Pros
- Addresses structural masonry essentials like foundation footings and bricklaying
- Explains drafting principles to help builders minimize smoky outdoor fireplace operation
- Includes three full build plans to jumpstart outdoor hearth projects
- Convenient paperback dimensions make it easy to carry to job sites and supply yards
Cons
- Provides instructional plans only; all masonry tools, stone, mortar, and materials must be purchased separately
- Does not substitute for municipal building permits, setback regulations, or local fire safety codes
The core instructional material focuses on the foundational steps required for enduring outdoor masonry. It details the construction of proper footings to support heavy stone and brick structures, addressing ground stability and structural durability. In addition to structural masonry advice, the text highlights safe drafting techniques, which are critical for outdoor fireplaces where variable wind patterns and flue proportions dictate whether smoke exhausts cleanly upward or rolls forward across seating areas. The guide also supplies three complete build plans to give builders concrete layout dimensions and construction frameworks.
Published in an independently printed paperback format, the book measures 6 inches wide by 9 inches tall with a slim 0.41-inch profile. This standard manual size makes it easy to transport between an indoor planning desk, a masonry supply yard, and the outdoor jobsite. The text focuses on traditional materials such as stone, brick, and mortar, providing design concepts and step-by-step guidance rather than branded components or proprietary fireplace inserts.
Before starting an outdoor fireplace project based on these plans, prospective builders must evaluate site-specific constraints such as property lines, overhead tree canopies, prevailing winds, and clearances to combustible structures. Heavy masonry fireplaces require solid, frost-depth footings that vary widely depending on local soil conditions and regional climate. Furthermore, while the book outlines safe drafting and masonry fundamentals, it cannot account for specific municipal zoning ordinances, local burn bans, or required building permits. Consulting local building departments and utility locating services is an essential preliminary step before excavation.
For homeowners and DIYers who want to build a custom stone or brick outdoor fireplace from the ground up, this reference provides structured guidance on masonry techniques and chimney drafting principles. It will not suit those seeking an off-the-shelf, ready-to-burn metal outdoor fireplace or a quick gas-table installation, as masonry construction demands substantial physical effort, specialized tools, and raw materials. For those committed to designing their own backyard hearth, the included build plans and structural fundamentals make it a worthwhile project planning companion.
This guide addresses outdoor hearth planning by emphasizing proper ground footings to prevent settling and structural cracking over time.
Builders should always verify local zoning rules, clearance codes, and open-burning ordinances before breaking ground on any outdoor masonry fire project.
It features physical product dimensions of 6 inches in width, 0.41 inches in thickness, and 9 inches in height, making it compact enough to fit into a tool bag, glove box, or workshop bookshelf.
The included plans provide conceptual dimensions for outdoor masonry fire features, though individual project footprints should always be verified against available yard space and local setback requirements.
Pros
- Layered fabric construction pairs sturdy Oxford cloth with dual cotton batting to physically buffer airflow
- Integrated 12-magnet perimeter enables quick placement and removal on compatible metal surrounds
- Folds and stores easily without taking up significant closet or hearth space
- Includes adjustment pins to fine-tune the blanket size for non-exact firebox openings
Cons
- Not fire-retardant and must be completely removed before lighting any fire or exposing the hearth to heat
- Requires a magnetic iron frame and will not stick directly to brick, stone, wood, or non-ferrous metal trim
The CADARA Magnetic Fireplace Draft Cover is a specialized hearth accessory designed to limit unwanted air exchange through an idle chimney. Geared toward homeowners and renters dealing with chilly floor drafts, soot odors, or summer cooling loss, this 39-inch by 32-inch blocker blanket covers the firebox opening to create an air barrier. Because it relies on magnetic adhesion, it is intended specifically for indoor fireplaces featuring an exposed iron or steel surround that attracts magnets.
Constructed from a dense outer shell of Oxford cloth and filled with two layers of insulating cotton, the blanket provides a physical barrier against airflow moving up or down the chimney flue. Around the perimeter, 12 embedded magnets secure the fabric flat against a compatible metal frame. The product package also includes small mushroom-style adjustment accessories, which allow users to gather and pin excess fabric if their hearth opening is slightly narrower or shorter than the blanket's full dimensions.
Setting up the draft cover requires confirming that your fireplace frame is magnetic iron. Homeowners with bare masonry, brick, stone, tile, or non-ferrous aluminum surrounds will find that the magnets do not adhere without supplementary mounting solutions. When a suitable iron frame is present, positioning takes only moments by aligning the magnetic edges flush against the metal to minimize side gaps. Weighing under 1.5 pounds, the flexible fabric body rolls up or folds flat when not in use.
A critical safety limitation is that this draft blocker is not fire retardant. It must never be deployed while a fire is actively burning, nor should it remain on the fireplace when hot embers or high residual heat linger in the firebox. Operating a wood-burning, pellet, or gas fireplace with the blanket attached creates an immediate fire hazard and blocks necessary exhaust ventilation. Users must remove the cover entirely before lighting a fire and reinstall it only after the hearth has completely cooled.
For households looking to curb seasonal draft issues and stabilize room temperatures when the hearth is dormant, the CADARA draft blanket offers an affordable, non-permanent barrier. It functions well as a seasonal draft stopper or a daily thermal cover between winter fires, provided your fireplace has a compatible iron surround and you follow strict safety habits by removing the cover before every burn.
The CADARA draft cover measures 39 inches in width by 32 inches in height with a profile thickness of roughly half an inch. It is engineered to attach directly to ferrous metal surfaces via 12 integrated magnets placed around the perimeter edges.
Before purchase, verify that your fireplace opening has an iron or magnetic steel face frame. Surrounds made of brick, rough stone, marble, tile, or painted wood will not hold the magnets. In addition, fireplaces fitted with aluminum doors or brass trim lack the magnetic attraction needed to secure the blanket without separate adhesive or hardware.
For fireplaces that are slightly smaller than the 39 by 32 inch dimensions, the supplied mushroom-style adjustment clips allow you to fold over the outer edges and secure the excess fabric. Always measure the exterior dimensions of your metal frame to ensure the perimeter magnets have full contact with flat metal.
This fireplace draft stopper is manufactured from standard Oxford cloth and cotton batting, meaning it is combustible and not fire retardant. Never install the blanket over an active flame, glowing coals, warm pilot lights, or a hot firebox.
Always remove the draft cover completely from the hearth area prior to kindling a wood fire or switching on a gas or electric appliance. Ensure the flue damper is opened and the firebox is fully ventilated before ignition.
When extinguishing a fire, allow the firebox, grate, and metal surround to cool to room temperature before reattaching the magnetic blanket. For cleaning, wipe down the exterior fabric as needed and fold or roll the blanket into a dry location during the active burning season.
