Silicone in the construction sector

Silicone is a key material in the construction sector due to its versatility, durability, and ability to adapt to the most innovative designs.

This material is used in a wide variety of applications, both in exteriors and interiors, including interior design elements, lighting, and decoration. Its excellent resistance to heat, UV rays, abrasion, deformation, and aging guarantees a long service life, helping to maintain the structural integrity of the building while offering effective insulation against pollution, dust, and water. Additionally, its ability to absorb stresses and vibrations reinforces the stability of the structures.

At Merefsa, we design, test, and customize each project to meet the specific needs of our customers, ensuring tailored solutions with the highest quality standards.

Silicone Strengths


Mechanical: Silicone offers high resistance to deformation, making it ideal for sealing and insulation against dust and weather agents. It effectively absorbs vibrations and structural movements. Fluorinated silicone stands out for its resistance to high temperatures and corrosion.

Thermal: It withstands temperatures from -60 °C to +300 °C, making it perfect for environments with continuous sun exposure and extreme weather conditions.

Chemical: Its ability to adapt to different hardness levels, colors, and transparency allows for customized solutions in façades and interior design.

Where is it used?


Silicone is mainly used in exteriors, combined with materials like steel, glass, and plastic, to ensure effective sealing and protect the interior of the building from pollution, temperature variations, vibrations, water, and dust.

In interiors, it is used in design elements, lighting, pipes, and air conditioning systems, providing insulation and resistance.

Applications: Sealing doors and windows, glazing profiles, hoses, lighting systems, air conditioning, anti-vibration blocks, filling empty spaces, ventilation joints, and fluid pipes, among others.
