Secondary Glazing Online: made-to-measure secondary glazing manufactured in Canvey Island

Secondary Glazing Online is a British manufacturer specialising in made-to-measure secondary glazing that sells its production directly, without intermediaries, at prices the company itself presents as trade prices. The company operates from its factory in Canvey Island, Essex, and serves orders throughout the United Kingdom with delivery within ten working days.

Its business model is based on direct-from-factory sales and an online configurator that provides an instant quote by entering measurements, window style and desired finishes. The company offers technical support in the United Kingdom and a ten-year guarantee on its products.

Available secondary glazing systems

The catalogue is organised into six systems designed for different opening, access and appearance needs:

• Fixed: ultra-slim and simple to install, suitable for openings where access to the existing window is not required. The company presents it as the option with the best thermal performance and maximum noise reduction.
• Horizontal Slider: designed for wide multi-pane windows with vertical bars, such as casement windows. Panels slide to allow ventilation and can be removed for cleaning.
• Vertical Slider: suitable for windows with horizontal bars, such as sash windows. It can include balances and a tilt-back system for easy cleaning.
• Hinged: recommended for bay windows and applications requiring emergency escape, as it provides a wide opening for ventilation and full access.
• Lift Out: for tight spaces or hard-to-reach areas, with a minimal frame and a clean look. The company highlights it as a cost-effective solution for occasional access.
• Horizontal Slider with vertical bars: a specific variant for windows with vertical bars that combines sliding with the aesthetics of the original window.

Configuration: finishes, glass and options

The online configurator allows you to choose the window style, panel layout, frame finish and glass type. Available frame finishes include white (the most popular), brown, light grey, dark grey, black and custom RAL colours, with a choice of gloss, semi-gloss or matt finish.

As for glass, single and double glazing options are offered. Single glazing options include 4 mm toughened (the most popular), 6 mm toughened, 6.8 mm acoustic laminated for noise reduction, 6.8 mm laminated for security, and obscure glass for privacy, with a wide variety of decorative patterns. Double glazed units include combinations such as 4 mm toughened with a 12 mm spacer and 4 mm toughened, a Low-E version, and options with laminated or acoustic glass.

Measuring, installation and lead times

The company distinguishes between recess measurements and exact measurements. If the customer provides recess measurements, the factory automatically deducts 6 mm from the width and height; if exact measurements are chosen, it manufactures to the specified size. Installation is presented as a simple DIY project, with measuring guides and technical support available.

The standard lead time is ten working days for all zones, with free delivery in zone 1. Special units may take up to fifteen days. The company sells its products throughout the United Kingdom.
