Designing the sash-covering front door

Our wooden and aluminium front doors are equipped with a sash-covering panel as standard. But is that really just a question of design? Let us explain to you how sash-covering front doors differ from models with classic insert panels and what advantages they offer you. We will also tell you how security, heat insulation and soundproofing can be improved in your home.


How is a front door constructed?

The structure of a door does not differ significantly from that of a window. Here, too, there is a frame, which is fixed on to the masonry. The movable wing that is hung in it is often referred to as a door panel. This door panel in turn consists of a door frame and an infill. These two elements can be easily distinguished on doors with insert panels, as a visible edge is created.

The front door panel is basically nothing more than a sheet that can be made of different materials. It is largely responsible for the functionality of high-quality front doors, because depending on the stability and features, it determines the level of protection against burglary and thermal insulation.

In addition to the insert panel, there is the one-sided sash-covering front door panel on the outside, the sash-covering panel on both sides and the door panel made of glass. In the case of front doors with glazing, the likeness to windows can be seen particularly well.

Special feature of a sash covering

How do sash-covering house doors differ from other types?

Conventional front doors have an insert panel, which can be recognised by the offset between the sash and panel and has visible sealing edges. The strength of the door panel is slightly less than that of a sash-covering door leaf and is therefore less stable.

With a sash-covering front door, both the door panel and the surrounding sealing edges are covered. The panel is not simply inserted into the frame; instead, it covers the entire surface, which creates the smooth appearance of the door surface that is typical of sash-covering front doors. This type of flush door panel is therefore often referred to as an attachment panel.

It is important that the panel can be fitted on one side or on both sides. In the case of the one-sided variant, the outside is usually designed to cover the sash in order to increase burglary protection. In contrast, with the two-sided version, you can enjoy a smooth surface not only on the outside but also on the inside, which can be visually integrated into modern living concepts much better.


What are the advantages of a sash-covering front door?

Unfortunately, the price of sash-covering front doors is slightly higher than for normal doors. On one hand, they are more complex to produce; on the other hand, a front door with sash-covering infill meets the highest requirements - from design to function. Even the level of maintenance required is lower because there are fewer edges where dirt can collect.

Modern design

As previously mentioned, sash-covering front doors are characterised by their flat surface. This in turn offers much more freedom in terms of design, regardless of whether you are looking for a modern or more classic model.

When you order from us, you get your new aluminium or wood front door with attachment panels on both sides as standard. While an aluminium front door looks more streamlined and minimalist, more traditional designs (e.g. country style) go better with wooden doors. In principle, however, you are free to choose and can select the colour individually too.

Higher burglary security

If the front door is sash-covering on both sides, the door panel is more solid and therefore more stable overall. It does not matter whether you choose wood or aluminium: the door can easily withstand brute force. In addition, the door hinges are not visible from the outside, so that potential burglars cannot find a point of attack for their tools. With a sash-covering door and measures such as additional locks, you can enjoy the great feeling of excellent security.

Improved thermal insulation

Another advantage of the sash-covering filling is the better insulation. With conventional doors, the filling is inserted into the sash and then sealed. With sash covering, on the other hand, the frame is completely covered. In this way, thermal insulation is optimally distributed over the entire front door and heat losses through the sealing edges are eliminated. With the right quality, sash-covering front doors can even achieve values suitable for Passive Houses in this way.
