Liniar Windows- the proven alternative. 100% lead free with a unique pre-gasketed design.
Launched in March 2008, Liniar is the innovative window system from HL Plastics. Although Liniar is a new window system Managing Director Roger Hartshorn has been highly influential in the industry for many years having founded another leading brand and grown it to become one of the leading window systems companies. He has assembled a team of highly experienced specialists at Liniar to develop and supply an innovative window system that make life easier for fabricators.
Starting with a proven understanding of the problems fabricators face, Liniar designs out problems that add to the cost or difficulty of fabricating, selling or installing PVC-U windows. The result is a window system for the challenges of today, where the means to help fabricators compete more effectively are designed in to the system itself. Unique benefits of Liniar include:

- Pre-gasketed system with a double action bubble gasket which makes corner cleaning easier and minimises the risk of sealed unit breakage.

- Helps fabricators achieve an ‘A’ rating without worry or fuss using a combination of different components.
- Designed, manufactured and supported by a team with over 500 years experience within the window industry.
