What is Protection for Large Openings?
Wide sliders, balconies, shopfronts, restaurants, hotel entrances and garages can create much greater system loads and more complex operational requirements than conventional windows.

What project teams need to know about Protection for Large Openings.
What project information should Apollo receive first?
Send the project location, building type, drawings or clear photographs, relevant dimensions and structural information, and any known wind, design-pressure, impact, flood, shelter, access or local-code requirements that apply to this system.
Can this system be specified from website information alone?
No. Site hazard, dimensions, loads, support and anchorage, exact product configuration, installation method, applicable technical evidence and local approvals can all change the final specification.
Does Apollo install this protection system?
Apollo is supply-only. Final engineering, fixings, installation, approvals and local code compliance remain with the appropriate manufacturer, approved specialist or client-side project team unless expressly included in the written scope.
Can Apollo review this system for international projects?
Yes, where the product and project can be supported. Destination hazard, climate, freight, documentation, local engineering, certification and installation responsibilities are reviewed before supply.

01Project guidance
Opening area changes total load.
As width and height increase, demands on shutter profiles, guide tracks, glass, frames, motors and anchors can increase substantially. A small-opening result should not be assumed to apply indefinitely as size grows.
02Project guidance
Accordion and roll-down systems solve different geometry.
Accordion shutters are strong where side stacking suits a wide horizontal span. Roll-down systems are strong where overhead housing, vertical deployment and motorisation fit the building.
03Project guidance
Impact systems can keep large openings transparent.
Suitable impact sliding doors or storefront systems can provide permanent protection where a tested or engineered configuration exists for the required size and project pressures.
04Project guidance
Garages and rolling doors need their own evidence pathway.
Do not assume the same impact standard or test scope used for windows automatically applies to exterior garage or rolling doors.

Performance follows the exact system and project.
Opening size, positive and negative design pressures, impact requirements, tracks or frames, anchors and structural substrate all affect final performance. Numerical wind, impact and certification information is matched to the applicable tested or engineered configuration for the project.
