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.

Is Your Insulation Fire Rated?

You may be starting a new insulation project or considering replacing the insulation you have as the cold winter months set in but have you thought about the fire resistance of the material you’re using? Before fitting insulation, it is important to consider how it might behave in a fire to ensure you are making the best choice and don’t end up with a material that catches fire easily or readily emits toxic smoke. With this in mind here are the most common insulation types together with information on how resistant they are to fire.

Rockwool
Mineral is regarded as one of the best materials when it comes to fire resistance. It is able to withstand heat more than 700 ºF above that of the average home fire.

Spray Foam
Many people assume spray foam to be flammable but it actually contains fire retardants. The material also fills air gaps more effectively than other insulation types cutting off the air that is a major ingredient allowing fires to spread.

Foam Board
Foam board might be cheap and readily available but it certainly isn’t a good performer when it is subjected to heat from fires. Add to this the toxic fumes you get when it burns and you may need to reconsider installing it

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.

Why Consider Asbestos Encapsulation?

The dangers of asbestos are well known, yet there are still many buildings in the UK that have some of this potentially deadly material which lies hidden in roof spaces in particular. Worse still, the material is often found in schools and other public buildings, particularly those built between the 1950s to 1980s.

While asbestos that remains undamaged and in good condition is often left in place, there is always the outside risk that it could be disturbed and emit particles that can cause all sorts of lung diseases from lung cancer to asbestosis, diffuse pleural thickening, and mesothelioma. This is why it was made illegal to use the material in construction in 1999.

If asbestos is present in a building, its removal is governed by strict regulations due to the considerable health risks. If these guidelines are not adhered to and lives are put at risk, this can result in hefty penalties including jail terms for those involved.

One way to avoid damage to asbestos and the associated risks is to use a process called encapsulation, which as the name suggests involves coating the asbestos. This prevents any disturbance which might damage the asbestos.

It is also cost effective in reducing the amount of down time and the associated costs of safe removal of the material.

Asbestos Encapsulation Methods

If you have a building which contains asbestos and you want to deal with the problem before any damage occurs which might result in fibres escaping into the air, then one method is to use encapsulation.

Encapsulation acts as a seal to prevent asbestos fibres escaping and can be a cost effective and safer alternative to removing the material altogether.

The encapsulation process involves applying a thick material which resembles paint being sprayed onto the asbestos, which then dries and hardens over the material to prevent any of the harmful fibres escaping.

There are two types of encapsulation, one called ‘bridging’ and the other ‘penetrating’. Bridging acts as a protective coating over the asbestos while penetrating as the name suggests, penetrates into the material before hardening and sealing it.

Encapsulant must be sprayed onto the asbestos with a low pressure spray and care must be taken to remove any damaged or loose asbestos before the chemical is applied. As the process involves working with asbestos, there is still the danger that the person applying the encapsulant material can be exposed to fibres, so it is essential to wear protective clothing including a suit and a respirator.

UK ‘must insulate millions of homes’

More than one home every minute will need to be refurbished in the UK between now and 2050, experts say.

The authors of a report to Parliament say 25 million existing homes will not meet the insulation standards required by mid-century.

The UK needs to cut carbon emissions by 80% by then – and a third of those emissions come from heating draughty buildings.

The government said it would devise policies as soon as possible.

But critics say ministers have been far too slow to impose a national programme of home renovation which would save on bills and improve people’s health, comfort and happiness. It would also create thousands of jobs.

Successive governments have been criticised for failing to tackle the UK’s poor housing stock – some of the worst in Europe.

Local authorities have limited cash to insulate council homes, and landlords and owner-occupiers have proved reluctant to invest large sums in disruptive improvements that will save on bills, but take many years to pay off.

The report from a group of leading construction firms – the Green Building Council – says four out of five homes that will be occupied in 2050 have already been built.

That means 25 million homes need refurbishing to the highest standards by 2050 – at a rate of 1.4 homes every minute.

Who pays?
The authors say this huge challenge also offers an unmissable opportunity under the government’s infrastructure agenda. The fiddly business of insulating roofs, walls and floors creates more jobs and has more benefits than any existing infrastructure priority, they maintain.

The question is how to pay. The government’s Green Deal scheme for owner-occupiers collapsed amid a welter of criticism that interest rates for insulation were too high, and that the insulation itself was too much hassle.

It says the construction industry needs certainty about what it is expected to deliver, and measurement to discover what is already being built. This should stimulate innovation, it says.

Julie Hirigoyen, head of the GBC, told BBC News there was a great prize to be grasped in upgrading building stock: “People will have warmer homes and lower bills; they will live longer, happier lives; we will be able to address climate change and carbon emissions.

“We will also be creating many thousands of jobs and exporting our best skills in innovation.

“Driving up demand for retro-fitting homes is essential for any policy to be a success – the Green Deal told us just offering financial incentives isn’t necessarily the only solution. We need to make it all easy, attractive and affordable.

“The good thing is that the business community is really starting to recognise the opportunity.”

How To Soundproof Doors

You may have a well-insulated home or office, but sometimes noise from outside is the problem and this can often be due to doors not having adequate sound insulation. Here’s how to fix the problem.

Soundproofing doors will have the additional benefit of improving insulation against draughts and it will also provide extra security besides providing sound insulation, so it is definitely worth investing in.

Soundproofing measures for doors should include draughtproofing to exterior doors as standard and if it’s a porch, install secondary double glazing. You can even install toughened glass which will contribute towards both sound insulation and security. When sound proofing doors, don’t forget to fill joints around the doors with acoustic sealant.

Sometimes noise can come from internal doors. In offices and apartment blocks noise will often be heard coming from corridors and so on so in these cases you will find similar benefits from draughtproofing.

Replacing old or lightweight hollow core doors with heavyweight solid core doors is also an option. These will help disrupt the transmission of noise between neighbouring flats for example.

If you are looking for advice and or help on soundproofing your home of office our experts are always happy to help.

Tips For A More Peaceful 2017

Christmas is coming, which means lots of time for celebration and the noise that comes with it. While noise is unlikely to be a problem when we’re all celebrating, when the new year comes, the emphasis usually turns to enjoying a bit of peace and quiet, but what if this peace is interrupted by noisy neighbours or family members? Here are some solutions to consider.

Before moving into the solutions to noise problems let’s explain what causes it.

Sound comes from vibration and this vibration then travels through your home or place of work to varying degrees, depending on how well a building is insulated. So sound has to make its way not only through floors but also subfloors, joists, walls and so on to finally reach your ears as noise.

This why when people jump up and down upstairs, noise levels can become acute and very annoying if it’s coming from people you have no control over like the neighbours.

If it’s coming from your own home you can either stop people jumping up and down upstairs, lay carpet and add cork tiles to walls which should at least help to muffle sound.

If you want to go a step further in reducing noise from say the neighbours then the key is to create a gap within walls and ceilings using additional panels for walls special glues which create the separation in ceilings. If you would like to find out more about how we can help insulate your home better against noise please get in touch.
