Aluco aluminium internal doors – better designed and made

The redesign of our new Aluco internal doors, part of our Interior Collection, starts with engineering and aluminium profile quality. Where other competitor doors feature hollow ‘box section’ frame profiles, our doors are designed with multiple profile chambers with thicker aluminium profiles. You benefit from stronger and better-built doors. Moreover, our doors used day-to-day, feel solid and reliable and never light and flimsy.

The significant benefit of the new Aluco internal aluminium door is the improved design and more advanced construction. In addition to the stronger and better multi-chambered profiles, our doors are made around the glass. Unlike the unglazed manufacturing method of other doors, making the doors around the glass not only results in a better-made and finished door but also one that is tighter, more robust, and substantially stronger.

The way we build our doors is similar to high-end aluminium sliding doors also made around the glass in the factory. We think this is the best way to give you a complete product that is fully checked across every stage of its production, right down to ensuring the glass fits right, sits correctly and is an integral part of the entire door set.

And just like the entire Aluco range of products, all feature quality aluminium extrusions, professionally applied colour finishes and the most beautiful door handles, making an Aluco product a joy to use daily for you and your family. Here are some more unique features you only get with an Aluco door.


When comparing our new Aluco aluminium internal doors to the other internal door products, ours are the slimmest.

You’ll find our doors more than 15% narrower than competitor products at the all-important sightline between the edge of the door frame to the glass line. You benefit from doors that look more like steel doors, with more glass and less visible frames.

We’ve even slimmed down the feature lockbox and handle backplate, making it smaller and to the smaller size of genuine steel.

wraparound sash design

Only Aluco aluminium internal doors have the wraparound sash design. This means the doors are made in our factory around the glass.

This design has numerous benefits. Most important is that our doors don’t rattle because the glass is part of the construction and is not fitted after the doors are made.

This more complex way of making your new doors also means they’re stronger, the glazing beads are fitted in our factory, and the entire construction give you better, and longer lasting doors.

Another significant design change is how Aluco aluminium internal doors now overlap the slimmed-down frame when closed. This design feature is, of course, found on exterior quality steel-look doors.

Other aluminium internal doors are designed to sit centrally and look flush when closed. One drawback to this is that closed doors can rattle. Our new overlapping design keeps your doors firmly shut when needed with no risk of rattling because every part of the door sash rests against the frame.

The advantage of this new and improved design is that your new doors look similar to steel doors that also are designed to overlap the frame.

Another new feature designed for our doors is their ability to go taller.

The new Aluco aluminium internal doors are capable of substantially larger sizes when you want big doorways without needing a fixed glazed panel above. Bigger doors, more light, more glass and a more spacious feel to your rooms.

In fact, the only other door that can go as tall or taller as an Aluco door is a steel door!

better sealing, quieter rooms

Only Aluco aluminium internal doors are designed with a unique double seal.

As your doors close, you feel the positive closing action as the door sash closes onto its specially designed door seals.

The result is doors that don’t have the metal-to-metal feel of other doors but close with a reassuring soft close. The double seal also ensures less noise transmission between your rooms.

The appeal of a classic metal door in the industrial look, Art-Deco or Heritage style is all about symmetry and balance. What better way to achieve this than give you an identical appearance whether you are standing inside or outside your room?

The new Aluco aluminium internal doors feature a unique centralised glazing design. The benefit is equal depth to the door shoulders on each side.

No other aluminium door has this ingenious design feature, where you’ll always find one side of the door thicker than the other or the glass flat against the edges on the one side and a thick aluminium sightline behind.

multi-chamber frames, even stronger doors

Aluco aluminium internal doors are designed not just to last for years in your home, but to also withstand high-traffic buildings such as restaurants, offices and other commercial buildings.

The frame design of Aluco doors is so strong, because unlike other internal aluminium doors, it’s not just a basic solid door frame. We’ve integrated multiple internal chambers to make our doors as strong as they can possibly be.

You benefit from doors that are built to last for decades.

Our new Aluco aluminium internal doors also come in our unique floating lock design, giving you what is genuinely the slimmest fully glazed aluminium door on the market. Only steel doors are thinner.

Floating lock doors are our own design and creation and again, only steel doors offer this option, where the feature lock body floats into the glass line.

These doors give you the option of a fully glazed door or one with 20mm steel-look glazing bars,

Even more benefits you only get with Aluco aluminium internal doors

The improved Aluco internal doors now take thicker single glazing, providing an even better door. 6mm toughened safety glass is standard, with up to 6.8mm laminate or 7mm single glazing available.

Both our internal and external door systems give you the biggest choice of glazing bars. You can choose the ultra-slim steel-like 20mm bar, 25mm bar or the 33mm transom for a bolder-looking door.

Like steel doors, Aluco double doors are designed with the feature lock body on the primary door only. Or you can opt for a symmetrical look with the feature lock body on the secondary leaf as well.

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
