A Rated Sash Windows Using Planitherm Total + Insulated Glass (As Seen on TV)

Over a quarter of all domestic heat loss escapes through windows and doors and with spiralling energy bills this can add up to a lot of wasted money. The single most important factor, relating to the energy efficiency of a window, is the glass.

By combining SGG PLANITHERM TOTAL+ with other specialist glass products available, a multitude of high performance, multi-functional double glazing solutions can be achieved.

Solar Control Glazing

The SGG COOL-LITE family presents an extensive range of solar control solutions, designed to reduce solar heat gain, thereby reducing reliance on ventilation and air conditioning systems.

Low-maintenance Glazing

SGG BIOCLEAN can be combined with SGG PLANITHERM TOTAL+ to add effective self-cleaning properties to a double glazed unit. This product combination offers a significantly more neutral and less reflective solution compared to equivalent products currently available on the market.

Acoustic Glazing

SGG STADIP SILENCE is an acoustic PVB laminated glass, which noticeably reduces noise while also offering the same safety and security characteristics as laminated glass.

Increasing Solar Gain to Increase Energy Rating

Window Energy Ratings Combining SGG PLANITHERM TOTAL+ with SGG DIAMANT low-iron glass in the outer pane can improve the energy index of a given window by further increasing solar gain.

Super Spacer

To enhance the thermal efficiency and life of our windows we fit our double glazed units with low conductivity Super Spacer. This replaces the traditional metal bar and helps prevent or eliminate condensation round the edge of the sealed unit.The spacer is manufactured from a high-quality silicon that increases the seal’s durability, is resistant to ozone, UV light and oxidation. All this increases the life expectancy of the sealed unit.A high desiccant content absorbs any moisture that is in the environment during manufacture improving the clarity of the unit.

Thermal Reinforcing

We all know how important it is to fit energy efficient windows, not only can they save your family money, they can also reduce your impact on the environment too.

But is there a way to make your energy rated windows work even harder for you? There is with Test Valley Windows!
As a company committed to environmental issues, we are constantly striving to improve the products we offer, which is why all our windows are now supplied with recycled PVCu thermal reinforcement.

What are thermal reinforcements?
Windows are traditionally manufactured with steel or aluminium reinforcement which provides strength and support. However, steel is not an insulating material, which means valuable heat can be lost directly through the material used to reinforce frames. PVCu thermal reinforcements are not only as strong as steel; they are the simplest way to boost the thermal efficiency of your windows. The unique multi chambered design creates a barrier against airflow travelling through the window, which minimises the heat which can be lost through your window frames.

All our windows are made to measure to ensure that your windows are designed to your requirements. Our representative will spend time listening to create a design and free estimate tailored to you, your property and your budget.
