Why is Magnesiacore Better

 

Magnesiacore can be used as a finishing material in wet areas subject to high maintenance from water and abuse damage.

 

Magnesiacore is a fully breathable material being 26% air by volume and microscopically of sponge-like consistency. This can be examined by placing a piece of the material in a bucket of water and watching it float briefly and then see it slowly sink as it becomes fully waterlogged. Magnesiacore will dry out unharmed after getting waterlogged.

 

These important natural properties not only make magnesiacore excellent at holding on to most all types of coatings, paints, fillers and adhesives but in fact allows for constructing walls and roofs that breathe rather than trap moisture. This helps prevent stale and unhealthy air, moulds and other unnatural environments from building up inside building cavities and walls which tends to be the case when building with plastic and metallic sheet materials.

A Variaty of Products for Waterproofing

 

Magnesiacore has partnered with a variety of products that Magnesiacore can provide for interior and exterior coatings that are impervious to liquid water and provide natural waterproofing materials, for wall coating, decorative stucco rendering, as well as waterproofing for walls, horizontal decks and roofing. Some are so resistant they can be used as traffic surface coatings impervious to long standing puddles of water; yet in each case allowing the magnesiacore below it to breathe and release moisture vapours and other gasses.

Magnesiacore as the substrate material together with a variety of selected coatings that weatherproof, waterproof, tint, paint and/or texture to decorate interiors and exteriors while providing the perfect combination for creating building walls and roofs that will breathe naturally with the environment, reducing the tendency for humid and stale conditions that give rise to molds and other unhealthy and uncomfortable conditions indoors.

 

Air and Vapour Transmission Rate (PERMS) can be varied depending on desired characteristics and environmental considerations. The higher the perm rate the more air and vapour can pass through. Plastic Vapour Barriers have perm rates of well under 1 perm and are considered to block vapours and other gasses.

 

For hundreds of years libraries and museums have used magnesia powders inside enclosed bookcases and storage areas to desiccate the air and help prevent the decay of organic artefacts and ancient articles that would have otherwise succumbed the ravages of time from humidity, mould and other environmental factors that cause things to decay and rot.

MAGNESIACORE IS FIRE RESISTANT

 

For Roofing

 

Magnesiacore is used as support board for asphalt shingles where non-combustible construction is required or desired. Asphalt shingles are designed to be nailed in place to plywood or OSB. Magnesiacore allows asphalt shingles to be stapled over a non-combustible material, typically screwing magnesiacore to metal deck or sloped concrete structures, thus allowing shingles to be more quickly stapled on to magnesiacore. Magnesiacore Roofing Slate are also available.

 

 

Options include using magnesiacore screwed to structural metal deck for light weight floor and roof structures that solve many mandated requirements of building codes for non-combustible construction. In wood frame construction, a layer of magnesiacore over the roof sheathing under your shingles will add a measure of life safety protection against fires that can start from outside flaming ambers falling on roofs. Roof fires are a deadly kind of housefire that can collapse a roof onto inhabitants without smoke detectors or any other warnings given inside the house before the cave-in from above.

For Torch-on Roofing

 

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. Magnesiacore can be used with torch applied asphaltic membrane roofing over the top layer. 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.

Non-combustible construction

 

In non-combustible assemblies magnesiacore permits the incorporation of elements into wall systems such as electrical lighting and as well as gas or electic fireplaces.

 

 

Pictured above is a gas fireplace install and a high quality wall. These types of wall finish are difficult to be applied to paperfaced gypsum or other combustible and soft materials. But Magnesiacore makes it easy. The feature wall is that of an Architectural Office. Note the finish in deep blue done without feathered drywall filler for joints and notice no visible imperfection.

MAGNESIACORE IS SOUND RESISTANT

 

Magnesiacore Over Existing Materials

 

Magnesiacore can be applied over existing materials to reduce the cost for demolition, disposal, clean up and related mess. Series of pictures below shows an interior office space refitted with magnesiacore over the walls and floors. Walls show a two layer (larger and smaller panels) system with acoustical goo 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. This not only saves time, money but also the environment by reducing waste for landfills from demolition and disposals. Follow this link to see the Acoustical Test result.

MAGNESIACORE

INSECT/RODENT RESISTANT

 

Magnesiacore Resists Termites, Rodents and other Organisms

 

Anyone working in the hotel/motel industry, campus facility maintenance, hospitals, nursing homes, furniture rental companies, government agencies, etc, will appreciate Magnesiacore.

 

Pesticides can be hazardous to ones health. The best way of not having to deal with pesticides is to keep pests out in the first place. Because mould, mildew, bacteria and fungus cannot live in Magnesiacore, pest stay away. Plus Magnesiacore's hard surface makes it inpenetrable to rodents, ants and other bothersome pests.

Make-over Exterior Pressure Treated Wood Balconies & Decks

 

 

Since 2004 many jurisdictions have banned the use of Arsenic Wood Preservative Treatment in exposed residential construction to reduce the accumulation of arsenic from physical contact with some pressure treated wood. The common green PT wood decks, balconies and railings on residential exteriors (such as the old balcony pictured below) have the ability to be made-over by encapsulating them (reducing physical contact with the arsenic releasing surfaces) with magnesiacore cut into strips and panels giving them a new life as supporting structure for hard flexible concrete-like surface. 5/8" (15mm) grey used cut to 24" wide slabs for the deck floor surface. 1/4" (6mm) grey cut in strips of 1,5/8" and 2" wide to make over 2" x 2" pickets and 1/4" (6mm) grey strips cut 9" wide to cover the wood handrail all fastened with inexpensive 18 gage SS brad nails. Simple, economical and effective solution to make-over a PT wood balcony deck and encapsulate the existing arsenic releasing pressure treated lumber for a do it yourself project or professional installation.

FOR EXTERIOR CLADDING

 

Exterior Panel Finishing Systems

 

Magnesiacore has numerous applications in uses 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 worked with carpentry tools provides simple design options not available in any other all-in-one dry board material. Below is shown a simple wall using 3/8" (9mm) grey, used as base with 1/2" (12mm) white adhered over it to create raised panels; thus creating solid wall panel detailing that combines both (buff) paint and (white) stucco texturing finish... over the same substrate. This would otherwise require different highly skilled trades applying different materials and jointing to create similar effects. The end result is a 20 MpA (3000 PSI) concrete-hard, plaster-like, wall surface that is fireproof and resistant damage from water, moisture, organisms and salts and more resistant to impact damage and cycles of freeze-thaw to reduce maintenance and extend 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 several layers of wet cement plastering to create a hard base when dry. The base coat is made in layers of wet mix, hand applied, trowel on material that eventually create a stucco substrate with uncertain and varying properties and quality depending on the tradesman. A multitude of steps and curing periods, and uncertainty till everything has cured. Using Magnesiacore however, these laborious steps, different materials, and drying downtimes are completely eliminated, and a consistent quality substrate is guaranteed as soon as the board is screwed onto the wall to receive stucco or paint.

 

 

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 stucco goes on directly in a sequential operation without waiting for plaster base coats to dry. Magnesiacore provides an excellent surface for adhesion of stucco. Does not require a great deal of skill to create the uniform base surface; and this also 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.

MAGNESIACORE

USED FOR FLOORING

 

Radiant Heating Floors

 

Magnesiacore used as part of Radiant Floors (or Radiant Wall) Heating Systems allows construction to be done by simple dry boards glued, screwed and or stapled together quickly for perfectly flush surfaces ready to refinish immediately. Added benefits include the ability to more easily access piping by removing boards in the future for repairs or changes which is much more difficult with poured in place concrete. Additionally with magnesiacore laid as a panel finish significant cost saving can accrue.

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.

Substitute in steel construction concrete deck composite floors

 

Eliminates using poured concrete over the metal floor deck in multi storey steel buildings. Apply magnesiacore with screws 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 base surface (without trowel marks from workmanship) and without pouring and refinishing wet concrete slabs. This eliminates the associated high cost, mess and down time of poured in place concrete for your conventional steel structures. This also provides for lighter structures allowing associated structural steel support members to be downsizes by reduced overall structural weight with magnesiacore rather than heavy poured in place or precast concrete to save money and resources. Furthermore, magnesiacore allows the use of sandwich panels for the infill material made with two layers of magnesiacore laminated to rigid insulation to provide insulation between floors of steel structures for both temperature and sound attenuation benefits.

Floor Tiling

 

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 labour can apply the magnesiacore while a tile setter lays the tiles in sequence. Different thickness are available in one millimetre 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)

T&G Jointing

 

This can be applied to floors and walls. 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.

FIRE AND ACOUSTICAL

 

Acoustical

 

For existing rooms, simply applying a layer of magnesiacore (in any thickness) over acoustical goo over existing walls, ceilings and floors provides remarkable acoustical improvement to your enclosed environment. Making rooms quieter, removing echo and reverberations, and letting you hear sounds undistorted. Either by fully wall boarding entire rooms or by applying distinct panels to walls, immediate improvements are seen in the acoustical properties of the room.

 

Whether it is a Recreation Room, Garage, Home Theatre or any other home or other building location where a quiet room is desired or when LOUD rooms need to be silenced to live and work in quieter surroundings. Magnesiacore brings to you the very best acoustic wall and floor system to use in a simple design. Easy to put together without great expense and requires low skill levels to do properly.

 

For professional sound consultants and acoustic trade contractors we offer improved materials and innovations to help create quieter spaces in today's more noisy urban environments.
