1958 Ceiling Louver Replacement

The White Polystyrene Egg Crate Louver match perfectly to the original egg crate louver in the kitchen ceiling of our original 1958 mid century modern house. The old louvers have yellowed badly over time and need to be replaced. These new fresh louvers will transform the space.

Good service, not shipping

I ordered from 1800 ceiling for the first time but I did pay almost $80 for 2 day shipping. Even though we had some snow, I did anticipate a delay for about 2 days but it turned out to be a week. Don't spend the extra money for rush delivery because someone made some extra on shipping rather than rushing it out. But on the interim the support and business professionalism was very good! Great products too

Bough to replace 3/8 units that broke with heavy winds, these held up during last two storms.
