Window Types Explained: Double Hung, Casement, and Tilt & Turn

Which Is Best for Your NYC Home?

Choosing the right window type for your home or building can dramatically improve comfort, airflow, energy efficiency, and overall property value. In a city like New York — where buildings range from pre-war brownstones to modern luxury high-rises — each window style offers unique benefits.

At NYC Glass & Window Repair, we service, replace, and install all major window types. Below is a clear, expert explanation of the three most popular styles.

1. Double-Hung Windows — The Classic NYC Window

Double-hung windows are one of the most common window styles in NYC apartments, condos, and townhouses. They feature two sashes that move up and down within the frame.

✔ How They Work:

  • Upper sash: Moves downward
  • Lower sash: Moves upward
  • Many models also tilt inward for cleaning

✔ Advantages:

  • Ideal for areas facing sidewalks or fire escapes (no outward extension)
  • Easy cleaning with tilt-in sashes
  • Great ventilation with both sashes open
  • Affordable and widely available
  • Works with window AC units

✔ Best For:

Bedrooms, Living rooms, Pre-war buildings, Multi-family properties, Homes requiring window AC installation.

✔ Common Problems We Repair:

Broken balances, Hard-to-open sashes, Drafts, Foggy glass, Misaligned frames, Locking issues.

2. Casement Windows — Maximum Ventilation

Casement windows are hinged on the side and open outward using a crank handle. They are extremely popular in modern construction and energy-efficient remodels.

✔ Advantages:

  • Outstanding ventilation — catches breezes like a sail
  • Top-rated energy efficiency (excellent airtight seal)
  • Great for hard-to-reach locations (over sinks, counters)
  • Modern, clean appearance with unobstructed views

✔ Common Issues We Fix:

Crank mechanism failure, Sash misalignment, Seal failure causing drafts, Broken hinges.

3. Tilt & Turn Windows — Premium European Functionality

Tilt & Turn windows are becoming increasingly popular in NYC’s luxury residential market. This European-style system offers two opening functions in one window, controlled by a single handle.

✔ How They Work:

  • Turn mode: Window swings inward like a door
  • Tilt mode: Top tilts inward for secure ventilation

✔ Advantages:

  • Exceptional ventilation options
  • High security with multi-point locking
  • Excellent energy performance
  • Superior soundproofing when paired with laminated glass

Materials Available for All Window Types

Most window styles come in several frame materials: Vinyl / uPVC, Aluminum, Wood, and Fiberglass. We supply, install, and repair all frame types.

Difference Between Vinyl Windows and uPVC Windows

When searching for new or replacement windows, homeowners often come across two similar-sounding materials: Vinyl windows and uPVC windows. Although many people assume they are the same, there are important differences in durability, strength, energy efficiency, and long-term performance — especially in a demanding climate like New York City.

At NYC Glass & Window Repair, we service and install both materials and help clients choose the best option based on their building type, budget, and long-term goals. This guide breaks down the true differences between vinyl and uPVC so you can make an informed decision.

What Is Vinyl?

Vinyl windows are made from PVC mixed with plasticizers — chemicals added to increase flexibility and reduce brittleness. This makes vinyl windows more flexible, easier to manufacture, and available in more colors. Vinyl has been used for decades in residential window frames across the U.S.

✔ Benefits of Vinyl Windows

  • Affordable and widely available
  • Smooth, attractive appearance
  • Good energy efficiency
  • Low maintenance
  • Many color options

⚠ Drawbacks

  • Plasticizers can break down over time
  • Can warp under extreme heat
  • Becomes brittle in very cold climates
  • Slightly lower structural strength compared to uPVC

What Is uPVC (Rigid Unplasticized PVC)?

uPVC — also known as Rigid PVC or Unplasticized PVC — is a stronger, stiffer formulation of PVC that contains no plasticizers. This makes uPVC more rigid, durable, and resistant to warping. It is the standard material used for high-quality European windows, including many Tilt & Turn systems.

✔ Benefits of uPVC Windows

  • Extremely durable and rigid
  • Better structural strength
  • Excellent insulation and thermal performance
  • Highly resistant to UV fading
  • Does not warp under heat
  • Fire-resistant and self-extinguishing
  • Often lasts 30–50 years

⚠ Drawbacks

  • More expensive than standard vinyl
  • Fewer color options
  • Heavier frame material (requires better hardware)

Vinyl vs uPVC — Side-by-Side Comparison

Feature Vinyl Windows uPVC Windows (Rigid)
Material PVC with plasticizers PVC without plasticizers
Strength Flexible, less rigid Strong, rigid, structurally superior
Longevity 15–25 years 30–50 years
Warp Resistance May soften in heat Highly resistant
Energy Efficiency Good Excellent
Cost More affordable Higher upfront cost
Best For Budget replacements Premium / Tilt & Turn

If you want maximum durability and performance, uPVC is the clear winner.

Why uPVC Is Preferred in European Tilt & Turn Windows

Most European window manufacturers — including Reynaers, Veka, Schüco, Rehau — use uPVC because of its structural rigidity, long-term stability, and ability to support heavy multi-point hardware.

Tilt & Turn windows require stronger frames because they hinge inward and tilt from the top. Vinyl simply cannot support this hardware system as well as uPVC.

Which Material Performs Better in NYC?

NYC’s climate has hot summers, cold winters, high humidity, massive temperature swings, and coastal salt air. This environment is tough on window frames.

✔ Vinyl performs well for: Standard double-hung windows, budget-conscious replacements, low-rise residential buildings.

✔ uPVC performs best for: Luxury apartments, high-rise buildings, homes near water, European Tilt & Turn systems.

Energy Efficiency Comparison

Both vinyl and uPVC provide excellent insulation, but uPVC has a tighter molecular structure, giving it better thermal resistance and stronger air seals. If energy costs are a major concern, uPVC is the superior choice — especially when paired with Low-E or laminated IGU glass.

Which Should You Choose?

Choose Vinyl if you want: A cost-effective replacement, multiple color options, and good energy efficiency at a lower budget.

Choose uPVC (Rigid) if you want: Higher durability, maximum energy efficiency, superior strength, and long-term performance.

Tilt & Turn Windows — Common Problems & Fixes

Tilt & Turn windows are one of the most advanced window systems available today, offering exceptional ventilation, security, and energy efficiency. Popular in Europe for decades and increasingly common in modern NYC apartments and luxury renovations, these windows operate in two ways:

  • Tilt Mode: The top tilts inward for secure ventilation.
  • Turn Mode: The sash opens inward like a door for maximum airflow and easy cleaning.

While Tilt & Turn windows deliver unmatched performance, they rely on a complex multi-point hardware system. At NYC Glass & Window Repair, we specialize in diagnosing, repairing, and adjusting all Tilt & Turn window systems across Manhattan, Brooklyn, Queens, the Bronx, Long Island, and Westchester.

1 Window Is Stuck in Tilt Mode

The most common problem. The window becomes "jammed" in tilt position and won’t respond to the handle.

Causes:
  • Handle moved at the wrong angle
  • Sash shifted out of alignment
  • Multi-point lock malfunction or Gearbox failure
Fix: We safely re-engage the hardware, realign the sash, and reset the multi-point mechanism. If needed, we replace the gearbox.

2 Window Won’t Close Fully

If the window won’t sit flush against the frame or leaves gaps, there is a sealing or alignment issue.

Causes:
  • Sash has dropped over time
  • Hinges loosened or warped
  • Frame settlement in older NYC buildings
Fix: We adjust hinge geometry, tighten mounting points, realign the sash, and calibrate the locking points.

3 Drafts or Air Leaks

Tilt & Turn windows are designed to be airtight. If you feel a draft, something is wrong.

Fix: Replace all gaskets with high-compression European seals, adjust closing pressure, and seal small perimeter gaps.

4 Handle Is Loose or Spins Freely

The handle controls the entire system. If it spins without engaging, the hardware inside has failed.

Causes: Worn gearbox, stripped handle spindle, or internal lock failure.
Fix: We replace the handle, spindle, or gearbox using exact-match European hardware.

5 Sash Is Crooked or Sagging

Over time, the weight of the sash can pull it downward, causing dragging and uneven opening.

Fix: We perform a full sash adjustment — raising, leveling, and tightening hinge points for perfect alignment.

6 Window Falls Open Unexpectedly

This is a safety hazard and usually indicates a tilt mechanism failure.

Fix: We replace the faulty tilt arm or pivot shoe and ensure the safety catch engages properly.

7 Foggy or Moisture-Filled Glass

Moisture between panes means the seal has failed.

Fix: We replace the IGU (glass unit) only, not the entire window frame — saving you money.

8 Noisy Operation & Water Leaks

Grinding sounds or water leaks around the frame usually point to maintenance needs.

Fix: We lubricate tracks, replace dry hinges, reseal gaskets, and clear drainage paths.

How to Prevent Problems

Tilt & Turn windows last 20–40 years when properly maintained.

  • Lubricate hardware annually
  • Clean hinges & locking points
  • Avoid forcing the handle
  • Replace worn gaskets quickly

Double-Hung Windows — Common Problems & Fixes

Double-hung windows are one of the most popular window types in New York City. They’re space-saving, easy to clean, compatible with window AC units, and commonly found in pre-war buildings, condos, and multi-family homes.

But like all mechanical systems, double-hung windows rely on balances, sash cords, locks, and tracks — and over time, these components wear out. At NYC Glass & Window Repair, we service thousands of double-hung windows across Manhattan, Brooklyn, Queens, the Bronx, Long Island, and Westchester.

1 Window Won’t Stay Open

The #1 problem. Balances (springs/counterweights) inside the frame fail, causing the sash to slam shut or become heavy.

Causes:
  • Worn-out springs or broken cords
  • Damaged pivot shoes
  • Improper tension or age
Fix: We replace window balances with new, calibrated units matched to your sash weight.

2 Hard to Open or Close

If you need to force the window or it sticks halfway.

Causes:
  • Dirty or damaged tracks (paint/dust)
  • Broken balance on one side
  • Warped frame or sash swelling
Fix: Clean and lubricate tracks, replace broken balances, and adjust frame components for smooth operation.

3 Sash Tilts or Feels Loose

Occurs in modern tilt-in windows when hardware fails.

Causes: Broken pivot bars, damaged pivot shoes, or worn-out tilt latches.
Fix: We replace faulty parts with exact-match components and re-align the sash.

4 Drafts or Air Leaks

Cold air leaking in increases energy bills and discomfort.

Causes: Worn weatherstripping, loose sashes, gaps around frame, or bowed frames.
Fix: Install new weatherstripping, tighten sash alignment, and seal perimeter gaps.

5 Foggy Glass (Moisture Between Panes)

Fog, haze, or water droplets between the glass means the seal has failed.

Fix: Foggy windows cannot be "cleaned." We replace only the insulated glass unit (IGU), not the entire frame, saving you money.

6 Broken or Loose Locks

Reduces security and energy efficiency.

Fix: We repair or replace the lock and ensure both sashes meet properly for an air-tight seal.

7 Tilt Latches Not Working

Latches allow the sash to tilt in for cleaning. If broken, the sash may fall inward unexpectedly.

Fix: We install new tilt latches and reset the sash securely into the jamb liners.

8-9 Rattling & Locking Issues

Windows that rattle or won't lock properly usually have alignment or balance issues.

Fix: We tighten components, replace seals, realign sashes, and adjust the balancing system.

How to Prevent Problems

Routine maintenance dramatically extends window life:

  • Clean tracks twice a year
  • Check weatherstripping annually
  • Keep tilt latches in good condition
  • Avoid forced operation

Casement Windows — Common Problems & Fixes

Casement windows are one of the most efficient window styles available today. They open outward like a door using a crank mechanism, allowing excellent ventilation and creating an airtight seal when closed. Because of their performance and ease of operation, casement windows are widely used in modern NYC apartments, condos, brownstone renovations, and commercial spaces.

But despite their advantages, casement windows contain multiple moving parts — cranks, hinges, locks, and seal systems. At NYC Glass & Window Repair, we repair thousands of casement windows every year across Manhattan, Brooklyn, Queens, the Bronx, Long Island, and Westchester.

1 Window Won’t Open or Gets Stuck

If the handle turns but the window barely moves, the issue is usually mechanical.

Common Causes:
  • Worn-out or stripped operator (crank)
  • Rusted or bent arm linkage
  • Sash binding or warped
Fix: We diagnose the operator system and replace the crank, gears, arm, or track components.

2 Broken or Loose Crank Handle

A stiff or broken crank handle is one of the most common complaints.

Why It Happens:
  • Oversized or heavy sash
  • Lack of lubrication / Gear wear
  • Bent operator arm
Fix: Replace the operator, install a stronger crank system, and lubricate hinges.

3 Window Won’t Close or Seal Properly

If your window closes unevenly or won’t “sit” fully in the frame.

Causes: Bent/broken hinges, sagging sash, frame movement, or loose screws.
Fix: We re-seat the sash, tighten hardware, adjust hinge geometry, and restore a tight seal.

4 Drafts or Air Leaks

If you feel cold air coming in, something is wrong with the sealing system.

Causes: Worn weatherstripping, warped sash, or misaligned lock mechanism.
Fix: Install new weatherstripping, adjust sash alignment, and seal perimeter gaps.

5 Foggy or Moisture-Filled Glass

Condensation between panes means the insulated glass unit (IGU) seal has failed.

Symptoms: Fog, haze, water droplets, or calcium deposits inside glass.
Fix: We replace the entire insulated glass unit (IGU) only, not the whole frame.

6 Window Won’t Latch or Lock

If the lock doesn’t engage, your window is not secure or weather-tight.

Fix: We realign the sash, adjust the lock system, or replace worn cam locks.

7 Broken or Rusted Hinges

If hinges fail, the window may open unevenly, drop on one side, or become dangerous.

Fix: We replace hinges with exact-fit parts and correct sash alignment.

8 Opens Too Far (Wind Damage)

Casement windows act like sails. Strong NYC wind can stress hardware.

Fix: Install limiters to control opening distance and upgrade hardware.

9 Water Leaks

Leaks usually occur around gaskets, frame edges, or clogged weep holes.

Fix: We reseal the perimeter, replace gaskets, and address frame drainage.

How to Prevent Casement Problems

Routine maintenance keeps windows operating smoothly:

  • Lubricate crank mechanisms twice a year
  • Clean dirt from tracks
  • Avoid forcing window in strong wind
  • Inspect weatherstripping annually
