About McWilliam Windsocks

McWilliam Sailmakers has been established since 1971 to be better than the standard.

In 1975 we bought our own plane to overcome delivery difficulties from Ireland to Europe. We found that it was impossible to buy a windsock that would last more than one year, so we made our own from sailmaking quality materials. Other fliers soon began to notice, and orders began to flow. We have grown into one of the largest windsock suppliers in the world.

We pride ourselves on our ability to provide top class service from our initial contact with our customers to our excellent on going service and distribution. We have a team of employees who will take care of all your needs and be happy to answer any queries you might have.

Originally designed for airfield use, the windsocks, swivels and masts are now increasingly sold to industrial and chemical plants. They are crucial for informing emergency services of the ambient wind direction and strength in the event of fire or gas leakage. Many industrial plants in Ireland need a windsock in order to comply with Environmental Protection Agency licensing requirements.


What is a windsock?

Purpose & Usage

A windsock is a conical fabric tube. Windsocks are used as a basic guide to wind direction, speed, and gust factor. Windsocks are used at airports to indicate the direction and strength of the wind to pilots and at industrial/chemical plants where there is a risk of hazardous gas leakage.

Windsock Specification

Windsocks come in all shapes and sizes. The are typically defined by their length, mouth diameter, and tail diameter. The ratio of mouth diameter : tail diameter determines how what wind speed is required to inflate the windsock fully. Typically a 15-knot (28 km/h; 17 mph) wind will fully extend the wind sock.
