Property:Development:Construction:Siding

Summary

* patterns:

clapboard: the simplest horizontal siding, with simple boards overlay-ed over each other.
lap patterns: allow for overlapping boards, using rabbets on alternative sides, a thining of the bottom board so that it fits into an upper board's rabbet.
- dutch lap: a more modern, flush, look than clapboard. Flat with an angle at its top so that it can slide under the board above it.

* Board and Batten: boards whose vertical seams are covered with battens (thin strips of wood). Board can be plywood (although there's a class action in NZ going no against this approach that failed pretty miserably). * Wood strip siding: strips beside each other (as oppossed to lapped). Can be tongue and grooved. * Stucco: least expensive material, but requires more labour to attach it to foam or fibre cement boards. * Yakisuga-ita: flame-thrown wooden siding¹⁾. * soffit: located on the span beneath the rafter tails. Along with fascias, used to keep out elements, birds, and insects - and hide ventilation. * fascia: located on the exposed horizontal band at the end of the rafters.

“Metal/steel siding usually costs about $20 more than vinyl siding per every hundred square foot.”²⁾ (but that's not really that much) while more resistant (than PVC) to warping, thermal expansion etc.
Fibre boards contain cancer-causing agents (silica)³⁾.
Membrane:
- Advantages:
  - One of the lowest cost ceilings.
  - Designed for flat roofs.
  - Due to ease of manipulation and fixing, can be a DIY product⁴⁾.
    - Considerations:

      Black Absorbs heat (not a bad thing).
    - Disadvantages:
      
      Can easily be punctured (eg: during delivery, or later by falling branch…although Oriental Bay has a couple, right beside trees…)
      
      Hard to challenging to find location of any leak⁵⁾.
    * PVC:
- Advantages:
  - Colour is throughout, therefore does not repainting.
- Considerations:
  - Thermal expansion, UV damage, is higher than metal sidings etc.
  - Cost:
- Disadvantages:
  - Not suitable for repainting to a different colour.
Metal/Aluminum:
- Advantages:
- Considerations:
  - Cost: $35-$45/sq.m (US) ⁶⁾
- Disadvantages:
  - Oxydizes to a white chalky finish.
Metal/Steel:
- Advantages:
- Considerations:
  - Cost: About a 1/3 more than aluminum siding.
    - (US) $40-$80/sq.m ⁷⁾
  - May not be best for high-wind zones⁸⁾.
  - Heavier than aluminum, needs a couple of people to manage it correctly, so not exactly a DIY product.
  - Needs repainting every couple of years (but so do most things).
  - More expensive than PVC.
Hardboard/Pressboard/Masonite:
- Advantages:
  - …was cheaper than vinyl or anything else⁹⁾.
- Considerations:
  - …
- Disadvantages:
  - Doesn't last and can be a ticking bomb in humid environments¹⁰⁾¹¹⁾.
Hardieboard/Fiber-Concrete Board:
- Advantages:
  - Lasts forever (or 50 years). So if you can afford it it lasts longer than other products.
  - Good in wind¹²⁾.
- Considerations:
  - Really heavy, slowing installation, rising cost.
  - Needs to be painted every 15 years or so ¹³⁾.
  - Costs vary wildly between products so hard to be firm on final cost.
  - Cost: $100/m2¹⁴⁾. Not cheap up front.
- Disadvantages:
  - Heavy and needs care to not damage panels. This slows installation and causes a need for experienced crews. Not a DIY material.
  - Needs experienced crew to handle it correctly¹⁵⁾.
  - Probably not appropriate for budget homes.
Zinc:
- Advantages:
  - Lasts a long time.
- Considerations:
  - Not as expensive as copper, but far more than steel.
  - Cost: (US) $150-$250/m2 ¹⁶⁾
- Disadvantages:
Copper Siding:
- Advantages:
  - Very lightweight, so easier to work with.
  - Never corrodes.
- Cost: (US): 250-350/m2 ¹⁷⁾
- Cost: $70-$90/sq.m. (US)¹⁸⁾
- Disadvantages:
  - Cannot afford in this lifetime.

It's very easy to get US costings from the web. NZ is a totally different story.

Metalcraft told me the following:
- Corrugated:
  - Roofs: $65/m2 installed
  - Walls: $120/m2 installed, of which $30-35 is the material, and $85/m2 is the labour (dealing with multiple openings and flashing).
- Obviously things get more expensive from there for more modern profiles (but most of the cost is labour…)
