The Different Types of Roof Insulation Materials in Kenya

There are several types of roof insulation materials available at Insulation Materials Kenya. The most common type is GCS Roof Insulation Polyethylene Foam which is more affordable and durable. Another one is fiberglass, which is made from recycled glass and plastic. Other types of insulation include polyethylene foam, polyurethane, mineral wool and polystyrene. Fiberglass and GCS Roof Insulation are the most popular type of insulation because they are inexpensive and easy to install. Cellulose is made from recycled paper products and is also fairly inexpensive. Mineral Wool rockwool is a more expensive option but it has a higher R-value, which means it will keep your home cooler in cold seasons and warmer in hot seasons.

As with any building material, there are advantages and disadvantages to using different types of roof insulation materials in Kenya. Here is a rundown of the most popular materials used for roof insulation, as well as the benefits and drawbacks of each.

1. Polyethylene Foam Insulation

GCS roof insulation is perfect and widely used in Kenya. Sometimes referred to as alububble, sisalation or reflective foil insulation. We manufacture the rolls by sandwiching the polyethylene foam between high density foil wraps, which has the advantages of reflecting and insulating heat. The more the core thickness, the better the soundproofing and waterproofing properties.

Here is a list of the most used GCS Roof insulation materials in Kenya

The air energy of GCS roof insulation material can not only insulate most of the heat in hot seasons but also reduce the loss of indoor heat and the invasion of external cold air in cold weather. It can be said that it is a product that can play the role of temperature regulation under any weather conditions.

GCS roof insulation material is the perfect thermal and sound insulation material in residential and commercial buildings, workshops, churches and other large-scale buildings, especially during the rainy season when the indoor noise is very high; using our products can greatly reduce the noise caused by rain and wind and provide a quiet and calm environment.

GCS roof insulation material is different from other products on the market. The width of 1.9m and a length of 50m brings more than twice the convenience for your construction. Advanced and sophisticated equipment ensures that our products’ quality is at the forefront of the industry. Our strong company background gives you the perfect after-sale service. We have thicknesses of 3mm, 5mm, 10mm, 20mm and 25mm insulation

2. Fiberglass Insulation

Fiberglass Insulation is one of the most popular choices for roof insulation due to its affordability and effectiveness. It is also easy to install, making it a good option for do-it-yourselfers. However, fiberglass can be Itchy to work with and install, and it doesn’t provide as much soundproofing as some other materials. We have different types of fiberglass insulation to fit your needs.

3. Mineral Wool Insulation – Rockwool

Insulation effectiveness is measured in terms of ‘R-value’; the higher the R-value, the better the insulation. Mineral wool batts and rolls have an approx R-value of 3.1 – 3.4 per inch, but we recommend checking the supplier’s datasheet. Mineral wool insulation offers excellent fire resistance properties and withstands temperatures of up to 850 degrees. It’s also great in the case of water damage – unlike some of the alternatives, if mineral wool gets wet, once dried again it will continue to provide effective insulation

4. Cellulose Insulation

Cellulose is another affordable insulation material that is made from recycled paper products. It does a good job of filling in spaces and sealing off air leaks. However, cellulose can be difficult to install properly, and it can absorb moisture, which can lead to mold or mildew growth if not remedied quickly.

5. Spray Foam Insulation

Spray foam insulation is one of the more expensive options, but it is also one of the most effective. The foam Spray expands to fill in cracks and crevices, creating a tight seal that helps keep energy costs down. The downside to spray foam is that it can be messy to work with and install, and it isn’t always compatible with all types of roofs

Which Material is the best for Your Home?

There are many roof insulation materials available on the market, but not all of them are created equal. Some materials are better suited for certain climates and applications than others. When it comes to selecting the best roof insulation material for your home, it is important to consider both the R-value and the perm rating.

The R-value is a measure of thermal resistance and measures how well a material insulates. The higher the R-value, the better the material is at insulating. The perm rating is a measure of how much water vapor can pass through a material. A high perm rating means that more water vapor can pass through, which can be beneficial in hot and humid climates.

Fiberglass batts are one of the most popular types of roof insulation materials. They have a high R-value and are relatively easy to install. However, fiberglass batts can be itchy and difficult to work with if you are not wearing gloves or other protective clothing.

Cellulose insulation is another popular option. It is made from recycled paper products and has a very high R-value. Cellulose insulation is also treated with chemicals that make it resistant to fire, mold, and pests. This type of insulation can be difficult to find in some areas, but it is definitely worth looking into if you want an eco-friendly option with a high R-value.

Rock wool insulation is another great option for those who want an eco-friendly product

Why do We Need Roof Insulation?

By installing effective insulation in homes and commercial buildings, heating costs can be reduced by as much as 70%1. Homes without effective insulation will lose about a quarter of their heat through the roof. Besides escaping warm air, a roof that isn’t in good shape can also let cold air in.

Keeping a building cool is essential in hot climates.

With insulation, you can convert a loft area into a living area or an extra bedroom, or create a welcoming terrace or green roof on a flat roof.

There are several benefits to insulating a flat or pitched roof:

  • Heat transfer should be prevented
  • Enhance a property’s energy efficiency
  • Save money on heating costs
  • Reduce a property’s carbon footprint
  • Enhance summer comfort

How to Install Roof Insulation

There are two types of roof insulation: loose-fill and batt.

  • Loose-fill is made up of small pieces of insulation, such as fiberglass, that can be blown into place with a special machine.
  • Batt insulation is made up of larger pieces that are placed between the studs in your walls.
  • Roll insulation like polyethylene foam are screwed on the underside of the roof or installed before the iron sheets

To install loose-fill insulation, you’ll need to rent a machine that blows the insulation into place. You’ll also need to wear protective gear, such as a dust mask and earplugs, to avoid inhaling the insulation particles.

To install batt or roll insulation, you’ll need to measure the space between the studs in your walls and cut the insulation to fit. You’ll then need to staple or glue the insulation in place. Again, you’ll want to wear protective gear to avoid inhaling any fibers.


Roof insulation is an important component of a home’s energy efficiency and comfort levels. The materials used for roof insulation in Kenya vary, depending on the type of building and the climate. We have gone over some of the most common types of roof insulation materials used in Kenya. They include fiberglass, foam board, cellulose, wool and recycled denim, polyethylene foam and rockwool. Each insulation has its own pros. and cons. Be sure to research which one best fits your budget and climatic needs before purchasing. Insulation materials Kenya team offers free technical.
