The system has a 5-chamber construction, reducing its u-values comfortably below 1.8 Wm²k using only standard hard coat low E glass with air filled units.

This obviously leaves plenty of scope for using Argon gas, soft-coated low-e glass and warm edge spacer bar etc to reduce the figure for allowable emissions even further.

The multi-chambered construction also adds strength and rigidity to the finished product.

T70 is available either pre-gasketed or ungasketed.

The suite of profiles is a complete range, offering the fabricator and thus the domestic customer many options for their fenestration problems.

Many of the AD60 range of ancillaries can also be used in the T70 suite.

The aesthetically pleasing chamfered look of the system makes it easy for the fabricator to achieve a high quality finish to the windows and, its simple design also enables the householder to keep their windows looking like new!

The system is available in White, Mahogany, Mahogany and White, Golden Oak, Golden Oak on White and Rosewood and Rosewood on White.
