These heat preservation boards are generally flat, surface is smooth, easy to install. In construction, it can be fixed on the wall by pasting, anchoring etc., to form a thermal insulation layer. Heat preservation board can reduce wall heat transfer, prevent indoor heat loss in winter, block outdoor heat in summer, so as to achieve good thermal insulation effect.

[0003] Existing wall body heat preservation board is mostly installed by relying on smearing adhesive, and the quality of adhesive is uneven.

When the wall expands due to temperature change, the building subsides slightly, the four corners are prone to appear gap first.
