Hello Sun prices each project after measuring your windows and selecting fabric and hardware; you receive a written quote rather than a fixed price list, because every installation is made to measure.

Fabric selection
Zebra blinds use alternating sheer and solid fabric stripes on a single shade, letting you adjust light and privacy by shifting the stripes into or out of alignment.
Roman blinds fold into soft horizontal pleats when raised, giving a more tailored, fabric, forward look compared to the flat roll of a roller blind.
Roller blinds offer a clean, compact window covering that rolls up fully out of view, making them a popular choice for a minimal, modern look in living rooms, kitchens, and offices.
Fire, resistant curtains are treated or woven to resist ignition and slow the spread of flame, and are commonly specified for hotels, offices, restaurants, and other commercial spaces with safety requirements.
Acoustic curtains use dense, multi, layered fabric that absorbs and dampens sound waves, reducing both echo inside a room and noise coming in from outside.
Thermal curtains use insulated lining to reduce heat transfer through the window, helping keep interiors cooler during Dhaka's hot months and reducing strain on air conditioning.
Solid color curtains offer a clean, uniform look that works well when you want the curtain to complement rather than compete with patterned furniture, rugs, or wallpaper.
Textured curtains are decorative home fabrics. Hospital curtains are medical, grade cubicle drapery: antimicrobial and antibacterial treatments, fluid, repellent and stain, resistant finishes, and inherently flame, retardant construction to NFPA 701 and BS 5867 for clinics and hospitals, not a simplified residential texture look.
Textured fabrics have a woven or embossed surface pattern, like linen weaves, jacquard, or ribbed finishes, that adds visual depth and tactile interest compared to a flat, smooth fabric.
Sheer curtains filter natural light while maintaining daytime privacy, making them a popular choice for living rooms and any space that wants a soft, airy feel without blocking light completely.
Our textile consultants evaluate three key factors: natural light orientation, privacy requirements, and interior architecture. For living areas, we often recommend light, filtering sheers or minimalist linens. For bedrooms, 100% triple, weave blackouts or acoustic drapery provide optimal restful environments.
We curate architectural linens, daylight, diffusing sheers, acoustic dimouts, 100% blackout linings, and textured woven fabrics imported from Belgium, Italy, Turkey, and Japan.
Yes, coordinating upholstery and curtain fabrics is something your consultant can help plan during your studio visit.
Yes, their fabric folds and tailored finish make Roman blinds a common choice in more formal or upscale interior styles.
No, thermal insulation works in both directions, so in a hot, humid climate like Bangladesh, thermal curtains primarily help keep outside heat from entering the room.
Generally yes, a single solid color is easier to coordinate with an existing color scheme than a patterned or textured fabric.
Yes. They are engineered for hospital wards, ICU / CCU cubicles, private patient suites, diagnostic clinics, and wellness recovery centers where hygiene, flame safety, and commercial laundering matter.
Yes, kept in neutral or muted tones, textured curtains can add subtle depth to a minimalist room without introducing bold pattern or color.
Thermal, lined curtains reduce heat gain from sun, facing windows, while light sheers keep rooms bright without trapping warmth. For bedrooms, layer blackout over sheer. Choose fabrics that resist humidity and mildew. Hello Sun consultants recommend by window direction and room use.
Yes, zebra blinds are a newer style favored in contemporary interiors for their clean lines and flexible light control in one shade.
Not necessarily, fire, resistant treatments and weaves are available across a range of colors and textures, so the safety feature doesn't have to compromise the interior look.
No curtain fully soundproofs a room, but acoustic curtains meaningfully reduce noise transmission and echo compared to standard fabrics.
Healthcare, appropriate neutrals, such as whites, greys, soft blues, and muted tones, chosen for clinical environments where calm, cleanable surfaces matter more than decorative patterning.
Textured fabrics pair well with modern furniture by softening clean lines and adding warmth without competing with the furniture's shape or color.
Lightweight sheer fabrics are generally breathable and dry quickly, which suits Bangladesh's humidity, though the specific material should be confirmed with your consultant.
Fabric durability depends on the specific material chosen; your consultant can recommend options suited to daily household use versus more delicate, formal pieces.
Three made, to, measure lines: roller (solar screen or blackout), Roman (soft horizontal fabric folds), and zebra (dual sheer and solid bands). Each can be specified with manual or motorised control during consultation.
Yes, the multi, layered construction that gives acoustic curtains their sound, dampening properties makes them noticeably heavier than standard curtain fabric.
Fabric weight varies by collection, from lightweight cottons to heavier weaves; your consultant can recommend a weight based on the room and desired drape.
Yes, thermal lining can be paired with a range of face fabrics so you don't have to compromise on the room's look to get the insulation benefit.
Yes, solid curtains are one of the most versatile options and can be styled for either traditional or contemporary interiors depending on color and hanging style.
Yes, blackout lining can be paired with a range of face fabrics, so you don't have to sacrifice style for light control.
Sheer fabrics are available in a range of neutral and soft tones designed to complement most interior palettes, your consultant can show swatches during your studio visit.
We source directly from specialized textile mills in Italy, Belgium, Turkey, and across Europe. Each fabric is tested for colorfastness, anti, sagging stability, and durability under Dhaka's tropical climate.
Blackout
Solar screen blinds filter harsh sunlight, reduce heat gain, and preserve outside views during the day. Blackout roller blinds use opaque fabrics with zero light transmission, providing complete darkness and night, time privacy.
Blackout curtains use a tightly woven or coated fabric designed to block the large majority of external light, making rooms significantly darker than with standard curtains.
By sliding the alternating stripes, you can move smoothly between a fully sheer, softly filtered, or fully blocked, out view without swapping fabrics.
Light control depends on the fabric chosen, sheer, light, filtering, and blackout roller fabrics are all available depending on how much light you want to block.
Yes, blackout curtains are one of the most common choices for bedrooms, particularly for shift workers, light sleepers, or rooms facing direct morning sun.
Yes, layering sheer and blackout curtains on the same track is common, giving soft daytime light through the sheer layer and full darkness at night with the blackout layer.
Most thermal linings have a light, blocking effect similar to blackout curtains, though the primary purpose is temperature control rather than darkness.
Blackout fabrics are typically thicker and denser than standard curtains, so they also provide some insulation against heat and outside noise, though not to the level of dedicated thermal or acoustic curtains.
Sheer curtains alone offer limited privacy after dark once interior lights are on, which is why they're often paired with a blackout or lined curtain for evening use.
