High Quality Roof Insulation

Installing insulation in your roof is vitally important. Not only does it help regulate the temperature of your home but it saves you money in the long term by reducing your heating costs. During economic uncertainty, you need to ensure you have effective insulation in your roof and that’s something that N.H.R.B.S. will help you with when we install or replace a roof.

Up to a quarter of the heat in an uninsulated home escapes through the roof, which makes roof insulation one of the most effective ways to reduce your energy bills. Warm air rises, and in a typical London property the roof and loft space are responsible for a significant share of heat loss, often more than the windows and doors combined.

Insulating the roof properly keeps the warmth you pay for inside the building, helping you stay comfortable in winter and cooler in summer. Because our insulation is installed as part of the complete roof build-up, it works continuously for the life of the roof rather than settling or degrading the way older, loose insulation can.

For pitched roofs, we use either TLX Gold Insulation or YBS Breathable Insulation. Both are good options and we choose the right one for the context of the roof we are insulating.

YBS Breathable Instulation is simple to install. It has high thermal performance, meaning it will keep help keep your home warm, and it is also water resistant and vapour permeable making it durable and sustainable. While only 40mm, it is highly effective at maintaining the building's temperature when installed correctly, making it a great choice for your roof.

The other option we use is TLX Gold, which is a breathable, layered multi - foil insulation that responds to changing humidity.It meets the relevant regulatory standards, meaning it won’t allow water and condensation to build up in your roof.

For flat roofs, we use Thermaroof insulation board by Kingspan for its high performance, excellent temperature efficiency and wide compatibility. Thermaroof insulation is easy to install and is certified as “Very Good” by the relevant industry standard. It also has high ratings for fire safety and environmental sustainability.

When installing Thermaroof, we put the insulation board on top of the decking 120mm thick to provide the best level of insulation for your home.

If you are installing insulation for a loft, a cheaper option is to put 300mm loft insulation on the floor of the loft. This will help keep your home below at a comfortable temperature.

Whether you are in need of a new roof, a roof replacement, or a loft conversion, we have the expertise to complete your job to the highest standard of excellence. We will also ensure the insulation is installed professionally to help keep your home protected against extreme temperatures, saving you money on your energy bill.

Correct ventilation matters just as much as the insulation itself. Warm, moisture-laden air from the rooms below rises into the roof space, and if it cannot escape it condenses on the underside of the roof covering, leading to damp timber, mould and rot in the roof structure. That is why we fit vapour-permeable membranes such as TLX Gold and YBS Breathable Insulation on pitched roofs, which let moisture escape while keeping the heat in, and why we always maintain the air gaps and ventilation routes the roof needs.

Insulation that is installed carelessly can also compromise the guarantees that apply to the rest of the roof, which is one reason ours is always professionally fitted as part of the complete roof build-up by experienced roofers. Every new roof and roof replacement we install is covered by our 10-year insurance-backed guarantee, and because we obtain a building control certificate for the work, you can be confident that the insulation, ventilation and fire safety requirements have been met.
