Configuring your new Aluco internal doors.

The first consideration for designing and configuring Aluco internal doors is the size of the doorway. The options for designing your doors to suit the required aperture include:

Single doors

Single doors are great for standard-size doorways, new or existing. Wider and taller door openings can have additional side and top panels, creating a larger glazed area whilst retaining the same size of door.

Double doors

Where the size of the opening requires a double door design, our Interior Collection of steel-inspired doors, provides stylish, doors with the option of opening one or two of the door leaves. Just like single doors, these too can be designed with optional side panels and top-glazed panels.

For the purposes of this article we are focusing on how to design hinged internal Aluco doors but do check out the sliding door option available.

Aluco doors come as open in or open out designs.

Bespoke designs with doors and screening

Also available when considering the design of internal Aluco doors is how you can create larger glazing combinations.

Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.

So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
