A properly insulated home delivers a range of benefits to homeowners, including increased energy efficiency and savings. For many, having a properly insulated home means adding insulation to the walls, ceiling, or roof. By learning about the different types of insulation available and how to install it, homeowners can upgrade their homes and get on the road to better efficiency. Those in search for insulation can benefit as well from exploring product options available on eBay that go beyond the traditional brick-and-mortar retail models.
Choosing the right type of insulation for homes
There are two main categories of insulation used in homes, including reflective and bulk. Bulk insulation primarily relies on air pockets within its structure to trap heat, preventing it from going out during the winter and coming in during the summer. Bulk insulation comes in a range of materials that include:
- Glass wool
- Cellulose fibre
On the other hand, reflective insulation uses an aluminium laminate to reflect heat away. Homeowners can find this type of insulation in sheets, concertina-style batts, and multi-cell batts.
Deciding between bulk and reflective insulation
Homeowners need to consider several factors when choosing between bulk and reflective insulation. Bulk insulation is more efficient at keeping heat in for houses in colder climates. Reflective insulation is a better choice for keeping heat out in warmer climes. The aluminium surface of reflective insulation also resists mould and vermin quite effectively. Bulk insulation can be more cost-effective, however, when insulating an entire structure.
Understanding the R-value of insulation
The R-value of insulation is a number used to indicate how powerfully it keeps heat in or out of a structure. A higher R-value means less heat is getting in or out through the insulation. According to the Building Code of Australia, homeowners want a minimum R-value of 4.1 in ceilings and roofs and an R-value of 2.8 in walls. This can go as high as 6.3 and 3.8 respectively in colder climates around the country.
With bulk insulation, this number is easy to understand — each type of bulk insulation, be it wool or glass, has a set R-value for a particular thickness. Calculating R-value with reflective insulation is more complicated, since the insulation itself does not have a set R-value. Homeowners can only calculate the R-value of reflective insulation by considering the insulation itself along with the air space above the reflective surface after installation. This air space serves as a thermal layer that supplements the insulation's performance.
The first step in any installation project involves donning the correct safety gear. It is crucial that homeowners always wear goggles, work gloves, a dusk mask, long pants, and a long-sleeve shirt when working with insulation. This ensures the utmost protection throughout the insulation process.
Choosing an installation space
Next, homeowners should carefully measure the space where they want to install the insulation so that they can calculate how many square metres of a particular type of insulation they need. It is important to leave as few gaps as possible. Exceptions include leaving safety clearances for hot items in a space, including downlights, transformers, and fireplace flues. It is also important to leave venting space when insulating a metal roof.
Getting the most out of insulation during installation
When installing bulk insulation, homeowners need to make sure that the insulation has ample room and retains its normal thickness. Compressing the insulation reduces its performance. Once bulk insulation is in place, homeowners need to restrain it with perforated reflective foil laminate or non-corrosive wire.
The primary concern when installing reflective insulation is that homeowners maintain at least 25 mm of air space above the aluminium surface. Homeowners should also install reflective installation facing downward or resting vertical to reduce the amount of dust that can settle on the surface.
How to buy insulation and supplies on eBay
Homeowners can find a wide variety of insulation products and supplies from the reliable sellers on eBay. To begin the process, look for the search bar on any page of the site and run a keyword search for an item. For example, search for products such as "insulation" or "bulk insulation". Do not forget to review items on the resulting list in detail by clicking on their titles. Efficiently insulating a home is essential to a home's operational costs. By selecting the right insulation and installing it correctly, homeowners can ensure that their homes run as effectively as possible.
