Porta Impresa has created a new aluminium frame that addresses a major disadvantage of aluminium as a material, namely heat transfer. Special polyamides are used in the new thermally insulated frame in order to prevent this effect.
The door leaf has excellent thermal and sound insulation properties and the gap is sealed along its perimeter with thermally broken aluminium. This door is proposed for external doors of buildings (residences, hotel rooms etc.), as it contributes significantly to energy upgrading.
