Outdoor Fireplace Lintel: Best Designs & Install Tips for 2023

Transform your outdoor living space into a cozy, inviting oasis with an elegantly designed outdoor fireplace. The optimal way to define and stylize your fireplace is through a well-crafted lintel, an essential part that safely supports the structure of your firebox. Let's delve into the world of outdoor fireplace lintels, their types, materials, and installation to help you make an informed decision for your perfect outdoor haven.

Outdoor fireplace lintels play a pivotal role in maintaining the integrity of your fireplace, providing essential support to the weight of the masonry above the firebox. They also serve as a stylistic element, infusing your outdoor space with character and charm. But with so many types and materials available, selecting the right lintel can feel overwhelming.

Understanding Outdoor Fireplace Lintel Types

The type of lintel you choose will depend on your fireplace's design, intended use, and the overall aesthetic of your outdoor space. Here are two primary types of outdoor fireplace lintels to consider:

Flue-Less Lintels

Flue-less lintels are ideal for outdoor fireplaces that don't require a chimney or flue. They provide adequate support for the masonry and wood-burning firebox, creating a rustic, traditional look. Typically constructed from concrete or stone, flue-less lintels are cost-effective and easy to install.

Consider these lintels for your patio or outdoor kitchen project where you want a classic, no-frills fireplace design. They complement various outdoor materials like brick, stone, or concrete, offering a robust, durable choice for your firebox's support.

Flue Lintels

Flue lintels, on the other hand, are designed for fireplaces that have a chimney or flue system. They come in different sizes to accommodate varying flue diameters and should always be installed by trained professionals to ensure proper fit and safety.

Flue lintels are perfect for wood-burning or gas fireplaces with chimneys. They provide additional safety by containing the fire within the designated area and allowing proper ventilation. Available in various materials like cast iron, stainless steel, or composite materials, flue lintels add a modern, sleek touch to your outdoor living space.

Evaluating Outdoor Fireplace Lintel Materials

Materials play a significant role in the durability, aesthetic appeal, and functionality of your outdoor fireplace lintel. Here are some popular materials to consider:

Concrete

Concrete lintels are cost-effective, durable, and easy to install. They are available in a wide range of colors and styles, making them versatile for various outdoor design themes. However, concrete lintels are heavy and may require additional support during installation.

To extend the lifespan of concrete lintels, seal them with a concrete sealant to protect against water damage and staining. This will help maintain their appearance and functionality for years to come.

Stone

Stone lintels add a touch of luxury and durability to your outdoor fireplace. Available in natural stones like granite, limestone, or sandstone, stone lintels provide excellent insulation and can withstand extreme temperatures. Despite their elegance, stone lintels are relatively lightweight, making them easy to handle and install.

To preserve the natural beauty of stone lintels, apply a sealant after installation to prevent moisture absorption and staining. This will also help maintain their color and texture over time.

Stainless Steel

Stainless steel lintels offer exceptional durability and corrosion resistance, making them perfect for coastal or high-humidity environments. They are lightweight, easy to install, and available in various sizes to fit different flue diameters.

Although more expensive than other materials, stainless steel lintels provide a modern, sleek look that complements various outdoor design styles. They require minimal maintenance, making them a low-effort, long-lasting choice for your outdoor fireplace.

Installing Outdoor Fireplace Lintels: A Brief Guide

Proper installation is crucial for the safety and longevity of your outdoor fireplace lintel. Before you begin, ensure you have the appropriate tools and knowledge or hire a professional for a smooth, secure installation.

Flue-Less Lintel Installation

1. Prepare the firebox by ensuring the dimensions match the lintel's size. 2. Apply fire-resistant mortar or adhesive to the lintel's underside and place it evenly across the firebox opening. 3. Allow the mortar or adhesive to set according to the manufacturer's instructions. 4. Apply a thin layer of mortar or adhesive to the lintel's top surface and begin laying the masonry above it.

It's essential to use non-combustible materials for the masonry above the lintel to prevent fire risks. Always follow local building codes and obtain necessary permits before installing an outdoor fireplace.

Flue Lintel Installation

1. Measure and cut the flue to the appropriate size, ensuring a proper fit with the lintel. 2. Apply fire-resistant mortar or adhesive to the lintel's underside and secure it onto the firebox's back wall. 3. Allow the mortar or adhesive to set according to the manufacturer's instructions. 4. Insert the flue into the lintel, ensuring it's securely supported and centered. 5. Apply a thin layer of mortar or adhesive to the lintel's top surface and begin laying the masonry above it.

Flue lintel installation can be more complex, as it requires precise measurements and proper alignment with the flue. It's recommended to hire a professional for a safe, secure, and aesthetically pleasing result.

Embracing the joy of outdoor living begins with creating a comfortable, inviting oasis tailored to your preferences. An outdoor fireplace with a beautifully crafted lintel adds warmth, ambiance, and functional elegance to your space. By understanding the types, materials, and installation techniques for outdoor fireplace lintels, you can make an informed decision that enhances your outdoor living experience.
