Gypsum: the historical memory of creative evolution

Plaster offers a timeless charm and language

A traditional material handed down from older construction techniques

Gypsum has always been used in the construction industry, in combination with other inert materials, thanks to this feature it can be defined as a traditional material as it is used when older construction techniques are applied, and in the same time it can be considered also a very innovative material which fits the most modern and advanced solutions, able to compete with materials of higher technological level.

As raw material, thanks to its physic-chemical properties, gypsum has a wide range of technical parameters which allow to use Plasterego® products for many types of design, both stylistic and technological.

For this reason the company has a broad line of products available, which can be customized according to the specific needs from the customer while retaining their original features.
This can be obtained thanks to the use of special mixtures developed by Plasterego® which increase the hardness of the products, confer to them water repellence, reduce their weight, make plaster without chemical dyes and which can allow much more for other needs and purposes.

The most important gypsum technical qualities

Resistance and reaction to fire

The best known feature of the product is the ability to resist to fire. For this reason the plaster is always used within contexts where they are specifically required characteristics like fire-proofing, as identified by the relevant regulations.

The plaster product shows itself as capable of delaying the spread of flames due to its non-fuelling capability. The characteristic of fire resistance is increased by the modern construction techniques which can increase the drag coefficient.

Hygiene and healthiness

The natural healthiness of gypsum gives products Plasterego® an advantages it can be used in construction along with other materials. Since gypsum, as raw material has a completely natural origin, it does not enact with any kind of substances harmful to both people and the environment, even during the production process or its final application.
Plaster elements Plasterego® guarantee also the absence of traces of formaldehyde, regarded as one of the most harmful and polluting substances to human health among the volatile organic compounds which exist inside interior spaces.

Mechanical strength

The mechanical resistance characteristic is influenced by both the composition of the mixture and the type of plaster powder used. The cooking time of gypsum determines the allocation of different mechanical characteristics attributable to the raw material itself.

Plasterego® has over the years developed different plasters with many different levels of mechanical resistance higher than the average market standards. It must be said that those specific special plasters branded Plasterego®, which provide superior mechanical features, can also be applied along with other construction methodologies by combining different materials; the Company in addition to their plasters avails itself of the use of natural fibres found in nature which, once properly treated, become usable in the production process.

In the final design phase, on specific demands from customers, reinforcement structures designed for the special products made with plaster Plasterego® may be arranged.

Hygrometric regulation

Hygrometric power is given to plaster products directly by the raw material, which enables their power to keep a low level of moisture through the porosity of their plaster.

Plaster is obtained by drying, this process allows retaining the porous structure of the gypsum while preserving the ability to release humidity in line with the percentage contained in the air, in order to enjoy a constant healthy condition.

Certain hydrophobic plaster may also modify this property allowing gypsum products to be used also in environments with high level of steam particles in the air.

Thermal insulation

The thermal insulating power of a plaster product is given by the specific structure of the plaster, which, while drying, builds up a porous structure able to hold inside small air bubbles.

This feature allows significantly reducing the thermal conductivity. In addition, thanks to their uniform density, the plaster products guarantee the absence of those inner areas with less insulation capability.

Acoustic insulation

As for the power thermal insulator, even sound-mitigating and sound-absorbing capability are transmitted by the porous structure of gypsum.

The absorbing power allows lowering both the transmission and the reverberation of the sound through the environment. For this reason, both the application of plaster elements and the presence of walls may ensure the soundproofing in line with the latest regulatory constraints on this matter.

Light reflection

The natural characteristics of gypsum give the surrounding environments, where it is applied, the ability not to alter the colour of light sources.

In the same way, when treated with gypsum-based finishes, any surface increases its hygrometric capacity and therefore the healthiness of surrounding spaces.
