Fiberglass specific weight: weight of 1 m³ and density
Fiberglass is a composite plastic material consisting of a glass-fiber filler, meaning fibers made of glass, quartz and similar materials, and a binder: thermosetting or thermoplastic polymers. This material has low specific weight and certain preset properties, is used widely and has a broad range of applications.
Among the properties of fiberglass are low thermal conductivity, high specific strength, resistance to moisture, biological and atmospheric effects. It is also worth noting that fiberglass properties depend on the type of binder, reinforcement and production technology.
Various products are made from fiberglass: window, door and similar profiles, many products with high resistance to water and moisture, such as hot tubs, water attractions, boats, as well as various products for mechanical engineering and protection applications.
Fiberglass specific weight table
The table below contains average values for such indicators as the specific weight of fiberglass, its density and the weight of one cubic meter of fiberglass. This table will help perform the necessary calculations, including such a parameter as fiberglass weight.
| Material | Specific weight, g/cm3 | Weight of 1 m3, kg |
|---|---|---|
| Fiberglass | From 0.4 to 1.8 | From 400 to 1800 |
Specific weight calculations
For practical calculation of fiberglass mass, material density and the weight of one cubic meter are usually used. The values in the table are approximate: actual density depends on binder composition, reinforcement type and material grade.
The density of a material or substance is its mass, measured in kilograms, contained in one cubic meter. This parameter depends on many factors, such as temperature. Fiberglass density ranges from 1800 to 2000 kg/m3.
Frequently Asked Questions
Can the density of fiberglass be used for precise calculations?
The density and weight values for fiberglass in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of fiberglass differ from the table?
The actual weight of fiberglass depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of fiberglass from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of fiberglass is given in kg/m³ and the volume is in m³, the result will be in kilograms.
