Technical Features

Tectal's roofs are designed to be extremely resistant to the elements and in several important aspects they are environmentally friendly.

Sturdy tiles

A key factor in the product's durability is tile thickness, which provides the essential mechanical properties for creating a waterproof and durable roof: Tectal's tiles are 50 thousandths of an inch thick, about double the value normally used in roofing sheet metal. Sturdiness is thus increased eightfold with respect to the latter.



Totally waterproof

Resistance to water ingress is assured by a large tile overlap and close contact in the overlap area (because of the stiffness of the tiles)

and an absolutely integral underlying membrane (Soprema Lastobond Shield).

Resistant to extreme winds

Wind resistance is well over 200 mph (tested at NRC's facilities in Ottawa).  In fact, wind uplift resistance is about double that corresponding to the UL 580 Class 90 rating.

Thick architectural anodization

Anodization thickness is 20 microns vs a North American standard architectural practice of 18 microns. Surface aspect permanence is thus assured for a considerable length of time.

Colors resistant to UV deterioration

Color is obtained by differential diffusion or interference of light in the anodic layer. Pigments are not used because they are inherently subject to deterioration by ultraviolet radiation from the sun.

Environmentally friendly

Tectal's roofs present a particularly interesting case of recyclability and environmental friendliness.  Anodization is essentially performed at room temperature, does not release volatile by-products and is increasingly practiced at zero effluent. Furthermore, as the finish is completely mineral the scrap from both process and installation is easily recycled since it can be remelted without obnoxious volatile combustion products. Likewise, some future generation will eventually recycle the entire roof cover at full metal value.  Finally, Tectal roofs provide a layer of air between the tile undersurface and the white underlying membrane. The building is cooler in the summer, for increased comfort or valuable energy savings.
