A Buying Guide for Foil Insulation

Reflective foil insulation is usually made from several layers of aluminium foil that are combined with air and soft wadding. The main purpose of such insulation is to reflect radiant heat. This is a modern alternative to traditional materials such as fibreglass, which is often not as effective. Foil insulation can reduce the radiant heat transfer by up 97 per cent. When shopping for foil insulation, buyers should be aware of the fact that there are several variations and that is important to make sure the material they choose meets all the requirements of building regulations.

Foil insulation is a cost-effective and easy to fit insulation product that works well with both new and retrofit building projects. Foil insulation is especially designed to keep the house warm in winter, but the unique foil properties are also great at reflecting excessive heat during the summer. By learning more about the characteristics of foil insulation and how to buy the necessary materials, buyers can make sure their insulation is the right choice for their building while being cost-effective at the same time.

What is Foil Insulation?

Foil insulation is made up of multiple sheets of metallised film that are separated by an insulating core. Aluminium is a widely used material for the metallised part, whereas for the insulation core manufacturers may use various combinations of plastic bubble sheet, plastic foam, and non-woven fibrous wadding. The entire assembly needs to be installed with quilt edges and sealed joints in order to be effective.

The main function of foil insulation is to add more comfort to a building and reduce energy bills, sometimes as much as 50 per cent. This works by preventing heat from escaping conditioned spaces and thus reducing heat loss. Buyers often choose to insulate their home using foil instead of fibreglass as this option is usually more cost-effective in the long term.

The History of Foil Insulation

Radiant barriers have been used in both residential and commercial buildings since the first decades of the 20th century. Aluminium itself began to be used for foil at the end of the 19th century, but it was not employed for insulation purposes until the end of the Second World War. This was a period in which aluminium started to be used for multiple purposes and it was made available for commercial use in large quantities. Nowadays, reflective foil insulation is commonly made from aluminium-based substances. The reason behind this is the efficiency of this material when it comes to reflecting heat.

How to Find the Right Type of Foil Insulation

There are several types of heat retaining material one can use when it comes to foil insulation. Most of these materials are quite efficient at protecting a home or commercial building and obstructing the heat from breaking through. Choosing the right type of materials for insulation is a matter of preference and budget and buyers should opt for the materials that best suit their needs.

Aluminium Bubble Foil

One of the materials that is commonly used for insulation is aluminium bubble foil. This may be either single or double and it is available in a variety of widths and lengths. The double foil often has aluminium on both sides. Another type of foil insulation features aluminium on one side and polyethylene on the other. The main benefit of using double foil for insulation is the fact that this material withstands temperatures varying between minus 15 degrees Celsius and plus 82 degrees Celsius. In most cases, double foil bubble insulation is a good choice, regardless of the size of a project, as it can be installed fast and easily. In addition to that, it is fully recyclable, reduces noise pollution, is resistant to corrosion, and is very flexible.

Multi-Foil Reflective Insulation

Multi-foil insulation is another commonly used material and it is ideal for under floors, walls, and ceilings. This can add a radiation thermal barrier to a variety of structures, thus preventing the radiated heat from escaping the building. This type of foil is not as thick as the aluminium bubble one and it is thus ideal for enhancing the energy performance of a building where a very small depth is possible. Multi-foil insulation also helps preventing mould and damp, enhances thermal resistance, and reduces the risk of condensation. Buyers can choose to purchase it in rolls of different widths and lengths. Aluminium foil tape is another useful supply for foil insulation projects and it can be used in any situation where ultraviolet resistance and good adhesive strength is required.

What to Look For in Foil Insulation

In order to be able to choose the right materials for foil insulation, buyers should first be aware of the building codes for insulation in their area as well as their preferences when it comes to the average temperature they would like to obtain in the building. The direction of heat flow and the depth of the air space should also be taken into account, as these may influence the amount of thermal resistance provided by the foil insulation. Choosing the right type of foil insulation can be a rather difficult process for someone who is not a specialist, so buyers may want to consult with an expert prior to making a purchase.

Installation Tips for Foil Insulation

Simply buying the right type of foil is not enough for a successful insulation project. The installation of the foil needs to be done carefully in order to obtain the best results. There are several things to take care of prior to starting the insulation process. The job area needs to be inspected carefully for any signs of air or water leaks. If any leaks are found, they should be sealed. Foil insulation can be installed in a variety of locations, with some of the most common options including floors, walls, and attics. Other common locations for foil insulation projects are crawlspaces and basements.

The rule of thumb for any type of space is that it needs to be properly ventilated. The air needs to be able to circulate properly in order for the foil insulation to have the desired effect. One should, for example, use ridge vents along the roof lines. The climate where the building is located and the owners' objectives should dictate the approach to the insulation project of any building. Buyers who are mostly interested in reducing their winter heating bills may opt for installing the foil on top of other existing insulation. This is actually the preferred method of installation for mixed-climate locations.

How to Buy Foil Insulation on eBay

If you are planning an insulation project for your building anytime soon, you need to search the market for the right supplies. When shopping for foil insulation, you need to set up a budget and then compare the market for the best prices and deals. Insulating a building, either commercial or residential, may prove to be a costly process, but with careful budgeting, you can avoid unpleasant surprises. eBay is a good place to start the search for the materials you need for your projects. By using this website, you can shop around for good prices from various vendors and easily spot great deals.

Besides offering a good selection of foils and additional materials needed for an insulation project, eBay also provides buyers with a search system that can allow you to find what you are looking for in no time. For example, you can start the search quite easily, by typing the words 'foil insulation' into the search bar of the website. You can find this on any eBay page. If you already know exactly what kind of foil you intend to buy, you can save time by simply typing in the name of that specific product. Another benefit of using eBay when shopping for foil insulation is the possibility of narrowing down the results by price. This makes it easier for any buyer to have a look only at products that are in their price range.

Conclusion

When compared to other types of insulation, foil insulation can make one's life easier while cutting their energy bills significantly. Aluminium foil insulation is a very cost-effective type of insulation and it is also a good choice for those who are interested in protecting the environment, as aluminium can be easily recycled. Foil insulation does not usually require the assistance of an expert during the installation process. The foil is easy to cut and fit and, as a result, anyone can do it with a bit of exercise. In addition to that, foil insulation does not consume any of the living space, as it is thin and does not take up as much space as other insulators.

The secret to a successful foil insulation project is to use the right materials. Buyers can choose to purchase foil insulation supplies from specialised stores or online.
