Tilt & Turn Windows

T&K’s Tilt before turn PVCU windows utilise large glass panels to create a flood lit environment that brightens up any home. They provide an ideal solution where larger glass areas are required with a maximum height and width of 1450 x 2300mm. The windows are easy to clean, thanks to the innovative design.

They allow for your windows to be opened wide and cleaned from the inside of your home. Not only do these unique features make for a cleaner and brighter result, they also make maintaining your windows safer too.

All of T&K T/T designs are manufactured using the 70mm optima system and amazingly hold the same u-values as all of our classic and flush windows. T&K can offer the Tilt before Turn design in both the classic style and the Flush casement style if requested.

how we try to help the environment

What is Recycled Composite Material (RCM)?

At T&K, we use Profile 22 as our PVC-U window and door systems manufacturer.

Profile 22 uses RCM to minimise their impact on the environment, meaning all of our PVC-U windows and doors are more environmentally friendly than our competitors.

Recycled Composite Material (RCM) is a reinforcement for PVC-U windows and doors manufactured from recycled waste PVC-U.

  Supplied as a substitute to either steel or aluminium sections, RCM is a cost effective alternative that offers superb benefits, while being fully sustainable. Developed as part of our proactive stance to increase the sustainable credentials of our product range, RCM closes loop to the recycling process, offers better thermal efficiency and has a minimum life cycle of 35 years.


  • Unique and patent pending RCM reinforcement from Profile 22.
  • 100% recycled composite material reinforcement – fully and easily recyclable.
  • Increases thermal efficiency – achieves a higher energy rating than comparative windows/doors with steel or aluminium reinforcement.
  • More than 35 years’ life expectancy.
  • It doesn’t corrode or rust.
  • RCM has a screw pull out value greater than steel.
  • The price of RCM is stable.
  • 20-30% increase in corner weld strength.
  • User friendly, easy to cut and clean, lighter than steel - making it easier
    and safer to handle.
  • RCM makes windows easier to install as it is lighter and windows can be
    carried more easily.
