Good thermal insulation in a loft conversion in Edinburgh

A house with an attic enjoys additional insulation compared to those that do not have this space.
Moisture and cold air might enter the home through the air vents in the roof. Thus, the house is better thermally insulated. The heat will be maintained not only in the attic, but in all rooms. Providing much more coziness than other rooms, the attics and lofts are located on the top floor of the house.  This, gives them more isolation from the other rooms and, implicitly, more privacy. In addition, the main feature of an attic and loft – narrow walls and sloping ceiling – gives it a comfortable and romantic look.

How much of the heating can be lost through an uninsulated roof in Edinburgh?

 
In Edinburgh, an uninsulated roof can result in 25-30% of total heat loss from a building, depending on its size and construction.
 
 This equates to thousands of kilowatt-hours of wasted energy and hundreds of pounds in additional heating costs annually. 
 
Insulating the roof during a loft conversion in Edinburgh is a highly effective way to reduce heat loss, save money, and improve the overall energy efficiency of a home.
 
If you’re considering insulation, it’s worth exploring options like:

– mineral wool,

– rigid foam boards,

– Expanded Polystyrene (EPS),  or

– spray foam,

which can significantly improve the U-value of your roof. 
 
Additionally, government grants or incentives may be available to help offset the cost of insulation upgrades in the UK.
 
Thickness of insulation recommended during a loft conversion in Edinburgh 
 
The recommended thickness of insulation for a roof depends on:

– the type of insulation material used,

– the desired thermal performance (U-value),

– the specific climate conditions of the location, such as Edinburgh.

In the UK, building regulations provide guidelines for insulation thickness to achieve energy efficiency standards.
 
 Here’s a detailed breakdown:
 

1. Building Regulations (UK) regarding insulation thickness for a loft conversion in Edinburgh

The Part L of the Building Regulations in England and Wales (and similar standards in Scotland) sets minimum requirements for thermal performance.
 
 For roofs, the target U-value is 0.15 to 0.18 W/m²K for new builds and 0.16 to 0.25 W/m²K for retrofitting existing homes. 
Achieving these U-values typically requires significant insulation thickness.
 

2. Insulation Materials and Thickness for a loft conversion in Edinburgh

Different insulation materials have varying thermal conductivities (measured in W/mK), which influence the required thickness.
 Here are some common materials and their typical thicknesses to achieve a U-value of 0.15 to 0.18 W/m²K:

a) Mineral Wool (Glass or Rock Wool)

Thermal conductivity: 0.032 to 0.044 W/mK
Recommended thickness: 270 to 300 mm
 

b) Rigid Foam Boards (PIR or PUR)

Thermal conductivity: 0.022 to 0.026 W/mK
Recommended thickness: 150 to 200 mm
 

c) Expanded Polystyrene (EPS)

Thermal conductivity: 0.033 to 0.038 W/mK
Recommended thickness: 250 to 300 mm
 

d) Sheep’s Wool (Natural Insulation)

Thermal conductivity: 0.038 to 0.042 W/mK
Recommended thickness: 280 to 320 mm
 

3. Practical Considerations regarding insulation thickness for a loft conversion in Edinburgh

In Edinburgh’s climate, where winters are cold and damp, it’s advisable to aim for the higher end of the insulation thickness range to maximize energy efficiency and prevent condensation issues.
 Here are some practical recommendations:
 

a) Pitched Roofs (Loft Insulation)

For between-rafter insulation: Use 270 mm of mineral wool or 200 mm of PIR boards.
 For cold loft spaces: Lay 300 mm of mineral wool or 250 mm of EPS across the loft floor.
 

b) Flat Roofs

For warm flat roofs: Use 150 to 200 mm of PIR boards.
For cold flat roofs: Use 250 to 300 mm of mineral wool or EPS.
 

c) Hybrid Solutions

Combining different materials (e.g., PIR boards with mineral wool) can reduce overall thickness while maintaining high thermal performance.
 

4. Additional Tips when doing a Loft conversion in Edinburgh

Vapor Barrier:** In damp climates like Edinburgh, install a vapor barrier on the warm side of the insulation to prevent moisture buildup.
 
Air Tightness:** Ensure the roof is airtight to minimize heat loss through gaps and drafts.
 
Professional Advice:** Consult a building surveyor or insulation specialist to determine the best solution for your specific roof structure.
 

5. Cost vs. Savings when  arranging a Loft conversion in Edinburgh

 While thicker insulation involves higher upfront costs, the long-term savings on heating bills and improved comfort make it a worthwhile investment.
 
 For example, upgrading from 100 mm to 300 mm of mineral wool in a typical Edinburgh home can reduce heat loss by 60-70%, saving hundreds of pounds annually. So, Loft conversion costs in Edinburgh can be worth the investment. 
 

Summary for a loft conversion in Edinburgh 

For roofs in Edinburgh, when doing a loft conversion, the recommended insulation thickness is:
Mineral Wool:** 270 to 300 mm
PIR/PUR Boards:** 150 to 200 mm
EPS:** 250 to 300 mm
 
These thicknesses align with UK building regulations and ensure optimal thermal performance in Edinburgh’s climate. Always consider the specific characteristics of your roof and consult professionals for tailored advice.
