Heck Outdoor Acrylic vs Standard Indoor Curtain (Liz Linen): Which One Belongs Where?

Picture two buyers. One is staring at a three-season porch with a wraparound roof, west-facing, that gets hammered by afternoon sun from June to September. The other is a renter in a covered second-floor living room, north light, climate-controlled, who wants something softer than the white loops the previous tenant left behind.

Same question on the surface (“what curtain do I order from Two Pages?”), two completely different answers. The first one needs the Heck Solid Acrylic Outdoor collection. The second one needs a standard indoor curtain, and at Two Pages the standard-indoor benchmark is the Liz Linen Drape Pleated. Here’s why these two products live on opposite sides of a wall, and what happens when you try to swap them.

Quick Verdict by Use Environment

Let me start with the number that matters: 100% acrylic outdoor-grade on one side, 10% linen / 90% polyester OEKO-TEX on the other. That single composition gap drives every other answer in this article (UV behavior, drape, header logic, pricing, lead time).

Throughout this comparison, “standard indoor curtain” means Liz Linen Drape Pleated. It is the most-ordered Two Pages indoor SKU, the one that anchors the catalog at from $59.99/panel base, and the one that buyers most often confuse with an outdoor-capable option because it looks deceptively rugged at 350 gsm.

From here on the article walks dimension by dimension: material, header, lining, color and UV, pricing and service. Each section treats Heck and Liz side by side rather than producing two parallel monologues. By the end you’ll have a binary call, not a maybe.

Material & Weight

This is the section that ends most of the indoor-curtain-on-the-patio dreams. Acrylic and linen-polyester are engineered for different physics. The Heck body sits in the outdoor textile family alongside marine canvas and pergola shade fabrics. The Liz body sits in the indoor drapery family alongside cotton blends and pure linens, OEKO-TEX certified for chemical safety, not for weather (see the OEKO-TEX Standard 100 certified framework for what the cert actually covers). For the broader category logic on acrylic, bamboo and patio shade fabrics that all sit outside the indoor blend universe, our outdoor window treatments hub frames the full landscape one level up from this VS.

Translation: Heck is built to resist what’s outside (sun, water, mold, wind, fire). Liz is built to perform inside (drape softness, color saturation, header versatility, lining ladder). Both engineering choices are correct for their context. Neither is “better” in absolute terms.

Real talk on the weight gap. 260 gsm outdoor sounds lighter than 350 gsm indoor, and it is, but the gsm number does not translate directly between fiber families. Acrylic at 260 gsm holds outdoor drape under a 15 mph crosswind better than polyester at 350 gsm would, because the acrylic body is denser per fiber and the surface tension resists puffing. Liz at 350 gsm, hung indoors with no wind to fight, falls with a structured indoor weight that no outdoor acrylic can match for that “tailored library” look.

Two takeaways from the table. First, the headers and linings count alone tells you these are different product families: 1 vs 9, and unlined fixed vs 6-tier ladder. Second, the lead time gap (3 to 5 days vs 10 to 12 days) reflects the ready-made vs custom split, which we’ll come back to in the pricing section.

Header & Mounting

Here’s where the two products almost feel like they belong to different shops. Heck ships with one header, fixed. Liz lets you pick from nine at configuration. Both choices make sense once you know what each panel is being asked to do.

Outdoor mounting has constraints Liz never has to think about. A pergola beam is rarely level. A patio rod sits 18 to 24 inches from a stucco wall and catches every gust. Tension wire installs across two posts that move 1 to 2 mm in opposite directions all season. The 4-in-1 Soft Top is engineered to behave on all four of these scenarios without buyer decision fatigue. Pick the size, pick the color, hang it.

Indoor mounting on the Liz side is the opposite story. The room is square, the ceiling is level, the rod is fixed, and the buyer wants to control fullness, pleat shape and how the panel falls when drawn shut. Nine headers cover the range from casual Tab Top on a kitchen casement to Triple Pleat formal on a dining room window. Memory training (a Two Pages service that hand-trains the pleats to fold cleanly after delivery) is included with most pleated headers and changes how the panel reads after the first month of use.

Lining & Light Control

This is the section where buyers most often try to “upgrade” Liz into an outdoor curtain by adding a Blackout lining. That move does not work, and the lining ladder explains why.

Heck has no lining configurator. The acrylic body itself shades 80 to 92% of incoming light depending on color (deeper Mocha and Dark Navy push toward 92%, lighter Coconut and Natural sit closer to 80%). Adding a lining outdoors would trap humidity between two layers and accelerate mildew, which is exactly what the engineering tries to prevent. So Heck stays unlined, period.

Liz’s six-tier ladder is the reason buyers shopping for a bedroom or media room land here. From Unlined at ~55 to 60% shading (soft linen filter, daytime privacy partial) up to Blackout Thermal at 100%, you can tune the panel to the exact light job. No outdoor product, Heck included, can match that indoor precision.

If full blackout is the priority and the panel is staying inside, our Atlanta Room Divider blackout review sits next door in the same blackout decision tree (Atlanta is a different SKU built around a denser blackout body).

Color & UV Behavior

Heck offers 21 colors, Liz offers 38. On surface, the indoor catalog wins on variety. Dig one layer in, and the colorways are engineered for different jobs.

Heck’s palette is curated for outdoor coexistence: warm neutrals (Natural, Taupe, Tan, Mocha, Khaki, Coconut) that blend with cedar, teak, painted shiplap and stucco. Deep saturations like Dark Navy and Black are included because solution-dyed acrylic holds those depths under sun where surface-dyed indoor blends would chalk and fade within one season. For why 98% UV block actually matters here, the EPA UV Index scale gives the public reference: most of the US hits UV index 8+ on summer afternoons, and an untreated polyester or linen blend left in that load loses 20 to 40% of its dye saturation per season.

Liz’s 38 indoor colorways trade some weather durability for nuance under interior light. Snow White, Sand Beige, Tapioca, Oak Dim Gray, Grey Beige, Carbon Grey: each reads differently under 2700K warm LED, 3000K kitchen ambient and 5000K north-window daylight. The indoor palette is built to be lived with for 5 to 8 years inside, not weathered outside for one.

Pricing & Service

Heck is ready-made: six standard sizes, fixed pricing, 3 to 5 day ship. Liz is made-to-order custom: configurator pricing, 10 to 12 day lead. Two different service models for two different jobs.

Reading the cards side by side. A typical pergola opening (two 52″ wide panels for a 96″ wide bay, both at 96″ drop) lands at $218 total in Heck, ready to ship in a week. A typical living room opening (two 50″ wide Liz panels at 96″ drop with Cotton lining) configures at roughly $590 total in Liz, ready in 10 to 12 days. The Heck per-panel base is higher but the configuration scope is narrower, so the total often lands lower for outdoor jobs.

Both products run on the same promo code today. Code JULY takes 20% off sitewide, and Two Pages offers free shipping over $300 on either side of the catalog. A four-panel Heck order or a single Liz custom panel with lining both clear the shipping threshold easily. Made-to-order Liz panels are final sale once the configurator submits, which is the standard custom-curtain industry rule.

FAQ

Can I use a standard indoor curtain like Liz Linen on my covered patio?

Not for more than a couple of weeks. Liz Linen is a 10% linen / 90% polyester blend engineered for climate-controlled interiors. Polyester is not naturally outdoor-rated: it absorbs humidity, the linen fibers wick moisture, and mildew finds a foothold within one season on a covered patio that sees morning dew and afternoon rain. The OEKO-TEX certification covers chemical safety, not weather resistance. If the panel is going outside, even under a roof, Heck’s 100% acrylic body is the engineered answer.

Is Heck Outdoor Acrylic really waterproof or just water-resistant?

Water-resistant is the accurate word. The Heck acrylic body is hydrophobic: rain beads up and runs off rather than soaking in, and the fiber resists mildew, rot and fading. It is not waterproof in the rubber-membrane sense, so a hard sideways rain will still get the back side damp, but the panel dries fast and the dye does not bleed. For pergolas, porches, gazebos and poolside cabanas, the engineering is sized correctly. For full saltwater submersion or hurricane exposure, no curtain is the right product.

Why is Heck $40 more per panel than Liz at base price if it’s only 260 gsm vs 350 gsm?

Material cost flips the gsm logic. Outdoor-grade solution-dyed acrylic is more expensive per square meter than a 10/90 linen-polyester blend, because the pigment is locked inside the fiber during extrusion rather than surface-dyed after weaving. Add the UV stabilizers, the mildew treatment and the fire-retardant finish, and the per-panel cost rises. Heck also ships ready-made in 6 sizes (no configurator overhead, no custom cutting), which compresses the lead time but does not lower the fabric cost. The $40 gap funds the engineering, not the weight.

Can I get Heck in custom sizes if the 100″ × 108″ max is too small?

No. Heck is a ready-made collection: 52″ or 100″ wide, 4 drops (84 / 96 / 102 / 108). The custom configurator that powers Liz, Isabella and the rest of the indoor catalog does not apply to outdoor acrylic. If your opening exceeds 100″ wide or 108″ drop, the spec answer is “use two panels overlapped” or “look at the Two Pages outdoor track systems for pergolas”. The acrylic body itself does not stretch.

Does Liz have any outdoor-rated lining option that would let me use it on a porch?

No. None of Liz’s 6 linings are outdoor-rated. Cotton, Thermal, Blackout Standard, Blackout Premium and Blackout Thermal 100% are all engineered for indoor climate control: insulation, light blocking, room darkening. Adding a Blackout layer to a Liz panel and hanging it on a covered porch does not turn it into an outdoor curtain. The linen-polyester face fabric still absorbs humidity, still mildews, still fades under direct UV. The 6-lining ladder is for indoor light control, not for outdoor protection.

What promo code works on both Heck and Liz at the moment?

Code JULY runs 20% off sitewide at Two Pages and applies to Heck Outdoor Acrylic and Liz Linen Drape Pleated alike. Two Pages also offers free shipping over $300, which a Heck order of three or four panels clears easily, and a Liz custom order with lining clears on a single panel. Heck ships ready-made in 3 to 5 days. Liz is made-to-order with a 10 to 12 day lead. Both are final sale once configured.

Final Verdict

Coming back to the original question. If the panel is going outside, even on a covered porch that catches morning sun and seasonal rain, Heck at from $99/panel is the only one of the two engineered for the job, and the 4-in-1 Soft Top header handles every common outdoor mounting scenario without a configurator decision. If the panel is staying inside a climate-controlled room and you want a softer linen blend hand, blackout up to 100% via the 6-lining ladder, and 9-header control, Liz at from $59.99/panel is the right pick. Buyers furnishing a three-season porch plus an adjacent living room often order both, swatching first to match the warm-neutral families across the threshold.
