Installation
Window Installation in 8 Steps: What to Ask Your Installer
The 8-step procedure
- Preliminary inspection: dimensions, plans and the condition of the supporting structure are verified.
- Removal (if applicable): careful removal of the existing product and clean-up of the opening.
- Frame fixing per the manufacturer’s specifications and EN 14351-1.
- Perimeter insulation with polyurethane (PU) foam, inside and out.
- Airtight sealing with quality silicone, neutral or acetic depending on the surface.
- Mechanical adjustment: checking and calibrating mechanisms, hinges and tracks.
- Final inspection: visual, functional and thermal check of every unit.
- Site clean-up: removal of materials and waste from the site.
Client checklist
- Were measurements taken on site and have you approved the specification sheet?
- Are removal and clean-up included in the quote?
- Is perimeter insulation and sealing used on both sides?
- Are all openings and locks tested before handover?
- Do you receive a handover protocol and warranty certificate?
Handover and warranty
After the final inspection, both parties sign the handover protocol. The warranty starts from that date: 5 years on the product and 24 months on installation.
What can go wrong
- Without good perimeter insulation: cold and condensation around the frame.
- Weak silicone: water and air ingress.
- Insufficient mechanism adjustment: windows that close badly.
- Inaccurate measurements: a window that doesn’t fit the opening.
