The Composite Door Range

“You really can create a bespoke composite door that is unique to your home.”

Enhanced Security

A Infinity HI 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.

Stunning Aesthetics

The woodgrain finish on an Infinity Home Improvements GRP composite door is inspired by authentic oak, offering both exceptional appearance and performance unique to our doors.

With a wide selection of colours, styles, and glass options, you can create a bespoke door. We ensure perfect colour, woodgrain, and moulding consistency, guaranteeing a flawless finish.

All our glass designs are crafted to complement the door styles and colours, featuring triple glazing for enhanced security and energy efficiency.

Our Glass Re-Enforced Plastic (GRP) composite door offers superior thermal efficiency. Independently tested, our 44.5mm Premium composite door outperforms both a 48mm solid timber core and a 44mm timber-paneled door, proving to be over 17% more thermally efficient.
