Downlights add a lot to the aesthetics & ambience of our homes.
The trouble is they can cost us more than we think!
It’s not just the lights themselves including the lamps (bulbs) and fittings; there’s also the running cost of the electricity.
The install can be 50w lamps with 6, 10 or 20 per room and seldom fewer than 4 per room.
But that is not all, because downlights are a very weak point in the fight against heat loss.
Downlights can reduce the effectiveness of loft insulation by as much as 30%, owing to gaps in the insulation around the lights.
Uncovered downlights create what we at Thermahood call “heat-loss highways” – down which your precious heat will escape!
Above shows what happens in a typical house containing downlights with no covers
Below is a close-up view showing how air leaks at each downlight fitting with attendant heat loss
Missing insulation and these “heat-loss highways” contribute to other problems in the home that can be difficult to assess – never mind fix!
Condensation created when warm and cold air meet, or simply generated in the kitchen or bathroom, can cause rotting timbers & roof damage. Furthermore, damp, condensation and mould are linked to health risks.
Uncovered downlights also undermine our efforts to block out unwanted noise. (Part E – Building Regulations)
Pest infiltration: flies, spiders and all manner of creepy crawlies are drawn to light and can then make their way into your home.
Rodents are attracted to the heat and can nest nearby - they leave droppings that can end up in the face of the person changing a fitting or just a lamp!
Air quality is degraded because of dust contamination – and concern at the resulting health risks of this is growing all the time.
At Thermahood we recognise all the above problems as significant not only for the householder but for tradesmen especially working in these environments on a regular basis.
