Interior vs Exterior Tile: Continuity In & Out

When purchasing tile, it is important to understand the difference between indoor and outdoor tile. Porcelain tile offers functionality with a wide range of design, making it an ideal option for both indoor and outdoor projects, but what is the difference between interior and exterior porcelain tile? Here are some of the key differences to keep in mind when choosing tile for your home, and how to create a smooth transition from interior to exterior.

Thickness

The key difference that sets an outdoor tile apart from an indoor tile is it’s thickness. Interior porcelain tile typically have a thickness of 9-10mm, whereas exterior can reach a thickness of 20mm or more. Why is this difference so important? A thicker tile provides a strong, long-lasting surface, capable of withstanding heavy foot traffic, weather conditions, and in some cases vehicles and other heavy-duty outdoor equipment. A thinner tile that is not built to withstand these conditions, can result in damage and a short lifespan.

Surface

Creating a slip resistant environment is especially important for outdoor spaces due to weather elements and high traffic. Tile designed for outdoor installation will be un-glazed giving it a organic finished look, whereas a glazed tile will provide a glossy finish, beautiful for interiors, but creates a slippery surface when exposed to water. A textured tile provides further slip resistance, allowing for a natural grip on the surface.

Density

Baked at high temperatures, outdoor tile is an extremely dense material. This density allows the tile to withstand sudden temperature changes, direct sunlight, frost, and other environmental elements. This density also prevents mold and mildew from permeating, making for easy cleaning with minimal maintenance.

Keeping these differences in mind, how do you create a smooth transition from interior to exterior? Ultimately, using an indoor tile in an exterior space will result in damaged, faded tile and an overall short lifespan. The best way to ensure both a functional, and seamless transition between interior and exterior spaces, is opting for a tile that offers both interior and exterior thickness and finish options. This guarantees ideal function in both spaces, while maintaining a smooth, cohesive transition.
