A few definitions
Headroom
This is the distance between each step and the ceiling. To be comfortable, it must never be less than 2 m at any point on the staircase. It also determines the length of the stairwell opening.
Stair width
It refers to the width of the steps of a staircase, i.e. the width of the passage. It varies according to the type of staircase.
Japanese-style staircase
The Japanese-style staircase is characterised by staggered steps that do not completely overlap. The use of this type of staircase, despite its steep pitch, is therefore made easier by a comfortable step depth and a very instinctive ascent.
Loft staircase
A loft staircase is chosen for its ability to fold away and disappear completely from view
Several types of loft staircase exist:
- telescopic staircases with an accordion-style extension mechanism (generally in aluminium);
- sliding staircases made up of several segments that slide down to the floor (in wood and aluminium);
- folding staircases made up of segments (2 or 3) that unfold to reach the floor.
Going
This is the depth of the step nose-to-nose, measured along the walking line. It is often confused with the tread, which is the total depth of the step. The going is determined using Blondel's formula: 2H + G = 59 to 64, where H represents the step height.
Stringer
a stringer is an inclined member that supports the steps. It is classically located under the ends of the steps; when it is central, it is called a central spine.
Balanced step
The steps begin to turn in the straight flights, allowing wider winders in the turning section.
Radiating step
In the straight flight sections, they remain perpendicular to the stringers; in the turning section, they become radiating.
Stairwell opening
This is the opening created in the floor to allow the staircase to pass through. Its shape varies according to the type of staircase and the minimum headroom required for comfortable use.
A determining factor in the choice of staircase
A few standards
| Step height | between 16 and 21 cm and all steps must be at the same height — the regularity of a staircase is fundamental! |
|---|---|
| Going | between 21 and 32 cm. |
| Headroom | 190 cm minimum. |
| Stair width | greater than 70 cm. |
| Balustrade> | Minimum height of 90 cm for the staircase (measured from the nosing of the step) and minimum 100 cm on a landing. Maximum distance of 11 cm between the support on the staircase and the bottom rail. Vertical balustrade: maximum gap of 11 cm between each vertical bar. Horizontal balustrade:
|
| Landing | Plan for a rest landing when the flight exceeds 25 steps (in some cases, this requires offsetting the lower section of the staircase). Size the landing to the width of the stair width and a minimum length of 1 m. If your staircase is built between two continuous walls, the staircase must be fitted with an independent handrail. |
Questions asked by our customers
| When should the staircase be installed? | On finished floor (if not, remember to shim) On bare wall before finishing (fitting a staircase could damage wall finishes) |
|---|---|
| What staircase width should I allow for if I choose a handrail? | You need to think in terms of total width: handrail + staircase |
| Pre-assembled or kit? | Depending on your DIY skills, choose whether or not to opt for the pre-assembled staircase. Pre-assembled: + ease of installation + time saving for the customer + Less risk of damage at the time of installation Kit: + easier to transport if collected on site - Assembling a staircase requires a good knowledge of DIY |
| Number of packages for the pre-assembled staircase (excluding handrail) | Straight: 1 Quarter-turn: 2 Quarter-turn intermediate: 3 Double quarter-turn intermediate: 3 |
| Taking measurements / key points | Height: WATCH OUT FOR LEVEL It is important to take finished floor-to-floor measurements (or plan for shimming / e.g. for tiles laid after the staircase) Watch out for uneven floors at the bottom / Make sure the starting floor is level Width (partition and stairwell opening) : WARNING: FINISHED STAIRWELL OPENING / PARTITION WIDTH ensure that the customer considers the finished width (e.g.: w=80 cm, but the customer has not anticipated the installation: insulation+plasterboard) Staircase width = allow a 1 cm clearance to facilitate installation |
| Which wood species? | This is above all an aesthetic choice Fir: softwood => softer => "more fragile" Beech and oak => hardwood => "more resistant" |
| Is my staircase making "noise? | Wood is a living material that can cause creaking |
| Where should I store my staircase? | Store your staircase in a dry room for at least 48 hours before installation |
Deliveries, returns and refunds
How does Woodup.fr calculate delivery costs?
Delivery costs are included in the order amount for any order over €600 inc. VAT on metropolitan France territory (excluding overseas departments and territories)...
The delivery deadline corresponds to the dispatch time indicated on the product page, plus the processing and transit time. It is generally between 1 week and 15 days.
Dispatch is the period during which we send the product to our delivery partner. This is not the date on which your order will be delivered.
How does Woodup.fr deliver small parcels?
At Woodup.fr, small parcels are orders packaged in boxes or on pallets. They will be delivered to your home by appointment by our carrier or one of its partners.
Our carrier will contact you when your parcel arrives in your area in order to arrange a delivery date (weekdays only).
If the recipient does not respond, the carrier will identify the best solution to carry out the delivery under the best possible conditions.
In the event of the recipient's absence at an agreed appointment with the carrier, our company may ask the recipient to pay additional delivery charges corresponding to the cost of the second delivery billed by the carrier.
Courier delivery is made to the pavement, at the property boundary or at the entrance to the premises. The carrier will not be obliged to carry a parcel up to a floor.
How does Woodup.fr deliver large parcels?
For very large and very heavy parcels, we use the freight services of our carriers, in order to minimise the handling of these parcels as much as possible.
Delivery is made by appointment, by articulated lorry not equipped with handling equipment (lorry without crane or forklift). As products delivered by freight are bulky and delivery is complex, at least two people capable of unloading will be required to assist the driver.
Delivery takes place on weekdays only and by appointment. In the event of absence at the agreed appointment, our carrier may attend a second time; re-delivery may be charged at €50 inc. VAT. Delivery is made at the property boundary or at the entrance to the premises. Please note, there is no delivery to upper floors. Your home must be accessible by a 38-tonne articulated lorry; if this is not the case, please inform the carrier when arranging the appointment.
Please note: manual unloading of the parcel, piece by piece. Average unloading time is 30 minutes.
