Steel joinery has always been a synonym of modern interior design. With the growing popularity of the so-called loft apartments, it has become an inevitable element used by all minimalist interior designers in their work and projects. Loft style apartments, generally associated with the lack of interior walls and very high ceilings, seem to be perfectly complemented by steel windows and doors. Nowadays, such raw and industrial home interior design, popularised by many movies and TV series, is very aspirational and highly desirable.
Why is minimalist interior design so popular
The popularity of minimalist interiors can be explained with one word: simplicity. In the world full of distractions and constant chaos, our senses desperately need to relax in a calming environment. We want to be able to focus on the things that really matter and thus, we willingly remove all the unnecessary and overwhelming details that clutter our living space. In room interior design, it means getting rid of excess furniture, home accessories or ornaments and leaving only the most important ones. You have to admit that from this perspective, minimalist house interior design seems to be quite budget-friendly, doesn’t it?
Among all modern interior designs characterised by minimalism and simplicity, loft design ideas are surely trending nowadays. Minimalist loft is characterised by a plenty of open space and industrial elements in decor, such as very high ceilings, brick walls and large metal-frame windows. Surely the main purpose of this interior design type is preserving the feeling of openness. Such a large, flexible open space with high ceilings and huge spacious windows is obviously a big advantage. However, in order to make loft space more functional, you may sometimes need to insert partitions. If the rooms in your modern and minimalist house or apartment need to be properly divided, think of the partitions made of a transparent material – or just use big sliding doors. Such a solution would help you retain an open plan sense and at the same time, achieve some privacy, adding an eye-catching design element for your modern home interiors.
The best window styles for loft interior
As a loft is usually a former industrial or manufacturing space that has been converted to the residential one, it requires windows that harmonise well with metal elements, such as visible pipes or structural columns. For this type of home interior, raw, minimalist-looking solutions would prove the most beneficial – namely, steel windows. The steel frames fit in perfectly with the trend for an industrial style and offer a huge range of opportunities for modernising the style of any property. 
Slim windows made of steel add minimalist sophistication to room interior design, as they perfectly combine timeless charm and contemporary elegance. But most importantly, they let in a lot of natural light. As steel is an incredibly strong material, even the slimmest frames can support large glazing. Consequently, your loft interior will be beautifully flooded with light, retaining its inimitable industrial-chic aesthetic. If you want to maximise the effect of simplicity and minimalism in windows, choose between shades of grey, anthracite or put on windows in a completely black look.It is also worth mentioning that steel windows are a popular option for properties of architectural note. They help to preserve the original appearance of historic houses and can be used to replicate original joinery for both listed buildings and properties in conservation areas.
How to choose minimalist interior doors
The best minimalist doors for industrial-style spaces are structures whose primary material is metal and glass. Such doors should provide the loft interior with a lot of clarity and freshness, and most importantly, give access to natural light. In order to create a sense of spaciousness and comfort in your home interior, choose internal steel door systems characterised by the high transparency of the glass elements, such as Internal Steel Doors Presto XS or Internal Steel Pivot Doors Norm Pivot. 
Above all, loft doors should be a highly functional solution for people wanting to separate the living space without giving up access to light. From this perspective, steel sliding doors are the best possible choice. They don’t block the flow of light, but help to create cosiness by separating areas into smaller spaces, for example a kitchen from a living room. Internal Steel Sliding Doors Norm Slide will be highly useful in a modern house or loft as they can serve as partitions to create a clear yet unobtrusive separation between two rooms. Norm Slide will help to create a unique, industrial interior design in all the residential spaces where it is not possible to install traditionally opening doors.

Steel-look windows and doors mimic the industrial style of traditional steel joinery, but are often made from aluminium or composite materials. Their slim black frames, minimalist design and clean lines make them ideal for modern and loft-style interiors. These systems offer the visual impact of steel with better thermal performance and flexibility.

Steel profile systems also ensure high stiffness of the window structure that is comparable with that of much thicker wooden and aluminium profiles.However, it is often believed that steel frame windows and doors are unsuited for domestic usage. Although steel obviously looks smart, it is a poor conductor of heat, which means it gets very hot in the summer and very cold in the winter. house.
