Every home presents a different set of challenges — from street noise and solar exposure to structural constraints and façade preservation.
These case studies show how window, glass door, shading, and fire-rated systems are applied in real residential environments. Each project reflects a specific need, a considered solution, and a measurable improvement in everyday comfort.
Rather than focusing on products alone, these examples show how systems perform when integrated into lived spaces.
With over 24 years of experience sourcing and installing systems in residential environments, Ola Janelas works with established European manufacturers such as Salamander and Aliplast. This includes experience across simple retrofits and upgrades, as well as full-scale renovations and new-build installations involving window and door systems, external roller shutters, and concealed shutter systems integrated into the building envelope.
The projects below reflect some of the most common situations homeowners face.
Apartments in built-up areas often require improved acoustic insulation while maintaining natural light and existing façade character.
Street-level homes benefit from solutions that combine thermal performance, noise reduction, and increased resistance to forced entry.
Homes with strong sun exposure require solutions that help manage heat gain while preserving bright interior spaces.
Shared residential buildings require solutions that support safe evacuation routes while maintaining visibility and usability.
External noise + façade preservation
High-performance acoustic window systems
Security + environmental stability
Reinforced glazing and acoustic control
Heat gain and glare
Aluminium systems with external shading
Fire compartmentation and evacuation
Fire-rated glazing systems
Each case study focuses on a real installation, showing how systems are selected and applied based on the conditions of the space.
Window and glass door replacement in a historic urban setting, balancing acoustic comfort with façade preservation.
Ground-floor installation focused on improving security, reducing noise, and stabilising indoor conditions.
New-build solution combining aluminium systems and external shading to manage heat and light.
Fire-rated glass door systems integrated into shared residential spaces to support safe and visible escape routes.
These projects are intended to help you understand how different solutions apply to real homes.
“Seeing real project examples made it easier to understand how different systems would work in our own home. It gave us the confidence to move forward knowing what to expect in terms of performance and installation.”
João Martins, Leiria, Portugal
