Asking the Experts: Why Domestic Windows Cause Expensive Damage
Customer Question: “I’m looking to double glaze my static caravan. Can I just hire a local domestic window fitter to install standard house uPVC windows to save money?”
The Short Answer: No, and Here Is Why
It can be tempting to call a local house glazier, but standard domestic uPVC windows should never be installed on a static caravan or holiday lodge. Doing so often leads to costly structural damage and voided park insurance.
The Three Main Risks of Domestic Windows on Caravans
1. Wall Depth Differences
House walls are usually 250mm to 300mm thick cavity brickwork. Static caravan walls are lightweight structures typically measuring only 40mm to 50mm thick. Domestic window frames (usually 70mm deep) stick out far beyond the inner and outer walls, requiring bulky, unsightly timber packing boxes that look out of place and invite water leaks.
2. Weight & Structural Load
Domestic uPVC frames and thick double-glazed units are extremely heavy. Static caravan wall studs and aluminum/vinyl cladding are engineered to support lightweight materials. Heavy house windows strain caravan frames, which can lead to wall warping, roof bowing, and door misalignment over time.
3. Approval & Insurance
MastaGlaze uses 45mm low-profile frames that are fully NCC-APPROVED (National Caravan Council). Installing non-approved domestic windows can compromise structural safety and potentially invalidate your holiday park insurance coverage.
What Does NCC-Approved Mean for You?
National Caravan Council approval guarantees that every frame, seal, and glass unit has been factory-tested specifically for thermal expansion, weight limits, and moisture resistance in static holiday homes.
