Conservatory Uneconomic or Expensive to Heat?

Conservatories have high heating costs because their roof insulation is inadequate. Typically 80% of heat loss is through the roof


Our Thermo 60 and Thermo 80 replacement roof panels and roofs have exceptional insulation performance for economic heating without loss of light :

TickWarm and Comfortable conservatory in Winter. – cutting heat loss by up to 80%.
TickCutting the cost of expensive heating. – Our high insulation energy saving products cover their cost over and over again.
TickCool, glare free and comfortable in Summer. – excluding 80 % of summer heat.
TickAdd the conservatory to your living space. – as a dining room, lounge, or haven of peace and comfort.
TickDramatically Transforms the Appearance and Light. – New conservatory roof panels and components, completely transform the appearance to look as good as new.

‘Thermo’ Roofs – Superior Insulation performance to solid roofs without loss of light

Our ‘Thermo 60’, and ‘Thermo 80’ range are designed for Polycarbonate and Glass roofed conservatories to provide comfortable all year us of the conservatory so that it can be added to your living space.

The Thermo range can provides superior insulation to Solid roofs without loss of light, and has the best insulation performance of any transparent roof system. Please see below for full details:

We offer three high insulation solutions for all year comfort and to cut your heating costs :

1) High Insulation roof panels – Energy rating ‘A’ PLUS – U value 1.0 watts/M2 °C.

Thermo 60 roof refurbishment -We install Thermo replacement roof panels and all accessories to totally refurbish your Polycarbonate roof .These cut roof heat loss by up to 60% to enable the conservatory to be added to your living area. In addition the refurbishment transforms the appearance of the conservatory to look as good as new. Highest Energy rating equivalent GRADE ‘A’ PLUS . U value 1.0 watts/M2 °C.


2) High Insulation roof panel upgrades -Energy rating ‘A’ + + – U value 0.6 watts/M2 °C.

Thermo 80 roof. This system comprises of the Thermo ’60’ system, with the addition of transparent insulating panels neatly installed between the internal glazing bar rebates to ensure that there is no change in the internal appearance, and thermal breaks to cut heat loss through the structure of the conservatory. The result is a system that cut heat loss by up to 80% to provide insulation equal to a filled cavity wall significantly surpassing all other transparent conservatory glazed roof solutions. Energy rating equivalent GRADE ‘A’ ++. U value 0.6 watts/M2 °C.

All our roof solutions are available with heat reflectors for Solar control and further enhanced Winter insulation performance. Click the links below to see Performance tests for Glass Conservatory roofs and polycarbonate conservatory roofs.

Convert your Conservatory into a Passive Solar Collector with our high performance roof panels.

During the late Autumn, Winter, and early Spring, when heating is required in the home, the Sun is relatively low in the sky and predominantly shines in to heat the conservatory through the side window glazing. Normally this heat is rapidly dissipated through the roof. But when high insulation roof glazing is installed the heat is captured and simply flows into the house by opening the internal doors.

3) New Roof Structures with New Conservatory Roof panels

It is rare that a conservatory requires a completely new roof structure but if needed we can provide this including all components: glazing bars and cappings, eaves beams, wall plate, gutters, and glazing. With our specialist components we can refurbish/repair and upgrade the existing roof with high performance roof glazing, and thereby avoid the expense and disruption of removing and replacement of the whole roof, or replacing the conservatory.

Our experience however tells us that where a Ultraframe 500 and Everlite roof comes to the end of its lives it is best to change the roof structure for the modern roof system. Based on glazing bars, now typical of most conservatories, and our high performance glazing to provide: exceptional winter insulation, and where required solar control for winter and summer comfort so that the conservatory can be used throughout the year as part of the living area.

Summer and Winter Comfort : All three roof systems are available with solar protection and glare control if required. To give all year comfort by : combat high summer temperatures, glare and fading, as well as providing winter comfort and lower heating costs.

The heat reflectors products can also be fitted to existing sound roofs in-situ to upgrade their performance. For full details please click the following link.

Replacement of individual Roof panels that have deteriorated

Where the Conservatory roof structure and most of the panels are sound but some are showing signs of deterioration. We can either replace the failed panels like with like, or fit High insulation ‘Thermo’ roof panels in anticipation of the replacement of the other panels in due course.

Specially designed for Conservatory refurbishments, Thermo roof panels are the technically most advanced available. They have unsurpassed insulation performance, typically cutting heat loss by up to 80% – better than the best double glazing units. They can be supplied with transparent heat reflectors to exclude summer solar heat so that you can use your conservatory in comfort all year round with economic fuel bills.


If you wish to change your Polycarbonate roof to Glass

Generally speaking Polycarbonate roofed conservatories cannot be replaced with glass as the conservatory roof structure has only been designed to support the weight of polycarbonate at 3.5 KG per square metre, compared to glass at 32 KG per square metre. However certain conservatory roof system manufacturers use a universal system which will accommodate glass or Polycarbonate double glazing units. We can identify these and advise you once the conservatory is inspected to determine the roof manufacturer.
