Pella’s Impervia fiberglass composite windows and patio doors offer the thermal efficiency of wood, are priced competitively with vinyl, and come in an array of styles, sizes, and options to fit design specifications. Plus there are a variety of new installation options available for use with Pella Impervia products in new construction and renovation projects.
In addition to the traditional methods of installing fiberglass windows and doors with continuous perimeter nailing fins, masonry clips or jamb screws, the new installation systems include:
• Receptor and Subsill for multi-story buildings requiring installation from the interior or when a more robust installation method is needed
• Standard Subframes for replacing wood windows from the building interior
• T-Subframes for replacing metal windows from the building interior
• Reinforcing mullions, expansion mullions, and subsills for single-story storefront style applications
