Technical textiles - focused on solutions

Almedahls has for more than two decades researched how textiles affect sound, together with institutions and experts we have developed what can most easily be described as a formula. By combining the right data, we can go from reducing noise to designing the sound in a room, so it’s experienced the way you want it. We call it AlmedalHz™.

At Almedahls, we have over two decades of experience researching the effects of textiles on sound. Working with institutions and experts, we’ve developed AlmedalHz™—a unique formula that allows us to go beyond simple noise reduction. By integrating precise data, our textiles are designed to shape the acoustic experience within a space, creating an atmosphere tailored to your needs.

Because standard sound absorption measurements for textiles are limited, we’ve utilised recognised values to support accurate acoustic planning. Our products are measured with alpha values from 0.00 to 1.00 and categorised into sound absorption classes, from A to E, where A offers the highest level of absorption. This classification, however, only tells part of the story. Effective room acoustics come from combining sound-absorbing materials with varied properties, strategically positioned across surfaces to suit your environment’s needs.

Our acoustic textiles are engineered for public spaces, blending functionality and style to enhance both auditory and visual comfort.

Acoustics play a crucial role in well-being within public spaces. In rooms without sound-absorbing materials, reverberation time increases, making the space feel acoustically harsh as sounds linger. This extended reverberation reduces speech clarity and amplifies irrelevant noise, creating a challenging environment. While a long reverberation time may benefit activities like choir singing, most public spaces benefit from a more controlled acoustic atmosphere where sound fades more quickly.

When sound meets a surface, part is absorbed, and part is reflected. The material’s properties determine its absorption capacity, making sound-absorbing textiles highly effective in offices, canteens, conference rooms, and reception areas. Our approach starts with the unique needs of your space, whether inspired by a design detail, a theme, or a desire for something truly distinct. Working together, we blend our expertise with your vision to create a balanced, functional sound environment tailored to your space.

Sound tests according to SS-EN ISO 354 have made it possible to divide the fabrics in different audio classes from A-E depending on how well they absorb sound.

Class A-B

Class A αw: 0,9 to 1,0

Class B αw: 0,80 to 0,85

Class C-D

Class C αw: 0,60 to 0,75

Class D αw: 0,30 to 0,55

Class E

Class E αw: 0,15 to 0,25

Effective light regulation has a powerful impact on a room’s atmosphere, particularly in workplaces where balanced lighting is essential. Specialised functional fabric solutions are needed to manage daylight—softening it without completely blocking it out. This approach reduces screen glare, supports visual comfort, and creates a welcoming environment that promotes productivity and well-being.

Simplified textile selection for care environments

As a leader in product and concept development, Almedahls has created a classification concept to make it easier for architects and designers to select the right textiles for care and sensitive environments. Our Hygiene Classification concept enables you to quickly find the ideal product for your specific project, ensuring the highest standards of hygiene and functionality.

• Curtains can be installed and must be washed once a year or when visible dirt appears.
• Staff and conference rooms may be equipped with washable textiles.

Usage areas:

• Areas without patient presence.

Enhanced cleaning and hygiene

Requirements (in addition to Class 0):

• Textiles and upholstery must be suitable for wiping and disinfecting or be removable and washable.

Usage areas:

• Waiting rooms
• Day areas
• Elevators
• Corridors
• Public restrooms
• Staff rooms
• Special-purpose rooms
• Meeting rooms

Intensive cleaning and specialised usage

Requirements (in addition to Class 0 and 1):

• Textiles and upholstery must endure frequent cleaning with specified agents and help identify stains or fluids.
• Solar and blackout curtains should be installed between glass panes or externally; roller blinds must withstand cleaning and sanitising.
• Operation must use wipeable bead chains or motorised controls.
• Curtains must be washable at 70°C, with a minimum of two washes per year or after contamination.

Usage areas:

• Wards / treatment rooms
• Examination rooms
• Laboratories
• Hygiene areas in specialised housing
• Dental care

Sterile environments

Requirements (in addition to Class 0, 1, and 2):

• No curtains or solar protection are allowed.

Usage areas:

• Operating rooms and surgical suites
• Sterile technical units
• Dialysis and endoscopy units
• Intensive care units, including neonatal care
• Intervention laboratories
• Infection wards
• Patient rooms for highly infectious patients

Our textiles are designed for demanding healthcare environments where hygiene is critical. Our fabrics can be washed at temperatures up to 70°C, effectively combating bacterial spread.

• Washing Instructions: The recommended 70°C washing temperature is specified on the care label.
• Tested Durability: Laboratory testing at 72°C confirms that our fabrics maintain their quality and functionality even under repeated high-temperature washing.

Almedahls’ Hygiene Concept offers a complete series of solar protection fabrics that meet the strictest hygiene standards, including transparent, translucent, and blackout options.

As a trusted supplier to healthcare environments, we ensure that our fabrics can be surface disinfected using solutions containing 45% isopropanol and surfactants. This guarantees durability, compliance, and the highest levels of cleanliness.

It’s well known that interior design impacts how we feel—from creating a sense of safety to energising a space and shaping brand perception. Since the 1950s, Studio Almedahls has been at the heart of our company, developing timeless and contemporary designs in colour and pattern. Today, we’ve broadened our vision, embracing a comprehensive approach to interior architecture to help you create “a better place to be”, using our technical textile.

At Almedahls, we prioritise lasting quality in both product development and colour selection, blending timeless appeal with a modern touch. By continuously refining our colour palettes, we ensure our textiles remain relevant and adaptable to contemporary design needs. Our extensive, co-ordinated colour ranges make it easy for clients to harmonise our textiles with modern architectural materials, creating vibrant interiors or calm, balanced spaces. Like music, it’s the interplay of shades that shapes the atmosphere.

Our colour palette is grounded in cool and warm neutrals, from crisp whites to the deepest blacks, inspired by natural elements like sky, clouds, stone, earth, wood, and metals. To complement this neutral base, we’ve developed a versatile, well-balanced selection of soft pastels, stimulating mid tones, and a few bold, energetic hues, bringing both harmony and character to any space.
