Grand Full Polystyrene Beads
Grand Full provides a flexible alternative to traditional sheet insulation for enclosed building cavities. The free-flowing material conforms to the available space, making it suitable for structures where rigid insulation can be difficult to fit.
What makes Grand Full polystyrene beads unique?
Balticfloc Grand Full is a loose-fill insulation material made from small expanded polystyrene (EPS) beads. Each bead has a cellular internal structure filled primarily with air, giving the material its low weight and thermal insulation properties.
The small, free-flowing beads can spread throughout a cavity and fill spaces with irregular shapes, creating an even layer of insulation.
How do individual EPS beads form an effective thermal insulation layer?
An insulation material does not need to be a solid board to effectively limit heat transfer. With Grand Full, the insulation layer consists of many EPS beads packed closely together.
Each bead contains sealed, air-filled cells, with small amounts of air remaining between the individual beads. Because air is a poor conductor of heat, this structure helps limit heat transfer through the filled cavity.
Even distribution is important for effective insulation. Completely filling the cavity reduces the likelihood of larger air gaps that could allow increased air movement.

How are Grand Full polystyrene granules manufactured?
Grand Full EPS beads are produced through a controlled process that gives the material its characteristic cellular structure. Each stage helps achieve the particle size and bulk density required for consistent performance as a loose-fill insulation material.
Raw material preparation
Production begins with small polystyrene beads containing a blowing agent that allows them to expand during the next stage. The beads are prepared for further processing and fed into the production equipment in controlled quantities.Pre-expansion
The polystyrene beads are evenly heated with steam, activating the blowing agent. As the beads expand, they increase several times in volume and develop the closed-cell structure characteristic of EPS.The temperature, processing time, and degree of expansion are controlled to achieve the required bulk density.
Bead stabilization
After pre-expansion, the Grand Full beads are left to stabilize. During this period, pressure within their cells equalizes as air gradually enters the beads, creating a more stable structure.This process helps minimize variations in bead size and density in the finished product.
Sorting by particle size
The beads are sorted by size, with non-conforming material and unwanted impurities removed. Blaticfloc Grand Full beads do not exceed 6 mm (0.24 in.) in size. Controlling the particle size helps ensure a uniform loose-fill material and consistent behavior during installation.Packaging
The finished product is packaged for transportation and storage. The packaging prevents the lightweight, loose-fill material from spilling and protects it from contamination before installation.What are the advantages of Grand Full polystyrene beads?
When selecting thermal insulation, it is important to consider how well the material will maintain its properties over the life of the building. The closed-cell structure of Grand Full helps the material maintain long-term performance after installation.
Grand Full beads do not settle significantly or absorb large amounts of moisture. Because the material is not biodegradable, it retains its shape and volume over time, reducing the risk of voids forming within the insulation layer.
Unlike sheet insulation, polystyrene beads do not need to be cut to size, so installation produces no material offcuts. This allows more of the purchased insulation to be used and reduces material waste.
Grand Full is installed as a dry, loose-fill material that produces no fiber dust and requires no on-site mixing or wet application. The beads are easy to clean up once the work is complete, making the installation process especially convenient for renovation projects in or near occupied spaces.

Questions and answers
Are polystyrene beads fireproof?
No. Expanded polystyrene is a combustible material, so its use must be considered as part of the overall building structure. Fire safety depends on the design of the structure, the materials surrounding the insulation, and any additional fire protection measures. In building applications, polystyrene beads are typically installed behind protective structural layers.
Can polystyrene beads be recycled?
Yes. EPS is a thermoplastic material that can be mechanically or chemically recycled and used to manufacture new products. However, recycling options after the material is removed from a building depend on:
- whether the beads can be separated from other building materials;
- whether they have been contaminated.
How long does this type of thermal insulation last?
EPS is designed for long-term use in building structures. Studies indicate that loose-fill expanded polystyrene insulation can retain its essential properties for at least 50 years under suitable operating conditions.
The actual service life depends on the condition of the building structure and the quality of the installation. As a result, the service life of the insulation may vary between buildings.
