RC1 and RC2 Security Hardware: Where It’s Actually Available in the OKNOPLAST Line

RC1 and RC2 burglary-resistance hardware is confirmed and documented for PAVA and PIXEL tilt and turn windows and for HORIZON, OKNOPLAST’s uPVC lift and slide patio door – but not for every product in the US catalog. Entry doors, COMPACT, and the Aluview aluminum patio door family carry standard multi-point locking without a published RC1 or RC2 option in current OKNOPLAST US technical documentation, which makes RC-class hardware a product-specific specification decision rather than a line-wide standard feature.

What RC1 and RC2 Actually Mean Under EN 1627

EN 1627 is the European standard defining burglary resistance classes for doors, windows, and curtain walling, rating a structure’s ability to resist a defined attack method and duration rather than describing hardware in general terms. RC1 covers resistance to opportunistic attempts using physical force alone, such as kicking or shoulder-charging, without tools. RC2 covers resistance to attempts using simple tools – screwdrivers, pliers, wedges – for a defined test duration, representing a meaningfully higher resistance threshold than RC1.

Because EN 1627 is a European standard rather than a US-specific code, RC1 and RC2 hardware in OKNOPLAST’s catalog functions as a voluntary upgrade path above standard hardware rather than a code-mandated feature for any US jurisdiction; no US building code currently references EN 1627 as a compliance pathway.

RC1 and RC2 on PAVA and PIXEL Windows: WINKHAUS Hardware

PAVA and PIXEL tilt and turn windows use a WINKHAUS multi-point locking system documented with Standard, RC1, and RC2 hardware options available across nearly the full range of sash heights OKNOPLAST offers – confirmed as available (“yes/yes/yes”) for sash heights from 424 mm up to 1,815 mm, with RC1 and RC2 continuing to apply above that height as well. The hardware table also documents a mishandling device and sash lift becoming available at sash heights above 891 mm, and a balcony catch (win-click) option at specific taller sash-height ranges.

• PAVA/PIXEL → Hardware system → WINKHAUS multi-point locking
• PAVA/PIXEL → Security classifications documented → Standard, RC1, RC2
• PAVA/PIXEL → Sash height range with confirmed RC1/RC2 → 424 mm and above
• PAVA/PIXEL → Additional hardware → Mishandling device, sash lift (above 891 mm sash height)

Handle height and hardware configuration scale with sash height rather than staying fixed: a 424-644 mm sash uses a 184 mm handle height with no custom setting option, while a sash taller than 1,815 mm uses a 1,070 mm handle height with multiple lowering options depending on the exact height – meaning RC-class hardware selection and handle placement are specified together, not independently.

RC2 on HORIZON: The Only Patio Door With Confirmed Security Hardware Upgrade

HORIZON, OKNOPLAST’s steel-reinforced uPVC lift and slide patio door, documents an option to add hardware with increased security in RC2 class, confirmed both in HORIZON’s marketing materials and in a dedicated technical hardware diagram showing the specific RC2 components: an upper locking element, a 2 mm washer, and drilling protection rated for a 37.5 mm cylinder diameter. This is the only patio door in OKNOPLAST’s current US catalog with a documented RC2 option.

RC2 on HORIZON is an add-on rather than standard equipment – the base HST HORIZON hardware set operates without the RC2-specific components, which are called out separately in OKNOPLAST’s technical catalog as distinct parts added to the standard multi-point locking hardware. An architect specifying RC2 for a HORIZON opening should confirm it explicitly as a selected option rather than assume it ships by default.

RC-Class Availability Across Custom Window Shapes

RC-class hardware availability varies by shape within PAVA’s non-standard window catalog rather than applying uniformly. Trapezoidal windows document RU hardware in RC1, with RC2 specifically limited to structures with rectangular sashes. Arched windows document RU hardware in RC1 only, with no RC2 option listed. Round windows are documented with standard R and U hardware only, without an RC1 or RC2 designation in the round-window-specific specification.

This means a custom-shaped accent window and an adjacent standard rectangular tilt and turn window on the same elevation may not carry the same maximum security classification, even when both are built on the same PAVA platform – a detail worth confirming shape-by-shape rather than assuming parity with the rectangular product line.

Where RC-Class Hardware Isn’t Confirmed: Entry Doors, COMPACT, and Aluview

Three product lines in OKNOPLAST’s US catalog do not carry a published RC1 or RC2 option in current technical documentation. Entry doors, Basic and Premium, ship with a 3-point automatic lock and a cylinder lock or cylinder knob as standard equipment, without a documented RC-class upgrade path – notably different from the RC2-rated “Entrance doors 125” configuration that does exist in OKNOPLAST’s broader technical catalog but is explicitly restricted to Polish and German markets.

COMPACT, OKNOPLAST’s uPVC sliding patio door, uses Roto Patio Inowa hardware rather than the WINKHAUS system found on PAVA and PIXEL, and no RC-class option is documented for it. The Aluview aluminum patio door family – Standard, Premium, Sky+, and Fold – documents handle finishes and threshold configurations in detail but does not list an RC1 or RC2 security classification in current US technical materials. An architect requiring documented RC-class hardware on any of these three product lines should confirm current availability directly with OKNOPLAST rather than assume it based on parity with PAVA, PIXEL, or HORIZON.

Table 1 – RC1/RC2 Availability Across the OKNOPLAST US Line

Multi-Point Locking as the Security Baseline, With or Without RC Upgrade

Every OKNOPLAST tilt and turn window and patio door, regardless of RC-class availability, ships with multi-point locking as standard equipment – 3 to 5 compression points engaging simultaneously around the sash perimeter on windows, and a comparable multi-point system on patio doors, drawing the sash uniformly against the perimeter gasket when engaged. This is the security and air-infiltration baseline across the entire line, independent of whether a given product also offers a documented RC1 or RC2 upgrade.

For product lines without a documented RC-class option – entry doors, COMPACT, and Aluview – this multi-point baseline is the confirmed security specification to reference, rather than an assumed but undocumented RC rating.

Choosing Standard, RC1, or RC2 for a Project

For PAVA or PIXEL windows and HORIZON patio doors, RC2 is the appropriate specification for ground-floor openings, street-facing elevations, or any opening where documented forced-entry resistance beyond standard multi-point locking is a project requirement, since both product lines have a confirmed path to that classification. For custom-shaped windows, RC-class availability should be confirmed shape-by-shape before finalizing a security specification that assumes parity with rectangular units – trapezoidal and arched shapes carry at least RC1, while round windows currently document no RC-class option at all.

For entry doors, COMPACT, and the Aluview patio door family, standard multi-point locking is the confirmed baseline; a project requiring documented RC-class hardware on one of these three lines should raise that requirement directly with OKNOPLAST during specification rather than assuming it can be added as a standard catalog option.

Handle Height and RC Hardware: Specified Together, Not Independently

PAVA and PIXEL’s WINKHAUS hardware table ties handle height directly to sash height rather than treating the two as separate decisions: a 424-644 mm sash uses a 184 mm handle height with no custom setting option, a 645-890 mm sash allows a lowering option to 184 mm, and sashes above 1,815 mm use a 1,070 mm handle height with up to four lowering positions depending on exact height. RC1 and RC2 hardware remain available across this entire range, which means selecting a taller sash and a lower handle position doesn’t come at the cost of security classification.

This matters at the specification stage because handle height also affects accessibility and daily operability – a lower handle position on a tall sash is often chosen for reach rather than security, and OKNOPLAST’s documentation confirms that choice doesn’t force a tradeoff against RC1 or RC2 availability within the documented sash height range.

Balcony Catch (Win-Click): A Secondary Lock for Tilt and Turn Balcony Configurations

A balcony catch, cataloged as win-click, is available as an additional locking option on PIXEL sashes within specific height ranges – confirmed available on sashes from 1,236 mm up to 1,815 mm tall, but only from a sash height of roughly 1,696 mm when a central handle is used, and not available at all in combination with a central handle above certain configurations. This is a secondary catch rather than a replacement for RC-class hardware, adding an additional physical lock point relevant to balcony and Juliet-door configurations built on the window platform.

Because win-click availability depends on both sash height and handle position simultaneously, it’s a detail worth confirming during the same specification pass as RC-class hardware rather than assuming it’s available anywhere a balcony configuration is used.

Steel Reinforcement as a Passive Security Layer, Independent of RC Class

Galvanized or stainless steel inserts, factory-pressed into the load-bearing chambers of PAVA and HORIZON’s frame, sash, and mullion profiles, resist prying and frame-spreading attacks independently of whichever hardware classification – Standard, RC1, or RC2 – is specified on top of them. This is a structural property of the frame itself rather than a hardware feature, which means it applies even on a PAVA window or HORIZON door specified with Standard hardware rather than an RC upgrade.

This distinction is worth making explicit because RC1 and RC2 ratings describe hardware resistance to specific attack methods under EN 1627, not the overall structural resistance of the frame – a steel-reinforced frame with Standard hardware and a steel-reinforced frame with RC2 hardware differ in how the lock resists forced entry, not in whether the surrounding frame itself resists being pried apart.

Glazing Security Class: Confirmed for PL/DE Only, Not Yet for the US Line

OKNOPLAST’s broader technical catalog documents a P4 security glazing classification under PN-EN 356 for laminated glass, but that specification appears in the same market-restricted entrance-door documentation already excluded from this guide – the RC2-rated “Entrance doors 125” configuration limited to Polish and German markets. No P-class or other laminated security glazing rating is currently confirmed in OKNOPLAST’s US technical documentation for PAVA, PIXEL, HORIZON, or any other US-catalog product.

Hardware security (RC1/RC2) and glazing security (laminated glass resisting penetration even if the frame is breached) are two independent specification layers worth keeping separate. A project requiring documented glazing-level security in addition to RC-class hardware should raise that requirement with OKNOPLAST directly, since current US documentation addresses hardware classification only.

Entry Door Cylinder Security: What’s Documented and What Isn’t

OKNOPLAST’s US entry doors, Basic and Premium, ship with a cylinder lock or cylinder knob supplied with 3 keys standard, with a key-alike option available for projects specifying multiple entry points under one keying schedule. Current US documentation does not specify a cylinder pick- or drill-resistance rating – such as the European EN 1303 cylinder classification system – for these entry door cylinders, distinct from the RC1/RC2 hardware classification that does apply to PAVA and PIXEL windows.

An architect specifying an entry door for a project with a documented cylinder security requirement should confirm the specific cylinder hardware and any resistance rating with OKNOPLAST before finalizing the specification, since the 3-key-standard detail describes keying convenience rather than a pick- or drill-resistance classification.

RC-Class Hardware in Insurance and Commercial Specification Context

In European markets, RC2-rated hardware is sometimes referenced in insurance underwriting or commercial building specifications as a documented burglary-resistance benchmark, since EN 1627 provides a standardized, third-party-testable classification. In the US, no equivalent code or insurance framework currently references EN 1627 directly, which means RC2 hardware on a PAVA, PIXEL, or HORIZON specification functions as a documented performance upgrade an architect or owner can point to, rather than a rating tied to a specific US insurance discount or code credit.

For a commercial or multifamily project where a specification document benefits from a third-party-testable security classification rather than a general manufacturer claim, RC2 hardware on PAVA, PIXEL, or HORIZON is the closest match currently available in OKNOPLAST’s US catalog to that kind of documented, standard-referenced performance claim.
