5 мошеннических приемов при продаже термоизоляции
How thermal insulation sellers and builders deceive you when installing a stove and fireplace.
The article is addressed to those who are building a cottage, or changing the stove in the house, building a bathhouse, or those who already have it.We would like to draw your attention to the most important points when choosing thermal insulation for high temperatures.
And we will be glad if our article helps you avoid wasting time, wasting money and the danger of losing property.
1. Do not trust guest workers and similar builders!
They do not understand that insulating a stove or fireplace is a complex technical issue and a very responsible one.
The results of their work may manifest themselves in a fairly short time, but they will not be around, and there is nothing to ask of them.
The main issue is that insulation should isolate the hot surface from the room and ensure its safety.
The main indicator is the coefficient of thermal conductivity and for almost all materials on the market at temperatures -20 to +20 it differs by no more than 30%, but with increasing temperatures changes begin to occur, and significant ones, in the direction of a sharp decrease in the coefficient, and the most important issue is not saving warmth, but safety. The temperature in the pipe can reach 800º C
FIRST LIE: OUR INSULATION HAS A HIGH THERMAL CONDUCTIVITY AT A LOW PRICE
(at what temperatures is silent).
The operating temperature limits of insulation are important to YOU, and they are a guarantee of YOUR safety from fire.
SECOND LIE: OUR INSULATION HAS HIGH TEMPERATURE LIMITS
(the maximum temperatures for insulation operation are usually indicated, correct, but in addition to the temperature limits it is necessary
know the number of cycles of temperature change from low to high that are possible for the normal functioning of thermal insulation, and this is not indicated. Please note what is written in the certificate regarding the non-flammability of insulation. It must be NON-COMBUSTABLE.
THIRD LIE: OUR ISOLATION HAS SANITARY CERTIFICATES.
Under ideal test conditions, all insulation has sanitary certificates and if the insulation is behind the plaster, then this issue is of little concern to you. But the issue of the presence of binders in the insulation is very important, since this leads to the appearance of combustion products when heated above 150 ° C. You are relaxing by the fireplace, and then you have a headache and why, YOU don’t know. Maybe an extra cocktail? It’s just that the combustion products released are not felt by YOU, but they affect YOUR well-being.
FOURTH LIE: THEY ARE NOT TELLING YOU ABOUT THE SERVICE LIFE OF THE INSULATION.
Or they vaguely hint at decades, without taking into account the number of cycles of temperature change from heated to cooled. Binders are destroyed by temperature and time, and the insulation crumbles every year. Service life depends on the manufacturer and material, but the loss of the guarantee of YOUR safety from fire is a critical issue.
YOU already have so many problems, why do YOU need to think about another one?
FIFTH LIE: OUR ISOLATION IS CHEAP.
If you count it per meter or kilogram, then it is possible. But the first costs are installation, then after a few years - reinstallation and purchase of new insulation, but, most importantly, due to insulation that has lost its qualities, there is a possibility of loss of property. You think that YOUR pipe is insulated, but in reality the insulation no longer works - it has crumbled.
And you can’t trust builders to buy insulation in order to increase their income; they will buy the cheapest one or simply put less layer under the coating than necessary. You can avoid such problems by working with companies that provide a written guarantee and have a long reputation.
THE FIRST PATH IS THE HARDEST
Study this issue yourself to the level of an expert (long, expensive, not interesting)
THE SECOND WAY IS NOT CHEAP, BUT SIMPLE.
Place the following material in critical areas with high temperatures:
- with a high thermal conductivity coefficient at temperaturesover 400 º C - Supersilika
- without binders - Supersilika
- consisting of fibers thicker than 6 microns - Supersilika
- with a service life of more than 30 years in conditions up to 800 º C without limiting the number of thermal cycles (operating temperature 1000-1100 degrees C) – Supersilika
We find solutions for any problem.
Just tell us about it!
