Solutions, Highlights and Suggestions

For acoustical uses see our Acoustical Goo © web page

Highly resistant wallboarding for Exotic Fish breeding and Salt Ocean Reef grow operation: Magnesiacore is used for this interior wall boarding project to resist the harsh and demanding indoor environment associated with keeping large elaborate salt water aquarium tanks and habitats with water and air flow piping with auto control systems.

Acoustical wall retrofit and encapsulation achieved with one fast material: Magnesiacore can be applied over existing materials to reduce the cost for demolition, disposal, clean up and related mess. Pictures below show an interior office space refitted with magnesiacore over walls and floors. Walls show a two layer (larger and smaller panels) system with acoustical goo in between. Also shown is a two layer system for the floor over existing carpet. In each case the existing old materials have been encapsulated by the magnesiacore rather than removed and disposed. Save money, time, and trips to the landfill for demolition and disposal.

Radiant Heating Floor Systems: Magnesiacore used in radiant floor heating systems. Dry board materials glued, screwed and/or stapled together will quickly create perfectly flush radiant surface ready to finish immediately. Cut costs further by leaving magnesiacore itself as the finished floor. Other benefits: easier access to piping when removing boards for future repairs or changes (much more difficult with poured concrete).

Non-combustible board that takes brad nails, crown staples, and screws: Magnesiacore is used as support board for asphalt shingles where non-combustible construction is required or desired. While asphalt shingles are designed to be nailed onto plywood or OSB which are combustible materials, Magnesiacore instead allows asphalt shingles to be stapled onto a non-combustible board material. Screw magnesiacore to metal deck or a sloped concrete structure, and quickly staple shingles to magnesiacore.

Non-combustible construction: Use magnesiacore screwed to structural metal decks for floor and roof structures that solve most mandated requirements of building codes for fireproof construction. In wood frame construction, a layer of magnesiacore over the roof sheathing under your shingles adds a measure of life safety protection against the dangers of roof fires.

In non-combustible assemblies magnesiacore allows for hot elements in wall systems such as electrical lighting and wiring; as pictured below with high quality wall finish that cannot be applied to paperfaced gypsum or other soft combustible materials. This is a feature wall of an architectural office. Deep blue finish, heat resistant without feathered joints or visible imperfection.

Laminated with other materials as in balcony applications with railing and divider infill panels. In this example prefinished aluminum sheets are laminated to magnesiacore on one side, allowing textured coatings or other finishes to match the building façade.

Substitute in steel construction concrete deck composite floors to eliminate using poured concrete over metal floor deck in multi-story steel buildings. Apply magnesiacore directly to the metal deck to substitute the wet concrete infill. Magnesiacore is ready to receive all types of flooring immediately, with a perfectly smooth surface, without trowel marks from workmanship, and without pouring and refinishing wet concrete slabs. Avoid the high cost, mess and labor to pour and refinish concrete. Obtain a lighter structure. Optionally, use sandwich panels (two layers of laminated magnesiacore) for the infill material to provide insulation, temperature and sound attenuation benefits.

Light curvatures can be achieved: Magnesiacore has the flexibility to bend to a slow shallow radius as in the vaulted ceiling shown below. Jointing in this case is achieved by using plastic "H" molding at all panel junctions without filling or tape. Equally suitable for sharp elaborate angular ceiling shapes:

Concrete Form Liner Surface Finish: Magnesiacore can be used inside formwork as a finished lining that will bond to the concrete naturally. Concrete and most cement materials will bite into magnesiacore's pores for a strong natural bond. Note: the concrete juice that seeps through the panel joints can be easily scraped off with a sharp blade to reveal the natural undamaged magnesiacore panel and perfectly flush joints.

Exterior Panel Finishing Systems: Magnesiacore has numerous applications for exterior wall panel finishing systems. Contact us with your requirements and we will work with you to develop a specific system detailed for your project.

Durable Versatile Material: Magnesiacore has the flexibility to be a paint substrate, a stucco substrate, and a tile backer on the same wall face without changing substrates to avoid joints between dissimilar materials. Cut and work with carpentry tools for simple design options not available in any other all-in-one dry board material. Below is a simple wall using 3/8" (9mm) grey as a base with 1/2" (12mm) white screwed over it to create raised panels, creating solid wall panel detailing that combines both (buff) paint and (white) stucco texturing finish…all over the same substrate. This would otherwise require different highly skilled trades to apply different materials and jointing. The end result is a 20 MpA (3000 PSI) concrete-hard, plaster-like wall surface that is fireproof and resistant to water, moisture, organisms, salt and impact damage. Increased resilience to freeze-thaw cycles reduces maintenance and extends longevity.

Stucco Substrate: Traditional stucco applications may use an insulating material board to provide a thermal break over a sheathing material on stud work, over which lath (galvanized wire or mesh) is applied. This is then followed by several layers of wet cement plastering to dry into a hard base. The base coat is made in layers of wet mix, hand applied, troweled-on material that results in a substrate with varying properties and quality depending on the tradesman. Using magnesiacore completely eliminates these laborious steps, different materials, and drying downtimes. A consistent quality substrate is guaranteed as soon as the board is screwed onto the wall to receive stucco or paint.

Magnesiacore provides an excellent surface for adhesion of stucco. Stucco jobs can be done in one quick continuous process by mechanically fastening magnesiacore to the structure using appropriate thermal break foam behind the board. The application of flexible decorative finishing goes on directly and immediately without waiting for plaster base coats to dry. Does not require a great deal of skill to create the uniform base surface, and reduces the amount of costly acrylic stucco material required to complete and make uniform renders. For panelizing and embossing, layers of magnesiacore can be used and edges can be made true or routered without corner and edge trimming materials..

Pictured below is an example of lightweight steel framing using magnesiacore as exterior cladding and interior wall board. Achieve quality lightweight structures with maximum functional strength. The same character and functionality of heavier construction methods with much less construction time and material.

FAST and EASY Plaster Hard Walls: (Interior or Exterior) Gypsum based board materials suffers from structural weakness with a separate friable core and paper or plastic facings that require taping to reinforce joints over the front and cannot be used on exteriors. Using Magnesiacore board provides a solid integral plaster-like wall that can be adhered together at the edges without reinforcing over the face of joints. High impact resistance in addition to fireproofing and moisture resistance suitable for interior or exterior use.

Flooring applications that create sound dampening floors for office and commercial environments:

Basement Dry floor component Magnesiacore is used as pictured below to create a raised dry basement floor subfloors over a cold damp concrete slab. In this case two layers of magnesiacore are glued and stapled together to form a rigid mass over high density waterproof foam insulation. Performs both as an insulated floor and dry floor that will not rot as well as provides high acoustical attenuation.

     

As general purpose exterior panels magnesiacore has a practical application to encapsulate pressure chemical treated wood lumber (reducing physical contact with arsenic releasing surfaces) thus allowing the common pressure treated wood decks and railings new life as support for our hard flexible concrete-like surface. (Note* USA banned the use of virtually all Arsenic Wood Preservative Treatments in new residential construction starting in the year 2004)

The magnesiacore surface is smooth and dense yet finely porous thus receiving all coatings with a higher degree of adhesion than most other materials. In stucco applications considerably less stucco material is required to achieve a more uniform surface for saving in the cost of the finishes. Finishing options also include, stucco, painting, staining, or left natural with a gloss coatings or clear penetrating sealers.

As an exterior wall cladding magnesiacore can be used as a faster alternative to stucco, block, brick or siding left in natural color with a clear weatherproof sealer, or stained for different effects. For a paintable exterior wall surface it can be used textured or smooth. Shown below is an exterior wall assembly made using natural T&G panels representing  32" x 48" (81cm x 122cm) in 15mm thickness and dramatic reveals. Panels are joined by buttered T&G joints and exposed countersunk screws.


Alternatives for fasteners (exposed or concealed) while providing unlimited choice for architectural coursings, reveals, ornamentation, and embossing to permit diverse designs by working with three dimensions of a wall's surface. Machined & painted faux brick shown below.

POP RIVET FASTENERS to apply aluminum and metal trim to magnesiacore for more options and versatility not achievable with other types of construction board.

T&G JOINTING: Magnesiacore can be shaped to permit using "tongue and groove" joints to eliminate taping and filling to speed up construction. Pictured below is a wall made using T&G in 1/2" x 32" x 48" (12mm x 810mm x 1220mm) panels that can be prime painted before the end of the same day the wall started. Left with a natural finish you could have lunch in a room started after breakfast.

Using rounded bullnosed edges as pictured below provides a different method of installation to eliminate taping. Since magnesiacore is a uniform solid material without a separate facing material it can be bonded together by the edges using a variety of different type and strength bonding fillers not limited to drywall joint compounds.

For fast easy heavy duty ceramic tile backerboard: Laminated over a sub-floor or over existing old flooring, 1/4" (6mm) (or 3mm 1/8" in certain instances) of Magnesiacore is used with flexible adhesives for laminating to receive tiles. This replaces the wire lath and cement screeds, mud coats and plastering work that requires downtime and skilled trades over the subfloor. Hard tiles are applied over the magnesiacore using normal floor mix adhesives. Common labor can apply the magnesiacore while a tile setter lays the tiles in sequence. Different thickness are available in one millimeter increments from 3mm to 20mm or thicker by laminating multiple layers of magnesiacore.

Considerable savings in floor mix material are obtained using finer tooth ceramic floor mix spreaders which is made possible by magnesiacore being smoother and more uniform than other systems. (1/4") 6mm of magnesiacore pays for itself and saves money by increasing the floor coverage obtained from a bag of floor mix adhesive. Using a 1/4" tooth spreader rather than 1/2" tooth, a four fold increase in coverage can be obtained. (i.e. one bag of floor mix provides the coverage of four bags)

Impact resistant suspended ceiling tiles: Pictured is an application using 6mm (1/4") magnesiacore cut to 24" x 24" (610mm x 610mm) ceiling tile size in natural chalk white. Apart from higher impact resistance magnesiacore can be left natural, painted, stucco, coated or laminated to provide unlimited options to T-Bar suspended ceilings. With variety of thickness, various densities provide solutions and impact resistance beyond what is available with fibrous, cellulose or soft tiles.

Foundation wall insulation protection board for cold climates subject to ground swelling and soil heaving from freeze and thaw cycles. Soil movement between cold winters and hot summers can erode and wear away buried rigid insulation over exterior foundations walls. We recommend a minimum of 3/8" (9mm) thick for protection board for buried insulation for most types of soils subject to these effects. Withstands pressure of frozen earth pushing against exterior foundations preventing damage to insulation.

Existing Wall Refinishing System: Magnesiacore resistance to salt and chlorine makes it an ideal wallboard material for protection covering and/or re-facing for masonry or concrete surfaces that are prone to salt damage in costal areas, seaside buildings and for the interior of swimming pool building walls and ceilings that otherwise undergo periodic maintenance for salt or chlorine damage. Magnesiacore mechanically fastened to walls using Stainless Steel (SS) Masonry Screws and SS Clips provides a quick and easy, less expensive, and more durable solution to other more costly protective coatings. On-going  maintenance procedures over the long term results in significant savings to the building owner by reducing the frequency of retrofits.

For the signage industry in place of high end exterior grade plywood and composite panels Magnesiacore provides a novel and suitable alternative for sign boards, bill boards and signage panels, making an economical alternative to exterior sign plywood. As machinable material, use for carving and cut out or routered signs render interesting stone like effects. Usable as a exceptional and durable paint substrates for watercolors, oils, acrylic, pastels and most other graphic arts medium.

Finish Flooring: Magnesiacore is suitable as a novel finishing material for floors. By laminating to sub-floors with adhesives; or using concealed fasteners, nails or screws, with visible plugs etc., and grouted or otherwise with reveal jointing Magnesiacore can receive sealers directly for an attractive, interesting and economical floor finish. Since the color is throughout the material and not a surface feature this allows for sanding, refinishing and to regenerate worn floor surfaces over time.

Skin Material for paint grade, veneered and pre-finished doors or paneling:
The inertness and moisture management properties make
Magnesiacore the ideal material for use as core or skin materials for doors (interior and exterior), countertops and cabinets, especially those that may become in contact with water or humidity such as kitchens, baths, public washrooms, sporting facilities, pools, change rooms, showers, vestibules and other interior or exterior applications.

As hot applied roof membrane base sheet or as a roofing ballast; magnesiacore does not burn and will take flame applied and hot roofing without being adversely affected. Under roofing it will not deteriorate if it gets wet making roof leak repairs easier without water damaged gypsum or other materials that need replacement. Magnesiacore dries out unharmed after getting wet. As embedded ballast on top of soft roof membranes it provides a walking surface for  balconies and roof top patios while replacing the stone ballast as UV protection.

For wood frame construction: Magnesiacore provides a concrete like floor with ease by laminating over plywood floor sheathing. Wood frame structures receive the added benefit of fireproofing between floor levels as well as acoustic and thermal resistance improvements that plywood does not provide. Tendency for squeaky wood floors is reduced with Magnesiacore being more rigid than plywood. Separating living spaces of homes from the wood structure creates fire separation between rooms. If a fire starts in a room that has Magnesiacore on the floors, wall and ceilings; fire can be contained within the room for an hour or more giving ample time for smoke alarms and intervention to limit the extent of fire damage to the contents of the room, minimizing the risks of fire spreading to structures and other rooms.
