Loa by Ronan and Erwan Bouroullec is constructed with thick sIub yarns, which gives the textile a rich, natural, linen-like expression. The open structure provides clear views of the outside. Loa is woven with two solid yarn colours and include both subtle naturals and rich contrast colours.
Loa has a fantastic coarse open structure of 17%. Due to the open structure, the edges can never be completely sealed. This may cause slight fraying at the edges of the textile over time. Never pull the loose threads, this will only worsen the fraying. Should this occur, carefully cut off the loose threads with scissors.

Lightfastness relates to the ability of a textile to retain its colour under light. When testing for lightfastness, samples are exposed to artificial daylight for a specified period.
The evaluation scale ranges from 1 (worst) to 8 (best). An increase of one point corresponds to a doubling of the lightfastness, i.e. the same fading takes twice as long.
Light transmittance indicates the percentage of the visible light penetrating the textile. Densely woven textiles in dark colours usually have a lower light transmittance, whereas loosely woven fabrics in light colours allow more light to pass through.
Flame retardant performance depends on the type of foam used. There are differing requirements concerning the flame-retardancy of textiles dependent on the area of application, country or even region. Our textiles pass the majority of international standards and are also tested for a selection of regional requirements.
Optical properties according to EN14500: 2008
The percentage of solar radiation reflected by the textile.

Optical properties according to EN14500: 2008
The percentage of solar radiation absorbed by the textile.
The percentage of openings in the textile.
Results are based on reference glazing D according to EN1450: 2005.
The percentage of solar energy that penetrates through glazing and textile. A low value means good thermal performance.
Results are based on reference glazing G acc. to EN14501: 2021.
The percentage of visible light penetrating through the textile. If too much visible light is transmitted into a room, it creates brightness and glare problems. For rooms with PC workstations, the maximum recommended light transmission depends on the direction in which the window faces:
North facades: 15–20% light transmission
West and east facades: 2–6% light transmission
South facades: 0–5% light transmission
This is specified by the EU directive 90/270 and ISO 9241.

U-value describes the thermal heat loss (or gain) through a fenestration. The U-value reflects the energy flow through glass and fabric when there is a temperature difference between outside and inside, and is the insulating property. The lower the value, the better the textile's thermal heat insulation properties.
