Is it difficult for an untrained person to use Polynor?
Nothing like this! Polynor is the easiest and most affordable insulation to use. You don't need to have any special skills to use it. All you need is a regular gun for polyurethane foam and a Polynor nozzle for spraying, supplied with each cylinder in the kit (Polynor 3D has 2 nozzles in the kit - a regular one and an angled one for horizontal surfaces).
Is it polyurethane foam?
With external similarity, products are completely different in purpose, properties and characteristics. Polynor has a low water absorption coefficient, predominantly a closed-cell structure, does not shrink and remains elastic, adheres completely (without gaps) over the entire application surface. Polyurethane foam cannot be applied to the surface with a wide torch like Polinor, there is no foaming.
what square does one can heat?
From one Polynor can with a layer thickness of 30mm, up to 2 sq.m comes out (if the instructions are followed).
In one pass, you can apply a layer from 1cm to 4cm, apply in 20 minutes increments to the previous one, the number of layers is not limited. The layer thickness is controlled by the application speed.
We recommend applying in several layers, first the first layer 1.5-3 cm, then after 20 minutes the second layer up to 4 cm, depending on the desired final thickness of insulation, which will correct the shortcomings of the first layer and provide seamless heat / wind protection.
What is the difference between PolYnor and other sprayed heaters?
The Polynor formula has been developed and tested for several years. The product itself has been produced since 2014 and during this time there have been no complaints. All other "sprayed" heaters are ordinary polyurethane foam, they are characterized by: low foaming, the impossibility of applying to the roof or ceiling, holes inside the insulation, lack of adhesion (sticking) and the worst thing that you do not see is incomplete adhesion on the surface (dew point in the wall).
Beware of fakes, so as not to get a problem in the form of poor-quality insulation (fungus, mold, freezing, and so on)!
Is it possible to insulate the living space with Polynor?
Polynor fully complies with the uniform sanitary-epidemiological and hygienic requirements. Allowed for heat and sound insulation of apartments, attics, cottages, verandas, loggias and so on. Certificates
Environmentally friendly? Does it attract rodents and insects?
Absolutely environmentally friendly (biologically inert material), does not react with water, air, cold or heat in the range from -80 ° C to + 121 ° C. Does not contain freon, formaldehyde and other harmful substances.
Rodents and insects are neutral towards Polynor. Certificates
Why is POLYNOR so expensive?
Often, the choice begins with a low cost of insulation, the calculation often does not take into account the cost of additional materials necessary for the correct installation of the insulation. As a result, the final cost of the insulation is much more expensive than the initial cost of the insulation on the store shelf.
In fact, the total cost of insulation by Polinor is at least no more expensive than other types of insulation, which initially have a lower price on the store shelf.
The principle of choosing a heater should be based not on its cost and the manufacturing company, but on its technical characteristics and taking into account all additional costs.
What are the advantages over extruded polystyrene foam and mineral wool?
With Polynor you don't need:
Can be applied to wood?
Unlike Styrofoam and extrusion foam, it fits perfectly with wood. Forms a monolith with a surface, which excludes the penetration of moisture and the formation of a nutrient medium for the appearance of fungus and mold. The wood won't rot.
I'm afraid of the dew point, where will it be when insulated by Polynor?
When insulated from the outside or from the inside, the dew point in both cases will be in the insulation. There will be no condensation. Condensation forms when warm air collides with a cold surface.
From the inside - the outer layer of Polinor (contact with the wall) will be the same temperature as the wall and, accordingly, there will be no condensation.
Outside - the inner layer of Polynor (contact with the wall) will be the same temperature as the wall. There will be no condensation.
Of course, this all works with a sufficient thickness of insulation.
does Polynor afraid of water?
No, Polynor does not react when water gets on it, vapor permeability and water absorption tend to 0. Of course, if Polynor is constantly in the water, he will pick up water over time.
What is the density?
19 - 25 kg / m3 at a temperature of 22 ° C and a relative humidity of 65%.
Flammability? Does it melt when burned and release something harmful?
Polinor does not support combustion. Flammability group according to GOST 30244-94 - G3 (normally flammable).
If it is necessary to reduce the flammability group to G1, Polyguard fire protection is applied (applied to only released Polynor, within the first 5-8 minutes after application, consumption - 1 liter per 10m2).
Cannot be ignited with a gas burner.
What materials can be applied?
Polynor is a unique insulation and can be combined with all building materials, with the exception of membranes and films.
Can be applied to steam and waterproofing films?
No, because they are not rigidly fixed to the surface.
Can it be used as waterproofing?
Polynor is not a complete waterproofing solution that stops leaks in roofs or walls.
Can it be used as sound insulation?
It is possible, the sound absorption coefficient is 55dB. It is difficult to understand the significance of the coefficient - watch and listen to live examples.
How fast does it dry?
Skin formation - 4 min.
Curing speed (time between coats) - 20-40 minutes.
Complete polymerization occurs within 24 hours.
At what temperatures can it be used?
Surface temperature from + 5 ° С to + 30 ° С.
The temperature of the can is from + 18 ° C to + 25 ° C.
Can I pour into voids?
It is possible, but only between rigid materials (concrete, brick), in order to exclude their extrusion by the product.
Which gun is suitable and where to buy a spray nozzle?
Almost any professional gun for polyurethane foam is suitable for the nozzle that comes with each can in the kit, the main thing is that the nozzle fits tightly and does not dangle on the seat of the gun. When spraying, the product must not come out from under the nozzle. If you do not want to waste time on selecting a gun, we recommend using a proprietary Polynor Premium Gun
Do I need to wet the surface before / after spraying?
Before applying, moisten only porous building materials, such as: brick, foam blocks, gypsum, concrete, wood. Smooth surfaces such as metal, glass, etc. - do not get wet. Thoroughly degrease galvanized metal and profiled sheet before use. It is recommended to lightly moisturize on top of the released Polynor, within the first 8 minutes
Do you need to cover / sheathe the sprayed surface?
It is necessary to cover from UV radiation with a finish or paint (except for water-based and acetone-containing ones).
Do I need to leave a gap between the Polynor and the skin?
Need to. POLYNOR is a closed cell polyurethane foam, therefore expansion of the insulation layer is allowed when heated. It is necessary to leave a gap of 2-3 cm between the surface of the cured insulation and the final finish.
How to apply correctly on smooth galvanized sheet?
We do not recommend applying on galvanized surfaces if you do not fully follow the instructions. The procedure for applying to zinc is as follows:
What is the technology of using Polynor for external wall insulation (wood, brick, concrete, foam blocks)?
Polynor eventually collapses from ultraviolet radiation, so it will be necessary to close Polynor in the future with siding, panels, imitation of a bar, etc.
1 - It is necessary to fix the guides on which siding or other finishing materials will then be installed.
2 - Moisten the wall a little and spray according to the instructions. Leave a 3-5 cm gap between the panels and the insulation. Polinor has a closed cell, therefore, a slight expansion of the insulating layer is possible when heated.
3 - Can be sewn with panels 24 hours after spraying.
Can I plaster?
We do not recommend plastering outside, since Polinor has a closed cell, which expands slightly when heated Inside, you can plaster, preferably using thermal plaster.
How are Polynor and Polynor 3D different?
Polynor 3D has an improved formula and can insulate a large area, 1m2 with a layer of 6 cm.Also with Polynor 3D, in addition to the usual nozzle, a special corner nozzle is supplied for horizontal surfaces (floor / ceiling)
