How to seal large gaps in your door

Large gaps in a door can be a huge source of discomfort. Not only is the draught unpleasant, it also causes heat loss and higher energy costs. Many people think that a few extra draught strips are sufficient, but in practice, sealing large gaps requires more than just a standard solution. In this blog, you can read how to effectively tackle large gaps, why it is important to also consider insulation elsewhere in your home, and why the Homebox is an essential component that you should not overlook.

Sealing large gaps starts with tackling all air leaks around the front door, but the letterbox is often overlooked. Draught strips and brush letterboxes only help to a limited extent. The Homebox completely seals the letterbox and is the only solution that is truly draught-free, making your hallway warmer and reducing your energy costs.

When a significant amount of air escapes through a door, your heating system attempts to compensate for this continuously. This can be quite costly. Furthermore, a draughty door is always unpleasant, and many people experience a constant feeling of cold in their home as a result. Sealing large gaps is therefore one of the most cost-effective insulation measures. It is relatively simple and can make an immediately noticeable difference.

Nevertheless, it is still common for people to only seal the gaps and cracks around the door frame, forgetting to look at the bigger picture. A door has multiple air leaks, including the biggest leak of all: the letterbox.

Many draught problems are concentrated around the hallway. This makes sense, as this is where the front door directly borders the cold outside air. This makes insulating the hallway a logical part of a draught-free home. If you seal the gaps around the door but your hallway still remains cold, the cause is often elsewhere. Want to know what you can do about draughts in the hallway? In this blog, you can read how to insulate your hallway.

The first thing you can do when dealing with large gaps is to check the fit of the door. If the door does not close properly, simple draught strips can make a big difference. Rubber strips are suitable for medium-sized gaps, while brush strips often help with small gaps.

However, this is only part of the solution. Once you have decided to seal all gaps and cracks, you need to look at all openings. Most people focus on the door frame, while the letterbox is actually a structurally bigger problem.

A common misconception is that a brush letterbox eliminates draughts at the front door. Although it helps somewhat, it never completely eliminates draughts. A brush always allows air to pass through. In strong winds, air will blow right through it. In addition, brush flaps cannot be closed airtight, which means that heat loss will continue to occur.

For those who are serious about sealing large gaps, a brush strip is simply not enough. It remains a half-measure that only treats the symptoms. In this blog, you can read how to effectively tackle draughts through your letterbox..

When sealing gaps, many people think of strips, sealant edges and insulation panels. But one crucial component is almost always overlooked: the letterbox on the inside. This is where the Homebox comes in.

The Homebox is a fully sealable inner flap that makes the letterbox airtight. It is the only solution that ensures that no air can flow through the letterbox. No brush, no rubber flap, no metal flap can compete with this. The Homebox closes mechanically, making it completely draught-free.

This means that if sealing large gaps is at the top of your list, the Homebox is actually indispensable. Many people seal all the seams and gaps around the door, but leave the letterbox as a large open leak. The result is that the door remains cold, despite all their efforts. By installing the Homebox, you can seal the largest air leak in one go.

Sealing large gaps is one of the most effective ways to live more comfortably and energy-efficiently. Start at the door frame, check all seams and gaps, take a critical look at the insulation in your hallway and don’t forget the letterbox. A standard brush letterbox is never completely draught-free. Only the Homebox truly seals the letterbox hermetically, giving you a draught-free door at last. With the right approach, a warmer and more pleasant home is closer than you think.
