Fiberglass mesh

In the construction industry, where aesthetics, energy efficiency, and durability go hand in hand, EIFS (Exterior Insulation and Finish System) has emerged as a preferred façade solution—especially in the UAE and other hot climate regions. EIFS offers multiple benefits: lightweight construction, thermal insulation, and design flexibility. But there’s a crucial component that often goes unnoticed—alkaline-resistant fiberglass mesh.

At IBeam Construction Products, we supply high-quality EIFS mesh engineered to meet the specific demands of external wall insulation systems. In this blog, we’ll explore why this mesh is vital, and how it directly impacts the success and longevity of EIFS installations.

What is Alkaline-Resistant Fiberglass Mesh?

Fiberglass mesh is a woven fabric made from glass fibers, typically coated with a protective material to enhance performance. In EIFS systems, it acts as a reinforcement layer within the base coat, preventing cracking and strengthening the façade.

Alkaline-resistant mesh is specifically treated to resist degradation from the highly alkaline nature of cement-based products used in base coats. This resistance is critical for maintaining adhesion and ensuring long-term durability.

Why Alkali Resistance Matters in EIFS Systems

Cement, plaster, and other finishing materials used in EIFS are alkaline by nature. Without proper resistance, standard fiberglass mesh can deteriorate over time, leading to:

• Hairline cracks on the façade
• Compromised adhesion between insulation layers
• Premature failure of the finish system due to moisture penetration or UV exposure

Using alkaline-resistant mesh significantly reduces these risks, making the façade more resilient under UAE’s extreme heat, humidity, and sandstorm conditions.

How IBeam’s Mesh Stands Out

At IBEAM, we understand that not all fiberglass meshes are created equal. Our EIFS mesh is:

• Alkaline-resistant for superior durability in cement-rich environments
• High tensile strength to resist expansion and contraction stress
• Uniformly woven for consistent coverage and easy application
• Available in multiple weights (e.g., 145g/m², 160g/m²) and roll sizes

We supply rolls tailored to project needs, ensuring ease of installation and compliance with regional construction standards.

Applications in the UAE Construction Market

Our EIFS mesh is widely used in:

• Façade insulation of high-rise and commercial buildings
• Residential villas with decorative plaster finishes
• Renovation and retrofit insulation projects

Given the region’s push for energy-efficient and LEED-compliant buildings, the demand for reliable EIFS materials continues to grow.

EIFS System materials

EIFS systems are only as strong as the materials behind them. Choosing a high-quality, alkaline-resistant fiberglass mesh is essential for achieving a long-lasting, crack-free, and energy-efficient façade. At IBeam, we supply mesh that meets global standards and stands up to the UAE’s toughest conditions.
