Services

Double Glazing

Our double glazing solutions use Low-E glass and 16mm insulating gaps to reduce energy bills by up to 160 annually. Pilkington K and Guardian ClimaGuard glass options provide superior thermal efficiency, noise reduction, and security with advanced locking systems. Each installation includes a 10-year guarantee, Kitemarked units, and maintenance-free uPVC frames that resist warping and weather damage.

GRP Composite Doors

Manufactured with thermoset GRP skins and CFC-free polyurethane cores, our composite doors offer nine times better thermal efficiency than timber. Impact-resistant surfaces mimic authentic wood grain while resisting temperature changes. Features include multi-point locking systems, anti-splinter construction, and a 10-year warranty, combining security with aesthetic appeal through customizable RAL colour finishes and decorative panel options.

Conservatory Roofs

Global Conservatory Roofs feature aluminium/PVC-U construction tested to withstand 250kph winds and 2.7m snow loads. The Tie Bolt locking mechanism enhances structural integrity while concealed gaskets create seamless aesthetics. Available in Victorian, Georgian, and Gabel designs with aluminium top caps, these roofs include watertight seals and 10-year guarantees for durable, energy-efficient extensions.

Aluminium Windows

Precision-engineered aluminium windows combine slim profiles with thermal efficiency through polyamide breaks and double-glazed units. Available in custom RAL colours, they feature secure locking systems and chambered profiles for noise reduction. Ideal for contemporary properties, these low-maintenance windows resist corrosion and come with a 10-year installation warranty.

Bi-Fold Doors

Our bi-fold doors create seamless indoor-outdoor transitions with multi-panel configurations and 20mm sightlines. Triple-track options allow wider panels for maximum light transmission while maintaining security through shoot-bolt locking systems. Thermal breaks and double glazing ensure energy efficiency, complemented by a 10-year guarantee on both hardware and installation.

I want to thank all the hard work from everyone who worked on our house from hi spec including Bal, Harvinder, Gurbaj, Avtar, Kulwant and Satveer. They went above and beyond fitting our windows in, listened to our concerns and did a fabulous job on it
Our house looks brand new, lovely quality and brilliant service!

Had all windows and bi-fold doors replaced by Hi-spec - see the pictures. Brilliant service from start to finish - Nav provided personal service advising us of our options, and we went for casement windows for the front and standard for the back and bi-fold doors. Fitting by Sandeep and Prince was very high quality - good attention to detail. Would recommend this company....locally manufactured as well so even better to support local and UK companies.

High Spec updated our old double glazed windows with new, replaced a door with a window and replaced a window with a door. The finish was great and the brickwork outside looks lovely. The men that came to fit the windows and doors were professional and tidy and pricing was reasonable and competitive. We will be using the company again when we replace windows at the front of our house.
