  • Unique gradual satin on the market with the high quality acid etching technique.

  • Different versions possible according to needs.

  • The matt zone is highly scratch and stain resistant.

  • SEVASA satin is long-lasting and easy to clean.

  • It is resistant to damp and can be exposed to both the sun and artificial light. Unchanged by time.

  • Easy transformation: cutting, bevelling, curving, drilling, tempering, laminating and suitable for double glazing.

  • Guaranteed homogenous quality and high production capacity.

  • SEVASA holds the quality certificate ISO 9001 and ISO 14001 in environmental quality.


  • (*) We suggest seeing a sample of the transparent zone treated.

  • Store the glass in a dry place to prevent oxidation and protect from dust.

  • High resistance to scratches and stains of the matt area is not guaranteed in cases of abrasions with machinery or chemicals.

  • Clean with clean water. Do not use abrasive products.

  • Just like any other satin, care must be exercised when handling, particularly the matt face. Place the glass on a clean cutting table to protect the satin. It is recommended you position the glass satin side up on the cutting table.

  • In exteriors and double glazing it is recommended the treated side be positioned inside to preserve the initial aesthetic. For exterior use of the treated side, you can also see the SEVASA Antiscratch line.

  • In wet zones (shower screens, shower cabins, etc.) you are advised to install the glass with the treated side outwards: the glass will be transparent until it dries.

  • When Graduel® glass is installed correctly, no specific precautions are required. SEVASA satin is untouched by time and it does not degrade or blur.

  • Transformation observations (*):

  1. Laminate: the treated side must face outwards.

  2. Straight, circular, bevelled, polished, perforated, grooved and V-bevelled: It is worked like float glass, on a clean cutting table. It is recommended you position the glass satin side up on the cutting table.

  3. Curve: it can be curved on both sides of the float.

  4. Serigraph: both sides can be serigraphed.

  5. Silvered layer: Preferably on the untreated side.

  6. Lacquered layer: Preferably on the untreated side. See LuxMat Laquée

  7. Double glazing: the treated side should preferably be faced inwards in the assembly for ease of maintenance. The use of silicone for the double-glazing joint is not permitted when the satin side is in position 2 or 3.

(*)  Transformation not hadled by SEVASA. These recommendations are guidelines and do not substitute the criteria of the responsible professional/company.

Customised Production: specific according to your design, production, services and logistic needs.
