Duplex AKA 'Multi Spacer' and 'Back to Back'

Adding Duplex to the internal construction of a sealed window unit is to segment the unit into individual units for external (Astragal) bars to be applied when fitting. We offer up to 5 spacers both horizontal and vertical. Total width of the Duplex Bar is either 18mm or 25mm. The coordinate 'X' marks the centre of the location of a vertical bar/duplex and 'Y' marks the centre of the location of a horizontal bar/duplex. Our system calculates the position of the bars/duplex based on the overall width or height of the window and divides and then places the specified amount of bars at equal intervals. Try it and see! You can also type in the exact coordinates should you choose to have the bars in different locations such as borders. Please note the colours of the Duplex Bars will match that of the unit's Spacer Bar you have chosen.

Glazed Stepped Unit Options

We can supply Glass Sealed Units with steps to suit your requirements. 'Stepped Units' are when one pane of the double glazed unit is larger than the other. This creates a step that can be for several purposes. The common use for stepped units are conservatory roof units and skylight units. On Conservatory roofs this is used as a drip for water to flow into guttering and keeping moisture clear of the double glazed seal. Another reason for a step is pictured below where it is used for skylights and allows the upper pane to be placed onto the upstands and again allowing water to drip clear of the seal and used to cover/waterproof the upstands. The website calculates your unit price based on the number of edges that requires a step. Once you have placed the order our customer service team will contact you to discuss your step requirements.

Frequently Asked Questions - Double Glazed Units

Softcoat is a clear Low Emissivity Glass with a coating on the inside of the inner pane that reflects heat back into the building, giving thermal insulation performance. Read more about Softcoat Glass at Glass Delivered.

Aluminium spacer bars are commonly used in double-glazed windows to separate the panes of glass, providing structural integrity and thermal insulation. However, they are highly conductive, which can lead to heat loss and condensation issues around the window edges. Warm edge spacer bars, on the other hand, are made from materials with lower thermal conductivity, such as composite materials or stainless steel. These bars help reduce heat transfer, improving the window’s overall energy efficiency and reducing the risk of condensation. As a result, warm edge spacer bars are generally considered a better option for enhancing insulation and comfort.

Standard glass thickness is 4mm; however, the choice of glass depends on your specific needs, such as energy efficiency, sound insulation, privacy, or aesthetics. At Glass Delivered, we supply a wide range of custom glass specifications to suit every project.

Yes, Glass Delivered supplies high performance solar control glass. Please feel free to refer to our data sheets to find the details of the SKN176 – Cool Lite. This option can be located on the OUTER glass section on our website.

Yes, Glass Delivered can supply custom double glazed units with precision circular holes to meet your specific pet flap or extractor vent requirements.

The spacer bar size depends on the thickness of the glass and the overall thickness of the double glazed unit. A standard double glazed unit typically uses 4 mm glass in each pane, so the spacer bar can be worked out from the overall unit thickness. For example, a 4 mm / 16 mm spacer / 4 mm unit has an overall thickness of approximately 24 mm. If the glass is a different thickness, the spacer size will need to be calculated accordingly. If you are unsure of the specification, Glass Delivered can help you identify the correct spacer bar size before ordering.
