Modern glass and aluminum curtain wall facade at dusk

Aluminum systems · Engineering since 2017

Light, framed
with precision.

Windows, doors, sliding systems and curtain wall engineered around the way daylight, heat and sound actually move through a building.

Why the system matters

Performance begins long before the glass.

Larger glazed areas, tighter energy targets and higher acoustic expectations are decided by the frame — its thermal break, gaskets, drainage and hardware — not by the glass alone. We engineer the whole assembly so the drawing survives contact with the site.

  • Energy Efficiency

    Polyamide breaks and warm-edge spacers.

  • Thermal Performance

    Uw values from 0.62 W/m²K.

  • Acoustics

    Asymmetric build-ups to 44 dB.

  • Security

    Multi-point locking as standard.

  • Automation

    Concealed motorization ready.

  • 0.00 W/m²K

Pull the mullion across the opening. On the left, an older single glazed unit: cold surface, muted light, audible street. On the right, a FensPro thermally broken system.

How we work

From first sketch to the last gasket.

A four-stage engagement that keeps the envelope decisions ahead of the construction programme.

  1. 01

    Design consultation

    Sightlines, opening logic and performance targets reviewed against the drawing set.

  2. 02

    System selection

    We match frame depth, hardware class and glazing build-up to the real loads.

  3. 03

    Technical package

    Sections, thermal calculations, CAD/BIM and shop drawing support.

  4. 04

    Supply & support

    Scheduled delivery, installer briefing and on-site troubleshooting.

Applications

Built for the way modern buildings perform.

From the field

What project teams say.

  • The sightlines survived value engineering because the system was chosen for the loads, not the price list. That is rarer than it should be.

    Architect, mid-rise residential

    Toronto, ON

  • We had shop drawings back inside a week with the thermal numbers attached. It kept the envelope package on programme.

    Project manager, mixed-use

    Ottawa, ON

  • Eight metre openings that still operate with one hand two winters later. The hardware spec was right.

Technical FAQ

Questions we get before drawings are issued.

Still unsure? Our engineers answer specification questions directly — no sales gate.

  • Ideally at design development. Frame depth, structural mullion spacing and thermal targets change the architecture — resolving them before permit drawings avoids redesign later.

  • In most cases yes. Send the specified section and performance schedule and our technical desk will map it to an equivalent FensPro platform, noting any deltas in sightline or hardware class.

  • Up to roughly 3.5 m × 3.2 m per panel with 600 kg running gear, subject to glass make-up, wind load and track detailing.

  • Yes. DWG sections, Revit families and indicative Uf/Uw calculations are available in the resource library or on request for a specific configuration.
