The client wants the wall to open onto the outdoors. They also want insects out. Traditional screen doors — a full aluminum-frame screen swinging on hinges — don’t fit the design vocabulary of a modernist glass wall. They read as an afterthought. Retractable and pleated screen systems are the specification answer. They preserve the sightlines of the closed glass wall, deploy when the wall is open, and disappear into a pocket when not in use. They sit alongside the rest of the custom architectural glazing and unique configurations [/guide/custom-architectural-glazing-and-unique-configurations/ →](/guide/custom-architectural-glazing-and-unique-configurations/) that let a specialty opening resolve cleanly. Alta Vetro’s specialty-systems line [/specialty-systems/ →](/specialty-systems/) includes screen configurations engineered for large openings — for the sliding walls [/sliding-glass-doors/ →](/sliding-glass-doors/) and bi-fold walls [/bi-fold-doors/ →](/bi-fold-doors/) the design consultation typically pairs them with. ## How Retractable Screens Work A retractable screen has three components: **Screen fabric on a spring-loaded roller.** The screen is a fine mesh — usually fiberglass or polyester — wound around a roller housed in a discreet cassette. When deployed, the screen unrolls across the opening. When retracted, spring tension pulls it back into the cassette. **Housing at one side of the opening.** The roller cassette is mounted at one jamb of the opening — sometimes integrated into the wall assembly, sometimes as a discreet exterior housing. When retracted, only the housing is visible; the screen is inside. **Guide tracks at the top and bottom.** Thin tracks at the head and sill guide the screen when it’s deployed. The tracks are minimized so they don’t interrupt the sightline when the screen is not deployed. The mechanism is simple, quiet, and reliable. A well-installed retractable screen on a 20-foot sliding-glass opening deploys with one hand and retracts smoothly for years. ![Detail of a pleated screen mesh and slim housing](/images/content/detail-of-pleated-screen-mesh-and-slim-housing-pre.webp) ## How Pleated Screens Work Pleated screens use a different mechanism. The screen fabric is folded into vertical pleats (an accordion pattern), so that when deployed, the pleats spread out across the opening, and when retracted, they compress into a compact stack at one side. Pleated screens work well for very wide openings because the pleated fabric handles wide spans without sagging. They also deploy more visibly than retractable roller screens — when partially deployed, the pleats are visible across the deployed portion. When fully retracted, they compress to a small stack similar to a folded bi-fold panel. The choice between retractable and pleated depends on the opening width and the design preference for the deployment mechanism. ## Integration With Bi-Fold Openings On a bi-fold wall, the screen typically integrates into a pocket at the fold-side jamb — the same side where the folded panel stack sits when the bi-fold is open. When the bi-fold folds open, the screen can be deployed across the (now open) opening to admit air and light while keeping insects out. The pocket integration keeps the screen invisible when not deployed. From the interior, the bi-fold looks like a bi-fold — no visible screen apparatus. The bi-fold hub [/bi-fold-doors/ →](/bi-fold-doors/) covers the bi-fold specification context. ## Integration With Sliding Openings On a sliding-glass wall, the screen integrates through a dedicated pocket at one wall — usually at the opposite side of the opening from where the sliding panels stack. When the sliding wall is open, the screen deploys across the (open) opening independently of the sliding panels. On multi-panel sliding configurations, the screen coverage typically spans the whole opening even when only a portion of the sliding wall is open. The deployment is coordinated with the daily-use pattern. ## Screen Fabric Options Standard screen mesh options include: **Fiberglass mesh** — the standard specification, insect-tight and durable **Polyester mesh** — used for larger spans where fiberglass may sag **Solar-control mesh** — reduces solar heat gain on west-facing openings (used selectively) Mesh color options include black (most common — reduces visual interference), charcoal, and specialty tones matched to the frame finish. ## When Screens Are the Right Specification For most Colorado mountain-home applications, screens are optional — the mountain climate has limited insect pressure through most of the year. On applications where evening insect exposure is a real concern — lower-elevation Front Range projects, applications near water features, projects with specific insect issues at the site — the screen specification is worth including. The design consultation walks through whether screens are required for the specific project and, if so, which mechanism (retractable or pleated) fits the opening and the design vocabulary. The specialty systems hub [/specialty-systems/ →](/specialty-systems/) covers the full specialty-systems line, and the architect and builder specification resource guide [/guide/architect-and-builder-specification-resource-guide/ →](/guide/architect-and-builder-specification-resource-guide/) covers how the screen specification integrates into the broader specification package. FAQ ## Related Questions ### Do screens block the view? Retractable and pleated screens minimize visual impact when deployed, and retract fully into a pocket or housing when not in use. When not deployed, they are essentially invisible. ### Can screens fit large openings? Yes. Retractable and pleated screen systems are engineered for the large sliding and bi-fold openings the specialty-systems line typically serves — spans up to 24 feet or more with appropriate configuration. ### Do they integrate with the doors? Yes. Screens integrate with the door system through pocket integration at the fold-side jamb (for bi-fold) or through a dedicated pocket at the wall assembly (for sliding). The design consultation coordinates the integration during specification.
