What are the slip ratings for timber floor coatings

When you place an order with us and you are doing stairs we supply all the documents covering compliance on stairs for our flooring as required under the NZ building code

Semi-gloss = P1

Low sheen = P2

Matt = P3

Oiled = P2

The NZ building code specifies .40+ for stairs which equals the P3 rating for stairs they may become wet.

It pays to check with your architect or builder as to which rating you need

Can you install the flooring?

Yes; We offer competitive installation rates, covered by our master installer warranty. We import a large range of finishing profiles from Europe that go with the flooring we are installing

Can your timber flooring be used with underfloor heating?

Yes our timber & laminate floors are maufactured to work efficiently with heated subfloors and have a no gapping warranty when installed over heated subfloors.

1. System must be capped to a maximum temp of 27 degree C at contact underside of timber flooring

2. System when turned on for first time must be gradually increased to full temperature of 27deg C

3. Concrete sub floor must be coated or covered with an impervious water proof membrane (DPM)

4. The heating of the sub floor will draw trapped moisture to the surface of the concrete so DPM membrane is not optional (our underlay is a 200 micron DPM)

Can timber floors be used in wet areas?

No; timber floors are hygroscopic (take on moisture vapour) so areas that have high amounts of moisture vapour like Ensuite, Bathrooms are not suitable for timber flooring.

Beware; some insurance companies will not accept claims for water damage to timber floors in wet areas  

Why do I need expansion Gaps?

Natural seasonal moisture variations cause a certain amount of movement (expansion and contraction) in natural floors and buildings.
 
 
The required expansion gaps specified by all manufactures and BRANZ for timber, laminate and bamboo flooring are below.
Note: If the sub floor is timber, then the expansion gap is also accounting for its seasonal movement as well
 

Our Laminate Flooring = 5mm - 8mm

Our Timber Flooring = 8mm-10mm

Our Bamboo = 8mm-10mm

Solid 19-21mm Tung & Grove flooring = 12-15mm 

The expansion gaps are hidden by either your skirting boards or specialized floor trims. 

10 or 12mm skirting boards do not provide adequate cover for the perimeter gap.

Expansion gaps manage expansion they do not manage shrinkage in timber floors. 

Why is Unilin floating floor better than glued flooring?

Unilin flooring is unattached to the subfloor which prevents subfloor expansion, contraction or cracking effecting the surface of the flooring.

Unilin flooring (QuickStep or Pergo) are the only timber floors where you get a no gapping warranty on the joint connection between boards . This is due to the flooring being manufactured to be dimensionaly stable during seasonal changes

Glued tung & grove flooring will always reflect subfloor issues in the surface of the flooring and have a tendency to gap between boards over time.

How does the humidity of a room effect timber flooring

The resident humidity of a room (RH) will affect the timber floorings moisture content (MC) causing it to expand or contract.

In modern low moisture homes (RH<45% = MC <10%) high moisture flooring will be under stress and eventually fail due to shrinkage caused by moisture loss drying it out

Moisture loss in solid wood flooring causes cell collapse (cracking and checking) this is why Unilin developed dimensionally stable timber flooring which can handle RH down to 30% = MC 6-7% 

Can I install Uniclic flooring

Below is a YouTube video showing how to install our flooring.

All our floors use the same 3rd generation Uniclic Multifit joint so installation is the same for Timber, Bamboo, Cork, Laminate, LVT and Leather.

Floors only require acclimating for 48 hours on site if within normal moisture range (8-10%) when checked on arrival at site.

The moisture content of the flooring must be checked on arrival at site incase the flooring has taken on moisture during transport

The moisture content of the room (RH) should be checked to see if it is higher than 50%RH or lower than 40%RH. The equilibrium moisture content (EMC) is the room moisture level the floor will adjust to when installed. A high RH 50%+  will mean the floor will expand and a low RH 40%- means the floor will contract away from any fixed point. This is why correct expansion gaps are crucial and expansion gap coverage should be at least 5mm wider than gap 

Expansion gap should not be less than 8mm for HDF core flooring, 10mm for Spruce or Hevea core flooring and 2-3mm for LVT

Our underlay is a damp proof membrane (DPM) with acoustic control up to 19db. So you will not need to apply any other DPM coating to the sub floor as with some other flooring brands

What are Pinch points in flooring

A pinch point is caused by inadequate expansion gaps. Timber or bamboo based flooring will expand in summer due to the warmer air carrying moisture vapour into the home.

This will cause the flooring to expand and press against any fixed perimeter where expansion gaps are not installed. The absence of correct expansion gaps will causing cupping in glued floors and peaking in floating floors. 

What determines the waste factor applied to flooring installs

Waste percentages are applied to flooring installations to ensure there is enough flooring for the installation after cutting the flooring to fit.

Some rooms with a lot of shape require more waste added than rooms that have little shape.

Curves and angles are the biggest creator of waste. 

A waste factor of 15% is common for most solid timber flooring with waste factors of 20% for the less stable timbers.

During acclimatization solid timber planks twist, cup and crack so this wood has to be discarded which accounts for the higher waste percentages required than enginnered timber planks    

How do I maintain your flooring

We carry all the maintenance and repair products for our floors.

General cleaning is by vacuuming or dusting with a micro fiber mop.

Spills can be mopped up and green rated cleaners can be used to clean the floor if needed.

Over saturating hygroscopic timber based flooring during cleaning is not recommended as large amounts of water spread over the floor and left will make the flooring expand to rapidly.

We recommend the BONA floor cleaners and especially their trigger mops, STEAM MOPS CAN ONLY BE USED ON CERAMIC OR PORCELAIN TILED FLOORS! 

What clauses under the building code cover flooring

The clauses in the New Zealand building code that cover flooring are;

E3 for wet areas, commercial and domestic

D1 for stairs and access ways, commercial and domestic

G1 for hygiene, commercial flooring

Domestic flooring should not be used in commercial situations and in some cases would breach the building code under the above clauses

Manufacturers grade their flooring; commercial light or heavy and domestic light or heavy to make sure that domestic rated product isn't used in commercial sites 

For a flooring to be usable in a domestic wet area it must be rated for wet areas by the manufacturer and comply with E3/AS1 of the building code.

Commercial sites require flooring specific to the activity carried out by the business
