Manko’s 725 series hung window system was designed as a true single window with the intention of meeting the replication of historical windows. This series is ideal for buildings seeking a replacement window or for new projects seeking a historical look. The 725’s design includes pour and debridged thermally broken main frame and operable sash to provide improved thermal efficiency. Main frame and operable sash construction is mortise and tenon joinery with dual integral screw races. Structural glazing allows for a weather tight glazing seal. For added durability and extended operating life, the operable sash smoothly slides with either block and tackle or ultra-lift balances. If your project is seeking a quality single hung window with a historical profile, Manko’s 725 series can be the perfect fit. 725 Historical — Single Hung ▪ Fixed Features: 3 1/4” overall frame depth 3/4” insulated glass Dual finseal weathering on operating sashes Preglazed at factory for added quality control Extruded screen frames with aluminum screen wire Exterior applied & between glass muntins available Panning systems & interior snap trims available Custom configurations with standard details available Full range of anodized & AAMA 2605 painted finishes Performance Results: AAMA — CW40 Air Infiltration — 0.3 CFM* Water Resistance — 10 PSF* *Minimum gateway performance values listed, product meets or exceeds values
