Roof insulation can help you save money on your heating and cooling bills and prevent your roof from leaking, which otherwise can cause damage to your home’s foundation, walls, and ceiling. There are numerous types of roof insulation available in the market these days. In this article, we will be introducing you to some 5 types of Roof Insulation that you can choose for your home or your commercial building.

What are the Top 5 Roof Insulation Types?

We are going to discuss the five best roof insulation types you need to know:

1 Fiberglass

Fiberglass is one of the most commonly used insulation materials. It’s typically inexpensive and is easy to install. However, says it doesn’t offer as much R-value per inch as other types of insulation. One significant advantage is that fiberglass provides good fire resistance and can even help prevent mold in humid surroundings, like basements. Fiberglass comes in bats or rolls.


This synthetic insulation offers a range of benefits for residential homes. It’s widely used in radiant barrier roofing. It uses reflective coatings and specialized building materials to reduce energy costs by reflecting sunlight away from your home. Fiberglass also has R-value ranging from R-3.2/inch up to R-5/inch depending on its thickness, so it’s an efficient option that can help you keep your energy costs low.


Fiberglass insulation is an off-the-shelf option that is typically cheap and easy to install. While fiberglass insulation is easier to work with, it doesn’t hold up as well over time.

2 Synthetic Foam

Synthetic foam is a versatile product used in several applications, including roof insulation. It comes in various forms, so it’s essential to understand what type of synthetic foam is an ideal choice for your home’s roof.


Synthetic insulation is undoubtedly one of, if not THE best, type of roof insulation out there. It has outstanding acoustic and thermal efficiency, as well as excellent stability and is fire resistant as well. It is available in a variety of thicknesses, and you can attain your desired R-value (the measure of temperature difference) regardless of your finances or budget.


It may contain up to 25% asbestos, an environmental carcinogen. Most of today’s synthetic fiber insulation is made from polyester, a petroleum-based product that emits toxic fumes when burned. Loose synthetic fibers can shed into your home and irritate the skin, causing rash and other allergic reactions.

3 Cellulose

This type of insulation is composed of recyclable materials. There are two types of Cellulose Insulation: loose-fill cellulose and bats. Loose-fill cellulose comes in giant bags and can be blown into attics from above or poured into wall cavities during home construction or renovation.


Cellulose insulation is made from recycled newspaper, and it provides nontoxic natural insulation that’s eco-friendly. Cellulose is indeed simple to install and requires only a cordless drill and a measuring tape to install. The best part about cellulose is that it’s highly effective at reducing air leakage, making your home more comfortable in cold weather.


Cellulose-based insulation is never eco-sustainable, even though it is based on renewable resources.

4 Mineral Wool

Mineral wool is made from rock, slag, or sand that has been heated until it becomes a molten liquid. The molten substance is spun into fibers and combined with an adhesive to make bats. The bats are placed between layers of building paper and fastened to wood or metal decking as insulation on a roof’s surface. On a per-pound basis, mineral wool is one of the most affordable types of insulation currently offered.


Mineral roof insulation can last for up to 30 years. It’s also highly fire-resistant, making it one of the best roofing options in areas with a high risk of wildfires. This insulation option is also relatively affordable and easy to install, making it an attractive choice for homeowners looking for ways to save money on energy bills.


The main disadvantage of using mineral wool is its high price and installation cost.

5 Bubble Wrap

Bubble wrap insulation may seem like a no-brainer, but not all bubble insulation is created equal. Make sure you invest in high-quality bubble plastic that keeps your roof protected from heat transfer, moisture, and temperature swings. Cheap bubble wrap is easy to spot: If it starts bubbling out of its own accord, or if it’s light and moves around quickly when shaken, it won’t provide enough protection for your roof.


With its high R-value, bubble insulation effectively stops heat from escaping your home and helps lower energy bills, and keeps a comfortable living environment. Because it consists of preformed small pellets, you don’t have to worry about loose fibers or hair getting caught in any ventilation system or ducts. It also has anti-microbial properties that help reduce mold growth in your attic by cutting off excess moisture.


Polystyrene bubbles insulate your roof from heat and cold, but there are some significant downsides to consider.

First of all, when it gets hot, bubbles become soft and deteriorate more quickly than other types of foam insulation.


If you do not have the correct insulation, you will spend more on your heating and cooling bills. Hence it is crucial to acknowledge the best roof insulation alternatives in order to make the best decision for enhancing the performance of your home.
