About this range & buying advice
From Sheerline Aluminium Doors With A Difference.
Doors with large areas of glass require both thermal efficiency and security. The Sheerline range meets both requirements, offering u-values as low as 1.0 with triple glazing.
Thermally Efficient
With energy costs that fluctuate with little or no notice, planning your home to be thermally efficient has never been more crucial for large glass areas. Heat loss savings can be significant with Thermavic® technology, helping keep you and your home snug and warm.
Double Glazed
U-value W/(m²K)
Thermal transmittance, also known as a U-value, measures the rate of heat transfer. The better-insulated a door is, the lower the U-value will be.
Triple Glazed
U-value W/(m²K)
Available with up to 44mm triple glazing for the ultimate thermal performance. Triple glazing can also provide exceptional acoustic dampening to block out unwanted noise.
Thermavic® Technology
Our innovative thermal technology helps keep you and your home snug and warm while significantly reducing heat loss through large glass areas.
Security For Peace Of Mind
Our patented† corner jointing method creates solid frames, maximising the inherent strength of Sheerline's aluminium construction. A full-depth euro groove also enables us to offer the latest high-security multipoint locking, helping keep you and your home safe and secure. Additional features, such as unique hinge protector,s also help create exceptional levels of security. Prestige's cleverly integrated design also ensures that both door lock cases are fully enclosed, meaning they don't break through into the glazing or beading areas, which could weaken the frame's integrity. So, if you are looking for extra peace of mind as standard, we have you covered.

Traditional threshold option that provides excellent weather sealing and structural integrity for most applications.

Minimised step height for easier access while maintaining weather performance and Part M compliance.
Flush Threshold
Ultra-slim profile for seamless indoor-outdoor transition, perfect for level access and modern aesthetics.
