Energy-saving Exterior Hanging Board

What is Energy-Saving Exterior Hanging Board?

Energy-saving exterior hanging board is a thermal decorative panel installed by external hanging method. Its core feature is that installation does not require bonding the panel to the wall, but rather fixing it to the exterior of the building facade through a metal keel system.

This installation method creates an air layer between the panel and the wall, allowing moisture inside the wall to escape while preventing winter condensate from accumulating inside the insulation layer. It is suitable for ultra-low energy consumption building projects with high requirements for wall airtightness.

Core Advantages

1. Dry hanging installation: Fast installation speed, unaffected by low temperature, rain or snow. Winter construction does not require consideration of mortar freezing issues like wet systems.

2. No damage to original wall: Especially suitable for energy-saving renovation of existing buildings — adding energy-saving hanging boards to old buildings does not require removing the original exterior wall finish. Keels can be installed directly outside the wall and panels hung, with minimal impact on normal office work inside the building.

3. Flexible disassembly and assembly: Individual panels can be independently removed and replaced, making later maintenance, insulation layer inspection, and exterior wall pipeline renovation convenient.

Old Building Energy-Saving Renovation Construction Process

Standard process for applying energy-saving exterior hanging boards to existing buildings:

Step 1 — Wall Substrate Inspection: Inspect the flatness, strength and moisture content of the original wall. Local leveling with cement mortar is required if flatness deviation exceeds 10mm/m.

Step 2 — Keel Installation: Install galvanized steel keel framework on the outer side of the wall. Keel spacing is determined by panel dimensions and wind pressure calculation, generally 600mm.

Step 3 — Panel Installation: Install panels from top to bottom onto the keel, reserving 5 – 8mm expansion joints between panels.

Step 4 — Sealing Treatment: Insert PE foam strips into panel joints and apply weather-resistant sealant. Use special aluminum alloy internal and external corner pieces at corners.

Step 5 — Finishing Details: Use metal cover plates to trim around windows and at the top of parapet walls to ensure rainwater does not penetrate the inner wall layer.

After renovation, the building energy-saving rate can be improved by 40% – 60%, while achieving an overall facade renewal effect.

FAQ

Q1: What is the difference between energy-saving exterior hanging board and thermal insulation decorative board?

A1: The main difference is the installation method. Energy-saving exterior hanging boards are installed through a keel dry-hanging system, creating an air layer between the panel and the wall. Thermal insulation decorative boards are directly bonded to the wall. The hanging method is more suitable for old building renovation as it does not damage the original wall.

Q2: How much does the energy-saving rate improve after installation?

A2: The building energy-saving rate can be improved by 40% – 60%, depending on the original wall condition and the thickness of the insulation layer selected.

Q3: Does the air layer between the panel and the wall cause condensation?

A3: No. The air layer is ventilated and allows moisture to escape, preventing condensation inside the insulation layer. This is one of the key advantages of the dry-hanging system for building envelope design.
