VELFAC 200 - Quality standards for the window industry; Aluminium standards; Wood quality and treatment

8
VELFAC manufactures windows to meet the very highest expectations. The quality of our parts and materials, with the best
possible standards in manufacturing, combine to provide the VELFAC windows you expect.
We have also implemented some simple guidelines for our customers, which identify quality standards, and what is allowable
for predominately natural materials - wood, aluminium & glass.
Aluminium
Visible aluminium surface defects that are not visible from 3m are acceptable and therefore not claimable. Surfaces should not
be assessed in direct sunlight.

mature slowly - as a result the wood is denser and harder-wearing than standard pine. Wood is a natural material that is often
uneven. We are making very specific demands on our suppliers to get a wood quality, which we can vouch for.
We treat the wood surface following the below mention rules:
• Allsurfacesshouldbetreatedwith100%waterbasedacrylicpaintoracryliclacquer

treatment of resin extraction on page 6
Page 6 describes the maintenance requirements for the wood frame. Special consideration should be given to windows on
South facing facades, in coastal locations, or where there is a high moisture content inside the room. The surface treatment
should be checked at least once per year, and any break in the lacquer or paint should be repaired promptly.
Quality standards for the window industry
Polyester powder coated aluminium is
extremely weather resistant and does not rust
or corrode.
As wood is a natural material, some
variations in finish are unavoidable e.g. where
knots occur. VELFAC wood frames are
laminated to limit these occurrences.

publishes guidelines of modern glazing
