New sustainable builds will benefit from the latest innovation from aluminium glazing systems company Reynaers – MasterLine.

This unique window and door solution is being used in a number of new residential and commercial builds, combining maximum daylight and three insulation levels that can be tailored to individual projects. The system has excellent energy efficiency credentials, a high level of security, as well as enormous design freedom, thanks to the impressive amounts of variants and four frame styles.

Extensive development and rigorous testing have resulted in a product that sets a new benchmark in terms of quality, performance and aesthetic appeal. Created with architects in mind, MasterLine was developed entirely from scratch and is a brand new platform for the next generation of windows and doors.

The system offers class-leading thermal performance and weather resistance boasting Uf values for the doors as low as 0.87 W/m2K, and for the windows a Uf value as low as 1.0 W/m2K. With 900Pa water tightness, and class 4 wind resistance, MasterLine offers complete protection from the elements.

Stronger accessory grooves make vent weights up to 200kg and vent heights up to 2.8m possible. This means that windows and doors are safe and robust, without compromising on the industry-leading maximum frame sizes.
