insulation of the floor best underfloor insulation method

Floor insulation of residential buildings is a very important issue , with no loss of heat through the floor can reach 20 % of the total heat loss . Thermal insulation materials used in this case for insulating floors over cold cellars on the ground floor , with underfloor heating. The main requirements for thermal insulation material at this stage of construction is the ability to withstand a long period of time, static and dynamic loads , and high resistance to moisture and heat loss . The least of the fact that the floor insulation , by reducing the thickness of the insulation layer of the floor can significantly increase the height of the room .

The basic material for thermal insulation of floors is an extruded polystyrene foam, it is placed on a concrete slab , so when planning insulating floors over cold cellars , underground and driveways should not require the waterproofing layer . This leads to cost reduction and reducing the amount of work . Thus in order to increase the thermal insulation properties of the need to avoid overlap joints of concrete and insulation boards .

If thermal insulation of floors on the ground need waterproofing . In this case the material is deposited on the concrete surface as well as on sandy preparations . Its insulating properties increase due to the stepped edge of the board , also known as the selected quarter .

When the device is underfloor heating main purpose of insulating material is the exclusion of heat transfer in the direction of the underlying space. Thus in areas with high humidity levels to protect the heating elements needed waterproofing layer .

The use of modern materials for floor insulation

The use of modern insulating materials in construction can not only reduce the cost of it, but to make it less time consuming. The quality of housing built or renovated using insulating materials is much higher than the quality of the buildings with the ” naked” floors and walls. Thus, floor insulation greatly increases the assessed value of property that pays for the cost of the laying of thermal insulation materials .

Thermal insulation on the floor joists using Minplita

Thermal insulation on the floor joists with insulation wooden house is located in the space between them and does not feel strain. For insulating the floor of the first floor of the house can be applied insulation of mineral wool density is not large ( 25-45 lbs. / Cubic meter ) . Most preferred is a basalt mineral wool insulation . These heaters are non-flammable , with insulation have very low water absorption . The use of fiberglass insulation for thermal insulation requires special care to perform waterproofing, vapor barrier , because its water absorption at warming is high. Foam insulation of the floor is limited to the requirements of fire safety. The foam is flammable . Moreover, while the first floor slab insulation foam can be damaged by rodents. The use of extruded polystyrene foam insulation is usually not economically feasible , unless you want to minimize the thickness of the layer of insulation .
