The thermal envelope and vapour barrier, the layer that decides whether the cellar performs, year after year.
Collectors spend their time choosing a cooling system, but a climate unit can only hold what the insulation around it lets it hold. A cellar has to be insulated more thoroughly than the rest of the house, or the system runs constantly and the humidity drifts with the weather.
We build the envelope in Cellarfoam — rigid, moisture-resistant panel with tongue-and-groove edges that lock into a continuous, vapour-resistant face. It delivers a high thermal value in a thin profile, comes in 30, 50 and 75mm thicknesses, and takes plain or textured render for a hard, impact-resistant wall that can be pressure-washed or steam-cleaned without damage.
Insulation is specified as part of the cellar design, not added after: the right thickness for the room, with continuous coverage across walls, ceiling and slab. A vapour barrier and thermal break separate the cool cellar from the warm space around it, so the two climate zones never meet where the dew point can be reached and moisture can form. And it’s designed to match the climate control system, so the envelope and the cooling are sized to work together — and the warranties align.
Product
Cellarfoam rigid insulation panel, tongue-and-groove edge. Sheet size 2250 × 600mm.
Finish
Plain or textured render; hard, impact-resistant. Pressure- or steam-cleanable.
Thicknesses
30, 50 and 75mm.
Vapour barrier & thermal break
Continuous vapour-resistant face with a thermal break, separating the cellar’s climate from the surrounding space so the dew point isn’t reached.
Coverage
Walls, ceiling and slab.
Supply
Supplied as a componentry package, or installed by us as part of a complete cellar build.
Coordination
Matched to the climate control system so the envelope and cooling work together and the warranties align.
If any of the three fail, the others can’t hold the room.
Eleven racking systems, designed in-house and built in our Mornington workshop. The system that suits the room and the collection.
Cellar-specific refrigeration, calibrated to the room and the collection. Sized once, right.
Air-tight, insulated, seen or unseen. Where the cellar begins.
Access to full-height cellars. Timber, sliding, engineered for the room.
