Synseal’s ongoing investment in new extruded profile tooling means that the company’s popular SynerJy 70mm PVC-U system can now provide a tilt and turn window solution with reduced sightlines and greatly improved thermal performance.
In addition to the multi-chambered outer frame which has a slimline height of just 60mm, the 4T1 transom and 4T11 tilt and turn sash can now be used with PTI1 and a new PTI11 plastic thermal reinforcement profiles to give a combined intermediate sash-to-fixed light sightline of just 122mm, which is 20mm reduction on traditional frame constructions using the 4T2 transom and steel reinforcements.
Manufactured from 100% recycled PVC-U, Synseal’s plastic thermal reinforcements offer a number of practical advantages over steel, such as reduced thermal conductivity, less weight, excellent screw fixing retention and lower material cost.
The new PTI11 plastic thermal reinforcement is key to unlocking a new improved level of thermal performance for SynerJy tilt and turn windows. Assuming a 28mm DG specification using Total+/Argon/Float glass with warm edge spacer bar, the new 3rd generation multi-chambered tilt and turn solution will deliver an A-rated WER with a U-value of 1.3 W/m2K, which compares favourably with the equivalent U-value of 1.5 W/m2K delivered by the traditional triple-chambered and steel reinforced approach.
Steve Brown, Synseal’s Products & Customer Service Director comments,
“Tilt and turn windows are a very popular choice in certain regions of the UK including Scotland and our very latest and improved SynerJy solution using multi-chambers and PTRs will certainly look good and keep consumers warm.”
