Thermal Insulation

With an insulation layer between the roof joists, so everything above the insulation layer (any space on the roof) will be colder than the living space below it. Built to ensure that the void space is well ventilated (like a traditional roof) to avoid condensation. By using 155mm EPS insulation material, we ensure that the “cold” from this ceiling is kept out of the room.

FAQ

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. Choose GREEN LID as your Flat Roof Contractor

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?

As your flat roof contractor, whilst no installation is the same, an average conservatory roof upgrade is completed within 2-3 days.
