ThermaSkirt vs Trench Heaters
Trench heating requires excavating deep channels into your floor screed exactly at the boundaries of your external doors, dropping in a heating coil, and covering it with a metal grille. While effective at blocking drafts from large windows, it is an engineering nightmare to retrofit. ThermaSkirt achieves the identical thermal curtain effect entirely above ground, projecting just 20mm from the adjacent walls.
Excavation vs Integration
The fundamental problem with trench heaters is the physical space they require in the substrate. Excavating a 200mm deep trench across the entire length of your expensive new bi-fold doors involves severe structural coordination with architects and builders. They also present extreme levelling challenges when joining different floor finishes up to the metal grilles.
ThermaSkirt eliminates the trench entirely. Driving heat via an aerospace-grade aluminium extrusion, it can be mounted flush against the plasterboard adjacent to the doors, or wrapped seamlessly around the kitchen island. By emitting a continuous curtain of radiant heat at low levels (35-45°C for heat pumps), it intercepts and neutralizes the cold drafts rolling off the glazing before they sweep across your room, without requiring a single inch of concrete to be cut.
