High Performance Windows and Doors:
Our high quality windows and doors can provide a net gain to the energy performance.
We have very low u-values with our standard product manufacturer (Nordan) of 1.2 W/(m².K), however we also offer upgrades to triple glazing and passive standard windows up to 0.7 W/(m².K).
Solar Gain and Shading:
Our designs have large glazing areas which we orientate facing south to maximise solar gain. In some cases, glazing should have solar protection to avoid overheating in the summer. The design of the MVHR system can mitigate this risk with summer bypass extract ventilation.
Smart Ventilation Design:
Although natural ventilation design is possible with our highly air tight construction details and low infiltration rates, we recommend installing a ventilation system. Under building regulations low air test results mean you are forced into mechanical ventilation in any case of which there are several options. The most efficient systems are automated and can act as climate control for your home. Mechanical Ventilation Heat Recovery (MVHR) systems have extract and supply air terminals in all rooms of the house going back to a central unit controlling the air in an efficient and balanced way. This system is designed by our service engineering specialists and has the following advantages over a natural ventilation strategy:

You can add to the energy performance of your home by generating your own electricity to be consumed yourself and also sold back into the national grid. Solar panels, wind turbine and hydro micro-generation are now common and can be cost effective in terms of an investment for a long term income. The feasibility of micro-generation technology will depend on your suitable site specifics and our consulting engineer advice.
