Features of the laminate
The laminate is composed of a very durable protective film, a decorative sheet imitating wood (overlay), a panel from resin and wood fiber (HDF) and a counterbalance that helps to maintain the stability of the product. This product is simple to lay and is a good compromise to get wood-effect floor at a low cost. Today, laminate floors are gradually gaining market share in the flooring segment.
These materials are affixed via floating intallation without having to apply the material onto rough base flooring. Furthermore, this laying system gives the possibility of superimposing this type of material in existing floors without the need for further simplifications and disposal of the old surface.
Intrinsic feature of these materials is their hygroscopicity, or the ability of a substance to readily absorb the water molecules present in the environment in the form of moisture. In fact, the wooden part in a fibrous state inside the HDF panel is a material in constant motion that changes its volume according to changes in humidity. This problem of dimensional stability is reflected in a phenomenon of micro-movements of the flooring, called expansion, which manifests itself more along the short side of the board, where it is usually preferable to lay the planks in such a way that their long side corresponds to that of the premises.
The laying of the laminate
The general deciding criterion is to respect a space the perimeter of the fixed parts by at least 10 mm, which it will subsequently be covered by a skirting board. The upper sides 8-10 ml long are interrupted by a joint at least 30/40 mm wide, subsequently covered by a coordinated profile called expansion joint for floating floors.
Several adjoining premises (rooms, hallways, kitchens, living rooms) are compulsorily interrupted near the doors to allow for expansion joints. This will prevent opposing expansion between different environments that could negatively affect the normal expansion of the floor which, acting in counter motion, would cause either disarmament across a stave or even the classic “wave effect” between the slats.
The ranges of product Unisystem® and Unisystem® Plus created by Profilpas group a series of expansion joints in order to resolve the problems of floating floors.
Unisystem® and Unisystem® Plus are two professional systems for the floating laying of wood and laminate floors which allow the necessary expansion. Both systems comprise a base profile in natural aluminum and top profiles with different functions:
- junction profiles of the same level
- profiles for level differences, which allow the compensation of thickness between non-coplanar floors
- terminal profiles, which allow you to delimit parquet or laminated floors
- perimeter profiles, which allow you to connect the floor to the lining
- step nosing profiles for stairs
Unisystem® Plus, an evolution of Unisystem®, differs from the former through the use of special teflon anchors that allow a quicker laying of the top profile and its eventual removal in the case of modification and / or maintenance of the floor. Both systems are characterised by easy installation, reduced thickness of the top profile, dimensional stability, use for floors of thickness from 6.5 to 22.6 (Unisystem® Plus) and from 6.5 to 15 mm (Unisystem®), and the availability of various decorative finishes (4 anodised finishes, 54 wooden decors).
