5 best front door heaters

Felt insulation perfectly retains heat in the room. It is produced in sheets and rolls, the raw material for manufacturing is natural sheep wool. With the help of felt, it is possible to insulate both the leafs of metal doors and the boxes of wooden products. Experts highlight several advantages of the material. In addition to being harmless to the human body, the sealant perfectly delays street noise, does not burn under normal conditions, and is resistant to biodestruction. Although felt absorbs water, it retains its insulating properties when wet.

As for the disadvantages, the main one is attractiveness to moths. Therefore, during the production process, the insulation is treated with an aqueous solution (3%) of common salt. Users consider felt to be the best material for insulating the front door in baths. It is only important to ensure that rodents are not interested in them to create a cozy nest.

Sprayed polyurethane is a special type of mounting foam with high thermal insulation properties. With its help, it is possible to completely fill all the cracks and cavities, both in the metal door leaf and in the space between the wooden box and the concrete (brick) wall.For high-quality pumping of foam into the cavity, a special gun is required, with which you can accurately dose the output of polyurethane. Experts speak flatteringly about the adhesiveness of the sprayed insulation and seamless thermal insulation.

Users call polyurethane the best option for thermal insulation of entrance doors. It is not afraid of moisture, does not burn, retains elasticity. Bacteria, fungi, mold do not appear in the synthetic layer. The only drawback is the need to purchase an additional tool.

Mineral wool is a soft insulation with a set of positive properties. The material has the best thermal insulation abilities, it perfectly delays external noise. With the help of mineral wool, it is possible to effectively insulate metal door leaves, close up the slopes of wooden structures. The insulation is popular with apartment owners; use in houses requires an additional layer of polyethylene from the street. This is done to prevent moisture absorption. Otherwise, the mineral wool becomes heavy, its insulating properties deteriorate. And if after that frosty weather comes, then the door will become a source of cold in the house.

Users in the reviews note ease of use, low thermal conductivity, inert attitude to mineral wool of bacteria, insects and rodents. However, this eco-friendly material has a rather high price.

One of the thinnest front door insulation is foil isolon. This material has a two- or three-layer structure. Aluminum foil is glued on the outside, and a layer of polyethylene foam is located inside. Due to the reflective properties of aluminum, it is possible to reflect up to 97% of heat. Low thermal conductivity combined with water repellency. Therefore, the material is used both for the insulation of metal door panels, and for the purpose of eliminating gaps between the frame and the leaf of a wooden structure.

Users note such advantages of foil isolon as high thermal reflection, environmental friendliness, ease of installation and flexibility. The material does not rot, bacteria and insects do not settle in it. The disadvantages of the product include the low strength of the foil, and aluminum tape is required to seal the seams.

In Russia, foam plastic is confidently holding the championship among heaters. The material is supplied to the distribution network in the form of sheets. The user can easily find a product with the required density and thickness. Polyfoam has excellent heat and noise insulation qualities. Experts consider it the best option for warming a metal door leaf. Masters note the convenience of handling polystyrene, it is easily cut with a clerical knife, and it is possible to seal gaps or joints with mounting foam. You can glue the insulation to a metal or wooden surface using liquid nails.

As for the minuses of the material, first of all it is worth noting the crumbliness. Does not like polystyrene to get sunlight on it.But at the same time, it retains water-repellent abilities, neither insects nor rodents appear in it. And yes, it has the best price.
