Interstate Model 6800 Windows

Our top-of-the-line vinyl model offers aesthetics, performance and versatility, everything you want in a window.

The 6400 has it all from lifetime glass breakage, high definition wood-like interiors, one-handed fusion lock tilt, and unlimited colors.  This model also offers standard features that can resemble the look of real wood windows.  With the fusion lock option and the routed lift handle added to the cherry interior, the beauty of wood windows now can be accomplished.

This line also offers all configurations and designs from a complimentary sliding window that swings in for easy cleaning, followed by a full line of casement, awning, shapes and picture windows enhanced by a fully upgraded patio door to make the project complete.

Interstate CompositeWood® Windows

CompositWood blends the elegant appearance of a true wood window with the maintenance freedom of vinyl, the strength of metal, cutting edge energy saving and operational features into a beautiful and durable window system.  Frames and sashes are made from a proprietary mix of specialty polymer and acrylic resins, creating an “engineered composite”, super tough, solid core material.  A permanent color surface technology called “SuperCap™” is fused to the core materials during the extrusion process.  The result is an extremely durable, weatherable and fade resistant product that is far superior to other window framing materials.

CompositWood provides the warmth of a finely milled wood window without the problems associated with wood.

Alside Sheffield Fusion-Welded Windows

The superior performance of Sheffield® Windows starts with innovation.  Every precision-engineered component contributes to superior energy savings.  The multi-chamber design helps trap dead air to produce an effective barrier, while the extra-thick, fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration, adding up to greater energy savings – and lower utility bills.  Sheffield Windows feature a sloped sill helping to prevent air and water infiltration while maintaining a timeless, detailed appearance.  Beveled mainframe on double-hung and sliding windows complement any home's style.  Best yet, Sheffield Windows are covered by Alside’s impressive Lifetime Limited Warranty for complete peace of mind.
