Energy Efficient Warm Roof

Thermal Insulation

With the thermal insulation layer located between the ceiling joists so that everything above the insulation (any roof space) will be colder than the living space below it. As can be seen from the illustration, that is how the warm roof is constructed, ensuring the empty spaces are well ventilated (as a traditional roof would be) to avoid condensation. By using 155mm EPS insulation we ensure that the “cold” from this roof stays well away from the room.

Will I be able to use my room all year round?

Yes. The addition of a warm roof can make your room up to 90 percent warmer in winter and 70 percent cooler in summer. Additional benefits include reduced noise pollution and no solar glare.

Do I need planning permission?

In most cases no. An Icoview conservatory is fully compliant with building control regulations. The Icoview is also system approved with a number of building inspectors to simplify the building control process.

Will the roof be too heavy for my existing frames?

No. A warm roof is only marginally heavier than a glass roof. As per LABC guidelines (April 2016), if the structure shows no signs of distress, the existing foundations are likely to be adequate to carry the small additional loadings. Existing glazing and door support must also be reinforced.

Will my internal room feel darker?

Yes it is estimated you will lose between 5-10 percent of light following the installation of a warm roof. You may wish to incorporate one of our premium Velux roof windows with high performance glass to let in extra sunlight.

Is condensation a real issue?

Very much so, which is why an Icoview is a fully ventilated system and uses timber that is both strong and has low thermal conductivity.

Will the roof be strong enough to stand on whilst I clean my windows?

Recent testing proved a 6.4m x 6.4m Icotherm roof could carry the weight of four modern Mini cars without showing any signs of movement.

How long will it take to complete the work?

Whilst no installation is the same, an average conservatory roof upgrade is completed within 2-3 days.
