What does the 'U value' of a material measure?
The thermal resistance of the material
The thermal transmittance of the material
The acoustic performance of the material
The airtightness of the material
Which of the following is true about 'R value'?
It measures the thermal transmittance of a material
Higher R values indicate better insulation
It is used to measure acoustic performance
