What are the slip ratings for timber floor coatings
Slip ratings for our Unilin floor coatings are.
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 a five year installation warranty.
Can your timber flooring be used with underfloor heating?
Yes our timber floors can be used with under floor heating.
There are specific criteria that must be followed
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 DPM)
Can Torlys cork flooring be used in Bathrooms?
Yes, Torlys cork flooring is the only floating cork that can be used in bathrooms.
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 and Laundries are not suitable for timber flooring. Beware; some insurance companies will not accept claims for water damage to timber floors in wet areas
Is undertile heating expensive to run?
Not if the under tile is efficient and our Thermatile is the most efficient system you could install.
A 6.0m2 system will cost approx 18c per hour (based on 24c pkwh)
Why do I need expansion Gaps?
Natural seasonal moisture variations cause a certain amount of movement (expansion and contraction) in natural floors.
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 = 8mm-10mm
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?
By using the Unilin Multifit patented superior joint system the floor is not affected by movement in the sub floor. New concrete sub floors will shrink and crack as they dry effecting glued flooring adversely. Timber sub floors of ply and chipboard can flex with house movement and have seasonal movement affecting anything glued to them. With the Unilin system decoupling the flooring from sub floor expansion and shrinkage, Unilin eliminate gapping, cupping & warping. Gluing or nailing a floor to the sub floor was the only option in the past but as time moved forward and research was undertaken to improve the performance of timber floors in modern dry homes. It was realized very quickly that some subfloors like concrete were not completely suitable for gluing timber flooring too without a large amount of cost in moisture and crack protection. Decoupled the flooring solves all the potential problems with gluing to concrete and the seasonal movement in timber based sub floors. The underlay we use under our flooring has a damp proof membrane so the cost of having a timber floor over a concrete subfloor is reduced massively. When a floor is floated over a superior underlay you can reduce sound transmission and increase warmth.
How does the humidity of a room effect timber flooring
The resident humidity of a room (RH) will affect timber flooring by causing it to expand or contract. Our floors are manufactured to moisture content (MC)of 6-8% Bamboo, Laminate and 8-10% Timber. When flooring is installed it will try to stabilize with the RH of the room. This is called the (EMC) equilibrium moisture content and is the reason high moisture flooring must be filet stacked on site for many days so it can reach EMC and during this period it may cup & twist slightly. This is why solid floors require a 5-7mm sand-able wear layer as the wear layer will be reduced by sanding (2-3mm) to flatten the boards before top coats are applied. Our flooring doesn't require this type of acclimatization on site as our MC is close to the EMC of most homes 9-10% at a RH of 45% - 55%. Since our floors do not cup or twist and are prefinished there is no reduction in our wear layers. Warm air collects up moisture as it travels over the land, mountains and water. So water side properties will have more moisture in the air around their homes than properties on the open plains . Hygroscopic flooring will receive this moisture vapour as warm outside air enters cooler inside rooms and it will expand. In winter we close our homes off from the outside and heat the inside so the air will not release moisture vapour it will collect it causing hygroscopic flooring to release moisture and contract
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
