The UPVC Door Range

Enhanced Security

A Infinity Home Improvements GRP composite door offers enhanced security thanks to its rigid polymer sub-frame, high density insulated core and high impact resistant GRP skin.

The door leaf and glazing system are major components when part of a door set and have a proven ability to achieve PAS24:2016, industry’s enhanced security standard, a prerequisite in attaining certification to Secured by Design a police initiative to protect against unlawful intrusion.

A welcoming home starts by choosing the right door. Your new UPVC door needs to enhance your home’s appearance and suit your lifestyle, coping with all the rough and tumble of a family life.

Stunning Aesthetics

The woodgrain finish on a Infinity Home Improvements GRP composite door is developed from oak tree wood grain, creating a beautifully authentic appearance and superior performance that is only available on a Infinity Home Improvements door.

Our range of colours, styles and glass options will make your door truly unique and by ensuring that we perfectly match the colour, wood grain and moulding on the glazing cassettes, you can guarantee a flawless finish.

All of our glass designs  complement our door styles and colours and are triple glazed for extra security and energy efficiency.

Ultimate Energy Efficiency

When it comes to thermally efficient doors, our Glass Re-Enforced Plastic (GRP) composite door is the best choice you can make.

Our Premium composite door (44.5mm) has been independently tested against a solid timber core composite door (48mm) and a timber paneled door (44mm). The results prove the Infinity Home Improvements composite door is more than 17%+ more thermally efficient than both of these alternative doors.
