Incarnation Window Systems

Discover a range of secondary glazing solutions that not only perform well but are each custom made in-house, tailored to your exact requirements and fit seamlessly onto existing frames. When fitted correctly secondary glazing is a near-invisible addition that still manages to bring performance benefits akin to double/triple glazing. While secondary glazing is traditional used in classic homes intent on retaining authenticity, our units are suitable can be tailored to suit both residential and commercial applications.

Since our establishment in 2012, the team here at Incarnation Windows have made it our mission to provide installers nationwide with the slimmest secondary glazing solutions possible. Specifically intended to provide listed buildings and those of a classical nature with improved insulation, noise reduction, and efficiency levels that are environmentally sound, secondary glazing is a small touch that has a big impact. We engineer every secondary glazing unit using lightweight aluminium, which can then be fitted inside an existing window frame across a wide range of styles suited to match the layout of the original.

Incarnation Windows exclusively focus on the manufacture and supply of high quality secondary glazed units to installers nationwide. However, we recognise the high demand for such a specialist product, often being contacted by homeowners across the UK fortunate to live in conservation areas and listed properties. In this instance we'd be more than happy to put you in touch with a respected double glazier featured in our network, one that knows secondary glazing almost as much as us. Every Incarnation Windows-approved installer should be considered an extension of ourselves, coming fully vetted and certified by us directly to fit our secondary glazed products to the highest standard.

Our secondary glazed vertical sliders are designed from the ground up to fit over traditional sliding sash or modern 'mock sash' windows. As one of the most popular window styles found in listed buildings, they use tensioned balances to support the sashes, letting them slide up and down easily. When happy, counterbalanced hardware allows the sash to be left in any desired position. We also produce a deluxe vertical sliding option with sashes that tilt in addition to sliding for maximum cleaning ability and flexibility.

Deluxe vertical sliders successfully offer the same benefits as our standard option, albeit with one significant bonus. With 45-degree angle tilt-in facility, they are the most sophisticated type of secondary glazing available, letting the sash allow for safe cleaning and ventilation while retaining a high bar for security alongside authentic sightlines. In addition to this, sashes can be fully removed. The Classic Collection represents Incarnation's standard range of secondary glazing solutions, well-suited to installers seeking an ideal solution to insulate Listed buildings and rural properties.
