A great solution for old houses

Service rating : Very helpful on the phone.

Product : A very effective solution for old or listed houses. Made a big difference to warmth and draughts. Installation relatively straightforward, except that old windows without right angle corners can be tricky.

We’ve had it installed for several years now, and very pleased. The only other option would have been to remove our original 1913 sash windows, and replace with brand new.

Easy house insulation.

Service rating : Yes

Product : It is easy to install and very effective for preventing condensation on cold nights. Our house is definitely warmer.
My only criticism is the black line that can be seen around the edge.

Reply from Extraglaze:
Thank you Michael for your very positive feedback. For readers of your review I hope to explain: the black line is the 1.5mm thickness of each magnet which can only be seen when viewing the window at an angle. For many customers the sides of a window are covered by a curtain, or because the window is set within the thickness of the wall you can't easily look there. Customers generally look through the window during the day not at the frames, consequently their eyes are adapted to the brightness of the view outside. The line you mention is then hidden in dark shadow, as a result of contrast. In the evening most windows will be covered by drapes of some sort, so the panels are not visible then anyway.

All round good product and good service.

Once installed virtually invisible.

Service rating : Delivery much quicker than quoted, and contacted me ref a couple of measurements to ensure they were correct.
Product : Very effective for curing a very bad condensation issue, and a bonus that they also, stop lots of draughts.

Does what it says it will.

Because of the colour of our frames It is almost invisible in some of the rooms.

Service rating : You need to be sure there’s a smooth surface with no ridges all the way round but If you measure correctly It is easy to apply and certainly works.
It’s a thoroughly good effective...

Veritherm case study – Extraglaze comes out top

Extraglaze was installed as part of a real life case study, in a real home, and the results measured and reported by Veritherm.co.uk

Green Homes Grant

(announced 7th July)

Important update for October 2020: Extraglaze has given great consideration to the Green Homes Grant, and has declined to take part.

Extraglaze at the National Trust offices, Hidcote Manor Gardens

February 2020

We are very proud to have installed our magnetic secondary glazing at the National Trust's Hidcote Manor Gardens, in the staff offices – to keep everyone warm in rooms where other potential secondary glazing solutions had been considered out of the question.

Safety hook

£1.19 each

Size (external)

– +

The 'Add to basket' button will appear after you respond to all of the Please select... options above.

Important guidance is shown below

Shoulderless safety hook, as described in our Guides.

Stainless steel, self colour. Sizes are approximate.

APPLICATION: Think "fall-safe". Use these to reduce the risk of a fall. Install two of these hooks beneath any panel that is not close to a sill or similar ledge. ALWAYS INSTALL SUFFICIENT HOOKS IF FOOT TRAFFIC IS BENEATH A PANEL. Do not hesitate to apply additional safety measures. Note for tall panels and especially panels that receive a lot of sunshine: if these panels come loose these may flop forward with a duck-under motion, so fit one or more hooks either side as the situation requires. Supplement with or exchange for curtain wires where prudent.

INSTALLATION: Fit with a small gap not exceeding 3mm to the panel edge. Prepare a pilot hole using a 2.5mm or 3mm drill bit, then fit the hook. Take great care - the drill must not touch the panel. Use a tiny dab of lubricant such as salt-free butter or spread. Do not exert the screw with much more than finger strength or the screw may break (stainless steel is not as tough as regular steel). When screwing into a window frame the short leg will rotate like a clock hand, therefore it needs a 15mm radial clearance.

IN USE: the short leg should sit over the panel edge with no more than a 3mm gap. A quarter turn (finger strength should be sufficient) will allow the panel to be removed.
