Insulation Perth prevents heat from passing through walls and ceilings and helps to keep the house cooler in summer and warmer in winter. It is a cost-effective option that can often be paid back in energy savings within a year.

There are different types of insulation available, depending on the climate zone and design requirements. Some insulation materials repel moisture while others absorb it.

Cellulose is an environmentally friendly, dense insulation material made from recycled paper. It can be blown as loose-fill insulation in attic spaces or as a dense-packed insulant for walls and cathedral ceilings. It is also an excellent soundproofing option. It is a good choice for older homes, as it can fit around obstructions like wires and pipes. The density of cellulose means that it prevents air flow and provides good resistance to both heat and cold.

It is treated with non-hazardous chemicals (such as boric acid, ammonium sulfate and borax) that work as flame retardants and also protect against mold, pests and moisture. It has a high R-Value and is very efficient, preventing both energy loss and excessive condensation. However, it does not provide the same level of air resistance as spray foam or fiberglass.

While it is very effective, cellulose does require a professional installation. It creates significant dust during installation and is chemically treated, so installers must wear masks and gloves. It is also a little more expensive than fiberglass, but it is much more effective, protecting against both heat and cold.

Unlike fiberglass, which can release small glass fibers that may irritate skin, cellulose is soft to the touch and contains no glass fibers. However, it is important to note that if the attic space is not properly ventilated, water and moisture can be trapped inside the insulation, which can damage the structure and lead to mould growth.

Blown-in cellulose is a popular way of insulating new and existing homes. The installers use a blower to fluff up the cellulose and distribute it evenly in attic spaces, between floors or behind walls. They review the finished product, ensuring that all holes are filled and that there are no air pockets in the wall or attic space that could reduce efficiency. In new construction, cellulose can be damp-sprayed or installed dry behind netting stapled over building cavities. When damp sprayed, the insulation is sprayed with a low amount of moisture at the nozzle tip, which activates natural starches within the material and causes it to adhere to the cavity.

Polyurethane

Polyurethane is a versatile and resilient type of plastic that is used in numerous products in daily life. It’s made from a chemical reaction between different ingredients such as isocyanates, polyols and blowing agents, creating a wide range of flexible or rigid foams, elastomers and coatings. It’s also used in a variety of applications including insulation, foam packaging, automobile components and building materials.

Polyurethane insulation systems form a barrier around buildings and homes, helping to prevent air infiltration that decreases energy efficiency and bringing in pollutants, dust and moisture. These systems are typically installed in the attic, walls and foundation of a building, providing an energy-efficient barrier that’s resistant to abrasion, moisture and UV radiation.

There are several types of polyurethane, but the most commonly used in construction is sprayed polyurethane foam. This is a flexible and durable foam that can be shaped to fit the specific needs of the application. It’s also available in a variety of thicknesses, densities and colours.

These polyurethanes are designed to bind different materials together and provide strength, durability and elasticity. These binders can be used to strengthen different construction materials like wood panels, flooring materials and sand casts. They can also be bonded to different construction materials like concrete, masonry and bricks.

Polyurethane elastomers are widely used in the construction industry to increase the longevity and performance of various materials. These rubber-like polyurethanes are highly versatile and offer flexibility, durability and exceptional resistance to chemicals, abrasion and weathering. They’re often used in the manufacture of gaskets, seals and hoses to improve their longevity and durability. Additionally, they’re frequently used as coatings for surfaces to protect them from moisture, UV radiation and abrasion.

Polystyrene

Polystyrene insulation is a common type of insulation in homes. It is a cost-effective material that offers good thermal insulation. It is also moisture resistant and durable. It is made from the chemical styrene and has several forms, including expanded polystyrene (EPS) and extruded polystyrene (XPS).

EPS and XPS are both types of foam insulation materials. They are produced using a process called “polymerization.” Styrene monomers are linked together in long chains to form the polystyrene plastic. This plastic can be molded to create many different types of products. For example, it is used to make disposable drinking cups, trays, and fast-food containers. It is also commonly used for cushioning and packaging items.

Expanded polystyrene is one of the most popular insulating materials. Its low price and ease of installation make it a great choice for homeowners. It is available in many forms, from blocks to styrofoam sheets. It can be installed in walls, ceilings, and floors. Polystyrene is durable and can withstand high temperatures. It also does not melt when exposed to flames.

Like other types of insulation, polystyrene works on the same principle of trapping air pockets. This makes it a good insulator because air is a poor conductor of heat. The insulating properties of polystyrene are further enhanced by its dense structure and moisture resistance.

Although it does not hold the top spot for thermal efficiency, polystyrene is still a strong contender when it comes to home insulation. It has a higher R-value per inch of thickness than EPS, and its density is more effective than other types of foam. It is also moisture resistant, with a water vapor permeance of less than 1.5 perms.

Fibreglass

A traditional insulating material used in homes for over 50 years, fiberglass is available as blanket form (called batts) or as loose fill that can be blown into wall and floor cavities or attic spaces. Generally pink, yellow or white in colour, this insulation has a soft and spongy feel and it can reduce energy bills by slowing the transfer of heat.

Fibreglass is made from recycled glass materials that are melted at high temperatures and then spun into long fibres which are joined together and then baked in an oven to bind them. The fine, spongy fibres create a network of small pockets of air that insulates the home. This air barrier slows the movement of heat from the inside to the outside of the house during winter and vice versa in summer. It also performs well as a sound insulator when fitted correctly.

It’s important to note that when installing fibreglass, it’s imperative to ensure the batts or rolls aren’t compressed or left with gaps as this can reduce their effectiveness. It’s also a good idea to use caulking or foam sealant to close up any cracks or gaps in the building envelope before adding insulation.

Like all forms of insulation, it’s important that fibreglass batts and rolls aren’t exposed to water or moisture. This is because the fine fibres rely on their microscopic air pockets to resist heat flow, and if they get wet they will lose this ability and increase the risk of mould and other moisture issues. If this happens, the insulation should be removed and thoroughly dried out. Depending on the area of the home being insulated, there are specific R-Values that need to be met in order to achieve an effective thermal and acoustic barrier.

Insulation in Antarctica

When working in Antarctica you have to protect yourself from freezing cold polar conditions. These include extremely low temperatures, freeze-thaw cycles, melting ice, strong winds and the ingress of water, grit and static electricity.

Buildings have to be able to endure these conditions for long periods of time and provide a place of comfort for scientists to carry out their work and for equipment. To do this buildings have to be clad with materials that can withstand these extreme conditions such as glass and metal. Buildings also need to be elevated so they don’t get buried by snowdrifts, and they have to be insulated to reduce conductive heat loss.

The best way to do this is with insulation and if you’ve ever visited Antarctica you will know how important it is! Most of the buildings are built on pillars to avoid snow accumulation and they are insulated with polystyrene, fibreglass or plastic foam. This is because these materials have small air bubbles inside which prevent the transfer of heat energy and keep the building warm.

To protect themselves from the freezing cold Antarctica weather, scientists wear a range of clothes made of natural fibres like woolen sweaters and trousers. They also wear hats, gloves and boots. Having more than one layer of clothing is important to stay warm as extra insulating layers trap air between them and also help you regulate your body temperature.
