Glossary of Terms

This glossary explains hard flooring terms that you may not be familiar with.

Abrasion Rating

An Abrasion Rating is a floor’s level of resistance to wear. Laminate floors have abrasion ratings ranging from AC1 (bedroom) to AC5 (public buildings).

Class Rating

In flooring the class rating represents the degree of performance of a floor when faced with fading; staining; denting; the effects of furniture legs and castors; and other performance indicators.

Crowning

Crowning is where a board has a low dome like shape with a higher middle section and lower edges. It is the reverse of cupping. Crowning can occur if tthere is an uneven level of moisture throughout boards that contain wood. Vinyl planks and sheet do not experience crowning.

Cupping

Cupping is where a board has a shallow cup like shape with a lower middle section and higher edges. This can occur if there is an uneven level of moisture throughout boards that contain wood. Vinyl planks and sheet do not experience cupping.

Embossed in Register

This is the process of creating a texture on the surface of Laminate that matches the grain of the printed design on the layer below. Embossed Godfrey Hirst Laminate follows the grain to provide a dramatic level of realism, especially in timber designs.

Engineered Timber Flooring

Engineered Timber flooring consists of three layers, being, a top layer of hardwood, a core (normally hardwood, plywood or HDF) and a backing layer veneer. These layers are pressed together in opposing directions to create a single board. Engineered Timber floors are designed and manufactured specifically to be used for flooring, making them a very stable alternative to solid timber floors.

Expansion

Wood based floors can enlarge due to moisture or humidity ingress. The expansion of wood based boards (such as timber, bamboo and laminate) is the reason expansion gaps are a critical part of laminate/timber flooring installation. Vinyl flooring products do not experience expansion from moisture or humidity.

Floating Floor

A Floating Floor is a floor that is not nailed or glued to the subfloor. Floating Floors in most cases sit on an underlay. The underlay then sits on the subfloor (in most cases timber or concrete).

Gloss Level

Godfrey Hirst Floors' products feature different surface finishes. The level of gloss indicates how much shine and reflection your floor surface will provide. Different levels of gloss will compliment your space in varying ways.
Products with a matte finish reflect the natural look and feel of timber.  Satin finished boards have a silkier smooth finish suited to polished, formal interiors. A gloss finish provides your space with a striking, polished effect.

Hevea Core

Godfrey Hirst Engineered Timber products have a core stability layer that is made of Hevea. This Hevea core is made from natural latex rubberwood, giving the boards extra stability in this key core layer.

InstaClic

InstaClic™  is a locking system that joins individual boards together with a simple “click”. Most Godfrey Hirst Timber and Laminate boards have this inbuilt system, making installation a breeze.

Janka Rating

When measuring hardness of Timber and Bamboo flooring a Janka rating is used. This test is the industry standard for determining the ability of a particular timber species to withstand denting. The Janka hardness rating is simply the Kilonewtons (KN) of force required to dent the timber, determined by pressing a small ball into it. The higher the number, the harder the floor.

Laminate Flooring

Laminate flooring is made of four layers of materials pressed together to create very hard wearing floors in limitless designs and colours.
These layers are as follows:
• Wear layer – A clear, top layer that provides exceptional resistance to wear, fading and staining.
• Design layer – A high resolution printed paper layer that realistically captures the look of the surface it is imitating. Generally these are timber designs but may also be tile and stone designs.
• Inner core – A layer of High Density Fibreboard (HDF). HDF is pressed wood product that is extremely dense, providing stability for the finished board.
• Backing Layer – A melamine layer providing further stability and also a moisture barrier.

Micro Bevel Edge

Floorboards with a micro-bevelled edged profile have a small diagonal edge that creates a V-shape in the joins between meeting boards.  These bevelled edges outline each board and create an authentic, time worn look.

Profile

When used in flooring, the term “profile” describes the shape of the edges of a board.  Godfrey Hirst floorboards have round, micro-bevel or square edged profiles.

Round Edges

Floorboards with a Round Edged profile provide a rustic look and demonstrate careful craftsmanship.

Square Edge

Floorboards with a Square Edged profile create a sleek and seamless floor.

Subfloor

The Subfloor is the base flooring of your structure and the surface that you wish to install your flooring and underlay over. In most homes this surface is usually wood or concrete.

Underlay

Underlay is padding that is installed between the subfloor and the floorboards.  Flooring underlay provides sound dampening and levels out minor imperfections in the subfloor.

Vinyl Plank Flooring

Vinyl Plank flooring is made of five layers of materials pressed together to create very hard wearing floors in limitless designs and colours.
These layers are as follows:
• Protective Coating – The Polyurethane (PU) coating helps protect against scuffs and reduces maintenance. 
• Wear Layer – A clear, top layer that provides exceptional resistance to wear, fading and staining.
• Design Layer – A high resolution printed PVC layer that realistically captures the look of the surface it is imitating. Generally these are timber designs but may also be tile & stone designs.
• Stabilising Layer/Core Layer – A Vinyl core layer with integrated fibreglass stabilising sheet provides stability, comfort and sound reduction qualities.
• Backing Layer – A vinyl layer that provides further stability.
Vinyl plank comes in a direct stick or floating types. The floating type of Vinyl flooring is available in click together or loose lay varieties.
