Window Installation Course

Lesson 1 • Anatomy of a Window Unit

Identifies every component of a window assembly from frame to glazing. Understanding parts enables accurate measurement, ordering, and installation planning.

Lesson 2 • Industry Standards and Codes

Introduces performance standards, energy codes, and safety regulations governing window installation. Compliance knowledge prevents costly rework and liability.

Lesson 3 • Window Types and Their Applications

Covers single-hung, double-hung, casement, awning, sliding, and fixed windows. Establishes vocabulary and selection criteria used throughout the course.

Lesson 1 • Personal Protective Equipment

Establishes PPE requirements for cutting, lifting, and working at height. Proper protection reduces injury risk and meets worksite safety regulations.

Lesson 2 • Hand and Power Tools for Installation

Identifies and demonstrates proper use of measuring, cutting, and fastening tools. Correct tool selection directly affects installation speed and accuracy.

Lesson 3 • Material Handling and Storage

Teaches proper receiving, inspection, and storage of window units and materials. Preventing damage on-site protects project timelines and profit margins.

Lesson 4 • Worksite Safety and Hazard Control

Addresses fall prevention, glass handling, lead paint, and silica dust hazards. Hazard identification and control are mandatory before any installation begins.

Lesson 1 • Measuring Rough Openings Accurately

Teaches width, height, and diagonal measurement techniques for rough openings. Precise measurements determine correct unit size and shimming requirements.

Lesson 2 • Assessing Existing Wall Conditions

Evaluates framing, sheathing, moisture damage, and insulation before installation. Condition assessment determines prep work scope and prevents hidden failures.

Lesson 3 • Ordering and Specifying Window Units

Translates field measurements into accurate window specifications for ordering. Correct specifications prevent returns, delays, and installation compromises.

Lesson 1 • Sheathing and Air Barrier Integration

Explains how to integrate window openings with wall sheathing and air barrier systems. Continuity of the air barrier prevents infiltration and moisture problems.

Lesson 2 • Opening Inspection and Approval

Establishes a pre-installation checklist to confirm the opening is ready for the window unit. Inspection prevents installation over defects that cause future failures.

Lesson 3 • Removing Existing Windows

Details safe removal of old window units without damaging surrounding framing or finishes. Controlled demolition protects the structure and speeds new installation.

Lesson 4 • Framing the Rough Opening

Covers king studs, jack studs, headers, sills, and cripple studs for new openings. Correct framing transfers loads safely and provides a stable mounting surface.

Lesson 1 • Setting and Leveling the Window Unit

Covers lifting, positioning, shimming, and leveling the window unit in the rough opening. A correctly set unit operates smoothly and seals effectively for its service life.

Lesson 2 • Final Checks and Quality Verification

Verifies operation, weathertightness, and appearance before closing the wall. Systematic final checks catch defects while corrections are still straightforward.

Lesson 3 • Insulating and Air-Sealing the Gap

Fills the gap between window frame and rough framing with low-expansion foam or insulation. Proper air sealing eliminates drafts and improves thermal performance.

Lesson 4 • Nailing Fin Attachment

Teaches correct fastener type, spacing, and sequence for nailing fin windows. Proper attachment resists wind loads and maintains the unit's square during cladding.

Lesson 1 • Insert vs. Full-Frame Replacement

Compares insert replacement into existing frames with full-frame removal and reinstallation. Method selection depends on frame condition, budget, and performance goals.

Lesson 2 • Weatherproofing Replacement Installations

Applies exterior caulking, trim, and flashing details specific to replacement scenarios. Replacement weatherproofing must compensate for limited access to the wall assembly.

Lesson 3 • Interior Trim and Finish Work

Restores interior casing, stools, aprons, and drywall after window installation. Quality finish work defines the visible result and client satisfaction.

Lesson 4 • Insert Replacement Procedure

Guides removal of old sashes and installation of a new insert unit into the existing frame. Correct shimming and sealing restore performance without full demolition.

Lesson 1 • Commercial Curtain Wall Window Units

Introduces stick-built and unitized curtain wall systems used in commercial construction. Students understand structural attachment, thermal breaks, and glazing replacement.

Lesson 2 • Bay and Bow Window Installation

Addresses structural support, roof framing, and flashing for projecting window assemblies. Bay and bow windows require coordination of carpentry, roofing, and glazing trades.

Lesson 3 • Skylight and Roof Window Installation

Covers curb-mounted and deck-mounted skylight installation with integrated flashing kits. Roof penetrations demand precise flashing to prevent the most costly leak scenarios.

Lesson 4 • Impact-Resistant Window Installation

Installs windows rated for high-wind and impact zones using reinforced anchoring systems. Correct installation is legally required in hurricane and high-wind regions.

Lesson 1 • Quality Control Inspection Process

Establishes a systematic inspection protocol covering structural, weathertight, and operational criteria. Formal QC reduces callbacks and supports warranty compliance.

Lesson 2 • Diagnosing Common Installation Failures

Identifies root causes of air leaks, water infiltration, fogging, and operational problems. Accurate diagnosis prevents repeat repairs and protects installer reputation.

Lesson 3 • Project Documentation and Closeout

Compiles installation records, warranties, and as-built notes into a complete project file. Thorough documentation protects the installer and supports future service work.

Lesson 4 • Corrective Repair Techniques

Covers re-sealing, re-shimming, hardware adjustment, and glass unit replacement procedures. Efficient repairs restore performance while minimizing disruption to finishes.
