Icospan flat roof…


For orangeries, extensions and garden structures.

The Icospan is a premium roof flat roof solution, sought after to create beautiful orangeries with a central lantern or skylight. Designed around a warm roof construction, it retains the minimum disruption, a pre-assembled concept that has made our roofs so popular.

Energy Efficient

Thermal Insulation

The Icospan has a 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. An Icospan is constructed to ensure 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.


Obtain your Building Control certification easily with an Icoroof: should your installation require building control approval, you can select an Icoroof knowing that this process will be made simpler and faster; the Icoroof is pre-approved by Ball & Berry building inspectors. By using their services you do not need to go to the local authorities. Warm Roofs Direct has opted to use this facility for ease and speed.


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

Yes. The addition of an Icospan 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 Icospan roof is fully compliant with building control regulations. The Icospan 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. An Icospan 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. 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 Icospan 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.
