The Problem with Aluminum Facades

Aluminum conducts heat 1000× better than wood. Even narrow profiles cause massive energy losses – good thing this can now be solved far more affordably with ALU-THERMIC than with a new facade.

On top of that: most facades become leaky after 20+ years. Our system is the fast, cost-effective solution for that too.

High energy costs

Uninsulated aluminum facades are the primary source of energy loss in commercial buildings.

💸

Expensive alternatives

Full facade replacement can cost twice as much – and shuts down operations for weeks.

Mold & drafts

Cold pressure near windows leads to condensation, mold, and poor indoor climate.

The EU Buildings Directive (EPBD 2024) – What commercial property owners need to know now

Since May 2024, the new EU Buildings Directive is in force. From 2030, binding minimum energy performance standards apply to non-residential buildings. Those who renovate today secure subsidies, avoid penalties and increase property value – with the ALU-THERMIC system for no more than half the cost of a new facade.

2024

EPBD 2024 entered into force. Transposition into national law required by May 2026.

2026

Transposition in Germany: the Building Modernisation Act (GModG), promulgated on 28 July 2026, transposes the EPBD and replaces the GEG.

2030

Non-residential buildings must meet Minimum Energy Performance Standards (MEPS): better than the worst 16% of 2020 stock.

2033

Tightening: MEPS for non-residential buildings rises – must be better than the worst 26% of 2020 stock.

2050

Goal: Climate-neutral building stock in the EU by 2050. Early renovation = competitive advantage and property value increase.

Facts that should make every building owner act

These figures prove why aluminum facades urgently need insulation – and why now is the right time.

160 W/mK
thermal conductivity of aluminum

Aluminum conducts heat at 160 W/mK – compared to stainless steel (15 W/mK) or wood (0.13 W/mK), an extreme thermal conductor.

75%
of building stock is inefficient

Three quarters of EU buildings are considered energy inefficient – the annual renovation rate is just 1%.

40%
of EU energy consumption

Buildings account for around 40% of energy consumption and 36% of greenhouse gas emissions in the EU.

20–30%
heat loss through exterior walls

The largest transmission heat loss in a building usually occurs through the exterior walls.

10–20%
higher heating costs from thermal bridges

Thermal bridges such as uninsulated aluminum profiles can increase heating costs by up to 10–20%.

1%
annual renovation rate in the EU

According to the EU Buildings Directive, the annual renovation rate must at least double by 2030.

How the ALU-THERMIC System Works

Our unique system insulates and seals with a single material in all 3 dimensions – no demolition, no business interruption.

01

Survey & Prefabrication

Precise on-site survey. Insulating profiles are individually prefabricated.

02

External & Internal Installation

Straightforward installation from outside, and rarely from inside. Interior operations continue without disruption.

03

Insulation & Sealing

PE foam used as specialty insulation and seal against heat, water, and wind.

04

Completion & Color

Powder coating in any RAL color. Your facade looks brand new – and performs like it too.

Thermal Proof: Before & After

Infrared images don't lie. Red and orange areas show massive heat loss through uninsulated aluminum profiles – wherever the profiles run.

After ALU-THERMIC insulation: profiles appear blue-cold. Heat transfer through the aluminum is significantly reduced.

Before – high heat radiation
After – significantly reduced
Innovation

Insulated Pressure Plate 2.5"

Our pressure plate draws on around 20 years of experience in facade insulation. The insulating material in the U-profile fulfills three functions at once.

Our sealing principle follows the movements of the aluminum construction and keeps the corners permanently tight.

Fixation of the glass panes

Insulation of the space between the panes and the glass edge

Reference Projects

Over 20 years of successfully completed projects – from office buildings to curtain wall facades.

★★★★★

“Replacing the windows outright was ruled out on cost grounds. The ALU-THERMIC system preserved the building's original appearance – with demonstrably improved insulation. Across two winter seasons, no further condensation was recorded.”

Dipl.-Ing. Peter Heider
Freelance Architect · Energy retrofit, office building in Heidelberg

★★★★★

“ALU-THERMIC carried out the façade work in accordance with the contract and to our complete satisfaction – with great commitment, expertise and proactive cooperation. Their handling of tenants during the construction period was likewise marked by considerable professionalism and courtesy.”

Frequently Asked Questions

Why choose ALU-THERMIC over a full facade replacement?
Because you get the thermal upgrade of your aluminum facade for no more than half the cost of a full replacement – without demolition and without interrupting building operations. The existing structure stays in place, the work is carried out almost entirely from the outside, and your building remains fully usable throughout. A single overlay profile provides both insulation and sealing. Independently tested: in 2016 the Canadian laboratory CAN-BEST (ISO 17025) measured around 90% less air leakage per ASTM E283 and no water penetration at 720 Pa per ASTM E331. The system received an award at the Toronto Building Show 2015.
Which building types and facade systems can be retrofitted with ALU-THERMIC?
Our system works with virtually all aluminum facades: curtain walls, post-and-beam constructions (mullion-transom systems), punched window facades, ribbon facades, and bay windows with aluminum-frame facades. Applications include office and administrative buildings, corporate headquarters, high-rises, schools, hospitals, hotels, parking structures, shopping centers, business parks, commercial properties, and industrial buildings.
Is the system suitable for mullion-transom (post-and-beam) constructions?
Yes, especially so. Mullion-transom constructions are particularly prone to thermal bridges due to long aluminum profiles. Our specialty foam seals in all 3 dimensions – without touching the existing glazing or interrupting operations.
Does the business need to close during renovation?
No. The work is carried out almost entirely from the outside; only rarely is a short, pre-arranged visit inside needed. Your operations continue throughout.
How long does a typical renovation take?
It depends on facade size. Profiles are prefabricated, so on-site installation is fast. We'll plan timelines individually with you.
How much energy can I save?
The U-value of the refurbished aluminum profiles ranges from 1.0 to 2.0 W/(m²K) depending on age – well below that of an unrenovated aluminum facade. Evidence: in 2010 the Passivhaus Institut in Darmstadt calculated that, on a frame made of aluminium profiles without a thermal break, the insulated overlay shell lowers the frame U-value from 6.4 to 1.7 W/(m²K) – around 73% less heat loss through the frame (based on EN ISO 10077-2, including the fixing screws).
What about asbestos in older facades?
Since the original facade is not demolished, the asbestos problem is completely avoided – a key advantage over full replacement.
Can I choose the color?
Yes. We offer powder coating in all RAL colors. Your facade gets a fresh, modern look.
