Services provided

Red brick buildings flank a street under a cloudy sky, with parked cars and sparse greenery, creating an urban residential scene.

Achieving optimal performance

The project consisted of replacing windows while ensuring that the highest energy efficiency, security and ventilation standards we all met. These included:

– Design wind load: 2000 Pa
– U-value maximum of 1.4 W/m²K or better
– Water tightness of 200 Pa (Class 5A)
– Tested to Enhanced Security PAS24(2016)
– Build in concealed trickle vents of Free Area 4511 (mm²)

The project

The overall window replacement project included the following:

The new traditional Box Sash windows installed were matched with the original style and proportions, shape, glazing bar size and placement, overall glazing patterns, opening methods and materials and finishes.

All ground floor and easily accessible sash windows and doors were supplied as PAS 24: 2016 certified.

To meet energy efficiency standards, it was ensured that all replacement windows had a U-value of 1.4 calculated by the standards of EN ISO 10077-1:2006. The lower the U-value the lower the energy loss (typically, new sash windows should achieve a U-value of 1.6 W/m2⋅K or lower).

Lastly, ventilation was provided via controllable Titon XS16 4600EA trickle ventilators, dependent on the width of the frame.
