5 common sources of external noise pollution

Noise pollution occurs when sounds exceed a certain level and become annoying and harmful to health.

Noise pollution is a common problem in today’s busy, built-up, technology-driven society, particularly within big cities.

Noise pollution created by external sources outside of our homes can be particularly difficult to deal with as we have no control over it, leaving us feeling helpless.

As well as being very annoying, studies have found that being exposed to constant noise pollution can be damaging to health too.

Here are five of the commonest sources of external noise pollution here in the UK.

Airports and flight paths– Living close to an airport can expose you to significant harmful noise pollution. Studies have found that the constant loud noise created by aeroplanes taking off and landing can be very damaging to health. There are noise limits and restrictions on night flights in place at many UK airports to protect those living close by from noise pollution.

Busy roads – According to the European Environment Agency,road traffic is the biggest source of noise pollution in Europe, accounting for about 70% of all noise pollution. In the UK there is no legal limit to road noise. Living close to a busy road can mean being subjected to the hum and noise caused by vehicles all day and all night long with no respite.

Industrial sources– Living close by to industrial businesses or factories can mean being subjected to the sounds of a variety of bangs, crashes, clanks, vehicles, and electrical whirring and buzzing.

Noisy neighbours– Neighbours that constantly play loud music can quickly turn into a constant source of stress and annoyance. As well as noise from domestic neighbours, people living close to busy pubs and bars may also experience high levels of noise pollution from music and anti-social behaviour.

Construction work – Although most construction projects are only temporary, more long-term construction sites can cause people living nearby a real headache. Councils can serve notices to those carrying out construction work to reduce noise nuisance for those living and working nearby.

If external noise pollution is disrupting your home life, you could benefit from soundproofing your property.

Here at Metropolitan Insulation we provide a wide range of different soundproofing productsand solutions to suit any requirements. Get in touch with our team of experts for further help and advice by calling us on 0800 028 4042.

4 ways to make your roof more weatherproof

Weatherproof your roof to protect your home’s structure and keep dampness at bay.

Your roof is your home’s first line of defence against the elements. Wind, rain, ice and snow will all batter your roof over the years, so it’s important to take measures to ensure that your roof is as weatherproof as possible.

Taking precautions with your roof will help it to effectively protect your home from the weather and save you money and hassle in the long run.

Here are four ways to get started with weatherproofing your roof.

Maintain gutters

One of the commonest causes of roof leaks and damage is blocked or broken guttering. Your gutters protect your roof by directing water away from it. If your gutter becomes blocked or broken, then it will need immediate attention to stop water from overflowing onto your roof. Regularly inspecting, clearing and cleaning your gutters helps to prevent problems occurring.

Lead flashing

Roof flashing is sheet metal applied to your roof’s joints and edges to seal it and prevent water from leaking in. Flashing plays a very important part in protecting your roof from the rain so it’s important to ensure that it is applied in all the right places and remains in good condition. Flashing comes in a variety of materials including copper, steel and aluminium, but lead flashing is the most durable and long-lasting option.

Repair and maintain tiles

Any cracks or holes in your roof will allow water to seep in, potentially causing expensive damage to your belongings and your property’s structure. Ensure that any cracked or missing tiles are repaired or replaced quickly to avoid further damage occurring. If you feel like damp is regularly making its way into your roof, you may benefit from applying a tile sealer to reinforce your roof and protect from hairline cracks.

Spray foam

Applying spray foam to the underside of your roof is extremely effective at sealing and reinforcing your roof to prevent the ingress of rain, snow and dirt. As well as weatherproofing your roof, spray foam also acts as an excellent thermal insulator, keeping your home warmer and lowering your energy bills.

What is nail sickness and how is it fixed?

If you’re regularly having problems with loose or missing roof tiles, it could be a sign that your roof is suffering with nail sickness.

Nail sickness is a term used to describe the natural deterioration of the nails that hold your roof tiles in place. Over a long period, it is natural for nails to corrode and rust. Unfortunately, if all your roof tiles were attached at the same time you will find that all the nails begin to deteriorate at a similar time too.

Nail sickness is more common in older properties with very old nails, particularly because the nails used in older buildings were generally of a poorer quality than those used today.

If you suspect that your roof may be suffering with nail sickness, it’s important to call in an expert immediately and not leave the problem to worsen. Falling and missing roof tiles are not only a safety hazard, they could also cause significant damage to your property by letting in rain, which will cause damp and structural damage over time.

Repairing a nail sick roof

A professional roofing contractor will be able to inspect the condition of your roof and advise you on the extent of the damage. In some cases, it may only be a small section of the roof that is affected, in which case repairs can be carried out to this section only. Generally, though, nail sickness will affect the entire roof, in which case you have a couple of options for fixing the problem.

Strip and re-slate the roof–Your first option is to have your entire roof replaced by stripping and re-slating it. The price of a new roof will vary depending on several factors including the size of your roof and the materials used, but it is generally an extensive job which can be very expensive.

Apply spray foam to the underside of the roof– An affordable alternative to re-roofing is to have spray foam applied to the underside of your roof. Spray foam will bond your roof tiles to each other and to your roof’s structural timber to cure nail sickness. It also provides your roof with excellent weather-resistance and thermal insulation.

Tips for protecting your roof from pests and vermin

Attic spaces are warm, sheltered, and infrequently disturbed, making them the ideal environment for pests and vermin.

If pests enter your home through your roof, they can multiply and cause significant damage to your roof’s internal structure and items being stored in the loft before you even realise that they’re there.

If you notice any of the following signs that you may have a problem with pests, it’s important to investigate and act swiftly to minimise damage.

Signs that you may have a problem with pests

Droppings
Bad smells
Damage to the roof’s structure
Bite marks or damage to belongings in the loft
Noise

Preventing pests from entering your roof

Birds– Birds roosting or nesting in, on, or around your roof, eaves or chimney can cause a lot of mess with their droppings.

Gel-repellents and spike strips can be applied to the roof to deter pigeons from landing on it.

Rats – If rats enter your home through your roof, they can spread disease, leave droppings, and cause damage to items stored in the loft and to your roof’s structure.

To make it more difficult for rats to gain access to your roof, remove any creeping plants from the walls and cut back any tree branches that overhang your roof. Any gaps or holes in or around your roof should be covered with wire mesh or filled with expanding foam.

Insects– Insects like bees, wasps, moths, and beetles can all find their way into your loft and cause significant damage.

To keep insects out of your roof you need to fill or repair all cracks and holes that they could gain entry through.

Protecting your roof from pests using spray foam

A simple way of sealing your roof to prevent pests and vermin from entering is to have spray foamapplied to the underside of your roof. Spray foam bonds slates and tiles to each other and to your roof’s structural timber to effectively seal all routes of entry.

As well as protecting from pests and strengthening your roof, spray foam is also an excellent source of insulation and soundproofing.

Can insulation cause condensation?

An insulated building is comfortable and energy efficient. But can making your building warm and air tight cause condensation problems?

To answer this question, it’s important to first understand how condensation is formed.

Warm air can hold more moisture than cold air, and condensation occurs when warm water vapour in the air meets a cold surface. This is because as the water vapour cools down, it condenses back into liquid form.

So, in theory, the warmer your home is, the better the conditions are for condensation to occur.

However, it’s not solely the insulation that causes condensation, in fact, lack of insulation can also be a factor that causes condensation. It’s several factors, that when combined, create the right conditions for condensation to form.

Consider the two key factors below before getting your home insulated to help prevent condensation problems.

Lack of ventilation

The number one factor to consider before installing insulation is whether your home has enough ventilation. Ventilation allows water vapour to escape from the building, and condensation to quickly evaporate. From air vents to extractor fans, condensation is less likely to occur in a home that is well ventilated.

Type of insulation

If you decide to insulate your home, make sure you’re well informed about what type of insulation is suitable for its structure and climate.

There are now plenty of types of insulation available to choose from, breathable or water vapour resistant options can be effective at preventing condensation.

At Metropolitan Insulation, our spray-applied insulation foamseals your roof to prevent air leakage and keep your home warm. Our foam is water vapour resistant and is installed at rafter level to prevent condensation build up.

Difference between surface & interstitial condensation?

Condensation is an annoying and potentially damaging household problem that most homeowners will encounter at some point.

Signs of condensation include water droplets on windows and walls, damp patches, and mould. Condensation can look unsightly, cause damage to your home, and create unhealthy living conditions.

How is condensation formed?

Condensation is caused when warm water vapour in the air hits a cold surface. The cold surface cools the water vapour to a temperature that is below its condensing point, turning it from a gas back to a liquid.

Interstitial condensation versus surface condensation

There are two different types of condensation, interstitial and surface. The main difference between the two is where they occur.

Whilst surface condensation appears on the surface where it is visible, interstitial condensation occurs inside the layers of your building’s walls, roof or floor where it cannot be seen.

Of the two, interstitial condensation is usually the more damaging problem. As this type of condensation occurs within your building’s fabric, it may have caused considerable deterioration of your building’s internal elements before you notice the signs that there is a problem.

Top tips for banishing condensation

A few simple ways to reduce levels of condensation in the home include:

Open vents, windows or doors when steam from washing or cooking is present.
Keep the temperature in your home consistent.
Ensure your home has adequate ventilation.
Ensure your home has adequate insulation.
Insulate your home using a water vapour resistant material like our spray-applied polyurethane foam.
