5) Thermal reinforcement has now replaced steel and aluminium frame reinforcement, this is again acts to reduce the conduction of cold which leads to heat loss.
Thermal frame reinforcement is far more thermally efficient than metal reinforcement while retaining the strength. u PVC casement windows are designed to be as air-tight as possible.
So you’ve made the decision to insulate your loft, walls and have changed to Solar Power, a choice that will save you money and help to protect the environment by providing free energy and reducing our reliance on fossil fuels. Not only will energy efficient glazing keep you warmer by minimising heat loss, it will also save you money by protecting your investment.
1) Low-iron low-e glass is used on the external glass pane of a double or triple glazed unit, this allows heat waves to pass more freely into the property while still blocking harmful uv radiation and keeping the maximum light to pass through the glass.You’ve insulated your loft, now insulate your windows…Window energy ratings are calculated taking into consideration a range of variables including heat loss, air leakage and solar gain.Contact us for more information on our high quality trade u PVC Windows and Doors.The window energy rating for u PVC windows is calculated on a scale from A-E much like electrical appliances that you may find in your home, the only difference is the way in which the rating is measured.Heat loss is quantified as a u-value and is measured in k W loss per m2 of window area per year, the lower the u-value the more efficient your windows will be.
