The slimline thermally broken aluminium rafter sections have a sleek appearance that brings a stylish ambience and modern finish, while maximising the use of light and space within your home. 

From the outside, the discreet design for rafter external caps and slimline ridge are a world apart from the chunky conventional T-bar caps and ridges used by competitors.

By keeping sight lines low and unobtrusive, the manufacturer ensures even a large glazed roof structure won’t over dominate a plot.

All aluminium exterior coloured profiles are quality finished with powder coat paint, which is guaranteed to last. Dual coloured roofs are also available as the exterior colour can be easily changed to achieve the exterior look you desire.

Units incorporate argon gas, a safe and inert gas that improves insulation, and warm edge spacer bar technology that reduces ‘cold spots’ and condensation, avoiding formation of unsightly mold while improving thermal insulation.

Glass 

As standard, your roof glass will be specified to combine heat reflection and thermal insulation with reduced rainfall and traffic noise.

Low-E and Solar control combination coating, with an argon filled cavity, controls the amount of visible light, UV and heat that passes through the glazed unit. Destructive UV rays are reduced by up to 94%, thus offering protection for furniture and fabrics from sun damage. With self-cleaning technology as standard, your glass will require less maintenance.

Solar control glass

This intelligent glass reflects over 60% of the sun’s solar energy, so your new conservatory won’t become unbearably hot in summer. Solar glare is reduced too, creating a beautifully ambient environment.

Self-cleaning glass

You’ll appreciate the special self-clean coating with a microscopic film which helps daylight and rainwater break-down and wash away dirt and grime.
