Investing in the ‘Ultimate Closed System®

An investment in the ‘Ultimate Closed System®’ Roof, Walls and Panels offers a minimum lifespan of over 100 years – homeowners can live life happily in an energy efficient home, reducing annual heating and running costs, drastically. Hence, allowing homeowners to spend money on more important things.


Benefits of the ‘Ultimate Closed System®’ stem far beyond the standard benefits of any Timber Frame structure in terms of self-performance. It gives homeowners a future-proof home that is draught free with high air quality conditions.

U Values results from the ‘Ultimate Closed System®'

Through internally and using an independent third party, QTF Services have determined the uvalue of the Ultimate Clsoed System insulation as 0.15W/m2K. The better-insulated the Timber Frame structure, the lower the U-value will be. Workmanship and installation standards can strongly affect the thermal transmittance. If less insulation or fitted poorly, with gaps and cold bridges, then the thermal transmittance can be considerably higher than desired. Thermal transmittance takes heat loss due to conduction, convection and radiation into account.


QTF ‘Ultimate Closed System®’is a closed panel Timber Frame solution, designed to eliminate the risks of any gaps and closed bridges. It is also professionally insulated and overall ensuring maximum heat retention and active automatic cooling of its environment, driven by natural result of the timber.
