Doorwin Collection
High performance doorwin [W+] Collection windows and doors for energy efficient
U-values as low as 0.18 Bth/hr·ft2·F
Doorwin [W+] collection windows last a lifetime. Look around and you will see that in our historic buildings some have been in suit for over 150 years. The way our windows have been designed and engineered ensures the lowest maintenance required and low cost in use over full life cycle.
This makes them the best choice for social housing projects, and new or refurbished council housing stock, where quality is essential for life cycle costing. Even more so in privately financed leased back projects.
Low U values - long life cycle over 60 years
Doorwin’s energy efficient [W+] collection windows can be supplied with a u value of 0.18Bth/hr·ft2·F, (using triple glazing) which achieves the high annual energy consumption targets.
A lower u value high performance window product, with supreme airtightness and some passive solar gain, achieves massive savings elsewhere in the build programmed particularly in the mechanical and engineering and insulation packages, resulting in lower energy consumption figures and more than meeting the targets set.
