Timber Frame Insulation

Timber Frame Insulation and Timber Frame Construction

Construction using timber framing has several advantages;

  1. Walls are thinner, yet maintain quality thermal performance;
  2. A tighter sealed construction is enabled;
  3. With a lower moisture content included in the construction than in traditional masonry techniques, the drying time drops, which significantly lowers any risk of condensation;
  4. Extensive facing options can be considered including brick, boarding, tile/slate hanging and even rendered block.

Ballytherm wall insulation can be implemented in the construction of timber frame insulation buildings. It’s an optimal choice for new projects as well as extensions and improvements.

Ballytherm Insulation‘s unique attributes make it an excellent fit for this sort of application. With its low thermal conductivity, the thickness of space used for the necessary insulation is reduced, creating an ultra-efficient use of available space.

It’s possible to use one of two methods in order to insulate timber framed walls with Ballytherm insulation:

  1. Using standard 140mm thick studs, it’s possible to attain U-values as low as 0.22/m2K. This is achieved with Ballytherm Insulation being fixed in between the studs, followed by a plasterboard facing.
  2. Wall insulation that is tightly fitted between the studs, followed by a layer of Ballytherm Insulation across the stud face, then attached directly to the studs or held in place with battens, can achieve U-values as minimal as 0.18W/m2K. When using battens in the installation, the reflective surface of the Ballytherm boards can cut radiation heat loss through air spaces. This greatly enhances the thermal function of the wall.

When determining appropriate dimensions of Ballytherm thermal insulator needed in order to meet industry regulations, use Table 13 provided here.
