SARENTA · ENVELOPE

Membrane vs hard-wall enclosure for clear-span structures.

The frame can remain similar while the building experience changes completely with the envelope.

SHORT ANSWER

Choose the envelope from occupancy, comfort and lifecycle—not appearance alone.

Use membrane where lightweight fast enclosure is valuable, hard-wall or insulated panels where durability and environmental control dominate, glazing where transparency is needed, or a mixed envelope where different elevations have different jobs.

KEY PROJECT POINTS

What should drive the decision.

These are project inputs, not substitute engineering or automatic product approvals.

01

Membrane is lightweight and fast but has different acoustic/thermal behaviour.

02

Hard wall/insulated panel adds mass and environmental control.

03

Glazing adds daylight but raises solar/thermal and structural considerations.

04

Fire evidence must match the exact membrane/panel material.

05

Envelope weight changes structural demand.

06

Replacement and maintenance strategies differ.

COMPARISON

Use-case fit before product preference.

The table is deliberately directional. Exact configurations still require project and evidence review.

PathwayBest fitWatch closely
PVC membraneLightweight fast enclosure and selected event/sport/project structures.Fire evidence, insulation/acoustics, puncture/repair and lifecycle replacement.
Hard wall / insulated panelMore permanent controlled environments.Added weight, interfaces, fire/thermal specification and construction complexity.
Glazed / mixed envelopeHospitality, entrances and architectural elevations needing transparency.Heat gain, wind loads, framing, safety glass and seals.
01

Start with internal conditions

Occupancy, heating/cooling, humidity, acoustics and daylight should drive envelope choice.

02

Check material evidence

Fire, thermal and material claims should be tied to the exact supplied membrane, panel or glazing build-up.

03

Coordinate structure and envelope

Cladding weight, openings and wind pressure affect the frame and connection design.

04

Plan replacement

Membranes, seals and selected panels may have different replacement cycles; access should be considered in the lifecycle plan.

EVIDENCE BOUNDARY

Envelope evidence must identify the exact material build-up.

Avoid applying generic membrane or panel certificates to different products. Fire, thermal, acoustic and material evidence should match the selected envelope.

FAQ

Questions project teams usually need answered.

Is membrane suitable for permanent buildings?

It can be for suitable projects, but design life, comfort, fire, acoustics and local requirements must be reviewed.

Are all SARENTA membranes the same weight?

No. Published membrane options span a range; the exact product is project-specific.

Can hard walls be combined with a membrane roof?

Mixed-envelope configurations can be considered where the selected structure supports them.
