Adding Georgian Bars to the internal construction of a sealed glazed unit is a simple way to replicate classic old Georgian style windows. We offer up to 5 bars both horizontal and vertical. The Bars are available in white and wood effect and come in both 18mm and 25mm widths. 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 type in the exact coordiantes should you choose to have the bars in different locations such as borders. Other colour and options are available please call to discuss your requirments on 01234 339800.

We supply leaded Triple Glazed units for new builds or to replacement damaged or failed units. We can customize each individual unit so the patterns follow through on the surrounding windows/units. In some cases you will be contacted for more information to ensure we accurately reproduce what is required. Please see our many formats within the Lead pulldown options. The lead we use come in both 6mm and 9mm widths and are available in either antique or bright finish.

We can supply Glass Sealed Units with steps to suit your requirements. 'Stepped Units' are when one pane of the triple 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 triple 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.

Shaped Units inc. Raked Tops, Arches and other shapes are available as an extra for your sealed unit/s. For a single straight cut (Raked/Triange units) simply select 'Single Cut Shape'. For circles, arches, templates and any other shapes select the 'Multi-Cut Shape' option. The website calculates your unit price based on the option you have chosen. Once you have placed the order our customer service team will contact you to discuss your shaped requirements. You can either supply us a drawing or send us actual templates to match.

Used to create the airspace between the two panes of glass and hold the molecular sieve (desiccant), spacer tube also helps to maintain a unit's structural integrity. It is available in a range of widths and heights (Sightlines). Small perforated lines run down the centre of spacer bar around its inner surface. Breather holes allow the passage of gas into the spacer bar where desiccant is held. Several types of spacer bar are available including: Aluminium in Silver, Gold or Brown (Bronze), and warm edge in either Black, White or Grey. Warm edge bar offers a more thermally efficient solution.

Please use upload your shaped glass file here. We do still however, require you to complete the 'Width' and 'Height' dimensions in the 'Order Area', this needs to allow for the shape to be cut from the glass so please ensure the dimensions allow for the shpaed glass to be cut from. We have to charge for the off cuts off that overall sheet of glass. Shaped glass is charged at an additional 50% fee.
