Composition and Technology
Sandwich Tile's innovation and effectiveness derive from its ingenious composition of three distinct layers, combining advanced material technologies to provide superior insulation, durability and aesthetic flexibility. Let's take a closer look at each layer, highlighting the material options and their advantages.
Outer layer: Galvalume Steel and Galvanized Steel
The outer layer of Sandwich Tiles can be manufactured from either Galvalume steel or Galvanized Steel, offering builders and architects flexibility according to the specific needs of the project.
- Galvalume Steel : This aluminum-zinc coated steel alloy is highly resistant to corrosion and is chosen for its longevity and ability to withstand harsh environmental conditions. Its surface reflects solar radiation, contributing to the thermal efficiency of the building.
- Galvanized Steel : Galvanized steel, coated with a protective layer of zinc, also offers excellent protection against corrosion. Although it is slightly more susceptible to damage from scratches compared to Galvalume, it is an economical and durable option that is widely used in a variety of construction applications.
Intermediate Layer: PIR or PU Foam Insulation
Inside the Sandwich Tile is the intermediate layer of insulation, generally composed of Polyisocyanurate (PIR) or Polyurethane (PU) foam. These foams are chosen for their exceptional insulating properties, both thermal and acoustic, which help maintain stable internal temperatures and reduce noise, promoting comfortable and energy-efficient indoor environments.
Insulating Core Material
- Polyurethane (PU) : Provides excellent thermal insulation and is very light. It is one of the most common types of insulation used in sandwich tiles, balancing cost, performance and weight.
- Polyisocyanurate (PIR) : Similar to PU, but with greater fire resistance and better thermal performance. It is ideal for applications that require a higher fire resistance rating.
- Rock Wool : Offers excellent thermal and acoustic insulation properties, in addition to being non-combustible, which provides even better fire resistance. Ideal for places that require sound insulation or are subject to fire risks.
Inner Layer: Painted steel for aesthetics and protection
The inner layer, facing the interior of the building, is made of painted steel. This layer not only serves as an additional barrier against moisture and other indoor elements, but also provides aesthetic opportunities. With a variety of colors and finishes available, painted steel allows Sandwich Tile to seamlessly integrate into the interior design, contributing to the overall appearance of the building.
The multi-layer structure of the Sandwich Tile , using Galvalume steel or galvanized steel combined with high-quality insulation and aesthetic finishes in painted steel, illustrates the harmony between functionality and design. This combination not only meets the structural and insulation needs of modern construction projects, but also opens up new possibilities for architectural expression.
Advantages of Sandwich Tile
Sandwich Tile stands out in the construction materials market for a series of benefits it brings to projects of all types and scales. Its innovative features offer solutions to both practical and environmental challenges in construction.
