Heat and Cold Insulation

Heat and Cold Insulation

The size and type of window will have an effect on the transfer of heat and cold through a window.

Window U-Factor

The U-value measures how well a product prevents heat from escaping. The lower the U-value, the greater a windows resistance to heat flow and the better the insulating value.


Glass Filled Window Glazings

Filling Low-E glass with the inert gas argon will reduce heat loss through the glass by 10 to 15%.  In addition to reducing heat loss, it increases the temperature of the inside surface of the window, improving comfort and reducing condensation.


Sash and Frame Effects on Window Energy Ratings

The sash and frame has an effect on window energy ratings and U-values.By chosing multi-chamber frame designs to reduce conductive heat transfer and reduce heat loss.


Warm-Edge Spacers

Warm-edge spacers can have an effect on window energy ratings. Warm-edge spacers blocks the heat escape path and provides one of the best thermal performances in the industry. In addition warm-edge spacers reduce window condensation, energy costs and noise.


Window Seals

Window seals will also effect the insulating efficiency of the window. Aluminium can hold its strength through extremes of heat and cold. Aluminium windows and doors resist expansion and contraction, they are therefore able to retain their shape in the window and door openings thus ensuring the weather seals that keep your home comfortable will remain unchanged and energy efficient.
