The Contura i2 fireplace insert is a compact 5 kW cassette fire designed for customers who want more freedom over how a fireplace looks and performs. It works equally well for building a completely new fireplace feature or upgrading an older open fire, giving you a practical inset format with modern wood burning efficiency.
A key strength of this model is its versatility. The compact size makes it easier to position in a wide range of fireplace openings, while the choice of a 3-sided or 4-sided frame gives more control over the final finish. That makes it well suited to both bespoke fireplace projects and renovation work where the insert needs to sit neatly within an existing structure. The product data also highlights an important practical benefit over an open fire: instead of allowing heat to escape up the chimney, a cassette insert helps deliver a more pleasant heat into the room through the glass. With 82% efficiency, 5 kW output and a maximum heating area of 120 m², the i2 is designed to improve both heating performance and the everyday usability of the fireplace.
This model is also positioned as a more modern combustion solution. The product data refers to cleaner, more modern combustion technology, making it a stronger option than a traditional open fire where efficiency is low and usable room heat is often limited. For customers looking to retain the feel of a real fireplace while upgrading how it performs, that is a meaningful advantage.

Expert Insight
Cassette inserts like this are often one of the most effective ways to improve an underperforming open fireplace. Open fires can lose a significant amount of heat up the chimney, whereas a well-designed inset cassette gives the room a much more usable heat output. That makes models like the i2 particularly attractive for renovation projects where the aim is not just to change the look of the fireplace, but to make it work better as a heating appliance.
The choice between 3-sided and 4-sided trim is also an important practical detail. It affects how the insert finishes against the opening and gives more flexibility depending on whether the surrounding edge is being hidden, framed or left visible.
Suitability
The Contura i2 is well suited to fireplace refurbishments, compact built-in fireplace projects and homes where an existing open fire needs upgrading to something more efficient. It is a strong choice for customers who want a practical inset wood burning fire with design flexibility, modern performance and a more useful heat output than a traditional open fireplace.
