Bring your vision to life with our innovative Door Designer tool. Experiment with styles, colours and finishes to create a unique entrance door that complements your home, enhances kerb appeal and delivers exceptional security and performance.

Choose from aluminium, timber-aluminium or timber-composite doors. All offer outstanding thermal performance, and any array of colours, finishes, designs and handles to suit any home, from traditional houses to contemporary architectural masterpieces.

Powered by sunlight, Internorm's I-tec Shading is available with all Internorm timber-aluminium and uPVC-aluminium windows featuring accessible, integrated blinds. Operating independently of an external power supply, the system uses an integrated photovoltaic module and rechargeable battery to deliver convenient, energy-efficient shading.

Shading does not just provide privacy but also prevents your home from over-heating. With ever increasing summer temperatures, all Internorm shading solutions offer comfort throughout the year.

Create striking contemporary spaces with Internorm's innovative glazing solutions. From frameless windows and glass-to-glass corners to large lift & slide doors, panoramic glazing and bespoke designs, we offer tailored solutions for even the most ambitious architectural projects.
