Characteristics of LVT flooring
The acronym for Luxury Vinyl Tile, LVT flooring, is the result of further technological development of PVC tiles. It comes in a variety of surface coatings, including wood-effect, concrete and flagstones all with a highly authentic look and feel combined with all the proven benefits of a vinyl floor.
Technically, this flooring is made by laminating multiple layers of vinyl sheets in a heat and pressure process, very similar to that used in the production of laminated floors. Pressure and heat cause the various layers to fuse into one. In the fusion process, a surface decorative layer is also added using digital technology and then finally a wear-resistant PVC layer.
The fundamental technical particularities of this product are its reduced thickness (usually between 4.5 and 5.5 mm), its enhanced wear resistance, stain resistance and its impermeability. Designed for use on floating floors, the coupling system between the staves is very similar to the click-together systems used in laying laminate flooring.
Thanks to its reduced thickness and other characteristics, this product is well suited for use in refurbishments of housing and commercial/service sector premises.
In the creation of these products, it is now common use to add one or two layers of glass fibre between the different sheets of vinyl. This stabilises the PVC panel and prevents shrinking or stretching. In fact, these products, of 100% vinyl material of various types, fluctuate in volume according environmental temperature variations.
Expansion joints avoid risk of dimensional instability
The problem of dimensional instability is reflected in micro-movements of the flooring called “dilation”. These are easily avoided thanks to a series of features that we will now go on to list.
The general rule is to leave a gap between the flooring edge and the perimeter wall of at least 10 mm. This gap will subsequently be covered by skirting board. Lengths in excess of 8-10 m need to be interrupted with one joint of at least 30/40 mm which is then covered by a matching seal called an expansion joint for floating floors.
Where there are several adjoining rooms (rooms, hallways, kitchens, living rooms), flooring sections must be joined near the doors by expansion joints. This prevents conflict between flooring expansion in different adjoining environments negatively affecting the normal expansion of the floor. It acts as a counterforce, preventing slats from pushing against each other so preventing the flooring from undulating.
The Profix range from Profilpas
The Profix range created by Profilpas contains a series of expansion joints geared to avoiding problems with LVT floating floors. Profix is, in fact, a professional system for laying LVT floating floors, which allows for, and compensates for, necessary expansion.
The system consists of a basic floor edge seal in natural aluminum and top seals with different functions:
- joining seals for flooring at the same level
- joining seals for floors of different levels that compensate for thickness differences
- Edging seals that allow you to delineate a neat finishing edge to a section of LVT floor
The system is characterised by easy installation, reduced thickness of top floor seals, dimensional stability, usability for floors of thickness from 4 to 6 mm, availability in various decorative finishes (1 anodised finish and soon 14 decorative wood-effect finishes).
