Joinery Developments Ltd specialises in door and window hardware and hinges. We supply primarily to the Aluminum Fabricating Industry and Interior Partition Industry.
Under the name "Easy Air", we also specialise in passive (trickle) ventilation, primarily for residential homes, however our window vents are also suitable for many other building types where there is a need to improve indoor air quality and reduce condensation and mould.
EasyAir trickle vents provide a gentle flow of natural air that helps to stop condensation on your windows and helps to promote a healthy home environment

EasyAir vents can eliminate mould and condensation the effective, natural way, with zero electricity usage.
EasyAir ventilators can be built-in to aluminium or timber joinery to let fresh air in - and moisture and pollutant-laden air out.
The flow of outside air can be altered - or cut off altogether - simply by adjusting the durable plastic slider.
EasyAir ventilators work at the touch of a finger. An optional cord control allows you to adjust the air flow in hard to reach places.
EasyAir vents include a sturdy insect screen and a unique, fully tested outer shield to ensure pests and the elements are kept out while letting the fresh air in.
EasyAir vents provide a secure option for passive ventilation. They will continue to let in fresh air even when all of the doors and windows are safely locked up, and without draining electricity. They are ideal for batches, holiday homes, school buildings and other places that are usually shut up for long periods of time.

EasyAir vents are crafted from long-lasting aluminium and powdercoated or anodised in a range of fashion colours. They can also come in dual colour if required.
EasyAir vents are a high specification vent designed for NZ conditions and complies with NZ 421 1 Standard for windows. Its air leakage factor complies with level 2 of the above standard so it can therefore be used commercially in air conditioned buildings. It can be cut to any size within the constraints of appearance (too small) and wind loading (too long).
When specified correctly, EasyAir vents will meet or exceed the minimum requirements for background ventilation.
EasyAir passive vents don't require any major renovation work when fitted to existing windows. A qualified tradesperson can fit the ventilator panels to any existing aluminium or wooden joinery with minimal fuss.
The average cost is around $40 to $50 per vent (priced according to length), plus a per-vent installation cost of around $50. A typical 3 bedroom home requires approximately 8 - 10 trickle vents.
