Engineered Wood

Pre-finished Strips of Engineered 2-layered Natural Wood Floors with high quality & long life time.


Industrial Composition of the product

Engineerd wood is composed of two layers plus a coating layer.

⦁ The upper layer from hard African or European wood with 2 to 10mm thickness.

⦁ The button layer from plywood (brich )russin mae with 8 to 12 mm thickness.

Coating:

5 Layers of European U.V Acrylic coating material with high resistance towards friction & corrosion

Glue used in Production:

European PVA-D3 Glue is used in the production phases complying with all the European Industrial & environmental standards .

Technical Specs

Strips size in mm

Length Width Thickness

Installation Methods:

Viplex can be applied to any Flat surface (Tiles - Ceramic - Wood - Flat Surfaced Concrete)


Floating System :

Where the strips are directly installed over a layer of poly ethylene with 2 mm thickness while using the PVA-D3 glue on the boards' tongues. This method is preferred for all the other methods.

Viro Floor Method:

Since our product is composed of natural wood, It could be nailed down on thin softwood strips of 8 mm thickness with 2 layers of poly ethylene above and under the strips to protect those strips & the boards against humidity. This method is preferred for its good sound resistance plus its humidity resistance

Glue down method :

Where the strips are directly glued to any flat floor using polymer-based glues made specially to glue wooden floors to any flat surface.

Why Engineered Flooring



Engineered flooring is made up of a core of softwood or plywood and a top layer of hardwood that is glued on the top surface of the core and is available in almost any hardwood species. The product thus has the natural characteristics of the selected wood species as opposed to a photographic layer. The "engineered" flooring has been designed to provide greater stability, particularly where moisture or heat pose problems for solid hardwood flooring.    

The instability of solid hardwood is usually moisture or heat related. Under adverse conditions, solid hardwood can warp, cup, swell or split apart. Engineered flooring overcomes these problems by constructing a multiple-ply plank which counteracts twisting and remains flat and intact. This makes engineered flooring a better choice for installation over radiant heat sources, over concrete whether it's below grade or above, and in rainy climates.

Not at all. The top hardwood layer is the same genuine hardwood you have in solid hardwood flooring. 

The hardwood top layer can typically be 3.5mm to 6 mm or more in thickness. A quality hardwood top layer will provide many years of wear. 

It depends upon the thickness of your hardwood layer but the fact is that 95 % of hardwood surfaces are never refinished. With the high quality finishes that are offered and the extensive process that refinishing a floor entails, damaged areas are often removed professionally

If sanding is desired, typically, the professional sanding procedure removes 0.8 mm . Thus if your floor has a 4mm layer you can sand the floor up to 5 times .

Hardwood veneers have the same surface appearances as solid hardwood flooring because they're both natural hardwoods. Different appearances result from the different ways the hardwood is sawn. The different sawing methods are: i) Flat Sawn or Plain Sawn, ii) Rotary Cut, and iii) Sliced Cut.

Flat Sawn (also referred to as plain sawn) - can be flat grain (which has a cathedral or gothic effect) or vertical grain (which has a radial or edge grain effect).

Rotary Cut - method of cutting wood (also referred to as peeling) in which the hardwood layer is peeled off the log using large wood lathes. This peeling method shows dramatic, wilder graining.

Sliced Cut - method of cutting wood in which the hardwood layer is sawn like regular lumber. This shows method finer graining.
