Top 5 best front door insulation
Metal entrance doors reliably protect an apartment, house or commercial building from burglars due to the steel sheet thickness from 1.0 to 4.0 mm. Such an obstacle is more difficult to crack by force. But due to the increased thermal conductivity of the metal, the housing will cool faster, so you need a high-quality filler, which is important to equip the door leaf with.
When choosing a door insulation, it is important to pay attention to several factors.
- The material must have a low thermal conductivity. This quality is especially important when insulating the entrance doors of private houses, summer cottages and garages.
- Resistance to various negative influences is highly valued. Insulation should not lose its quality over time, it should be fire and moisture resistant. In addition, resistance to biological damage, unattractiveness to insects and rodents is welcomed.
- High-quality insulation of doors can be done with insulation, which has elasticity, lightness, ease of installation.
- Not the last place when choosing is the availability of a door heat insulator. This applies not only to the price, but also to the wide presence of the material in the trade network.
Rating of heaters for the front door
5 Felt sheet
Felt insulation perfectly retains heat in the room. It is produced in sheets and rolls, using natural sheep's wool as raw materials. With the help of felt, you can insulate both the canvases of metal doors and 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 biological damage. Although the felt absorbs water, it retains its insulating properties after getting wet.
As for the disadvantages, the main one is the attraction to moths. Therefore, in the production process, the insulation is treated with an aqueous solution (3%) of sodium chloride. Users consider felt to be the best material for insulating an entrance door in saunas. It is only important to make sure that rodents are not interested in them to create a cozy nest.
4 Cork agglomerate
This insulation is made from shredded tree bark, which is pressed into slabs at a temperature of 350 degrees. Thanks to this technology, there is no need to add adhesives and other chemicals to the composition - there are enough natural resins in the wood to bind. The result is an elastic material with good recoverability after bending or compression. Cork agglomerate for entrance doors can be purchased in thicknesses of 10, 15, 20, 25, 40 or 50 mm. The masters in the reviews like the ecological cleanliness of the insulation and the ease of cutting. But they advise to "plant" the insulation on the glue for better fixation. The thermal conductivity of the agglomerate is 0.040 W / mK, which is almost as good as mineral wool. It can be operated at temperatures from -180 to +110 degrees.
3 Mineral wool
Mineral wool is a soft insulation with a set of positive properties. The material has the best thermal insulation properties, it perfectly absorbs external noise. With the help of mineral wool, it is possible to effectively insulate metal door leaves, close up the slopes of wooden structures. Insulation is popular with apartment owners; use in houses requires an additional layer of polyethylene from the side of the street. This is to prevent moisture absorption. Otherwise, the mineral wool becomes heavy, its insulating properties deteriorate. And if frosty weather comes after that, 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.
2 Foil isolon
One of the thinnest insulation materials for the front door is foil-clad isolon. This material has a two- or three-layer structure. On the outside, aluminum foil is glued, inside there is a layer of foamed polyethylene. Thanks to the reflective properties of aluminum, it is possible to reflect up to 97% of the heat. Low thermal conductivity combined with water repellency. Therefore, the material is used both for insulating metal door leaves and for eliminating gaps between the frame and the door leaf of a wooden structure.
Users note such advantages of foil-clad 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.
1 Styrofoam
In Russia, the championship among heaters is confidently held by polystyrene foam. The material is supplied to the distribution network in the form of sheets. The user will easily find a product with the required density and thickness. Polyfoam has excellent heat and sound insulation qualities. Experts consider it to be the best option for insulating a metal door leaf. Craftsmen note the convenience of handling foam, it can be easily cut with a clerical knife, and it is possible to seal the cracks or joints with polyurethane foam. You can glue the insulation to a metal or wooden surface using liquid nails.
As for the disadvantages of the material, first of all it is worth noting the crumbs. Doesn't like foam plastic getting sun rays on it. But at the same time, it retains its water-repellent ability, neither insects nor rodents appear in it. And his price is the best.
