Frequently Asked Questions at 3R Tiles

General Information

What makes 3R Tiles distinctive in architectural creativity ?

Aside from the quality of the material and the manufacturing factory process, Tuiles 3R wanted to offer its customers the ability to customize the architecture of any building by combining multiple shapes, patterns of poses and colours (see Special projects section).

In addition to reproduce with fidelity the metal roofs of old style, Tuiles 3R products allow unique contemporary design creations, without compromising the technical requirements of strength and sealing.

It is thus possible to blend several models of tiles on a same building by varying shades of colors, geometric shapes, dimensions of identical parts as well as the installation guidelines.

Exterior wall (wall covering, siding, attic) tiles may very well harmonize with other materials such as wood, brick, stone and glass.

These wall tiles can also be installed on walls or interior architectural structures to create a bold and unique design.

How PVDF Kynar 500® finish provides superior performance on metal roof and siding ?

Tuiles 3R offers you products in steel and aluminum including finish treatment that provides superior durability and optimal resistance to cleaning of graffiti on sidings.

KYNAR 500® and HYLAR 5000® surface finishing products are currently the best treatment products for the siding and metal roof in aluminium and steel. All products from Atas International, Inc., are treated with KYNAR 500® or HYLAR 5000®.

Comparative tests with other finishing products have shown that the KYNAR 500® / HYLAR® 5000 achieve better results at the level of resistance to UV rays, abrasion, fading, chemicals, solvents. This treatment also allows to clean stains and graffiti without leaving visible traces or damage the coating.

KYNAR 500® and HYLAR 5000® are compounds of polyvinylidene fluoride (PVDF). PVDF is also used and tested in multiple industrial applications where the product is exposed to extreme variations in temperature as well as multiple chemical corrosive elements.

The comparative strength of the surface treatment of PVDF Kynar 500® was assessed in laboratory tests. Among the results, Kynar 500® has much better resisted testing solvent cleaning compared to acrylic based products.


The material for roofing and exterior wall (siding, attic) is mainly composed of four elements: the gauge steel sheet 26, a galvanized metallic coating (zinc or zinc-al alloy various treatments of adhesion of products, a primer coat and a top coat (color). Tiles 3R manufactures all its roofing tiles and exterior wall with prepainted (Perspecta) gauge steel 26 or others, as well as aluminum (Kynar 500 PVDF) of varying thicknesses (.030, .040, .050).

These processes improve resistance to corrosion, particularly against surface scratches and at the level of the curvatures of fold.

Metal roof tiles

What return on investments could you expect with a metal roofing ?

The renovation of your roof is a major work that provides one of the best return on investment. According to the Institute of Canadian evaluators, average performance lies between 50% and 80% recovery of the investment at resale. As this statistic includes the asphalt shingle, whose life is quite limited, it is clear that metal roofing will provide superior performance and that this performance will continue long after laying. The installation of metal tiles on an outside wall is also an excellent sustainable investment (siding, attic).

An asphalt shingle roof will have a limited lifetime and you will probably need to change it at least once, if not more. The metal roof will not be changed and lasting strength and appearance will allow you to retrieve an important part of your investment on a sale.

What features heritage roofing tiles (Standing Seam, Canadian style, Wood casing tile) ?

Tuiles 3R’s expertise is also in the manufacture of traditional metal roofing tiles according to the original techniques which are often required by urban planning and heritage preservation committees in some municipalities.

Standing Seam tile on roofing

Not to be confused with some profiles sold in store, the Standing Seam tile is not a profile but indeed a tile. The superposition of the tiles along the slope, combined with pinching of the joint system provides a solidity and greater expansion flexibility during changes of temperature (see Metal roofing tiles section)

Canadian style tile

The installation of the Canadian style tiles to the roof dates from the late 16th century. This type of roof then known great popularity between the years 1750 to 1850. This technique was developed to solve the problems of resistance of the welded plates from older designs.

The installation of a Canadian style roof requires a slope of at least 15 degrees. Today, the use of waterproof membranes and sealants improve the quality of these roofs. Otherwise, it can be installed on the attic (Gables) and vertical walls. Over time, the installation process is also improved. Contemporary pattern of poses, the installation of the tiles on the roof angle prevents ingress of water at the level of the seals. Furthermore, the addition of a deck’s departure provides a better seal at the base of the slope (see Metal roofing tiles section).

Casing style tile

This very old roofing technique would have been imported from Europe around 1800. Several of these roofs are still existing today, due to the high efficiency of the installation process. We find today different industrial products that mimic the pattern of the tile to stick, but their assembly does not reach the aesthetic quality and the degree of effectiveness of the original technique.

The installation of a Casing tile roof requires a slope of at least 15 degrees. Today, the use of waterproof membranes and sealants improve the quality of these roofs. At Tuiles 3R, we recommend the use of the baton trapezoid-shaped wood, because its closer base provides a space to absorb the expansion of the metal, thereby preventing its deformation (see Metal roofing tiles section).

What is the advantage of patented Dutch Seam fastener ?

One of the problems related to the installation of metal (profile) panels on roofs and sidings is buckling. When the temperature changes, the metal panel expands and shrinks, which is normal. Most of the panels are screwed directly on the bridging of the roof along their length. For this reason, dilation invariably causes buckling, since the panel is fixed. The deformation is apparent and it promotes the formation of micro-cracks in the finish treatment. This problem accelerates ageing of the roof and degrades its appearance.

To prevent this problem, Tuiles 3R offers the Dutch Seam panel, which is equipped with a patented fasteners hidden sliding system. Through this mechanism, panel slides into the attachment system mounted on the roof or siding, allowing the panel to expand and contract freely during changes of temperature. Dutch Seam is available in steel and aluminum and its basis of PVDF (Kynar 500) surface treatment offers the best durability on the market. Dutch Seam can be installed on roofs as on sidings and is available in 40 colours.
Patented fasteners for absorption of the expansion of the panels (see Metal roofing tiles section).

What makes metal roof far beyond asphalt shingle ?

The metal roofing covered most of our houses before World War II. Our most beautiful ancestral homes and our heritage churches are often covered with metallic roofings. During the war, the metal was requisitioned. The asphalt shingles, more economical, came in the following decades. However, its lifespan is much shorter, making it a product of temporary and more polluting facility.

The shingles are not or little recycled. Sensitive to UV light, they emit solvents in air, in particular under exposure to the sun. Most often black, they contribute to heat islands, i.e. the increase in temperatures in urban areas.

On the other hand, steel is a recyclable material at the end of life, which will be very long.

The Tuiles 3R metal roofing tiles have an interlocking system that prevents buckling of the roof by expansion and contraction during temperature changes. The system allows the tiles to move without buckling or pull on the screws. Your roof will retain its consistency and its seal despite the years (see Metal roofing tiles section)

How plastic film improves metal tile and panel protection ?

Tuiles 3R pays particular attention to the packaging of its products for its customers and construction site delivery. In our factory, each tile is packaged individually. The tiles are then arranged in several boxes in order to facilitate their handling on site as well as their protection.

Each metal panel is covered with plastic film to protect the surface finish to the stage of the installation.

Metal siding tiles

What does 3R Tiles “in relief effect” siding tile means ?

Tiles 3R offers two distinct styles of wall tiles (siding):

1. Siding tile with relief effect

The manufacture process of this tile gives it a more pronounced effect of relief on siding.

Tuile relief carrée 1

2. Siding tile without relief effect

The manufacture process of this tile gives it an effect without relief.

* Technically, all 3R roofing tiles can be installed as a siding. Their production being planned to resist the demands of roofs, the vertical installation presents no problem. However, Tuiles 3R offers tiles whose manufacture is planned specifically for wall installation (siding, attic). Ask our representatives for more information.

What is the distinctive choice 3R Tiles offers in perforated panels ?

Tuiles 3R offers you the widest choice of metal panels perforated on the market. Now, you are no longer limited in selection of products perforated for your architectural projects. The panels perforated of Atas International are grade aluminum. 032, 040 and .050. They are available in ten of configurations and six patterns of standard perforations (transparency of 23% to 51%). Perforation tailor-made schemes can also be manufactured. Factory aluminum foil is first perforated, then formed and finally processed and painted with PVDF KYNAR 500® or HYLAR 5000®. The color covers the inside of the walls of the holes. The back of the panel is treated and painted in primer or the same color as the front, on request.

All these configurations of panels are available in different patterns of holes (see Metal siding tiles section).
