Developed in 2004, ULTRA joist has been used by the timber frame and masonry sector extensively and is the leader in medium high rise structural solid joists. ULTRA joist is designed to give a far higher performance in service than any other structural timber currently available on the market. It is approved by both NHBC and Zurich for internal structural applications and is specified extensively for medium rise building due to its unique moisture repellent properties.
ULTRA joist significantly reduces shrinkage and its associated problems, by arriving on site with a moisture content very close to the equilibrium moisture content that the timber will attain once the heating system has been operational for several months.
This unique ULTRA joist treatment not only offers the same 60 year protection as other recognised preservatives, but does so using only a fraction of the water (in some cases only 5%) required by other market leading preservatives. This ensures no swelling or resultant shrinkage caused by the treatment process. Also the built-in water repellent significantly reduces the possibility of moisture ingression regardless of on-site conditions.

It was an easy choice to move to using Glenalmond Timber’s floor joist system. It gives an improved specification for many aspects of the build, including acoustics, ease of installation, lack of bounce in the floor as well of course as cost effectiveness. A great all-round product, it’s a lot more than just a joist and the level of service from Fraser has been a joy. Whenever you deal with people such as that, the business process becomes a pleasure
