Fiberglass Blanket In Nairobi Kenya and East Africa +254 722 401 175

Insulation World Kenya Limited is the leading direct importer and distributor of high density  fiber glasswool insulation blankets in Nairobi Kenya and East Africa.

Fiberglass insulation, also known as glass wool, is one of the most effective and sustainable insulation materials on the market. The exceptional thermal properties help save energy and therefore reduce emissions. The porous, elastic structure means that glass wool is very good at attenuating noise. Glass wool doesn’t fuel fire or propagate flames either, as it is incombustible by nature.

What is Fiberglass Insulation?

Ever wondered what fiberglass insulation is all about? Well Fiberglass insulation is the oldest and popular acoustic and thermal insulation material in the World. Glass wool insulation has existed in the insulation market for over 80 years.

Manufacturing Process of Fiberglass Insulation

Glass wool is made of sand, recycled glass, limestone and soda ash. These are the same ingredients that are used to make familiar glass objects such as window panes or glass bottles. The glass is spun to form millions of fine fibers.

  1. BATCH: Glass wool is made mainly of sand, soda-ash, limestone and recycled glass; stored in silos, they are weighed, mixed and poured into a furnace.
  2. MELTING: The mixture is then melted at a temperature exceeding 1,400°C in an electric or gas furnace.
  3. FIBERIZING: The liquid glass passes via a feeder to a fiberizing machine, where it is propelled through tiny holes by a centrifugal spinner – creating the fibers. These are sprayed with a binder and shaped into a blanket.
  4. FORMING: Then the blanket passes through a curing oven. During this process, the blanket can be compressed to achieve its final thickness.
  5. CUTTING: The blanket is then cut to the required width. Off-cuts are recycled. A facing can eventually be glued to the blanket..
  6. PACKAGING: The end of the line is generally equipped with a rolling machine for mats and a stacking machine for boards.
  7. PALLETIZATION: The glass wool can be compressed to up to a tenth of its volume. A total of 36 rolls of glass can be packed onto a single pallet.

Fiberglass Insulation Hazards

Fiberglass insulation may cause temporary irritation to the skin, eyes and respiratory tract. Avoid contact with eyes and skin, wear loose-fitting, long-sleeved clothing, gloves and eye protection when handling and applying the material. Wash with soap and warm water after handling

Unusual Fire Hazards: Fiberglass insulation is a non-flammable product. The foil facing and packaging material can burn. Caution should be observed not to expose the packaging or foil close to direct flame. Chemicals in adhesives, facings or plastic packaging products that do not present a health hazard under normal conditions may be released during a fire. Toxic fumes and gases that may result from incomplete combustion include carbon monoxide, hydrogen chloride and low-level cyanides. In case of overexposure, remove to fresh air. If breathing is difficult, administer oxygen and consult a physician

Fiberglass for Thermal Insulation

Fiberglass insulation blankets have become a product of choice in thermal (heat) insulation applications in Kenya. The Fiberglass blankets have a temperature rating of 538°C, making it ideal variety of places. In addition to excellent thermal insulation properties, fiberglass is lightweight, flexible and cost effective.

Boilers & Steam Pipe lagging: Most steam boilers used in food industries use fiberglass blankets as the primary insulation material due to the low costs and effective thermal insulation. It is also light in weight making suitable to use in steam pipe lagging.

Ovens, Barbecues, Fireplaces: Pizza Ovens and barbecues among other domestic ovens get very hot which can lead to injuries to the users. Fiberglass insulation comes in handy as oven insulation material due to the excellent thermal insulation properties and durability.

Roof Insulation/Ceilings: Fiberglass insulation blanket is used for insulation in hot or cold areas due to lightweight and cost effective. These applications include both residential houses, office blocks or industrial uses.

Shipping Containers & Container Houses: The rise of container houses has led to a rise in demand of fiberglass blankets in Kenya. Compared to other thermal insulation materials for containers, fiberglass blankets are economical, technically better and due to high fire rating.

Fiberglass for Sound Insulation

Fiberglass blankets have good Sound insulation properties. The 50mm has a Noise Reduction Co-efficient (NRC) value of 0.80 which is way ahead of many other sound insulation materials available in our market.

Fiberglass insulation is very economical and easy to install within studs and timber joists. Based on experiments glass wool has an R-Value of 2.2 to 2.7 per inch which is lower than that of rock wool insulation. Mineral wool or rock wool has an R Value of 3.0 to 3.3 per inch.

You can use fiberglass insulation blankets for sound absorption and sound proofing of;

  • Studios, Audition halls: music or radio studios and audition halls use fiberglass in their construction to absorb the noises around or prevent echoes.
  • Board room: Corporate board rooms are currently using fiberglass in their construction to ensure they are soundproof.
  • Residential Houses: Fiberglass insulation to soundproof houses near busy roads or industries. This also includes the container and sheet houses.
  • Schools and Hospitals: Fiberglass insulation to soundproof schools and hospitals near busy roads or industries to ensure conducive environment.
  • Entertainment joints: Night clubs, as well as matatus and personal cars use fiberglass blankets for sound insulation.
