Our commitment to quality, innovation, and long-term performance makes us a smart choice for projects that demand both aesthetics and reliability.

RAIN-SCREEN

Rain-screen means that there is an airspace behind the exterior cladding. Stonetile has a 10mm space. This space allows water, that may enter the wall cavity to drain out again. Potential condensation is allowed to vent out (dry out). This rain-screen space is extremely effective in preventing rot and mold and mildew in exterior walls. Many exterior products do not feature this space. The 2005 Canadian national building code specifies that buildings shall be constructed with rain-screen ­­­­exteriors. A properly functioning rain-screen system functions on the chimney effect principle. Air is allowed to enter at the bottom of the installation and will exit at the top thus drying out any water (condensation). If water droplets migrate into this space they will simply drain out at the bottom.

MECHANICALLY FASTENED, GALVANIZED FASTENERS

Stonetile products feature imbedded galvanized and can therefore simply be screwed onto the wooden sheathing of the building. This system hold all the tiles and molding firmly in place and there is no reliance and glues or mortars. Screw greatly outperform nails and staple which are typically used to fasten materials to exterior walls.

FLEXIBLE GROUT

he joints in a Stonetile installation are filled with Tremco Urethane caulking. This product does not crack like ordinary cementitious mortars nor does it need to be protected from freezing. It is rated as a non combustible material. Please note: the grouting of the joints is merely for appearance purposes and is not an essential part to the rain-screen system. If no joints were filled rainwater would simply run down the exterior wall and the water that was to migrate behind the tiles would simply run down the backside of the tiles and exit at the bottom. This is the beauty of the rain-screen system.

EARTHQUAKE RESISTANT

Seismic forces will likely be absorbed by Stonetile’s unique and patented “crush zone”. The fact that Stonetile is fastened mechanically with screws should give the assurance that this material would survive fairly strong tremors without damage.

RESISTANT TO WET FREEZE/THAW CYCLES

he greatest threat to concrete or other stone, or cementitious materials are wet freeze thaw cycles of high repetition. Concrete will last for thousands of years under water or in the dry sun but we can see the damage on sidewalks in just a few decades. A vertical exterior is usually dry when the temperatures plummet below freezing. If all the flashing is done correctly no wet freeze/thaw damage is possible to Stonetile.

HAIL RESISTANT

n over 27 years of producing and installing Stonetile we have not had a single report that a Stonetile was cracked or broken by hail. We know of hail stricken areas where neighboring exteriors got destroyed by hail and the Stonetile exteriors showed absolutely no damage.

FADE RESISTANT

Stonetile is produced with the finest iron oxide color pigments. Iron oxide pigments in contrast to organic pigments are highly resistant to fading. The color pigments are throughout the mix and are not merely applied to the surface, as is practice with other manufactured stone products.

YEAR-ROUND INSTALLATION

Stonetile is possibly the only manufactured masonry product that can be installed year-round, in freezing temperatures as well as on rainy days. No need to provide expensive heated hoarding for its installation.

MORTAR FREE

Stonetile does not need mortar for its installation, nor does it need a stucco scratch coat. This greatly reduced the mess and the installation costs. You are saving a couple of steps, the application of the wire and the applying of the scratch coat. Normally these additional two steps are required for manufactured stone products.

GREAT FOR DO-IT-YOURSELFERS

We would not suggest that a lay person should attempt to install a Brick, Stucco or a Stone exterior. Stonetile is different. There are several training videos on this website and person without prior experience and who follows the instructions could install a beautiful Stonetile exterior.

UV RESISTANT

Concrete is highly UV resistant similar to real stone. If a piece of Stonetile was placed in a hot dessert it would likely not show any damage from UV exposure for hundreds if not thousands of years. This is in contrast to wood or plastic products which show marked deterioration within a decade or two.

FIRE RESISTANT

Stonetile is made of high density concrete. Concrete does not burn. A wall constructed with Stonetile and with a wooden substrate must not be considered as a fire wall. A fire wall must not contain any flammable materials.

DEVELOPS NATURAL AGING PATINA

Stonetile is not a painted product, there are slight color variations. Even on a single tile or molding you may detect slight variations. This is part of the beauty of Stonetile. This is the natural Stonetile patina. All masonry products will change their appearance slightly over the years and decades. Streaks will develop from water runoff and stones will turn a darker or lighter color. In most cases these changes are not detected. If we look at the historic stone buildings which are hundreds of years old you will see that the color variations are quite noticeable. In our opinion this adds to the beauty of a stone exterior.

EASY TILE REPLACEMENT

It is a well known fact that when damage occurs to an exterior it results in costly repairs. This is due to the fact that the materials often fade over a very short time, or it is not possible to replace a single damaged piece, or products are discontinued. Often the entire wall needs replacing in order to make the repair unnoticeable. A single damaged Stonetile tile or molding can be replaced in the middle of a wall without having to replace the entire wall.

CRUSH ZONE

Stonetile has a patented crush zone. This means microscopic fragments are crushed at the perimeter of each tile, thus prevent damage or cracking to the tiles, when the outside temperatures reach a maximum in the first season thus avoiding a compound expansion of the exterior panels. Stonetile is the only product that has this feature. Other stone or stucco products will crack in vulnerable locations due to these cyclical contracting and expansionary forces.

ENDLESS DESIGN POSSIBILITIES,HUGE PR

Stonetile has the most versatile product line. There are several different tile profiles and several different molding profiles. This allows for exteriors that fit the design of any architectural period from classic to ultra high tech.

SANDED JOINTS

Silica sand is applied to the urethane caulking. This is done to even out small imperfections and to give the joints a realistic mortar appearance. This sand coating will give additional UV protection to the urethane caulking

ENGINEERED PRODUCT

The Stonetile product has been subjected to a battery of rigorous engineering tests in order to obtain the CCMC approvals. The engineer reports are posted on this website. Stucco for example has no engineer reports. It is a product that has grandfathered rights.

HIGH DENSITY CONCRETE

Stonetile is produced with real crushed stone (limestone) and with this material a high density concrete can be achieved. This is in contrast to concretes that are produced with light weight materials. These materials are highly water absorbent. Much higher density and strength can be achieved when concretes are produced with real crushed stone.

HIGH RESALE VALUE

Stonetile ads a dramatic look to the exterior of a home. It is our estimate that a Stonetile exterior increases the value of a home equal or more than what it costs.

BUILT GREEN

Stonetile has been recognized as a Built Green product. The raw materials are locally available (thus low transportation fuel requirements). Production also requires low fuel consumption (no high energy consuming kilns are needed).

GENERAL

What is Stonetile?

Stonetile is a richly crafted exterior wall product consisting of a diverse line of patented concrete tiles and moldings suitable for all types of new and retrofit construction. This line of stunning concrete products ranges from the Ultra Modern, to the traditional classic designs at a very reasonable cost. All tiles and moldings have imbedded metal fasteners that allows this product to be screwed onto the exterior. The joints are filled with urethane caulking which is then coated with silica sand to give the joints a realistic mortar appearance. This joint material will remain flexible.

How long will Stonetile last?

Stonetile is made of high density concrete. Dry or wet concrete will last almost indefinitely. Concrete is not affected by UV. Concrete, and for that matter real stone, will however deteriorate if it is subjected to many wet freezing and thawing cycles. The first Stonetile installations were done over 25 years ago. Upon examination of these projects, one could expect centuries of life as there has been no detectable change. Proper flashing installation and the prevention of ground water soaking into the Stonetile exterior are important steps to ensure that the Stonetile exterior stays unchanged. Our warranty is 10 years on the product. Under normal circumstances, Stonetile can last almost indefinitely if not exposed to unusual wet freeze thaw cycles.

What maintenance is required?

Maintenance is not required.

Will it match with my existing style of my home?

A Stonetile exterior will add beauty to any home, no matter what architectural style it is, that being said the choice of moldings should be in keeping with the architecture of the home. To select baroque moldings, keystones and some other accessories for example would not be the correct choice for a Craftsman or a contemporary style.

Will it match with my existing siding?

Stonetile will add beauty to a home where large partitions of the home feature another siding products such as Stucco, Vinyl, fiber board, brick etc. Great results can be achieved with existing stucco. Moldings and quioning can be installed without removing the stucco. A Stonetile representative will know if an existing product needs to be removed.

What happens when a tile or molding gets damaged?

Call us toll free at 1-800-266-9320 or fill out our service request form here and they will either repair or replace it.

What will my home look like with Stonetile?

We suggest you look at the “Gallery” and get a feel of what your project would look like. You may choose a simply elegant tile exterior with very little moldings or you may choose an exterior with a lot of trim moldings. It will be determined by your personal preference on influenced by your budget.

Do you make cultured stone?

No, the cultured stone is applied with mortar onto a stucco scratch coat, it is produced with light weight aggregate and features multi color shading on the surface. Stonetile has a mortar free installation and the rain-screen system.

Who makes Stonetile and where is the factory?

Stonetile is produced in a Calgary plant by Stonetile (Canada) Ltd.

Where is it sold?

Stonetile is sold though our distributors (see list of distributors) or it is sold directly through Stonetile (Canada) Ltd.

Why are there sometimes rust spots on Stonetile?

Until 2007 Stonetile was produced with concrete sand from local pits.  We found that the impurities, especially Pyrite in this material was increasing dramatically. Even though the concrete quality was excellent, the  fragments of pyrite resulted in unsightly spots.  Stonetile has since solved this issue by sourcing from a new quarry, pure crushed limestone.

What is the Rain-screen system?

Rain-screen is basically a 10mm (or more) airspace directly behind the siding. This airspace allows water that has migrated through the siding to drain down on the backside of the siding and exits at the bottom. This space also allows any condensation to vent out at the top. Rain-screen is the second line of a very effective defense of water entering the building wall cavities. Rain-screen is the solution for preventing rotting of the exterior walls or mold and mildew to appear on the inside of the building. Many other exterior products do not feature the rain-screen system even though the 2005 Canadian national building code requires rain-screen for all new construction.

Can Stonetile be installed over stucco?

We recommend that the stucco is removed so that the tiles and molding can be screwed directly to the wood substrate. If you are doing a small appearance package, such as a few sills under window or some corner quoining  it may be simpler to keep the stucco.

Can Stonetile be installed over Styrofoam?

We have developed a fastening system that allows the product to be installed over Styrofoam. There will be extra installation costs. Please call an exterior envelope engineer to get assurance that potentially devastating condensation issues are avoided with the application of Styrofoam.

Can Stonetile be installed over siding?

Vinyl and aluminum siding must be removed. Wood siding could be left in place provided that a flat surface can be achieved.

Can the whitish stains be removed?

The whitish stains are calcium efflorescence. Efflorescence may occur with all product where cement is used. The stains will come off with the household cleaner CLR. After the cleaning rinse and scrub with a hard nylon brush.

Could I use Stonetile inside?

Yes, but our craftsmen are trained for exterior installations only.

How do I clean Stonetile?

Stonetile does not need cleaning like for example vinyl siding. The reason why vinyl siding gets dirty prematurely is the fact that due to the excessive shrinking and expansion between day and nighttime temperatures. This movement causes static in the siding. It is this static which attracts air born dust. If you have accidental dry paint splatters on your Stonetile, they can be removed with acetone or lacquer thinner on a cotton rag.

Can it be installed in winter?

Yes, wintertime when the vegetation around the house is dormant is the best time of the year to install Stonetile on renovation projects.

How long is the manufacturer’s warranty?

Stonetile has a limited manufacturer’s warranty for 10 years. Stonetile has now been in business for over 25 years and good customer service is behind our success. In contrast, siding applicators traditionally do not offer lasting warranties.

Will Stonetile fade?

Stonetile is produced with iron oxide color pigments which are the most fade resistant color pigments. Color changes over time will likely not be noticeable.

How is Stonetile installed?

Stonetile is installed by our trained craftsmen. Most recently we have a training program for the DIY “do it your-selfers”. There are several videos on our website under “Installation” that teach the know how. We still recommend that the more complicated installations are done by our craftsmen. We firstly do a layout in order to center the product on the wall and set up the necessary scaffolding. We ensure that the product is installed level and that the caulking and sanding is done in a professional manner.

Do you replace tiles or moldings that have rust spots?

No, it is not necessary to replace tiles or moldings which have developed a rust spot (pyrite spot). In our signed contracts we commit to repair these spots with a colored grout.

TECHNICAL

Why is there a patent on Stonetile?

Stonetile has uniquely tapered edges. When expansion happens on hot days, the product expands slightly. (concrete expansion is minimal when compared to plastics or metal) nevertheless this expansion is absorbed in the tapered edges and any thermal cracking is prevented. In contrast other masonry products need unsightly expansion joints and even with expansion joints cracks often develop.

Can Stonetile be painted?

Yes Stonetile can be painted with a good quality acrylic latex paint. Due to the fact that Stonetile has the venting and draining rain-screen system paint will adhere perfectly and not peel on vertical walls.

Do all the tiles have to be fastened to the studs?

No Stonetile gets screwed into the plywood or OSB sheathing with 1” #8 screws.

What is Stonetile made of?

Stonetile is made of high density concrete of which the main ingredient is pure crushed limestone. The tiles and the moldings have embedded galvanized metal fasteners.

Are the joints completely water tight?

We make an attempt to seal all joints with the urethane caulking but our primary focus is a great appearance. If traces of water end up behind the tiles it will simply runs down the backside of the tiles and exits at the bottom and there is no harm done. If for example the joint filling was not done, the rain-screen system would still be fully functional and water could not enter the wall cavity.

How heavy is Stonetile?

Stonetile is about the same weight as a good quality stucco exterior and no additional support is required.

Should the brick always be removed?

Architecturally, brick and Stonetile is quite complementary although the earth tone color palette of Stonetile may not be complementary to the bright brick colors. If brick and Stonetile are used together, painting the brick may be a solution.

Is Stonetile treated with a sealer?

No sealer is sprayed on the surface of the tile. Sealers have a limited lifespan. Our high density concrete is the best protection against UV light damage.  Sealers as well as many other products will be damaged or will disintegrate over the years.

How do I become a Stonetile craftsman?

Contact the distribution directly you would ideally like to work with, and email a copy of your resume attention to the Construction Manager. The duration of your training will depend of how much general construction experience you have already.
