A PVC Conservatory Roof for All Seasons – Solar Control Glass

Have you heard the expression.. “Conservatories are too cold in the Winter and too hot in the Summer?

That’s quite correct, most are. But NOT a Hallmark PVC Conservatory or PVC Orangery.

The temperature in a conservatory depends upon the correct combination of glazing material and ventilation.

We provide the correct glazing for whatever position your pvc conservatory sits in relation to the Sun. Obviously, if it’s on a north facing wall, in the shadow of a two storey house, then you won’t require solar control glass in the roof. However, you will require a glass with a good insulation value. Hallmark provides insulating glass options right up to the highest available in the domestic market today.

If your pvc conservatory is exposed to sunlight for more than a couple of hours from 10am until 4pm, then you shouldn’t contemplate having a glass roof without investing the small extra it costs to install Solar Control Glass. Hallmark Conservatories offer the highest specification Celcius range of glass. For south facing roofs, we recommend the soft blue tinted, Celcius Elite solar control glass which keeps out 78% of unwanted heat from the sun on hot days, but it is also the most efficient double glazing with a u value* of 0.9 kw/sq.m/hr, 25% more efficient than the glass being offered by most of the competition and 3.5 times more efficient than most of the double glazing fitted during the past 30 years.

Where a clear solar control glass is required on south facing frames, we recommend Celcius Clear solar control glass, which keeps out 55% of unwanted heat and with a u value of 1.0 kw/sq.m/hr is still 3 times more efficient than most installed double glazing and 18% more efficient than most double glazing being offered.

* We are often asked “What does a u value mean?” Quite simply all external surfaces of a building have an insulation value and a u value is a measure of heat loss, per square metre, per hour, in Kilowatts. So a single glazed piece of glass typically loses 5.6 kilowatts per sq.m per hour. Most double glazing in the 1960s, through to the 1980’s, had a heat loss of approx. 3 Kilowatts per sq.m, per hour. With the introduction of Low-E glass (Low emissivity) and Argon gas filled sealed units, coupled with the introduction of stricter Building Regulations in 2002, windows installed after this period had to have a maximum of 2.2 Kilowatts heat loss per sq.m, per hour, which has more recently been reduced to 1.6. Remarkably, these regulations do not apply to conservatory installations, and most installers still fit glass of low efficiency, perpetuating the myth that conservatories will be ‘too hot in the summer and too cold in the winter’. At Hallmark Conservatories, we ensure you are provided with the best advice and the most appropriate glass for your pvc conservatory or orangery installation
