As part of the façade, doors are exposed to the elements, with timber being particularly susceptible. The solution: A durable aluminium casing protects the outsides of the door frame and the door leaf. But the intelligent composite system of wood, high thermal insulation foam and aluminium offers even more advantages. Internorm timber/aluminium doors are ideally suited to the highest demands such as low-energy houses and passive houses. The aluminium surface on the outside is also low-maintenance and available in various colours. On the inside, wood or phenol gives the desired natural, cosy look.
- Great choice of colours for both the inside and outside
- Various design and fitting options
- Optimum thermal insulation values
- High level of security with resistance class RC3
