** Tubular pipe lagging is ideal for new installations and simply slides onto any pipe up to 21mm in diameter. It requires minimal working space compared to the linear lagging. No special glues required and it forms easily around corners and angles.
*** Depends on diameter of pipe. A 50mm overlap is required.
Woollen pipe lagging prevents hot water losing heat rapidly before it reaches kitchen, bathroom or laundry taps. It also shortens the waiting time before water runs hot at the taps and helps prevent pipes freezing in cold temperatures. To prevent heat loss, wrap the wool pipe lagging material along the whole length of the pipe, or at least the first metre if the rest of the pipe is inaccessible.
Terra Lana wool pipe lagging is available in linear or tubular format. Linear is a rolled length of 75mm width lagging that is spiral wrapped around piping. Tubular is a rolled length sleeve that is slid over pipes before connection.
Pipe lagging made from wool is naturally safer and better for the environment. At the end of the building's life the woolen lagging can be recycled or composted where it breaks down safely and naturally. The lagging contains no harmful substances and requires no protective clothing or masks to install. In a house fire it will not release harmful toxins.
New or retrofit hot water piping in residential and commercial buildings.
Water supply pipe work up to 40mm diameter where frost protection is required.
UPVC pipe work encased in concrete. NB For pipes embedded in concrete or buried underground, Terra Lana PP75 100% Polypropylene must be used.
"As a self employed plumber I believe in offering my customers the best products available, preferably locally made in New Zealand. The Terra Lana range offers both. Using recycled materials and providing Kiwis jobs just makes total sense. I particularly like the pull on pipe insulation that covers 15mm, 20mm and 25mm pipe. It is fast and easy to install and it helps keep my van less cluttered as I don't have to carry 3 different pipe insulation sizes."
