In summer, the sunshine room becomes a “beautiful waste”, with an outdoor temperature of 30+℃ and an indoor temperature of 60+℃.
The reasons for this situation can be summarized as follows:
1. There is no shading plan for the sunny roof
2. The material selection and matching of the early sunshine room were unreasonable
3. The top and facade windows do not form a good ventilation and heat dissipation path
4. The owner has a deviation in their understanding of the performance of the solar room materials and did not choose the appropriate roof insulation material
If it really comes down to one reason, it is that [early selection of materials is not awesome]
Today we will have a specific discussion on how to make a good insulation and insulation plan for the top material selection of sunny houses.
Where to start with insulation in a sunny room?
Most of the solar heat enters the room through invisible light (Far infrared) radiation heat transfer and secondary heat conduction, and 40% comes from the visible light area, bringing high temperature through direct sunlight.
To achieve good insulation effect, it is necessary to use both hands to block the heat brought by invisible and visible light from entering the room.
Phenolic insulation board is recommended for the top material of the solar roof insulation design.
Double sided insulation aluminum foil board top
Interior decoration layer: solid wood plug-in board/gypsum board/integrated suspended ceiling, used to decorate the indoor top surface. This layer is made during the woodworking stage and does not belong to the category of door and window sunlight rooms;
Insulation layer: double-sided 2mm thick aluminum foil board, sandwiched with 2-8cm thick phenolic foam insulation board, with thermal conductivity between 0.020-0.025w/m.k, which has the function of heat insulation and load bearing.
