Energy Efficiency

In today’s climate we need to look at the performance requirements of many aspects of our home that effect its overall energy efficiency and reducing the amount of heat loss through windows and doors is imperative.

Using Timber for energy efficiency

At Whetstone Windows and Doors we only manufacture our products with timber. As well as being asthetically pleasing, Timber is favoured in residential applications from an energy efficiency standpoint. Timber-framed windows perform extremely well due to its excellent thermal properties. In fact, timber windows rate better than aluminium in reducing winter heat loss.


Glazing Options

Double Glazing or Laminated Single glazing

When deciding on energy efficient doors and windows, we offer the choice of double glazing orComfortPlus™ laminated single glazing.
ThermoTech™ is a range of sealed insulating glass units that offer improved insulation. This double Glazing comprises of two panes of glass with a hermetically sealed airspace between. So by reducing the air-to-air heat transfer, it provides a more stable and controllable internal environment which then reduces heating and cooling costs.

Where double glazing is not an option, we recommend using ComfortPlus™, a laminated safety glass with a unique solar control coating. It economically manages the heat of summer and the cold of winter. It incorporates a solar control component that in summer reduces the sun’s heating, glare and UV fading of interior furnishings. In winter, the ComfortPlus coating provides thermal insulation and reduces heat loss through the glass by over 30%
