Select Replacement Inserts by Frame Material and Glass Configuration
Basement window inserts are drop-in replacements that resolve failed seals, condensation, and operational issues without full frame replacement. Field-proven C-series aluminum and C-series vinyl designs accommodate standard well dimensions. Proper sizing and material selection ensure code compliance for egress openings and thermal requirements in below-grade applications.
Aluminum and Vinyl Inserts for Existing Well Frames
Replacement inserts fit established basement openings without frame removal. Measure existing well width, height, and depth to match C-300 single-pane aluminum, C-310 dual-pane aluminum, or C-400 dual-pane vinyl specifications. Identify frame type and glass configuration from unit markings to confirm correct SKU before ordering.
Dual-Pane and Single-Pane Specifications by Installation Type
Dual-pane inserts (C-310, C-400 series) reduce condensation and improve R-value; single-pane (C-300) serves applications where thermal upgrade is secondary. Variant suffixes (K, M, A) indicate frame finish and glazing options. Cross-reference existing unit specs with product datasheets to avoid sizing mismatches on depth or reveal dimensions.
Custom Sliders and High-Volume Trade Support
C-580 custom basement sliders handle non-standard openings for renovation and new construction. Trade contractors managing multi-unit projects access consolidated SKU data, compatibility matrices, and bulk ordering through dedicated account support. Technical specifications and field notes available for each variant to expedite installation coordination.
