Pella® Impervia® windows and patio
doors are made from Duracast®, Pella's
patented, five-layer fiberglass material.
Pella's AAMA 624 compliant, powder
coat finish resists fading and scratching.
Duracast has many characteristics
that make it the strongest material for
windows and patio doors:
• Engineered for lasting durability.
• 1.8x the tensile strength of conventional fiberglass.
• 2x the tensile strength of aluminum.
• 100x more impact resistant than a leading wood/plastic composite.

Pella’s proprietary fiberglass material has displayed superior strength over wood, vinyl, aluminum, wood/plastic composites, and other fiberglass materials used by leading national brands in tensile and 3-point bend tests performed in accordance with ASTM D638 and D790 testing standards.
Tensile testing performance based on testing 7 samples of each material using ASTMD638 test methodology.
Tensile testing performance based on testing 7 samples of each material using ASTMD638 test methodology.
Impact testing performance based on testing 10 samples of each material using ASTMD256, Method C.

Combination Assemblies
A combination is an assembly formed by two or more separate windows or doors whose frames are mulled together by a combination or reinforcing mullion. A composite is an assembly of windows inside a single, continuous frame.
Pella Impervia products are available in an endless variety of configurations. Refer to the Product Application section of this book, www.Pella.com/professionals or your local Pella sales representative for information on performance and availability.
*Actual mullion span and combination size availability depends on design pressure requirements. Consider combination size, weight and jobsite handling during design.
