Why should you use roof insulation and/or ceiling insulation? What about having a nice cool home in summer and a nice warm home in winter. What about saving heaps of money you are paying if you haven’t got a well insulated roof. In a roof space, temperatures can often approach 60C or more during the day. Most of this heat enters the roof space through several processes. First, solar energy warms the roof, which then transfers heat to the rest of the roof space through conduction, convection and radiant heat transfer. The 60C temperature of the underside roof surface then drives the heat transfer process.
The most efficient insulating material for roofs is spray foam insulation. Applying this to the underside of the roof prevents the temperature being exposed to the roof space (the temperature driving the heat transfer). Roof Insulation is reduced by as much as 50%. Both conduction and convection heat transfer are proportional to a temperature difference, so that heat transfer will be reduced accordingly with a drop in surface temperature.
The same applies to ceiling insulation. Ceiling insulation stops any residual heat (or cold) propagating downwards. It also has the benefit of stopping any heat transfer during the winter months escaping into the roof space. Ceiling insulation also gives the benefit of reducing any cool air escaping during the summer months.
The benefits of using spray foam roof insulation:
- Duct leakage and heat loss or gain from ducts are much less of an issue.
- Air sealing is easier in the roof than in the ceiling.
- Dust and loose insulation are less likely to migrate down to the living space.
- Energy costs are lower when the attic is sealed.
In conclusion, spray foam roof insulation and ceiling insulation reduces energy costs and loss in several ways. Energy loss from ducts located in the attic is essentially eliminated. The top of the building is much tighter resulting in less infiltration and exfiltration, so excess moisture isn’t pulled into the attic. Infiltration through the ceiling is also reduced. In addition, the attic temperature is lower. Roof insulation also further reduces energy loads.
If intending to convert your roof space into another room this is an ideal time to apply spray foam insulation prior to doing this. With attic roof insulation, you will reap the benefits for years to come.
