What it is
Aluminium windows
A deep, thermally broken window and door system for projects with high demands on the building envelope.
Role in the project
Genesis 90
Genesis 90 is designed mainly for external windows, with door variants from the same family.
What to consider
Purpose and limitations
The reference to the Passivhaus standard and the Uw value apply only to a configuration backed by appropriate evidence.
Clear recommendation
Why choose Genesis 90?
The premium Genesis choice for thermal insulationPremium
Choose Genesis 90 when the insulation of the building envelope, a low-energy standard and long-term efficiency take priority over the lowest initial cost.
Best for
- Low-energy projects and buildings designed to meet passive house requirements.
- Premium residential and commercial building envelopes with high thermal insulation requirements.
- Projects in which the profile, advanced glazing and installation are designed as a single thermally insulated assembly.
Main advantage
The deepest and best-insulated of these three systems: frame depth 90 mm, sash depth 99 mm, a wide thermal break, and standard, ‘i’ and ‘i+’ variants.
When not to choose it
Not needed when standard thermal calculations for the building show that Genesis 65 or 75 is enough and keeping the initial cost down matters more than extra thermal headroom.
Closest alternative
Genesis 75 is the alternative when you need very good insulation and a better overall balance of performance and cost, without moving up to the deepest system.
Price level
PremiumThe highest price level of these three Genesis systems; it is not automatically the best choice for every opening.

Key points about the system
A component designed for passive houses does not automatically make the whole window a passive-house window.
The permitted combination of height, weight, glass and hardware is confirmed for each sash individually. The classes shown come from the manufacturer’s data; whether they apply to the assembly offered is confirmed by a relevant test report.

Before the final specification
What is the Genesis 90 system?
A deep, thermally broken window and door system for projects with high demands on the building envelope.
What is the Genesis 90 system designed for?
Genesis 90 is designed mainly for external windows, with door variants from the same family.
What should you consider when choosing the Genesis 90 system?
The reference to the Passivhaus standard and the Uw value apply only to a configuration backed by appropriate evidence.
Is all the technical data the same for every version?
Sizes, glass, hardware, structural calculations, threshold and opening type are confirmed for each individual opening – only then can the system be tailored to your LUMORA project.
Why choose Genesis 90?
Choose Genesis 90 when the insulation of the building envelope, a low-energy standard and long-term efficiency take priority over the lowest initial cost. The deepest and best-insulated of these three systems: frame depth 90 mm, sash depth 99 mm, a wide thermal break, and standard, ‘i’ and ‘i+’ variants.
When is Genesis 90 not the first choice?
Not needed when standard thermal calculations for the building show that Genesis 65 or 75 is enough and keeping the initial cost down matters more than extra thermal headroom. Genesis 75 is the alternative when you need very good insulation and a better overall balance of performance and cost, without moving up to the deepest system.
