Types of Attic Insulation in Old Houses

types-of-attic-insulation-in-old-houses

Insulation has become revolutionary. Nowadays, you can insulate your property with practically anything from recycled newspaper, to soy-based foam solutions, in order to keep temperatures consistent all year round.

However if you have recently moved into an older property, with pre-installed insulation, it is important that you understand what your walls and rooftops are layered with. If in the near future your ‘to-do-list’ consists of an attic makeover or a loft renovation, you’ll need to understand what you’re working with.

Take a look below at some types of attic insulation in old houses to help you out!

Types of Attic Insulation in Old Houses

A process where glass fibres are woven and spun in an intricate manner, fibreglass insulation remains one of the most popular types of attic insulation in old houses, despite its poor performance long-term. 

How Does It Work?

Fibreglass works as a barrier by enveloping air inside pockets of fluff, which is why it loses its productivity when suffocated by the weight of heavy items, such as boxes or Christmas decorations.

The Problem with Fibreglass

Fibreglass has a nasty habit of containing a chemical called formaldehyde, which is known to be a cause of respiratory problems. This is due to the micro-fibres that make up its chemical composition.

If, like us installation specialists, you have to handle fibreglass, protection is paramount! This is because silvers of glass, almost the width of a fingernail, can infiltrate your skin and throat.

If you come into regular contact with fibreglass, it can lead to inflammation of the skin – or dermatitis, in medical terms. Of course, fibreglass is no way near as dangerous as asbestos – but it’s irritating all the same.

Mineral wool is formed into boards, batts or blankets – the fibres within mineral wool block both temperature and noise exchange through walls

Mineral Wool Insulation

If the first question that comes to mind is “what on earth is mineral wool” then look no further! This represents another historical choice for types of attic insulation in old houses.

It’s a pre-World War method of insulation which comes in two forms. Rock wool – where molten rock is spun into masses of intertwined fibres that have a similar look as candy floss. The other form is slag wool, where the slag by-product is formed on the surface of molten metal.

How Does It Work?

Mineral wool is formed into boards, batts or blankets – the fibres within mineral wool block both temperature and noise exchange through walls.

It’s also known as loose-fill insulation, due to the light texture of the material.

The Problem with Mineral Wool

Similar to fibreglass, mineral wool can lead to itchy skin and the associated dust particles can irritate your throat and other orifices.

If you have mineral wool insulation, we advise you to follow the similar protocol you would follow when handling fibreglass.

Vermiculite has a dual ability in soaking up water and boasting its power of being fire retardant. This means it can be used to soundproof flooring, or even for fluffing up garden soil – bizarre, right?!

Vermiculite Insulation

Lightweight and shiny – vermiculite insulation is one of the common types of attic insulation in old houses in Canada. However, it’s interesting to know that although it was sold in Canada, the material used in the product was extracted from a mine in Montana, USA.

It was widely reported that the mine had a natural deposit of the dangerous asbestos material, which leads to the vermiculite being contaminated.

Unfortunately, by the time this was realised, the insulation was integrated into many local buildings and establishments; often with fatal consequences.

How Does It Work?

Vermiculite has a dual ability in soaking up water and boasting its power of being fire retardant. This means it can be used to soundproof flooring, or even for fluffing up garden soil – bizarre, right?

Although it is easy to apply, it is considered dangerous for many reasons, as we’ll illustrate below.

The Problem with Vermiculite

If the insulation in your home is vermiculite, it is extremely advisable you limit the period of time you spend exposed to it. If you’re unsure as to whether you have this kind of insulation, if it looks grey and brown in colour and looks like popcorn, its vermiculite.

It would be at this point you ring a professional to remove the material.

If you have vermiculite insulation – don’t touch it! It’s not worth getting involved with the removal of the insulation. It’s actually less harmful to live with the material, than to try to remove it yourself. In most cases, we insist on a professional asbestos removal service, or something similar.

What this means is that spray foam acts as a thermal performance enhancer, meaning more heat is kept within the walls of your home, without escaping through your roof. If you are in a position where your home is of a certain age, we highly recommend spray foam insulation to ensure savings all round!

The Modern Approach – Spray Foam Insulation

Spray foam is far superior when compared to different types of attic insulation in old houses. 

When your trusted installation team are on site, they will combine a mixture of chemicals together, and spray the resulting material onto the area of application.

This mixture causes a chemical reaction to form a foam-like substance that begins to expand rapidly. This expansion process occurs almost instantly, and can reach up to 100 times the original size. This forms a blanket of insulation that spreads across the entire surface of your roof.

The expanding process ensures all cracks and crevices are covered, creating an efficient barrier against heat loss and moisture gain. Moisture can lead to condensation related issues, such as damp and mould build-up.

Like with humans, we say that after the 24 hour timeframe has passed, pets will have the same safety guarantee as the occupants. You should of course prevent your pets from chewing the material, but otherwise they are completely safe

Are There Any Known Dangers of Spray Foam Insulation?

More traditional versions of spray foam insulation have been known to cause harm to human health – especially in places like Canada and North America.

The original creations of this product are no longer the safest spray foam product available. Time has moved on, and, therefore, so have the insulation products on offer!

Home Logic Spray Foam is completely safe to be around. We eradicate any risks with our method of application, where we allow re-entry after 24 hours. After this time has passed, and the spray foam solidifies and expands, it offers no further health risks to the property’s occupants.

Can Spray Foam Insulation Be Toxic to Pets?

Like with humans, we say that after the 24 hour timeframe has passed, pets will have the same safety guarantee as the occupants. You should of course prevent your pets from chewing the material, but otherwise they are completely safe.

This is a distinct advantage over other types of attic insulation in old houses.

A property that is more thermally efficient will no longer need to rely on manual heating systems to maintain an even temperature. Perfect!

Spray Foam Insulation Benefits

Constricted Spaces Not a Problem

One of the main benefits of spray foam insulation is its ability to squeeze itself into spaces where other insulation methods cannot.

As the material is sprayed on, there’s no need to get up close with the area of application. With our high-tech equipment, we can stand at a reasonable distance, and spray away.

Tight spaces need not be an issue because when the foam expands on impact, it will cover all areas, without effecting the performance of the spray foam overall.

Unbeatable Thermal Properties

As mentioned above, spray foam insulation provides unbelievable thermal improvements to your home, leading to a significant reduction in the heat lost from your home. If you feel you are using too much energy, then spray foam insulation is the perfect place to start!

We have done our research, and we believe that very few insulation products provide a similar level of thermal quality as our own Home Logic Spray Foam.
