Quote: timber-aluminium windows
E.g.: Warm wood interior, maintenance-free aluminium exterior, on the renovation of an old house.
Describe the desired interior and façade appearance, then request the model’s exact construction. Provide openings, fitting constraints and performance needs. Choose an identified system rather than a generic premium-range promise.
Identify mixed construction
Internorm describes interior timber and protective exterior aluminium cladding. This proves neither maintenance-free operation nor performance across all mixed systems. Request the proposed product’s section and reference.
Select both finishes
Request timber species or interior construction, finish and samples. Specify exterior cladding colour and appearance. Check visible profiles, junctions and alignment with other openings. Record selected references before manufacture.
Check product and site work
Request feasible dimensions, opening leaves, glazing, hardware and model data. Confirm fitting, junctions and shutter/ventilation compatibility. Keep requirements and services equivalent when comparing PVC, aluminium or timber alternatives.
Plan care and intervention
Request instructions for interior timber, cladding, seals and hardware plus access to replaceable parts. Clarify warranties. Have damp or damage assessed; cladding does not mean timber can never be damaged.

Frequently asked questions
Is timber-aluminium maintenance-free?
Request instructions for every system part. Cladding does not eliminate surface and mechanism care.
Can interior timber be damaged?
Do not assume it cannot. Have observed damp or damage assessed.
Will resale compensate the premium?
No documented uplift is established here. Decide from the offer and your use.
What manufacturing time applies?
The time confirmed for ordered references and manufacturer scheduling, not a universal material duration.
