Thermal barrier technology
The REAL Aluminium window and door range is enhanced with innovative polyamide thermal barrier technology, enabling the windows and doors to exceed the energy performance requirements of current UK Building Regulations.
The polyamide thermal barrier reduces heat loss and enhances the overall U Value of a product, allowing REAL Aluminium casement windows to achieve a Window Energy ‘A’ Rating when used in conjunction with the correct double- or triple-glazed unit.
