Building envelope from a single source
Our services
As specialists in the entire building envelope, we do not view facades as individual components, but as an integrated system — technical function, structural safety and architectural excellence all in one.

Overview
Our services at a glance
Comprehensive facade construction — from the initial concept through to maintenance over the course of decades.
01
Holistic facade construction
We combine technical functionality, structural safety and architectural excellence into a seamless solution – precisely planned, designed and executed.
02
Specialised and project-specific solutions
No two projects are alike. We develop bespoke designs, tailored to the specific requirements of each project in terms of design, structural engineering and choice of materials. Where standard solutions reach their limits, that is where our area of expertise begins.
03
Project Support & Engineering
We provide comprehensive support for every project – from the initial contact through to design, manufacture, installation and final acceptance. Our engineering teams combine in-depth technical knowledge with experience gained from challenging construction projects.
04
Manufacturing expertise
Our manufacturing process combines state-of-the-art technology with precision craftsmanship. We produce components that are made to exact specifications and tailored to each specific project – prefabrication and quality control ensure smooth installation and a long service life.
05
Logistics & Assembly
Every component in the right place at the right time: with efficient logistics and experienced installation teams, we install facades precisely, safely and on schedule – regardless of project size or location.
06
Maintenance & servicing
To ensure that a facade remains functional in the long term and retains its appearance, we carry out maintenance and servicing. We inspect, optimise and repair before problems arise – ensuring lasting quality for decades to come.
07
Consultancy & Partnership
We see ourselves as a partner to architects and planners. Right from the early stages of a project, we work together to develop solutions and offer advice on materials, technical details and the choice of systems.
08
Tradition & experience
We have been synonymous with quality in facade construction since 1946. We combine this experience with modern engineering – tradition forms the foundation of our expertise today, not a thing of the past.
09
Specialised construction technologies
We specialise in VHF systems, metal and steel facades, glass facades, textile building envelopes, sun protection and bespoke structures – for maximum flexibility and creative freedom.
Areas of expertise
Twelve areas, one commitment
Carefully categorised by trade — each brand links to relevant showcase projects.
Windows, Doors & Sliding Systems
Aluminium windows and doors, sliding systems, as well as wood-aluminium and PVC structures (sourced externally) – thermally insulated, burglar-resistant and made to measure. From individual components to complete window fronts.
Mullion-transom insulated facades
Highly thermally insulated warm facades in an aluminium mullion-transom system, as well as steel (standard and laser-welded) and timber cladding systems – transparent building envelopes for large glazed areas.
Prefabricated & SG facades
Prefabricated modular facades for rapid installation, regardless of weather conditions, as well as structural glazing (SG) facades with frameless, full-surface glass panels – prefabricated to the highest standards of precision in the factory.
VHF – Metal
VHF systems with metal cladding and sheet metal facades – rear-ventilated, energy-efficient and durable. The substructure, insulation and cladding are all supplied by a single source.
VHF – Natural Stone & Ceramics
Ventilated curtain walls clad in natural stone and ceramic – high-quality, mineral-based surfaces offering excellent colour and dimensional stability for prestigious building envelopes.
VHF – Fibre-cement & glass-fibre-reinforced concrete
Large-format fibre-cement panels and glass-fibre-reinforced concrete (GFRC) for creatively flexible, rear-ventilated facades – lightweight, strong and available in almost any texture and colour.
Green facades
Green, rear-ventilated facade systems that blend architecture and nature – for a better microclimate, sound insulation and a vibrant appearance that matures over the years.
Photovoltaic facades (glass + PV)
Building-integrated photovoltaics in the form of a glass PV facade – the building envelope generates electricity whilst remaining a high-quality architectural feature. Energy generation and design combined in a single component.
Sheet metal fabrications & steel structures
Sheet metal and steel structures to complement our own range of facade solutions: parapets, flashing and shaped sheets, special profiles and load-bearing steel structures – precision-manufactured and installed.
Sun & Weather Protection + Automatic
Facade-integrated sun protection and automated systems: external blinds, screens and control systems – for shading, comfort and energy efficiency, seamlessly integrated into the building envelope.
Fire Safety & Security
Certified fire protection elements and windows, as well as safety-critical structures – tested for safety, discreetly integrated into the facade and documented in accordance with standards.
Additional trades: Roofing & Gates
To complement our own product range, we coordinate services from trusted subcontractors: roofing work, as well as doors and gates – ensuring that the building envelope is provided seamlessly from a single source.
