The Neverdark C2-TST is a see-through Thermobox for the Chalet-II — open on both faces, so the three-dimensional wood-fire flame is visible from two sides simultaneously. The most striking of the Chalet-II configurations, and the natural choice for a wall shared between two rooms.
Fully insulated to Neverdark's specification — installs directly into combustible surrounds including timber framing and MDF, and can be positioned directly beneath a television without any heat clearance concerns. Available in standard installation (with a front frame covering the wall finish) and hidden installation (fully flush, no frame).
Available from 800 mm to 1,500 mm. Made to order, 6–8 weeks. Contact us to discuss your project.
The C2-TST is the see-through Thermobox for the Chalet-II — open on both faces, with the Chalet-II's three-dimensional wood-fire flame visible from two sides simultaneously. The most striking configuration in the Chalet-II range, and the natural choice where the fire is meant to be looked through as much as looked at.
The See-Through Volumetric Flame
In the C2-TST, both faces of the enclosure are fully open — the Chalet-II's volumetric flame, with its ceramic logs, lava stones and multi-point fire, is visible from either side with nothing between the viewer and the flame. It is a configuration designed for maximum visual impact: the depth and movement of the three-dimensional effect is visible from both directions, and the installation becomes something you look through as much as look at, rather than simply a wall feature. Note that neither long nor short glass borders are available on the C2-TST due to the fully open two-sided configuration.
Insulation — Why It Matters
What sets every Neverdark Thermobox apart from standard bioethanol housings is the quality of its insulation. The steel enclosure is insulated to a level that eliminates the heat clearance distances that standard uninsulated boxes require. A Thermobox can be built directly into a timber-framed wall, integrated into MDF cabinetry, or positioned immediately beneath a television — situations where an uninsulated housing simply cannot be used safely. That engineering is reflected in the price, and it is what makes these installations genuinely flexible rather than just architecturally attractive.
Standard and Hidden Installation
Hidden installation is particularly well-suited to the C2-TST — with no front frame on either face and the top-opening controls entirely out of sight, the installation appears as nothing more than a flame — no visible hardware from either side. Standard installation adds a front frame on the primary viewing face. The control and refuelling panel opens from the top of the unit in both configurations, keeping the front face of the installation completely clean.
