The main advantage for a Triotherm insulated door upstand is, to achieve the optimal energy efficiency and thermal comfort in your building.
A few decades ago, the focus for door upstands was only on the structural support of the door or window-down-to-floor. At that time, there was no great ecological awareness and the prices for heating oil or gas were significantly lower than they are today. Thermal bridges were an alien concept for most people back then.

The thermal insulation properties of our buildings have been continuously improving for around three decades. Energy costs have risen in roughly the same way, which is why we need to be as efficient as possible today.
It is therefore extremely important nowadays that a door upstand has good thermal insulation in addition to its structural support properties. Concrete is completely out of the question here.
Here's why you should consider using a Triotherm insulated door upstand:
Improved Energy Efficiency
Triotherm has a thermal conductivity of around 0.040 W/m²K. A thermal block has a thermal conductivity of around 0.34 W/m²K, which is almost nine times worse than Triotherm! The thermal conductivity of concrete is between 1.33 W/m²K and 1.95 W/m²K and thus at least four times worse compared to the thermal block. If we compare the thermal conductivity of Triotherm versus concrete directly, Triotherm insulates at least 33 times better than concrete!
Eliminates thermal bridges
Triotherm door upstands prevent cold bridges, which are areas where heat can easily escape your building.
Such a thermal bridge is created even if the concrete door upstand fitted with an additional vertical insulation layer on the inside. As the thermal insulation of the door frame is worse in comparison to an insulated wall or floor, heat flows outwards through the door frame and the concrete upstand.
Reduces heat loss
By effectively insulating the area beneath your door, you minimize heat transfer, leading to lower energy bills. As Triotherm has better insulating properties than any currently available door (or window), there is no further heat loss through the door upstand.
Enhances overall building performance
An insulated door upstand contributes to a more energy-efficient building envelope. The basic principles for this are a continuous insulation layer and the minimising of thermal bridges.
