Frequently asked questions

Why is tile the healthy choice?

Ceramic and porcelain tile is made from natural ingredients and is free from toxic chemicals that can make you sick. Tile is hypoallergenic, naturally resistant to dust and other harmful pollutants known to cause a variety of health issues, which makes it a good choice if you suffer from allergies or asthma.

Tile is impervious, meaning it is inhospitable to dust mites, bacteria, fungi, mould and other irritants. It is inherently inorganic and emits zero VOCs — the harmful gases emitted by virtually all other types of flooring, which can cause headaches, nausea and nose, eye and throat irritation, and are a leading cause of sick building syndrome.

Tile is also a solid material, so it does not contain the binders common to other flooring and wall surfaces, such as formaldehyde. It is free from PVC, a resin used elsewhere to improve mechanical flexibility and heat stability; PVC contains phthalates and organotin, both regularly a subject of concern among health experts.

Why is tile the green choice?

Tile is a sustainable building material, certified green. No other flooring or wall covering compares to tile for longevity — installed correctly, tile lasts for many generations. Combined with zero-waste manufacturing, that makes it the most eco-friendly choice for flooring or wall coverings.

Ceramic tile is plastic-free and completely recyclable, and there are many tile options made from recycled materials.

Tile is energy efficient. Its inherent thermal mass reduces peak heating and cooling, which moderates temperature swings in your home — less work for your HVAC system and more energy savings for you.

Tile manufacturers have the lowest carbon footprint of any flooring choice. They typically use materials found within 500 miles of their manufacturing facilities, dramatically reducing the energy and emissions of long-distance shipping.

Why is tile the classic choice?

Over the centuries, tile has represented the perfect union of art and architecture. The richness of tile adorns our greatest buildings and historical icons. Whether you are looking for a durable surface for your flooring or something with a wow factor, tile can and should fulfil both.

Is tile waterproof?

Short answer: no. This matters when you are choosing a contractor to build and tile your shower or bathtub surround.

Your shower will have an average of 1,100 inches of water run through it per year. For comparison, the average rainfall in Seattle, Washington is 36 inches per year. Make sure whoever installs your new shower tile has a plan for waterproofing before the tile goes on.

Types of tile

Porcelain tile
Impervious — water absorption of 0.5% or less. A great choice for any application, easy to maintain and very durable.
Ceramic tile
Fired clay like porcelain, but not fired as hot or as long, making it a softer product. Ceramic absorbs water at a much higher rate, which makes it a poor choice for most outdoor applications.
Mosaic tile
Tiles with a facial area of less than 9 square inches, typically mounted on sheets or strips with other mosaic tiles.
Encaustic tile
Tile decorated with coloured clays, inlaid and fired. Often referred to as cement tile.
Marble tile
Marble that has been cut into tile sizes.
Gauged porcelain panels & slabs
Large-format tile gauged to a specific thickness, often only half the thickness of standard tile, and up to 63" x 126".
Natural stone
Tiles cut from naturally occurring material — travertine, marble and similar.
Feature tile
Tile used strictly to make a statement and express your artistic taste. 3D tile, metallic tile and stone-look tile are a few of the options.

Tile terms

The words that turn up in quotes and spec sheets, in plain English.

Brick joint / running bond
A tile installation with each row offset, typically by half its length. If the side to be offset is greater than 15", a maximum offset of one third is recommended.
Bullnose
Trim tile with a radius on one edge, used for finishing an edge.
Backerboard
An underlayment material used as a substrate for tile. Some backer boards are waterproof; others need to be waterproofed for proper shower construction.
Grout
The material used for filling tile joints.
Honed
A satin surface with little or no gloss.
Lippage
A detectable change in elevation between the edges of tiles sharing the same grout joint.
Membrane
An underlayment material, usually a sheet or a trowelable liquid, applied to the substrate before tile installation — for example crack isolation membranes and waterproof membranes.
Thinset mortar
A blend of cement, sand and additional compounds that improve adhesion and add strength.
Rectified tile
A tile with all edges mechanically finished to achieve a more precise facial dimension.
Trim
Various shapes of bases, caps, corners, mouldings and angles used to finish or trim tile.
