Metal Cladding Energy Retrofit for Efficient Buildings

t503-48

A metal cladding energy retrofit adds a new outer skin of metal panels over an existing façade, usually with insulation and an air gap, to reduce heat loss and gain. It also refreshes the building's look and protects the original structure from weather. Designed and fabricated to measure, it suits both residential and commercial buildings.

What a Metal Cladding Retrofit Involves

A retrofit wraps an existing building in a second layer, typically aluminum or stainless steel panels fixed to a sub-frame. Insulation is placed between the old wall and the new panels, and a ventilated air gap is usually left behind the cladding so moisture can escape.

Because the work happens outside the existing envelope, residents can often stay in their homes while it is done. The result is a cleaner, more uniform façade with better thermal performance than the original wall.

Why Architects Choose Metal for Energy Upgrades

Metal is durable, lightweight and dimensionally stable, which makes it well suited to retrofits where the existing structure cannot carry heavy loads. Panels can be cut and folded to precise sizes, allowing clean joints and crisp reveals.

Planning the Retrofit Step by Step

A successful project starts with a site survey. Our team measures the façade on site, notes existing openings, balconies and structural elements, and checks how the current wall is built. Photos and measurements help us prepare an accurate drawing before any material is ordered.

Next comes a written specification covering panel profile, fixing method, insulation type and finish. The client approves the drawing and specification, then production begins in our workshop.

Materials, Finishes and Detailing

Choosing the right panel material and finish affects both thermal performance and how the building ages. Aluminum is light and easy to shape, while stainless steel offers excellent corrosion resistance near the coast. Hot-dip galvanizing and powder coating are common protective finishes for steel elements.

Detailing around windows, corners and balconies is where many retrofits succeed or fail. Thoughtful flashing, sealed joints and proper ventilation openings keep the system performing over time.

Fabrication and Installation Process

All components are fabricated in our factory at 37 Rival Street, Tel Aviv, which lets us control cutting, forming and finishing precisely. Parts are then delivered to site and installed by our team according to the approved drawings.

Where railings, balcony guards or sun screens are part of the design, they are coordinated with the cladding so that dimensions, fixings and finishes match. Safety elements are checked against the relevant standard, with exact values confirmed by the engineer.

Working With Your Team and Approvals

Metal cladding retrofits usually involve the architect, a structural engineer, the building committee and sometimes local authorities. We provide drawings and technical details that fit into this process and can adjust them to address feedback from each party.

Early coordination avoids redesigns later. Sharing your energy targets, budget range and aesthetic goals at the start helps us propose the most suitable panel system for the building.

Frequently asked questions

Does metal cladding really improve energy efficiency?

Yes, when combined with suitable insulation and a ventilated air gap, it reduces heat transfer through the façade. The actual gain depends on the existing wall and the design chosen.

Can a retrofit be done without moving residents out?

In many cases the work is carried out from the outside, so residents can usually remain in their homes. Access and scheduling are agreed with the building committee beforehand.

Which metal is best for a coastal building?

Stainless steel and properly finished aluminum resist salt air well. Your architect or engineer can confirm the best choice for your exposure conditions.

How do I start a project with your team?

Send us photos of the building and a short description of your goals. We then arrange an on-site measurement and prepare a drawing and written specification for your approval.

Common mistakes to avoid

Many projects underestimate detailing around openings and balconies, which causes leaks and thermal bridges. Skipping the ventilated air gap or choosing a finish unsuited to the environment also shortens the system's life.

Our recommendation

Measure and survey the existing façade thoroughly before choosing a panel system, and agree the fixing and ventilation details with your engineer at the drawing stage. Early coordination saves time and prevents costly changes during installation.

Summary

A metal cladding energy retrofit can improve a building's insulation, durability and appearance when planned and detailed properly. Accurate surveys and careful coordination are the keys to a successful result.
