Underfloor Insulation

Underfloor insulation from Terra Lana is a wool/ polyester laminate specifically designed for the under floor insulation of new and existing suspended floors. Its layered composition means it does not sag once fitted, ensuring no air gap forms between the insulation and the floor (gaps dramatically reduce the effectiveness of the insulation).

This unique construction provides a semi rigid product which has superior insulation properties and is easy to install underfloor. Terra Lana's Wool / polyester laminate is faster to install than closed cell foam insulation because it does not require precise cutting for a perfect friction fit. Bear this in mind when you are calculating the total cost of installation. Variances in joist spacing are easily accommodated, something that is difficult with rigid insulation which has to be cut perfectly.

The firmer layer of polyester on the underside of Terra Lana's insulation provides a tough layer through which to staple the product in place. This layer will not "pinch off", a problem encountered in other underfloor products made from polyester. It also acts to protect the integrity of the product as it is being pushed down the manhole and dragged across the ground and around piles under the house.

Terra Lana wool underfloor insulation is the only under floor insulation in NZ made from a combination of materials that have been specifically designed for underfloor use. Other manufacturers simply take their ceiling or wall product and market it as being adequate for underfloor use. The problem with this is it likely to either sag or be slow to install.
