What we do
Commercial Windows, Doors & Glazing
A building's envelope has to do a lot at once: let light in, keep weather out, stay secure, hold heat, and - increasingly - resist fire where the design requires it. MGN Group supplies and installs commercial aluminium glazing systems that meet those demands, from a single replacement door to a full curtain-walled façade. Where a screen or door forms part of the fire strategy, it is installed with the same rigour as our fire doors.

Trusted by 250+ Scottish Businesses - What Our Clients Say
Fire-rated windows and doors must be certified and correctly installed to perform as intended. Where a door set or glazing unit forms part of a building's fire strategy, the responsible person carries legal liability if it's non-compliant or incorrectly fitted.
Thermal Performance (Approved Document L)
Aluminium systems are thermally broken and glazed to meet the U-value and energy requirements for the building.
Security (Approved Document Q / PAS 24)
Entrance and ground-floor systems specified to meet security requirements where they apply.
Fire-Rated Glazing (Approved Document B / BS EN 1634)
Where a fire performance is required, glazed screens and doors are installed as tested systems to achieve the rated period.
UKCA / CE Marking
Systems supplied with the required conformity marking for construction products.
This summary is not legal advice - your building's fire strategy and Building Regulations approval set out the performance your envelope must achieve.
Quick answers
Commercial. MGN Group supplies and installs aluminium window, door, curtain walling and shopfront systems for commercial and public-sector buildings - offices, healthcare, education, retail and new-build developments - rather than domestic replacement work.
A non-loadbearing aluminium framing system that forms the outer face of a building, carrying glazing and infill panels and transferring wind loads back to the structure. It creates the large, uninterrupted glazed façades common on modern commercial buildings, and is designed for weather-tightness, thermal performance and movement.
Yes - commercial-grade aluminium systems, thermally broken and slim-framed, are what we supply and install. Aluminium gives the strength for large spans and heavy-traffic entrances, with the durability and low maintenance a commercial building needs.
Yes. Fire-resisting glazed screens and doors are installed as complete tested systems - glass, frame, beads and seals together, because the rating belongs to the assembly rather than the glass alone. As a passive fire protection specialist we also handle the perimeter sealing the rating depends on.
Both. We can supply and install a complete package from survey through to handover, or install client-supplied or fabricator-supplied systems where that suits the project and its procurement route.
