Heat-strengthened and tempered glass

We also offer a full line of heat-strengthened and tempered glass products. When tempered glass shatters, it disintegrates into small pieces, reducing the risk of personal injury. Often, bus shelters are made using tempered glasses. Once tempered, the glass is four times stronger than annealed glass.

Heat-strengthened glass is twice as strong as annealed glass, with significantly greater resistance to thermal loads when compared to annealed glass of equal thickness.

By combining and layering tempered and laminated glasses, we can provide a bulletproof glass product. The multiple coatings of tempered and laminated glasses form a fully sealed "wall."

Sealed units

Sealed units are among the best performers in the marketplace. We manufacture sealed units that are composed of two glass panels separated by a metal spacer system—creating an interior space filled with an inert, nonconductive gas such as argon. The addition of this gas layer improves the insulating value of the unit and makes it more energy-efficient.

Gas-filled units are finished with a primary seal of polyisobutylene to provide maximum protection against moisture vapor transmission. This secure seal has proven to be an excellent barrier against gas leakage—although Entreprises Doco uses only gases that are odorless, colorless, and harmless. A secondary seal is applied on the outer surface of the spacer system to provide strength in bonding the glass and metal components. We use a seal made with either urethane or silicone.

Obviously, the metal spacer can be made from steel, aluminum, or other products with insulating properties, which Multiver refers to as "spacers with low conductibility." We uses a wide range of these products, after ensuring their performance capabilities.

Sealed units meet CSA standards (CAN/CGSB 12.8), and the company's quality assurance program meets the requirements of IGMA (Insulating Glass Manufacturers Alliance), as well as the organization's certification program.

Clear glass

If customers desire the traditional look of glass—combined with the clarity and light transmittance of skylights - we also can provide clear glass products.

Soft-coat reflective glass

High-performance soft-coat reflective glasses are used in a wide range of architectural projects. This type of glass is popular because of its longevity and durability when compared to other glasses. In addition, it has superior aesthetic properties, allowing architects to achieve continuity in "curtain wall" applications.

High-performance soft-coat reflective glass is available in tempered, heat-strengthened, annealed, or tinted options to meet architects' exact needs and specifications. Metal coatings, including silver and titanium, are applied in thin layers within a vacuum chamber, a process that produces the best reflective qualities.

Depending on the thickness and type of metal layers applied, Entreprises Doco can supply a more or less pronounced "mirror" effect—and also can influence such performance characteristics as visible light transmittance, shading co-efficient, and solar transmittance. Multiver's custom solutions allow customers to control the brightness of interior environments, as well as the use of air conditioning.

Pyrolytic reflective glass

Architects can also choose from a variety of pyrolytic reflective glass products. In the pyrolytic manufacturing process, different metals are fused with liquid glass, making the coating an integral part of the product. Pyrolytic reflective glass can be tempered to enhance its strength and resistance.

High-performance low-emissivity glass

If energy savings are a priority, "Econover" glass products are ideal. These high-performance low-emissivity glasses feature a thin metallic layer that reflects infrared light. The low-emissivity coating reflects furnace heat back into the room during winter months—a "boomerang effect" that reduces heating costs during winter months.

High-performance low-emissivity glasses also minimize solar energy transmittance during summer months, reducing the use of air conditioning. In addition, the low-emissivity coating filters out ultraviolet rays, helping to protect furniture, carpeting, and artwork from sun exposure.

Tinted glass

We also offer tinted glass products, manufactured by mixing metallic oxides into the melted glass. The most popular tint colors are green, bronze, gray, and blue. Tinted glasses reduce air conditioning costs, while also enhancing aesthetic value.

Glass design options

For those customers who want to "dress up" their windows, we can introduce colored grids or other designs into its sealed units. These designs are available in a wide variety of shapes and colors.
