FAQs

What is a framed wall vent, and how is it different from the flush version?

The framed wall vent mounts right on top of your wall or ceiling with a slim, clean metal frame — no mudding or taping required. It's a retrofit-friendly DIY design that installs in minutes with common tools, so it's the easiest way to get a modern, upgraded look. The difference from our Flush Wall Vent is that the flush version is mudded into the drywall so the frame disappears completely, while the framed version keeps a tidy visible frame and skips all the drywall work.

Can I use it on both walls and ceilings?

Yes — every size works for both walls and ceilings, so you can keep a consistent look throughout your space.

Why metal instead of plastic — isn't metal too heavy?

Not at all. We use a lightweight yet heavy-gauge metal that's far stronger than plastic without the added bulk, so it's easy to handle and install but built to take a beating. Metal is also fireproof and heat-safe — your furnace can blow hot air against it all day with no warping, melting, or fire risk like plastic vents can develop over time. And our pin-exact design locks the plate in with pins across all four corners, so it stays secure and will never fall out.

Does it have adjustable airflow?

Yes — every framed wall vent comes with an all-metal adjustable damper so you can fine-tune airflow. The only exception is dedicated return vents, which are damper-free by design.

Can I paint it to match my wall?

It comes in a clean, light finish that looks great as-is, so painting is completely optional. If you'd like an exact match, it's fully paint-ready — paint it to your wall or ceiling colour, or apply wallpaper over it for a seamless blend.

What sizes are available, and how do I measure?

We offer 3x10, 4x10, 6x12, 6x14, 8x14, 10x30, and 14x14 (Exhaust). Measure the duct opening — not your old vent's faceplate — to pick the right size, and check the size guide on the product page. Not sure? Send us your measurements and we'll confirm.
