What Is a GRP Composite Door?
Glasgow Reinforced Plastic (GRP) composite doors are an option for the discerning homeowner who demands the finest blend of tradition and technology. Composed of a sturdy, weather-resistant outer frame that encapsulates a high-density foam core, these doors emulate the charm of traditional wooden doors while surpassing them in durability and energy efficiency. They ward off dampness, are resistant to dents and scratches, and boast a remarkable insulation quality that aids in curbing energy bills.
A Wide Selection of Styles and Shades
Each door from Monteith Windows & Doors is a bespoke creation tailored to your preferences. The choices are rich with various colours, from vibrant reds that echo the warmth of your home to reserved blues that resonate with the grandeur of the Scottish skies.
There are countless styles, from classic designs with a timeless appeal to contemporary expressions that make a bold statement. The glass designs are no less spectacular, with options that let you choose your favourite pattern, level of opacity, and light entry. Your door isn’t just a point of entry. It’s a piece of art that should blend seamlessly with the architecture of your entire home.

What are the Benefits of Choosing a GRP Composite Door?
Weather Resistance
The GRP skin makes composite doors highly resistant to the elements, preventing issues like warping, rotting, and fading over time. They can withstand high winds and are not affected by temperature changes.
Security
Typically more secure than standard doors, as they feature reinforced frames and multi-point locking systems as standard. The thick, durable construction makes them resistant to forced entry.
Low Maintenance
Only require minimal maintenance, as the GRP skin does not need regular painting, staining, or treatments to protect it. A simple wipe-down with a damp cloth is usually all that’s required.
Durability
Built to last, the combination of materials used in their construction makes them highly durable and long-lasting.
Energy Efficiency
They have a foam core that provides excellent insulation, helping to reduce heat loss and improve energy efficiency. This can lead to savings on energy bills.
Versatile Styles
Available in a wide range of styles and finishes, allowing you to choose a design that complements the architecture of your home, whether it’s traditional or contemporary.
