Window Replacement Companies Praise Vanguard Windows 

When you choose a top-of-the-line window replacement company, they will be able to offer you a brand of windows called Vanguard.  These windows truly are in the vanguard of window manufacturing technology. Denver, CO can be seen here.

Patented Design

Vanguard Windows are some of the strongest windows available in the Denver area.  They are also energy-efficient and maintenance-free.  To squeeze all these great qualities into one window, Vanguard patented material and a process called FiberCore.  FiberCore is a combination of polyvinyl chloride (PVC) with Fiberglass.

The inside core of the vinyl window frame is pultruded fiberglass.  Pultruded is the opposite of extruded – it just means the fiberglass is pulled through the vinyl sleeve rather than forced through by being pushed through the vinyl sleeve.  This technologically advanced process makes an extremely strong product stronger than any other window frame available.

This pultruded fiberglass is about as strong a material as can be found.  Plus, it makes the windows energy efficient. It’s no wonder the Vanguard Window Company patented this window.

FiberCore by Vanguard

The corners of FiberCore window frames are fusion welded together.  This means they won’t ever leak over time because they are not screwed together like other windows.
