The portable soundproof and thermal-insulation demonstration case — developed by LONROY — is a specialized tool designed for door and window sales representatives and home renovation companies to facilitate field-based client acquisition. Featuring a portable, pull-along design that can be operated by a single person, it is ideal for use in real estate model homes, mobile exhibitions in towns, and in-home consultations. It effectively overcomes the challenge of demonstrating large, bulky product samples off-site.

Equipped with a high-capacity built-in battery, the unit allows for sound insulation demonstrations without the need for a 220V mains power supply, making it perfect for locations in counties or suburban areas where electricity may not be readily available. For thermal insulation demonstrations, the unit can be connected to a standard power outlet.

It supports multiple audio sources — including direct input and Bluetooth — and features a real-time display screen for monitoring decibel levels and temperature differentials. Designed to accommodate a 450*600mm inward-opening sample window, the compact unit is easy to transport and store, making it an essential tool for sales professionals on the go. It is perfectly suited for use at real estate project sites, residential group-buying events, regional building-material roadshows, and in-home client visits by renovation firms.
