Aluminium windows FAQ
What is the difference between the S64RP and S88RP series?
The S64RP is the standard series with very good performance. The S88RP is the premium range with maximum insulation (Uw around 1.0 W/m²K), ideal for cold areas such as Sierra Nevada.
The S74RP sits in between. We advise you on the right series for your climate zone and orientation.
Does thermal break aluminium insulate as well as PVC?
With thermal break, aluminium achieves performance very close to PVC, with the advantage of greater structural strength and slimmer profiles.
What determines the price of STRUGAL aluminium windows?
Every window is a made-to-measure project, so we do not publish indicative prices. The cost depends on the series, size, opening type, glazing, hardware and finish.
Request a free, no-obligation online quote with your measurements and photos; if a technical home visit is needed, it has a cost, which we tell you before booking it.
Can I buy them without fitting?
Yes. STRUGAL aluminium windows can be bought with or without fitting.
If you already have an installer, see our page on STRUGAL aluminium windows, supply only.
What colours are available?
The full RAL chart, silver, bronze and black anodised, wood effects and two-tone finishes (different colour inside and out).
How long do aluminium windows last?
With minimal care, STRUGAL aluminium windows have a service life of decades. They only need a clean with water and neutral soap and occasional lubrication of the hardware.
