 Summer heating

Entreprise Moulin, our commitment to sustainable development

Regarding the summer heating, the capacity of your isolation to accumulate heat will determine the length of the « phase shift ».

These are the qualities that will help you to save on cooling your home. It is certain that the choice of materials will be crucial in the energy savings you will realize ;
However, the design and behavior of the inhabitants are equally important factors for the responsible management of energy costs.

Phase shift is :

• the time in hours it takes for a material to release the accumulated heat
• or
• The capacity of accumulation of this material ( Wh/m3K)

Phase shift is related to the density of the material. Higher it is, better is your protection against summer heat.

Phase shift materials examples:

Material for 20 cm	Presentation	Thermal conductivity (λ)	Phase shift
Wood fiber	Flexible panels	0,039	7,5 to 11 hours
Cellulose	Flexible panels	0,039	12 hours
Cellulose at 60 kg/m2	Bulk, injected	0,040	8 hours
Hemp	Flexible panels or rolls	0,040	7 hours
Glass wool	Rols	0,039	6 hours
