What about those films my home center sells?
All glass warranties are void if any film is applied to the glass surface. Pella® products and integral glazing have been designed to perform beyond industry standards. Any change to the design or glazing may cause glazing and/or product failure. We warrant the product only as it was manufactured and sold.
Low-emissivity, high performance glazing replacement sash are available for most clear-glazed vintage products. Please call our Service Department for quotes and availability.
