Insulation Perth prevents the transmission of heat, electricity and sound. It is available in many forms including blankets (glass fiber and mineral wool), blown-in or poured-in-place (cellulose, polyurethane, and foam) and boards/blocks (perlite, vermiculite).
Quality insulation reduces energy consumption for heating and cooling, which helps preserve non-renewable resources. It also reduces greenhouse gas emissions and the pollution associated with their generation.
Insulation is a material that’s installed in the walls, floors, and ceilings of a home or commercial building to slow the transfer of heat. It’s a critical component of any new home or re-insulation project, as it helps to reduce energy costs and increase comfort levels year-round.
Insulators can be made from many different materials, but the most common types include fiberglass and cellulose. They work by trapping air bubbles, which makes them resistant to the flow of thermal energy. This is why they are so effective at keeping homes warm in the winter and cool in the summer.
It’s important to note that insulators do more than simply slow the flow of thermal energy, though. They also help to insulate against air leaks, which can lead to significant energy loss. It’s this leaking that’s responsible for 50 to 70 percent of energy usage in the average American home, and reducing this airflow by adding insulation can significantly cut your heating and cooling bills.
There are multiple different types of insulation that can be used, including fiberglass, cellulose, and spray foam. Fiberglass is a popular choice due to its affordability and effectiveness, while cellulose is an eco-friendly option that’s derived from recycled paper products. Spray foam, on the other hand, is ideal for filling all of those little gaps and crevices that can contribute to air leakage.
Aside from preventing thermal energy loss, insulation can also serve as an air barrier and water vapor retarder, depending on the type of insulation and how it’s installed. This is especially true of foam insulation, which can be sprayed or injected into an open cavity like an attic, crawl space, or rim joist and then expands to fill the space. It’s also possible to install insulation yourself, if you have the proper equipment and follow safety precautions. However, it’s always best to hire a professional when working with any type of insulation, as improper installation can negatively impact the effectiveness of your insulation. This is particularly true for spray foam, which requires specialized tools and training to properly and safely install.
Types of Insulation
Insulation is made up of a wide range of materials that slow down the transfer of heat in and out of buildings. These products run the gamut from bulky fiber materials to sleek foils. They all work by trapping pockets of air within their structures to reduce conductive heat flow. Some are also designed to resist radiant flow, and thus help keep homes cool during the summer.
The most common type of insulation is fiberglass, which works by preventing heat from conducting through wall and ceiling spaces. It is available as blanket insulation (also known as batts or rolls) or loose-fill, and can be laid in between stud walls and ceiling joists. Fiberglass can be installed with minimal difficulty by DIYers, and is available at a variety of R-values. Other popular types of insulation include cellulose, mineral wool (rock and slag), and foam boards. Cellulose and mineral wool insulation are primarily made from recycled paper, while foam insulation is a combination of natural and manufactured materials. It is often coated in fireproofing chemicals such as hexabromocyclododecane (HBCD) to prevent the growth of mold and insects.
Blow-in cellulose, which is typically used in existing homes, has a higher R-value than fiberglass, and can be installed easily by professional home builders or DIYers. Other types of blown-in insulation include polyurethane foam, polyester matting, and reflective foil. Certain health-hazardous materials that were once widely used, such as vermiculite and urea formaldehyde, are now outlawed or unavailable.
Structural insulated panels (SIPs) are prefabricated, insulated structural elements for use in building walls, floors, and roofs. They offer superior and more uniform insulation compared to traditional stick-frame construction, and can reduce energy costs by up to 14%.
Foam-in-place insulation uses an open or closed-cell polyurethane formula to insulate walls, floors, and ceilings. Closed-cell foam is high-density and has a spongy texture, while open-cell foam has lower density and is less spongy. In general, closed-cell foam offers better R-values than open-cell foam. However, both options provide good thermal and sound insulation. Foam-in-place insulation can be a cost-effective choice for new construction and renovations, as it provides more R-value per inch than other insulation types.
How to Install Insulation
Whether you’re adding insulation to an existing home or building a new house, it’s important to understand what type and how much insulation is needed. This helps prevent the common mistake of overbuying or underbuying and will keep you from spending money on insulation that won’t provide the desired results.
To determine the amount of insulation you need, start by measuring the wall’s length and width. Use this information to calculate the number of stud bays and multiply by the wall’s height. This will give you the number of square feet of space to insulate. This will also help you find the best R-value for your project.
When insulating walls, make sure to account for window and door openings. Also consider the stud spacing and thickness of the framing. Insulation comes in standard rolls that are pre-cut to the correct size for each wall. The most commonly used insulation in homes is fiberglass batts, which are easy to cut for a precise fit.
Regardless of the type of insulation you choose, always wear a dust mask when handling it. Most types of insulation contain chemicals that can be dangerous if inhaled or swallowed.
Before installing insulation, check your local building codes for R-value recommendations and vapor barrier requirements. You’ll also want to seal any gaps that let unconditioned air into the space you’re insulating. These include areas where plumbing, ductwork and wiring enter the space.
If you’re insulating an attic, more insulation is required than is under flooring to avoid an updraft that draws cooler outside air into the home. It’s also recommended to overfill attics with insulation to increase the R-value, but this will add cost and complexity to your job.
When insulating walls, remember that the paper or foil face of the insulation should be facing the warm side of your home. This helps reduce condensation that can rob insulation of its R-value and encourage mold. For attics, it’s best to install a vapor barrier such as 6-mil plastic or MemBrain, which is a breathable sheet, before covering the insulation.
Choosing the Right Insulation
Insulation plays a big role in your home’s energy efficiency. It helps to keep a consistent indoor temperature, eliminating drafts and hot spots throughout your Peoria home. Proper insulation can help save up to 30% on your heating and cooling costs every year! It also reduces wear and tear on your HVAC equipment, extending its lifespan.
When selecting the type of insulation for your home, it is important to consider factors such as R-value, cost, recycled content, and embodied carbon. You should also consider how often the area will need to be accessed for maintenance, repair or inspections so that you can choose the right option for your particular circumstances.
In addition to choosing the right insulation material for your home, it is important to properly install it. Incorrect installation can lead to ineffective insulation, resulting in high energy bills and reduced comfort. Common mistakes include incomplete coverage, using the wrong insulation type, and neglecting to address air leaks in the building envelope.
Fiberglass batt insulation is an inexpensive, readily available insulation that offers good thermal performance for its price. It works well in most areas of the home, but may not be as effective in cold climates and is limited in its ability to block radiant heat.
Cellulose insulation is made from recycled paper materials and offers excellent R-values for its price. It is treated with fire-retardant chemicals to enhance safety and is a great choice for green homeowners. Spray foam insulation is another highly-efficient option for new construction and existing homes. It is sprayed into walls, attics, and crawl spaces and expands to fill cavity areas, providing an effective barrier against heat loss.
While it is possible for homeowners to install certain types of insulation, professional installation provides many benefits, including access to wholesale pricing, efficient installation, and warranties. Expert installation will ensure that the insulation is installed correctly, maximizing its effectiveness and saving you money in the long run.
The right insulation will not only lower your energy bills and create a more comfortable living space, but it will also have a positive impact on the environment. By reducing waste, pollution, and greenhouse gas emissions, insulation contributes to a more sustainable future for all of us.
