Insulation

A process to keep sound, electricity and heat from spreading is known as insulation. A material specially designed to prevent the transmission of heat or sound from one space to other is known as insulation material. The ultimate purpose of insulation is to create a barrier around the building which helps in reduction of the amount of heat loss on a cold day or vice versa. All year round you can keep the desired temperature in your house by the help of insulation.

How does insulation work?

You will need to understand heat flow if you want to understand how insulation works. Heat is transmitted in three different way like convection, conduction, and radiation. Thermal insulation works by restricting the movement of heat in any form providing a much more comfortable place to live in.

The combination of these two characteristics plays a main role in the quality of insulation

  • The natural capacity of insulation material to inhibit the transmission of heat.
  • Natural insulants which are trapped inside the pockets of insulation material.

What is R-Value?

R-value is the measure of resistance to heat flow in a material means the level of heat transfer from warm space to colder space. A material will work more effectively when the R-value of the material is higher. R-value is calculated by dividing the thickness of the material by its thermal conductivity. Therefore, the unit of R-value is m2K/W.

R-values are also the reciprocal of the U-values means the higher the R-value of the material the lower will be the U-value of the material.

R-value is affected by

  • The type of insulation
  • Density of the material
  • Thickness of the material

What is U-value?

U-value is also known as thermal transmittance. U-value is used to measure the efficiency of the insulation material in the construction. The lower the U-value of the material the slower the heat will transmit through the material.

Building regulation has set some standards in part L of the approved document which is mandatory to be achieved while carrying out building work.

What are the types of insulation?

Thermal insulation

Thermal insulation prevents or reduce heat loss and reduces the amount of money and gas and electricity we use to do this. With ever-rising energy costs if the house is properly insulated it can save up to 2/3 of the energy required.

Acoustic insulation

The sound that causes trouble to others is nothing but undesirable an unaccepted sound. Acoustic insulation is also known as sound insulation or soundproof insulation. The purpose of acoustic insulation is to block or decrease the intensity of soundwaves transmitting from outside the house to inside or vice versa.

Fire-resistant insulation

Fire-resistant insulation material slows the spread of fire and protects the building. Fire-resistant insulation material is specially designed to resist high temperature and ensure no toxic smoke is released if it does come in contact with flames.

Fire resistance insulation materials are classified in various ratings as follows

A1- non-combustible

A2- limited combustible

B-F - Low- high contribution to fire.

Insulation materials can be categorized based on various factors like its composition, form, and structural contribution.

Why ventilation is important?

Ventilation plays a vital role when it comes to insulating a space. Ventilation helps to remove harmful substances from the air inside the building also eradicates moisture and provides fresh air inside the house.

A poorly ventilated house can have serious health consequences like fatigue, headaches, sinus congestion, dizziness, shortness of breath, and nausea. On the other hand, it can also damage the walls and fabric of the house with condensation and mould.

What is the importance of insulation?

  • Insulation reduces energy cost
  • Control condensation
  • Improves thermal comfort
  • Reduces the amount of noise
  • Increases fire-resistant of your house
  • Increases the value of the property
  • Increases comfort
  • Protection against fire
