Thermadoor

Insulated Sectional Overhead Door

An effective energy saving system.

The need to save energy, stressed by modern building standards, calls for effective insulating door systems.

Yet the insulated door itself is only one element in this system - its value will be lost if the surrounding seals are inefficient, or if it is left open unnecessarily.

Thermadoor systems tackle the entire insulating equipment, making sure that heat stays where it is wanted.
Since this is a long term requirement, all Stertil-Stokvis equipment is of robust quality, designed to give long working life in rigorous conditions.

Every component is backed by well equipped Stertil service engineers, and a good stock of spare parts held by Stertil at Northampton.
