As heat rises, it can easily escape through a non-insulated roof – one of the most common forms of heat loss in homes across the UK. Here we answer all your questions about flat roof insulation – an excellent method to help save you money and keep you warm and cosy.
Benefits of Flat Roof Insulation:
- Improved Energy Efficiency: flat roof insulation helps to reduce heat loss in cold weather, leading to more stable indoor temperatures and decreased reliance on energy use, resulting in energy cost savings.
- Thermal Comfort: insulating a flat roof enhances thermal comfort within the property, creating a more pleasant living environment, helping to eliminate cold spots during winter and excessive heat build-up in the summer.
- Condensation Control: quality flat roof insulation systems include vapor barriers and ventilation to control moisture and prevent condensation within the roof, reducing the risk of mould growth and structural damage.
- Increased Roof Lifespan: flat roof insulation can protect the roof membrane from extreme temperature fluctuations and thermal stress, extending the lifespan of the roofing system.
- Building Control Compliance: newer building regulations require properties to have a higher level of thermal efficiency. By installing flat roof insulation, your property will adhere to these modern construction standards.
Frequently Asked Questions
WHAT IS FLAT ROOF INSULATION?
Flat roof insulation is a type of insulating system designed for flat roof structures, which do not have any loft space and have a pitch of less than 10 degrees. This type of system provides a solution to improve energy efficiency by installing insulation between the ceiling and the roof membrane, preventing any heat from escaping and providing protection against the elements.
ARE THERE ANY GRANTS FOR FLAT ROOF INSULATION?
You may be able to access energy saving grants for flat roof insulation via the ECO4 scheme, which is designed to help low-income and disadvantaged households benefit from upgraded energy efficiency measures to help them lower their energy bills. Zing Energy can help to see if you may qualify for an energy grant, plus can carry out flat roof installations across England and Wales.
WHATS THE DIFFERENCE BETWEEN WARM AND COLD ROOF INSULATION?
There are 2 main versions of flat roof insulation: Warm roof and Cold roof:
Warm roof insulation works by adding the insulation above the joists, which is covered with a vapour barrier, helping to reduce condensation within the flat roof space.
Cold roof insulation involves insulating between the joists, combined with a waterproof cover over the top. This system usually requires a roof void ventilation system to avoid the build-up of damp.
HOW LONG DOES FLAT ROOF INSULATION LAST?
In order for your flat roof insulation system to last, it must be installed properly by an approved and qualified installer, plus the type of product installed is also significant. At Zing Energy, all our flat roof insulation products installed by us, come with both a workmanship warranty and manufacturer’s guarantee, plus your install will be insured under an insurance backed guarantee scheme.
WHAT ARE THE CURRENT BUILDING REGULATIONAS FOR FLAT ROOF INSULATION?
In order to comply with Part L of the building regulations 2010, all roofs to rooms in ‘heated buildings’ must be thermally insulated to a maximum U-value of 0.18 W/m²K. (a lower U-value indicates higher insulation properties). The overall U-value of the insulation system will incorporate each component including the timber and plasterboard used, to the thermal performance of the insulation product.
