Internal Doors
With a modern and contemporary look and an extensive range of different styles, our collection of industrial-style internal doors adds character as well as function to any room in the home. Industrial-style internal doors make a statement and can also be a great way of adding more light and airiness to a room if you opt for a glazed design.
Our internal doors are available as Steel & “Steel Look” Aluminium. With high-quality and contemporary options available from both product ranges, we can help you create the perfect internal door and maximise the use of space in your home.

Discover TENZO DesignsInternal Door FAQs
Choosing new internal doors is about more than appearance. From materials and glazing to opening styles and installation, here are some helpful answers to common questions.
Choosing Your Internal Doors
What types of internal doors does Sapphire offer?
Sapphire offers three distinctive internal door collections:
- OTIF Steel: Genuine steel-framed doors for a bold, architectural look.
- OTIF TENZO Wood: Oak and glass doors that bring natural warmth and contemporary styling to your interior.
- AluSpace: Aluminium-framed internal doors with a clean, contemporary steel-look appearance.
Each collection has its own character. We can help you explore the options and find a design that complements your home.
What is the difference between steel, oak and aluminium internal doors?
The main difference is the material used for the frame and the look it creates.
Steel gives an authentic industrial and architectural appearance. Oak introduces natural grain, warmth and texture, while aluminium offers a contemporary framed appearance with a different material character.
The right choice will depend on your preferred style, the opening you have and the overall feel you want to create.
Can glazed internal doors make a room feel brighter?
Yes. Glazed internal doors allow natural light to pass between adjoining rooms, helping interiors feel brighter and more connected.
They can work particularly well between kitchens and dining areas, living rooms, hallways and home offices. Glass choices can also help you balance light with the level of privacy you want.
OTIF Steel Internal Doors
What makes steel internal doors different?
Steel-framed internal doors create a distinctive look through their defined frames and glazed panels. They can introduce an architectural feature while allowing light to move between spaces.
They are a popular choice for contemporary interiors, industrial-inspired spaces and homeowners looking for something with a strong visual identity.
Can steel internal doors be made to suit my opening?
The available designs and dimensions depend on the chosen system and configuration. The opening will need to be assessed before the most suitable option can be confirmed.
Speak to our team about your space and we can help establish what may be possible.
OTIF TENZO Wood Internal Doors
What makes OTIF TENZO Wood doors special?
TENZO combines an oak core with oak veneer and contemporary glass detailing. The result is an internal door collection that brings together natural timber character and modern design.
The construction uses a laminated oak core covered on both sides with 2mm oak veneer, creating a consistent oak finish.
What wood finishes are available?
The TENZO Wood collection includes six finishes:
- Latte
- Natura
- Carmel
- Honey
- Smoked
- Chocolate
Each finish gives the oak a different character, making it easier to find a look that works with your flooring, furniture and interior colour scheme.
What glass options are available with TENZO doors?
TENZO offers a choice of glazing options, including laminated safety glass (VSG) and tempered safety glass (ESG), depending on the selected design and specification.
The glass style can make a noticeable difference to the finished look, from a more open appearance to a design that offers greater visual screening.
We can help you check which glass options are available for your preferred door.
Can TENZO doors be made in different sizes?
The TENZO collection includes a range of standard sizes, with bespoke sizing options available within the manufacturer's stated limits.
The suitable size will depend on the door design and selected configuration. Your measurements and requirements can be checked before an order is placed.
AluSpace Internal Doors
What is AluSpace?
AluSpace is an aluminium-framed internal door system designed to bring a contemporary, framed-glass look into your home.
Its clean lines and glazed appearance can help define different areas without completely closing them off, making it an option for open-plan living and modern interior layouts.
Where can AluSpace internal doors be used?
Aluminium-framed glazed doors can be considered for a variety of internal spaces, including room dividers, home offices and openings between living areas.
The most suitable arrangement will depend on the opening, the layout of your home and the system specification.
Measuring, Installation and Advice
Can internal doors be installed in an existing home?
Yes. Internal door projects can be considered for existing homes as well as renovations and new interior layouts. The opening and surrounding structure will need to be assessed to establish the right approach.
Will I need to provide measurements?
You can get in touch with an approximate opening size or photographs to start the conversation. Accurate measurements will be needed before the final specification is confirmed.
Can Sapphire help me choose the right internal door?
Absolutely. Our team can talk you through the different collections, materials and design options, taking account of your home, the space available and the look you want to achieve.
We believe choosing new doors should feel straightforward, with friendly expert advice and no pressure.

BEFORE
I’ve been searching for a while to find the right company and Sapphire windows literally took the vision from my brain and made it a reality. We changed the dining room doors but added a large door to the stairway that previously had nothing. The space now looks incredible. The installation team were prompt, extremely polite and grafted all day. Consummate professionals. I can’t recommend Shaun and the team enough at Sapphire windows
