Church Windows

Church WindowsJ. Sussman, Inc. church window frames are specially designed to receive both stained glass and protective glass in the same frame. Besides protection from vandalism and natural causes these church window systems provide enhanced insulation from the sound, heat and cold, and can substantially lower fuel costs and conserve energy.Church windows historically refer to windows made to receive both stained glass and protection glass in the same frame. This has been J. Sussman’s specialty since the company started in 1906. We have systems for insulated protection glass and monolithic protection glass.

In Sussman church window frames the separation of stained glass and protective glass is achieved by a channel that is an integral part of the extrusion. (Not an add on piece.) This channel acts as a condensation gutter and helps prevent air and water infiltration.

J. Sussman, Inc. church windows can easily be vented to reduce condensation and heat build up between the stained glass and protective glass.

J. Sussman Inc. church windows are available in a heavy triple glazed system 6400 Series (stained glass and insulated glass) or a double glazed system 300 Series (stained glass and monolithic protective glass), with and without thermal breaks respectively. These church window systems can be configured with combinations of fixed, projected and casements and our 300 Series is even available with the historical church standard, the Horizontally Center Pivoted ventilator.

Standard anodized finished are clear and dark bronze. Standard painted finishes are white and bronze baked polyester meeting AAMA 2603. Custom anodized colors and high performance paint colors meeting AAMA 2604 or 2605 are also available. See Paint Comparison Chart.

6400 Series Stained Glass Church Window Frame for Stained Glass and Insulated Protection Glass
Hurricane/Impact Code Approved FL# 14163

6400 SeriesThe 6400 Series is a heavy triple glazed Church Window incorporated into a 3 1/2” thermally broken frame. This Church Windows is made for insulated protection glass and Stained Glass. It is Hurricane/Impact approved and is available with hurricane glazing. The thermal break is achieved with the use of Thermal Strip technology. Two different aluminum extrusions can be finished independent of each other and then joined with polyamide nylon strips. The result is a stronger thermally improved window with the possibility of different finishes interior and exterior. This combination, along with triple contact weather-stripping in the ventilator, provides maximum condensation resistance and superior insulation making it the ideal choice for church windows when heating, condensation, noise and protection of stained glass are factors.

6400 Details

Features:

  • Main frame and sash members are a full 3 1/2″ deep. Ventilators, frame, muntins and meeting rails are double tubular and will meet or exceed AAMA P-HC70 F-AW80 monumental performance specifications. Hurricane/Impact Design Pressure-DP65
  • Triple glazed thermal barrier design that can accommodate 1″ protective insulated glass with another 5/8″ airspace between the art glass insulates the cold outside temperatures from the warmer inside temperature and helps prevent condensation and noise infiltration.
  • Venting is available to help eliminate condensation between the stained glass and the insulated protective glass. Vent holes are screened and hooded to prevent insect, dust and water infiltration.
  • The thermal strip is a specially formulated and constructed extrusion of glass fiber reinforced 6/6 polyamide nylon. Besides being thermally efficient, these high strength strips have the same coefficient of expansion as aluminum so that the structural integrity of the window is intact.
  • The separation of art and protective glass is achieved by a channel that is an integral part of the extrusion. (Not an add on piece.) This channel acts as a condensation gutter and helps prevent air and water infiltration.
    – Ventilators have 3 rows of continuous weather-stripping.
  • Windows can also accommodate interior faceted glass and an exterior protective glass.
  • Special Feature: Large sections of insulated glass can be installed on the exterior and for the art glass special narrow siteline muntins can be placed in the interior of the frame in virtually any shape or size to suit the design and help keep costs down. (These interior muntins can also be installed at a later date to fit the design.)

Weeping the exterior insulated glass to prevent glass failure

The greatest cause of insulated glass failure is the seal around the glass breaking down. That is usually caused by water coming in direct contact with the seal. Water is the enemy of the seal and the seal will deteriorate without proper weepage. Insulated glass manufacturers will not warranty their glass if water is not weeped away from the glass. The 6400 Series church window features an isolated water pocket away from the glass to prevent the insulated glass from sitting in water. The system allows positive weepage away from the glass to the exterior.

Weeping & VentingVenting to reduce condensation and heat buildup
Condensation and heat buildup between the protective glass and the stained glass can deteriorate the stained glass. There are many ways to combat condensation and heat buildup in a church window. The 6400 Series church window with insulated glass and its thermal break frame will be adequate in most cases. Due to variables such as location, altitude, climate, humidity and orientation to the sun some conditions will require additional measures. For more extreme conditions J. Sussman recommends the following options:

  • We recommend using SUS-FILLER tape to glaze the interior stained glass. SUS-FILLER is a single sided self adhesive open cell foam tape. It is used instead of caulking or glazing tape and allows the air space between the glasses to breathe yet will filter out dust, dirt and insects. The glass is dry set which makes for a simple, fast, clean and economical installation.
  • Using high performance glass such as glass with a low-emittance (low-E) coating (on the #2 surface) is an excellent way to reduce heat buildup between the glasses and condensation. Low-E glass coatings reduce solar heat gain while retaining high visible transmittance. Air conditioning and heating costs will be further reduced by using high performance protective glass.
  • Venting within the window can be achieved by strategically placing special ventilation slots in the frame and glazing beads. Slots at the top and bottom allow air to circulate by natural convection. This cools off the airspace and helps eliminate condensation. The tubular profiles in the 6400 church window prevent dirt and dust around the perimeter from infiltrating the air space.

300 Series For Stained Glass and Single Pane Protection Glass

The 300 series is the original aluminum double glazed church window that has been the “standard’ of the industry for over 60 years. It is specially designed to receive stained glass on the interior and protective glass on the exterior. This “Double Glazing” protects the stained glass from vandalism while also insulating from the heat and cold and reduces outside noise infiltration. The insurance and fuel costs can be substantially lower as a result of the “Double Glazing”. Venting is available to help eliminate condensation between the stained glass and the protective glass. Vent holes are screened and hooded to prevent insect, dust and water infiltration.

300 Series

Features:

  • All frame and sash members are a full 2 1/2” deep and will meet or exceed AAMA P-C70 and F-HC70 monumental performance specifications.
  • The channel that separates the glass is an integral part of the extrusion that also acts as a condensation gutter, and helps prevent theft, and air and water leakage.
  • Either glass can be installed or replaced without disturbing the other. The exterior glass can be installed at time of erection to close up the building and the stained glass installed at a later date of the churches own convenience or when the necessary funds are available. (Art glass can be an excellent fundraiser.)
  • Ventilators are available as project-in, project-out and the standard horizontally center pivoted. (Center pivoted vents are recommended because the weight of the sash is evenly balanced for ease of operation and chain operation is a safe alternative to window poles.)
  • All double glazed ventilators are of overlap design to minimize sightlines.
  • The 300 series is interchangeable with and lines up with the 400, 500 and 600 series.
