Building Insulation – Is it Cost Effective?
on 23/04/2019

For many years now the message has been pure and simple: We need to cut down our consumption of energy. Not just because a lot of it is wasted unnecessarily but also because this waste has a significant effect on the environment.

How Much Energy are you actually losing?

With regards to wasted energy in the home, insulation is the way forward. Research by the UK’s EST (Energy Savings Trust) indicates that a property without insulation looses a massive forty-five percent of the heat inside through solid walls, twenty-five percent through the attic, twenty percent through doors and windows and thirty-three percent through various other types of wall. Without argument, that is a lot of waste and so a lot of money flowing out of your home every minute of every cold day – and there are a lot of cold days in the UK!

The Research Speaks for Itself

Just looking at the numbers above, it is easy to understand the importance of building insulation – Really and honestly, it should be a no-brainer! However, like everything else the costs have to be weighed up. The materials used and other factors (such as where the pipes are etc) can change the costs as well as how effective the insulation is. This is why many people contact a specialist to make sure they get it right. Without doubt, the most expensive way to do it is without knowing what should be where and having to do it all again – As they say, no point putting a plaster on a broken leg.

Concrete Block Insulation

If you are building with concrete blocks the cores can be filled with insulation like polystyrene beads or rigid foam. However, this is only possible if they do not need to be filled with steel or concrete to strengthen the structure. Another alternative is to add a rigid foam or foam board insulating layer to the exterior or interior of the existing wall surface.

Blanket Insulation

This is one of the most common insulations used for loft areas, between stud walls and under floor joists. Blanket insulation is often fibreglass but mineral wool, cotton ans sheeps wool as well as plastic fibre mixes are available.

Window & Door Insulation

If you are not particularly good with your hands and DIY sealing up windows and doors can be a messy business. Some of the most popular options are:

Weather Stripping & Foam Tape – A cheap way to fill in small gaps between the window and the frame.

Rigid Foam with Foil Stripping – This is like weather stripping but thicker and stronger. Primarily used for house doors and garages

Window Film – This has been around a couple of decades now. It can be added to the inside or outside of the window and is effective enough to be used on boats and cars as well as homes.

There are many ways to insulate your home economically and effectively. The costs pretty much pay for themselves in a short time. Without doubt, when it comes to reducing energy bills the importance of building insulation is paramount.
