air quality.

Extensions
If you are building an extension, spray foam can help here too by ensuing the correct balance of insulation with the rest of the house.
If you are looking to get your home insulated, why not give us a call for an inspection and a quote?
