The Crucial Role of Lintels: A Must-Have for Window Installations According to Fairview Windows and FENSA

When it comes to installing new windows, homeowners often focus on the aesthetics and energy efficiency of the windows themselves. However, an equally important but sometimes overlooked component of window installations is the lintel. At Fairview Windows, we believe that lintels play a vital role in ensuring the structural integrity and longevity of your windows. In fact, the Fenestration Self-Assessment Scheme (FENSA) strongly advocates for the inclusion of lintels in window installations. In this blog post, we will explore why lintels are crucial and how they contribute to the overall performance of your windows.

What are Lintels?

Lintels are horizontal structural elements typically made of steel, concrete, or other sturdy materials. They are installed above openings like doors and windows to support the load from the structure above, ensuring that the weight is distributed evenly. In the context of window installations, lintels are essential for preventing structural damage and maintaining the stability of the building.

The Importance of Lintels According to Fairview Windows:

  1. Structural Support: Lintels provide crucial structural support by redistributing the load from above the window opening. Without lintels, the weight of the wall or roof can cause the window frame to sag over time, leading to misalignments, cracks, and other structural issues.
  2. Preventing Window Deformation: Windows without lintels are more prone to deformation and misalignment. Over time, the lack of proper support can cause the window frame to warp, affecting its functionality and compromising the overall integrity of the installation.
  3. Longevity of Windows: Lintels play a key role in preserving the longevity of your windows. By distributing the load effectively, lintels help prevent premature wear and tear on the window frames and surrounding walls, ensuring that your windows remain functional for years to come.

FENSA's Perspective on Lintels:

FENSA, the leading authority on window and door installations, emphasizes the importance of proper installation practices. According to FENSA regulations, lintels are considered a fundamental part of window installations. FENSA-approved installers, like Fairview Windows, adhere to these guidelines to guarantee that every window installation meets the highest standards of safety and durability.


In conclusion, the inclusion of lintels in window installations is not just a recommendation; it’s a crucial element for ensuring the structural integrity and longevity of your windows. Fairview Windows, in alignment with FENSA regulations, advocates for the use of lintels to provide the necessary support and stability that your windows need. When investing in new windows, don’t overlook the importance of lintels for a secure and long-lasting installation.
