How to insulate the iron front door: professional

Nowadays, many are rightly concerned with security issues. Iron doors can not be hacked without using special equipment. However, this design is able to protect against uninvited visitors, but is powerless against the cold.

How to insulate it without help? We will tell about it in this article. The metal door is a special frame of the profile with a metal sheet welded to it from the outside.

There is a gap of about 8 millimeters wide between the web and the frame. Iron sheet gives off heat to the street, and drafts freely pass through the gaps. Manufacturers often do not take any action to insulate metal doors, but because this occupation falls on the shoulders of the owners of new doors.

Many people are sure that it is enough just to fill the insulation with insulation to solve the problem of insulation. Formally, in fact, it will be considered warmed, but its owner is not interested in formal parameters at all, but in real heat in his living room.

Effective insulation of metal doors, includes, but is not limited to filling with insulating materials. This is just the first step to having truly insulated doors.

Necessary inventory

Итак, перед тем how to warm the front door iron нам понадобятся материалы и некоторые инструменты:

• Foam panels (their thickness must be matched to the thickness of the metal profile);
• Insulating self-adhesive foam rubber (roll);
• Electric jigsaw;
• Sharp knife;
• Battle;
• Set of drills;
• Roulette;
• Emery paper (medium grain);
• Marker or pencil;
• Screws with a drill;
• Отвёртка;
• Sealant, silicone;
• Ruler;
• Sheet of fiberboard;
• Screwdriver or drill;
• The film is self-adhesive under the tree (see. Decor of doors with self-adhesive film will always update the design).

It is necessary to clarify that before starting to perform works on insulation, you need to buy foam with high density. This type of foam is most suitable for creating high-quality insulation.

Getting started

Before insulating the entrance iron door, we draw up a plan of action:

• We measure the height and length of the canvas  together with the width of the profile (see dimensions of the entrance doors). It is necessary that later the screwed fiberboard should completely cover the profile.
• We make a sheet of fiberboard and remove the excess.
• We designate on the sheet of fiberboard space for the eye and the lock (see Installing locks in a metal door: easier than you thought), cut holes for them. Where it is impossible to cut from the edges, it is necessary to drill a hole in diameter, assuming that a jigsaw file enters it.
• Prepared sheet of fiberboard apply to the canvasby checking the correctness of all the holes and cuts.
• We fill the internal cavities with foam panels. For trimming foam use a knife of high sharpness. It is necessary to apply a small amount of silicone on the surface so that the panels do not fall out. Too much silicone should not be used. It will take just enough to keep the panel on it.
• Begin the process of screwing the hardboard. Insert the cue ball into the screwdriver or drill, fasten the screw in it. In the case when the cue ball was not magnetized, we attach some magnet to it for a few minutes.
• We put a sheet of hardboard to the surface and twist the screw through the profile and hardboardwithout drilling any holes. Drills with a screw perfectly drilled holes themselves.

• At the entire perimeter of the profile we tighten the screws at least three pieces per side, and also on the transverse profile. If in some parts of the hardboard does not fit snugly, you need to strengthen the structure with an additional screw.
• After screwing the sheet, we treat the edge of the hardboard with a sharp knife.
• We pass on the edge of hardboard sandpaper (medium-grained) in order to remove bumps and barbs, rounding the edges of the hardboard.

Nuances of iron door insulation

Being engaged in weatherization of the iron door, you need to know a couple of secrets.

Useful advice: When warming an iron door, keep in mind that even small gaps between the foam pieces and the gap between the stiffeners in the door leaf and the foam will need to be filled with mounting foam. It is generally acceptable to glue polystyrene foam to the back surface of the web. The use of foam will allow you to get a higher quality insulation of iron doors.

It is not difficult to warm the entrance iron door, but metal rigidity still remains cold on the door leaf. In most cases, to create stiffness using a profile pipe with a cross section of forty to forty or similar metal. In winter, such stiffness freezes, and at their locations the iron door will let through the cold.

Using foam does not solve the problem. Therefore, in order to insulate the door more efficiently, it will be necessary to fill the installation pipe with foam, which makes up the stiffness on the sheet of the door.

For this purpose, holes are drilled in the profile pipe wall with such a diameter that the spray can tube with mounting foam or the mounting gun tube enters. Holes need to be located about 400 millimeters apart. A tube is inserted into the profile tube, filling it with foam.

Foam wrapping

Foam rubber is the most suitable option when we decide how to insulate the door with the entrance iron door. Some incorrectly believe that the door need to stick rubber for sealing. This is a wrong opinion. In contrast to windows, the door does not have a gap for gluing in rubber, therefore, after gluing the gasket, there will be problems with closing.

The procedure is very simple, done in just two steps:

• We unwind the foam rubber roll;
• Remove the protective film and glue it onto the frame profile as close as possible to the back side. In case the foam sheet is larger along the width of the gap, it is necessary to cut the face at an angle. Cut off one extra facet so that during closing the profile of the door leaf touches and presses into the foam only on the edge of the inside

Repeating all the actions described in this article, you can easily insulate the iron front door on your own.
