Open Plan Home With Bi-fold Doors Overheating
Not to have an unbearably hot home. Modern insulation and lots of modern glass generally means that the internal spaces over heat considerably. The absence of small opening windows in on the south facing ground floor meant a Bi-fold door had to be left open to ventilate which isn’t and option if the property is unoccupied. The owner looked at many options such as awnings and air-conditioning but after careful research by this major airline captain he decided solar control glass coatings were going to be the best option and turned to us for advice.
Discussing the degree of overheating with the customer who had kept a temperature log over the previous weeks and months and the other issue of addressing a privacy issue at the front of the property and a desire to protect all their furniture, carpet and wall pictures we approached this in two halves. The hot south facing rear of the home an external Solar Gard Silver 35 (medium) for a 64% solar heat gain reduction was specified; an internal equivelant version on modern glass can only achieve around 30% heat gain reductions. The front of the property where privacy was the main concern an internal Solar Gard Silver 50 (light) film was used to give increased privacy, fade reduction and and kerb appeal to the home.

Instant temperature difference thought the whole home, increased privacy and increased sun damage protection has made this home now usable with zero running costs or additional or annual maintenance costs. The customer also loved the look of the home visually and felt reassured their children can’t be seen from the nearby road.
I found CoolGlass through the Saint Gobain Glass company website, as a recommended fitter for their UV/IR window films. Mark was extremely professional in his appraisal of our needs, and did not just try to sell us the most expensive product; but the ones most suitable to our individual requirements for all the different large windows in our house. The quote was competitive, and the standard of fitting was excellent, with Mark and his colleague being pedantic in ensuring each window was perfect before completion. The difference it has made to the internal temperature of our modern house (see picture above of the White house with two bi-fold doors) is astonishing. Being south facing at the rear the internal temperature in the open plan living area was reaching 33-34 degrees on a 28 degree outside temperature day with full sunlight on the bi-folds before the film was fitted. On the first comparable day after fitting we saw a highest internal temperature of 23 degrees. In addition the improvement in privacy at the front and rear of the house, plus the added advantage of the prospect of almost no fading of wooden floors and furniture due to the filters, means that this has made a dramatic improvement to our house, and at a fraction of the cost of installing air conditioning (the other alternative we investigated). I would not hesitate in recommending Mark and CoolGlass if you are looking at trying to reduce glare/temperature/fading and increase privacy in your homeBen 20/08/2017
