Timber Joinery Warranty

Handle the window unit carefully and inspect for any damage or manufacturing faults.
All painting and oiling should be done professionally.
Seal all surfaces with the first priming or sealing coat using an oil-based primer, paying attention to the top and bottom edges.
When painting, a four-coat system should be used (primer, undercoat, and two top coats).
For clear finishing, a 3 or 4-coat system should be used. The lighter the colour, the better, as dark colours attract heat, leading to cracking and shrinkage, voiding the guarantee.
To seal the beading on a window or sash with glass, paint or stain at least 1mm onto the glass surface.

5-Year Guarantee The exterior window guarantee is valid for 5 years, provided the following conditions are met:

Coat all sides, including top and bottom, immediately according to paint manufacturer recommendations.
Use only oil-based paint.
Only use paint with a light reflective value over 40%—NO DARK PAINT.
