Description

A kind of light thermal-insulating door

The utility model relates to the door in the dwelling house.

Usually, the door that uses in the dwelling house, though wherein hollow core flush door is in light weight, easy deformation, heat insulation effect is bad, and hollow core flush door consumption timber is many and self is heavy, leaves the space between door and the doorframe, especially air-conditioned room, do not have insulation effect, the cost height, it is low to manufacture efficient.

The purpose of this utility model just provide a kind of in light weight, cost is low, good heat insulating is manufactured light thermal-insulating door easily and efficiently.

The technical solution of the utility model is a kind of light thermal-insulating door, comprise door wainscot and door outer panels, the door of inside and outside panel, be provided with framework, it is characterized in that door wainscot and door outer panels interlock cooperates shaping, be provided with adiabator layer between the two panels, be provided with outstanding tooth limit in door wainscot four sides.

Described adiabator layer is the polyurethane foam material insulation layer.

Described door panel is thin rolled steel plate.

The utility model cooperates shaping owing to adopt inside and outside panel to interlock, the thickness of rolled steel plate can be very thin, be provided with framework and polyurethane foam material insulation layer between the interior outer panels, make door not yielding, and, reduced cost from heavy and light, rolled steel plate is by drawing, improved production efficiency, wainscot four sides are provided with buck teeth limit, good seal performance.
