Internorm is the leading provider of commercial doors in Europe. We offer our wide range of doors for commercial buildings across the UK, and our versatile designs can meet any specific needs. Each of our doors can meet Passivhaus standards, meaning your building will achieve leading levels of thermal efficiency and noise reduction. And, with Internorm's modern technology, you'll benefit from increased security for your next commercial project too.
We offer a wide range of commercial doors for any project. You can explore our selection of aluminium entrance doors, timber-aluminium entrance doors, and even our lift and slide doors, all available in a range of profiles.
If you need security for your next commercial project, our doors can provide it. Our aluminium and timber-aluminium entrance doors have highly durable cores, making them robust and resilient. Because of this, these doors can cope with forced-entry attempts. And, with advanced locking mechanisms, they’ll also resist modern burglary techniques.
Additionally, we fit all of our commercial doors with leading I-tec technology. I-tec makes your doors smarter, meaning you can react quicker to any potential threats. Not only that, our aluminium and timber-aluminium entrance doors are easy to care for, as are our lift sliding doors. With durable materials across the design, they can last for decades without maintenance.
Internorm’s commercial doors can also give your new building a feeling of space. We make sure all of our doors come with double glazing panels that offer excellent views of the world around you. For example, our lift sliding doors are almost fully glazed, breaking down the barriers between inside and outside.
You can also design our doors to suit your architectural vision. At Internorm, we design and supply all of our commercial doors to your order, meaning you can easily create bespoke designs for your project. Our aluminium doors come in several stylish colours, and our timber-aluminium doors can feature sustainably sourced spruce, larch, oak, ash and walnut wood types.
With commercial doors from Internorm, you’ll create the commercial building of the future. It’s because many of our doors meet Passivhaus standards, meaning they achieve market-leading U-values of lower than 0.8W/m2k. Passivhaus doors also improve noise reduction, creating an ideal commercial environment for office spaces, retail areas and hotels.
Internorm offers premium grade commercial doors for businesses across Europe. We design and manufacture our products in Austria to make sure each one meets our quality standards. Rest assured that your doors will be expertly manufactured to your needs. We also offer a wider range of window or door systems which are factory fitted to save your business time and money.
Internorm’s innovative commercial doors have received industry-respected accreditations such as Secured By Design, BBA and Saint-Gobain. Our doors provide luxury and comfort while also ensuring strength and security, creating the ideal balance for commercial buildings. We also offer a fifteen year product warranty across our range of commercial doors for your peace of mind.
You can design all of our commercial doors to be bespoke to your next project. Internorm’s design process ensures you can order a unique door with ease, and our team will be your trusted partner in achieving your architectural vision. All of our aluminium, timber-aluminium and lift sliding doors come with unique features to help you realise your project’s potential.
At Internorm, we value the way we treat our customers as much as our commercial doors. You will get an outstanding service for each order you make with us, and we’ll help you with anything you need from start to finish. We cater to all types of commercial products and services.
