Asbestos encapsulation versus asbestos removal: which is best?

If you find asbestos lurking within your property, it’s important to consult an expert before deciding what to do with it.

Asbestos was a popular building material until it was found to be a dangerous substance and subsequently banned in 1999. It was discovered that fibres of airborne asbestos posed a significant health risk when breathed in.

If you discover asbestos in your property, then it is your responsibility to ensure that it is safely managed.

A couple of options available for managing asbestos include complete removal and encapsulation.

Encapsulation involves covering the asbestos with an impervious material that protects it from damage and prevents any fibres from becoming airborne.

Asbestos removal or encapsulation: which should I choose?

According to the Health and Safety Executive (HSE) any asbestos in your property is safe unless it becomes damaged. Damage can be caused by drilling, sawing, sanding, tearing down, or otherwise disturbing the material so that fibres become airborne.

The right course of action will depend on the condition and extent of the asbestos in your property and a risk assessment should be carried out by an expert prior to any work being carried out.

Advantages of encapsulation

If encapsulation is deemed to be an appropriate course of action, then it has several advantages over removal including:

Can usually be completed quicker than removal.
Causes less disruption.
No need to dispose of hazardous material.
Affordable.
Minimal risk as asbestos is disturbed less.

If you discover asbestos in your property you should never attempt to remove or encapsulate it yourself. The Control of Asbestos Regulations require this work to be carried out by a trained and licensed professional contractor.

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.

Points to Consider When Soundproofing A Historic Listed Building

If you own a listed building then you will be well aware of the constraints this puts on development work and even basic maintenance. Even soundproofing will require a certain degree of planning so as not to alter the character of the building. So how do you best approach insulating and soundproofing your listed building?

The first place to start is a survey of the building. This will give you all the technical details you need so you can plan the project and adhere to building regulations. The survey will also tell you what materials to use.

Once you have gained this information you can then put together a plan of the work you intend to do and submit it in order to get planning consent. This is critically important as anything that alters the character of a listed building or replaces existing materials with materials of inferior quality or that will cause deterioration in other parts of the building will be deemed unsuitable.

If you are not confident of managing this process yourself it is highly advisable to seek expert help even if the soundproofing you are installing will be largely hidden from view.

3 Simple Sound Insulation Ideas

These simple sound proofing ideas will be ideal for most properties and in some cases even for historic listed buildings if you don’t wish to go through the planning permission process.

Acoustic blinds or curtains
If your building is poorly insulated against noise from outside, then acoustic blinds or curtains can go some way to reducing the amount of noise entering rooms. It is important to remember however that insulating your room this way will be good at reducing echoes in a room but only when they are closed which is ok at night but you will need other sound proofing measures for daytime.

Synthetic grass
Fake synthetic grass is popular with gardeners that like the low maintenance aspect of it but it is also being put to use as a form of insulation. Whether it is laid on floors or walls it has proven to be a good soundproofing material if you like your spaces green and natural looking.

Acoustic panels
The beauty of acoustic panels is they are effective at insulating sound coming through walls and they can be decorative. But if your property is listed you may still need planning permission to install them.

Asbestos in a Commercial Property? Here’s What You Need To Know

If you own a commercial property have you ever thought that about asbestos? While asbestos hasn’t been used in construction since way back in 1999 it remains present in many buildings dating back before this period. The penalties for those maintaining a building and ignoring the risks of asbestos exposure are severe as well as the potential consequences for those exposed to fibres so it is worth understanding what needs to be done if there is the risk of asbestos exposure present in your commercial property.

Much of the legislation on asbestos refers to Control of Asbestos Regulations 2012 (CAR 2012) and Asbestos Regulations 2006 (CAR 2006). If you are the landlord and owner of the building, responsibility for dealing with risks posed by asbestos will be in your hands and anyone occupying the building as a commercial tenant must also comply with any action that needs to be taken.

Asbestos becomes dangerous when it is disturbed and dangerous fibres are released. These fibres enter the lungs and cause various cancers and other illnesses. Proper assessment of a building suspected of containing asbestos should include an inspection to see if the material is present, the creation of records and an assessment the condition of the asbestos. Anyone carrying out works must also be notified of its presence.

Removing asbestos is a difficult and expensive tasks due to the risks involved. A cheaper and easier way to deal with asbestos is via encapsulation which essentially seals in the material so that it doesn’t pose a risk.

Tips to Consider When Choosing Insulation

Once you have decided you need insulation for your home or other type of property the next step is to consider which type of insulation is best.

There is certainly no shortage of choice in stores and online making it difficult to decide which way to go. Some types of insulation will be better at absorbing sound while other types offer better thermal properties.

So, if you are having problems deciding on the best material here are some handy tips to help you.

Cost
The cost of insulation will vary widely. Some materials may seem cheap but as we will explore in the next point, the cheapest insulation isn’t always the easiest to install.

Ease of fitting
Insulation can come in a variety of different forms. Most commonly you can buy it in a role but it is also manufactured as solid boards and can come in spray form too. Some types such as spray foam will require specialist equipment and breathing apparatus to install and is usually applied by a professional.

Environmental impact
Often overlooked the environmental impact is an important consideration when choosing insulation. While you will save energy installing insulation it is worth finding out what the impact is to the immediate environment as well as externally.

The Relationship Between Climate and Insulation

Most of us know that insulation is an important part of any building we occupy and increasingly so now that we are being forced to consider how much energy and consequently money we are wasting.

Money is also a factor in the type of insulation people choose for their homes. Often there are attempts to go it alone and do a DIY job to save even more. After all there are plenty of helpful videos available on Internet or advice from friends to teach you. What often cannot easily be gained from watching other people’s experiences is the insulating materials and methods you’ll need for different types of climate.

Climate is one of the key considerations when choosing insulations and depending on where you live in the UK some insulation types can be better than others. If you live in western parts of the UK the climate is often wet and windy for a large part of the year as this part of the country takes the brunt of weather coming from the stormy Atlantic. That said, temperatures don’t usually fluctuate too rapidly.

The east side of the UK can get very cold with temperatures fluctuating wildy at times as the cold North sea often exerts its influence. Weather in the east is also drier than the west.

In the South East, the weather is particularly dry through summer and also warmer with hotter summers.

So if you live in a colder climate keeping out cold will be the priority whereas in the warmer parts of the country keeping out heat while also protecting against the cold will be the priority.

How Long Can You Expect Your Insulation To Last?

Most people will ask about how long things like roof tiles and flooring will last but few people consider insulation. One thing is certain, no matter what insulation you use, it won’t last forever and certain types of insulation are known to last longer than others. So let’s look at the different types of insulation commonly used and compare their lifespans and durability.

Spray foam insulation
Spray foam insulation has increased in popularity due to its excellent durability and ease of application. It is also much better at resisting mold growth and sealing any air leaks than alternative forms of insulation. You can also look forward to low maintenance over its lifetime. The only drawback is that its lifespan is around 80 years but this is a minor one unless you expect to still be around 80 years from so you can still technically say it will last you more than a lifetime.

Fiberglass Insulation
Fibreglass is the type of insulation you will find in most homes. The material is also extremely durable and provides an excellent defence against humidity. It is also cheaper than most alternatives which is why you will still find this type of insulation in most homes. This type of insulation is expected to last 100 years but wear and tear can take its toll and reduce lifespan if it isn’t inspected regularly.

Recycled Paper Insulation
Recycled paper is another excellent choice and the main thing it has going for it is its limited impact on the environment. This type of insulation can last for 100 years although it is less commonly used than other materials such as fibre glass and spray foam.

3 Signs Your Home Isn’t Insulated Properly

Insulating your home is more important today than it has ever been. In the past the only consideration was for the comfort of the occupants but now a home must reach a certain standard for energy efficiency to be let to tenants or receive a fine. So it pays to be aware of these 3 signs of an uninsulated home.

Draughty rooms
Draughts can come from all sorts of places in the home but the most common sources of drafts are windows and around gaps in doors. Replacing windows and doors is the best way to resolve this issue.

Walls, ceilings and floors feel cold to the touch
If lofts are not insulated properly you may be able to tell by touching walls and ceilings and checking to see if they feel cold. If upstairs bedrooms feel cold it could be a sign that radiators are not working as well as they should or the insulation above needs replacing.

Hot in the summer cold in the winter
One of the biggest giveaways of a poorly insulated room is marked fluctuations in temperature. An extreme example is when you have an unheated uninsulated conservatory that is virtually unusable in the winter and on hot summer days. While rooms within the house are unlikely to be as bad as this, you will still notice that temperatures in the room are not as comfortable as other rooms.
