7/8" Ogee Integral Light Technology
For Pros
Grille Profiles
Integral Light Technology® (ILT) Grilles - Combine the historical look of true divided lights with today's energy efficiency, structural integrity and water-resistant performance. Grilles are adhered to the outside of the glass – wood on the interior and aluminum on the exterior. Between-the-glass nonglare spacers, which are aligned with the interior and exterior grilles, replicate the appearance of true divided lights. Grilles have been approved by the National Park Service on a project-by-project basis for use on historic projects involving federal tax credits.
Grilles-between-the-glass - Permanent aluminum grilles are factory-installed inside the airspace of insulating glass to provide the look of divided lights while making glass cleaning easy. Exterior finish matches aluminum-cladding color.
Removable interior grilles - Roomside wood interior grilles are securely attached to the interior, but can be removed for glass cleaning. Available prefinished to match the interior wood finish and exterior cladding, and in two standard and custom widths.
