Why Insulate Your Flat Roof?

Flat roofs are becoming increasingly popular in Reading and the UK, mainly because they offer several benefits compared to traditional pitched roofs. Flat roofs are usually less expensive, easier to install, and allow more living space under the roof. However, they typically offer poor insulation, which can lead to significant heat loss, especially if they are used as an outdoor living space or a roof deck. Insulating your flat roof can help you overcome this problem and give you the following benefits:

• Reduce heat loss in the winter and retain heat in the summer.
• Lower the cost of heating and cooling your property.
• Prevent moisture damage to the roof.
• Improve the performance of the roof, leading to an extended lifespan.
• Reduce the risk of fire and increase the fire rating of the roof.

What Type of Insulation Should You Use?

When it comes to selecting insulation for your flat roof, there are several options available, including:

1. Rigid board insulation: This is the most common type of insulation for flat roofs. It is generally made of materials such as polyisocyanurate (PIR), expanded polystyrene (EPS), or extruded polystyrene (XPS). Rigid board insulation can be used for both warm and cold roofs and is usually easy to install.

2. Spray foam insulation: This type of insulation is usually reserved for specialist applicators due to its complex and technical nature of installation. It is made of special chemicals that react together to form a foam that will expand to fill all areas of the roof. Spray foam insulation is ideal for irregularly shaped roofs or roofs with a lot of penetrations.

3. Warm Deck Insulation (Powerdeck): The Powerdeck system is a warm deck flat roof insulation system with a rigid polyisocyanurate (PIR) insulation layer bonded to a tough exterior grade plywood deck. It provides a continuous layer of insulation over the top of the roof deck, which eliminates any potential cold bridging and offers additional deck protection from the elements. It is ideal for new builds but can also be retrofitted to existing flat roofs.

What Thickness Insulation Do You Need?

If you are looking to insulate your flat roof, one crucial factor to consider is the thickness of the insulation required. The thickness required generally depends on the type of insulation used, the overall building efficiency of the property, and any local building regulations. The unit of measurement used for insulation thickness is R-value. The higher the R-value, the better the insulation.

For flat roofs, the recommended R-value depends on the insulation type and the location of the property. For example, Reading is located in Zone 2 of the UK, which requires a minimum R-value of 5.5 for flat roof insulation. Here are examples of the recommended minimum thickness of insulation for flat roofs:

• Rigid board insulation: 120mm of PIR, EPS or XPS insulation.
• Spray foam insulation: The thickness required due to the expanding nature of the insulation can vary, but we recommend with this method, 100mm or more is needed.
• Powerdeck insulation: 160mm of PIR insulation (the thickness will vary depending on the manufacturer's specifications).
