Window Installation
Precision fitting. Airtight detailing. Energy-performance driven installation.
We carry out full window replacement and installation across Luxembourg for residential properties,
including PVC, aluminium, and timber systems with double and triple glazing configurations.
Every installation is treated as a building-envelope upgrade: thermal performance, airtightness, and
junction detailing are addressed as a single system rather than isolated components.

CORE ISSUES
Windows are one of the most critical points of energy loss in a building
In many homes, outdated window systems are responsible for a significant portion of heat loss, air
leakage, and acoustic inefficiency.
Typical issues encountered:
• Thermal inefficiency: outdated glazing systems leading to continuous energy loss
• Air leakage: poor frame sealing causing draughts and unstable indoor climate
• Condensation and mould formation: thermal bridging around frames and insufficient
insulation
• Noise infiltration: limited acoustic performance in older single or poorly sealed units
• Security limitations: outdated locking systems and weakened frame structures
Window replacement is not a cosmetic upgrade — it is a performance correction of the building envelope.
