There's only one window that meets Apex Energy Solutions' high standards for quality and energy efficiency: Alside's Flagship product, the Signature
8000 Series.

Why? It's all in the details:

Convenience

Tilt-in sashes for cleaning ease.

Variety

Colors, styles and designs to meet every need.

High Efficiency

Triple-paned insulated glass to provide high efficiency and visibility (outperforming most mid-priced low-E glass systems by more than
125 percent).

The heart of the Signature 8000 Series platform is uPVC Resin which utilizes a “European water cooled” extrusion process for added strength. This advanced uPVC is rugged, durable and virtually maintenance free.

Solid and tough uPVC frames and sashes that never chip, peel, crack or warp.

Fiberglass reinforced sashes for superior rigidity and non-conductive thermal properties.

Pinch-point fusion welding, which virtually forges the entire window into a single, solid unit that won't lose its shape, bend, flex, weaken or warp.

Trinity Windjammer Interlock System that seals against wind and water infiltration and delivers increased security.

High-density poly-tech foam-filled frames to reduce conduction and capture energy savings.

But we're not the only ones who believe the Signature 8000 is top-notch. Independent testing agencies routinely rate them high in every category. Some recent results include:

• Signature 8000 Series Windows easily passed rigorous air-infiltration-resistance testing procedures of the American Society for Testing and Materials (ASTM).
• Signature 8000 Series Windows withstood the equivalent of eight inches of rain an hour blown onto the window at 60 mph.
• Signature 8000 Series Windows maintained structural strength and integrity in tests simulating winds of more than 155 mph.
• Signature 8000 Windows have been inspected and tested by Underwriters Laboratories, which certified them as UL classified to ASTM E84.
