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.
Wood
Pine trees used in the production of frames for VELFAC windows are grown in North-European forests, which mean they
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
• Surfaces, edges and joins must be uniform in color and gloss and be smooth to the touch
• Because wood is a natural product, there may be structural and gloss variations, scratches and other normal wood variations
(e.g. in connection with knots)
• Wood contains natural resin. During the first 3-4 years, resin leakage may occur and crystallise on the wooden frame. See
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.
