The Anatomy of Our Windows

Not all vinyl replacement windows are the same. Take a closer look at the premium components that should be included in any window you are looking at for your home.

Window Cut

Super Spacer and Hot-melt Butyl

Centennial uses two different products to separate and seal our multi-pane glazed units. Each serves as a complementary spacer and seal, creating best-in-class sealed glass units.

1. Super Spacer serves as the primary spacer and the secondary seal. It is a non-metallic silicone rubber strip that separates the two pieces of glass in a double glazed sealed unit.

2. Hot-melt butyl serves as the primary seal and the secondary spacer for the multi-glazed units and creates an impermeable seal, keeping the argon gas inside.

LOW "E" Glass

Low Emissivity glass is an invisible, metallic coating on one of the glass surfaces. Centennial glass has the Low E coating on the inside of the inside pane of glass, known as surface #3.

Not all Low E coatings are the same. Centennial Low E coating is a hard-coat, the coating is applied when the glass is still at its molten state creating a much more durable coating compared to soft-coat which is sprayed on after the glass has cooled.

Low E coating is a reflector that allows heat to stay in the house in the winter and out in the summer. It also cuts down on penetration of ultra-violet rays.

Often touted as one of the most important energy efficiency breakthroughs for windows, Low E coatings dramatically reduce heating and cooling in homes, saving money and making homes more comfortable. As well, Low E coatings reduce fading on flooring and furniture from the sun.

Argon Gas

Argon is an inert gas (colourless & odourless) that comes up from the ground, natural in the air that we breathe, and is used in the manufacturing of fluorescent light bulbs.

Because argon is heavier than air, it acts as an effective insulator between the glass in double glazed sealed units (Krypton is used in triple glazed units) and leaves the glass transparent.

Fusion welded corners

All corners on Centennial windows are fusion welded so that they essentially become one piece. Interior and exterior channels are welded together ensuring optimum performance and durability of the frames and sashes.

The joints are not only stronger than mechanical joints (screws, nuts and bolts and glue), but because they become one piece, the weather cannot pass through the joints eliminating drafts, leaks and interior corrosion.

UPVC Frame and Sashes

UPVC or Unplasticized Polyvinyl Chloride is the primary building material used in Centennial windows' frames and sashes and is the premium vinyl available for window manufacture.

UPVC is a non-corrosive material that won't oxidate, making it virtually maintenance free.

UPVC is a low-conductive material which dramatically improves window energy efficiency, providing comfort in the home and lower heating and cooling costs.

Foam-Filled Frames

Centennial frames and sashes are filled with a safe polyurethane foam (similar to the foam found in picnic coolers).

Foam filling frames and sashes adds three very important advantages to the window:

1. Improved insulation - reduced heating / cooling costs

2. Improved sound insulation - reduced outside noise in your home

3. Increased structural strength - reduced chance that the window will bend or warp from house settling and outside forces like weather
