CARE &

MAINTENANCE

Once you have clearly indentified the type of product follow the general guide-
lines set out below for either timber or aluminium external finish and the
internal timber finish.

EXTERNAL MAINTENANCE OF TIMBER
Rationel AURA, DOMUS and PATUS
We recommend that you wash the frames and sashes twice a year to remove
dirt and other kinds of impurities. Use water, mixed with a mild household
cleaning product.

A visual inspection should also be carried out once a year, to check the external
surfaces are free from any splits or cracks in the paintwork or timber. UV rays
from the sun can also effect the surface treatment - especially on south and
west facing elevations.
Properties without overhanging eaves will also be more exposed to the UV rays.
Any cracks in the paintwork or timber, will allow moisture to penetrate into he
product and over time cause decomposition of the timber.
When carrying out remedial works to your windows and doors make sure that the
humidity of the timber is between 15% to 18% and the ambient temperature
between 10 to 20°C. To avoid the effect of dew also avoid early mornings and
later in the day, to enable paintwork to dry.

EXTERNAL MAINTENANCE OF ALUMINIUM
RATIONEL AURAPLUS, ALDUS AND PATUS+
Windows with external aluminium cladding require minimal maintenance, and
cleaning externally twice a year.

If the window has been subject to vandalism or any other kind of physical
damage, small scratches can be repaired using a polish. In cases of deep
scratches, oxidation will automatically close ”the wound” and prevent corrosion.
Damage like this can be difficult to repair without leaving a ”scar”, so the
advice is to leave the scratch; it will not affect the life span of your window.
