kingspan TW50 cavity insulation

Kingspan TW50 Cavity Insulation

Kingspan Insulation Therma range includes the Kingspan TW50 partial fill cavity wall insulation. This insulation board is designed to be built in between brick and block cavity walls. It is a high performance rigid PIR thermal insulation core board and has a low emissivity foil facing on both sides.

This type of Kingspan PIR foam insulation board can often meet the same thermal values of that of fibreglass but at half the thickness.

Kingspan TW50 can have a thermal conductivity as low as 0.022W/m K. This is dependent on the other materials used in the overall construction. Using this product enables the ability to maintain a partially clear cavity. Notably this style of cavity wall construction is widely acclaimed to be the best way to build.

TW50 board resists any potential moisture penetration. Kingspan cavity insulation board meets the national house building councils technical requirements when leaving a 50 mm clear cavity. It is easy to handle, and safe being a non deleterious material meaning it is non damaging to both health and the environment.

Please see the technical document below for further information.

As a small building company we find that BMD will equal or beat our trade depot plus we get free delivery too !!, Also we can get everything in one order and being able to talk to an actual person rather than clicking on a website means we get the service we want. saves time and money whats not to like ? :-)
