Plastic Diffusers

Non-corrosive plastic ceiling registers, vents and air returns are ideal for wet and humid areas such as kitchens, locker rooms, showers, indoor pools, dishwashing areas and medical MRI rooms. Larger 2'x2' are made to be installed into a ceiling grid system while our smaller 12" x 12" plastic vents are ideal for rest rooms and showers.

Ceiling Repairs

Black soot and dust on your ceiling tiles can be expensive and difficult to clean or replace. Avoid damage to the ceiling tiles surrounding your ceiling diffusers by installing our unique ceiling dust deflectors. 1800ceiling.com carries many innovative repair products and even offers How-To videos for the do-it-yourselfers.

Air Diverters

Block and redirect annoying drafts from square 2'x2' ceiling diffusers and linear ceiling vents. Our diverters install quickly without the need for tools. Stay comfortable while sitting at your work station. Ideal for offices, restaurants, commercial kitchens and medical facilities.
