Mirka® Styro System

Clean Solution for Styrofoam Insulation

The Styro System brings Mirka's ergonomic wall sanding to insulation panel installation, complete with Mirka's dust-free sanding system for a quick and clean process.

Save Energy with Better Insulation

To save energy, buildings can be fitted with exterior insulation panels on the walls of the house. This helps to improve the containment of heat, and less heating energy is wasted.

Fitting insulation panels requires trimming them to correct size and leveling the panels so they can be painted and decorated. Without sanding the panels, the edges will stand out and make the building look unfinished, or make applying paint difficult.

Easy, Clean and Fast

Complete Solution

With the help of Mirka’s new Styro System, fitting polystyrene insulation could not be cleaner. Usually, when leveling panel seams to achieve a uniform structure, debris is created from sanding insulation foam. To solve this, Mirka’s ergonomic and easy-to-use LEROS-S wall sanders are fitted with a special backing pad and Mirka Styro abrasives together with an interface to make sanding work easy, clean, and fast.

Suitable for all types of polystyrene

Abrasive Technology

The system is suitable for sanding underground and external insulation panels alike, for Extruded Polystyrene (XPS) and Expanded Polystyrene (EPS). With the specially developed Mirka Iridium abrasives for the Styro System, debris extraction capability is improved even further. Mirka offers different grits to suit different density of polystyrene, from P40 to P80.

Reduce strain and speed up your work

Ergonomic Sanders

Mirka’s LEROS-S wall sander is designed to reduce strain on the operator, helping you to make quick work of the job at hand. Thanks to efficient abrasives and powerful dust extraction, you can minimize both the time needed for the sanding process and the amount of debris from sanding foam.

The combination of ergonomic sander design and dust-free sanding reduces discomfort as well as the risk of occupational disease, especially in tackling large areas such as wall insulation.

What is the Mirka Styro System?

Questions and Answers

Which abrasives are included in the Styro System?

The Styro System features Mirka’s Iridium abrasives, developed specially for the system with larger dust extraction holes.

Do I need to use an interface?

An interface is an essential part of sanding insulation to make sure the panels are completely level. The interface and backing pads in the Styro System are developed to direct large debris created from sanding polystyrene.

What is the difference between insulation panel materials?

Mirka Styro is suitable for sanding both extruded and expanded polystyrene. Extruded, or XPS polystyrene is denser, and expanded, or EPS polystyrene is more lightweight, with the choice of panel depending of its purpose and whether it is fitted underground or externally. Choose the correct grit of abrasive to make sure the sanding process is optimized.

How to select the right abrasive?

For sanding dense extruded polystyrene (XPS), we recommend grit P40. For an all-purpose grit, for medium density EPS insulation, choose grit P60. When sanding wall insulation made from light density EPS insulation, choose grit P80.

What is the benefit of using a Mirka LEROS-S sander?

The Mirka LEROS-S is designed for sanding large surfaces with a secure grip and a large pad. It is easy and light to use, making work quicker and leaving a better finish quality at the same time. It is compatible with Mirka’s dust-free sanding solutions that are an important part of the Styro System.
