Question about home insulation from SIP panels from Eugene
Honestly, it is not clear why did you even want to insulate a house from SIP panels? As a rule, the thickness of the ceilings and walls of such houses is initially calculated in accordance with the applicable territorial and construction standards of the region in which construction is planned. It is such that additional insulation is not required.

Advantages of SIP Panel Houses
The fact is that SIP panels already contain a heater - solid polystyrene foam glued between OSB sheets (less commonly polyurethane foam). The thermal conductivity of this material is lower than that of mineral wool. Simply put - it perfectly retains heat, one and a half times better than mineral wool.
Additional advantages are:
- Oriented particle boards are vapor-tight, therefore, the insulation located between them is not threatened by moisture penetrating from inside the premises and reducing its heat-insulating properties. In addition, the PPP itself does not absorb moisture, unlike mineral wool.
- The minimum number of joints, which even with high-quality installation are additionally sealed with foam, eliminating heat leakage.
- The absence of installation defects during the assembly of the house, the elements of which are manufactured in the factory.
I can assume that the thickness of the panels you used does not meet the requirements for the level of thermal insulation in your region, so additional insulation was required. In this case, you can leave everything as it is, although the inner layer of Izospan could not be done.
Note. Izospan is always mounted with the smooth side to the insulation.
Well, do not forget that the heat in the house largely depends on a well-designed heating system and the quality of the installation of doors and double-glazed windows.
Finish
In your case, we apply one version of the exterior decoration - a hinged facade. It is mounted on a frame fixed to the walls through the insulation. You can choose any materials for facing - siding, lining, block house, plastic, facade tiles, etc.
It is important that there is an air gap between them and the mineral wool - the ventilation gap.
Polyfoam and mineral wool insulation have approximately the same coefficient of thermal conductivity, which will depend only on the density of the insulation. SIP panels are designed for the usual conditions of heat preservation, that is, 60 to 80 W of heat energy per hour will leave the house in the winter in a square meter. If the homeowner wants to reduce heat loss to the level of a passive house, then the foam can be attached to the walls using Ceresit ST 83, ST 84, and ST 85 mixtures. In addition, the insulation is fixed with self-tapping screws with large plastic caps. Then, the surface is plastered over the grid, primed and painted with facade paint.
