INSULATION PRINCIPLES: THERMA PRINCIPLES

INSULATION PRINCIPLES: THERMA PRINCIPLES

Heat is energy! Heat is a form of kinetic energy that moves from a hot area to a cold area. For insulation the flow of heat is broken down into Thermal Values:

THERMAL RESISTANCE (R)

Yes, 70% of your heat entering a building comes through the roof, and during the winter months, more than 60% of your heat loss is through your roof.

  • The thermal resistance that a specific thickness of material will provide is given by: R = t/k mk/W, where t = thickness.
  • The higher the better the Thermal resistance.

THERMAL TRANSMITTANCE (U-value)

  • The U-value of a building system is the heat flow through the system per square meter for each degree Kelvin temperature difference across the system. It includes the co-efficient of thermal resistance of all surfaces of the system and the thermal resistance of the individual layers (i.e. external air space, roof sheets, ceilings etc) and can be calculated as follows:
  • Ut =_____________1______________where R is the resistance of each layer or surface. R1 + R2 + R3 …. Rn

SYSTEM R-VALUE

  • Is the combination of all the R-Values (including all air gaps, materials etc)
  • The higher tho R-Value the better the insulation

FIRE LEGISLATION

  • SANS 428 Fire Standard, a new standard that ensures that all insulation products are correctly classified to adhere to the new fire standards.
  • All Youngman products comply with SANS 428.

ACOUSTIC PRINCIPLES

Acoustic design is generally overlooked when designing a building. Internal Acoustic design; sound absorption within a building, which improves working or living conditions, assists school children to concentrate etc. Roof Acoustic design; for sound transmission loss, from rain and wind noise. NRC value also assists. Two types of values that make acoustics important;

  • NRC, Noise Reduction Co-efficient which is the absorption of noise, the worst value is 0 and the best is 1, if the value is 0,5 it means that 50% of the noise is absorbed.
  • STL, Sound Transmission Loss is measured in Decibels (Db).
  • The higher the Db the better the product.
