Reynaers Aluminium / Slim aluminium windows

SlimLine 38

A slim steel-look aluminium window system for renovation and contemporary architecture where narrow sightlines are essential.

KEY PARAMETERS

What matters at specification stage.

SlimLine 38 is chosen for its proportion, but it still has to work as a complete window.

System depth

107 mm

Visible width

from 60 mm

Frame Uf

up to 1.4 W/m²K

Element Uw

up to 0.74 W/m²K

Max. height

up to 3000 mm

Max. vent weight

up to 170 kg

Air permeability

class 4

Watertightness

9A

Wind resistance

C3

Sound insulation

up to 48 (-1; -3) dB

Its slender steel-like geometry suits refurbishment and restrained contemporary architecture. Sash size, glass build-up, thermal performance and hardware remain the same engineering constraints as with any other system.

PROFILE CROSS-SECTION

SlimLine 38 profile geometry in detail.

This image shows the system's profile geometry, chambers, thermal breaks and glazing zones. The final junction is selected for the opening scheme, glass build-up, dimensions and project loads.

ARCHITECTURAL CAPABILITY

Why we consider this system.

01

Steel-look architecture without bulky frames

02

Inward and outward opening variants

03

HI+ option for higher insulation

04

Suitable for complex geometry and renovation

SYSTEM CONTEXT

* Published SlimLine 38 values belong to specific configurations. Profile expression, glass and opening type all change the performance of the finished window.

With SlimLine 38, we set the architectural line first and then check its technical limits.

Our engineering approach ↗

BIFORIUM / PRACTICE

A system only works as a whole with glass, hardware and installation.

Installation position, support, insulation, sealing and drainage belong in the specification rather than being improvised on site.

Open engineering details ↗
Glazing

Glazing is selected from actual Uw, solar, acoustic and safety requirements; large vents are also checked for glass weight.

Hardware

Hardware limits the viable vent geometry just as much as the profile. Concealed hinges and automation need early coordination.

Installation detail

Installation position, support, insulation, sealing and drainage belong in the specification rather than being improvised on site.

FAQ / SPECIFICATION

Questions to close before specification.

Can the system be selected only from catalogue performance?

No. Published values help shortlist options, but the finished element still has to be checked for size, glazing, weight, hardware, loads and installation detail.

Does every opening need the same glazing build-up?

Not necessarily. A south-facing elevation, a bedroom near traffic, a large fixed pane and an entrance leaf can require different glazing within the same project.

When should the installation detail be coordinated?

Before the final order. Finished-floor level, insulation, waterproofing, structural support and drainage can change the frame, threshold or final manufacturing size.

HOW TO READ THE DATA

Six values that shape the result.

A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.

Ufthermal transmittance of the frame
Uw / Udthermal transmittance of the complete window or door
Rwsound reduction index in dB
RCburglary-resistance class
Air / Waterairtightness and driving-rain resistance
Windwind pressure and permitted deflection

START A PROJECT

We select the system around the architecture.

Send façade photos or opening drawings together with the profile expression you prefer. We will compare SlimLine 38 variants for both appearance and technical limits.
