Product: Secondary Glazing

First up I wanted to say thank you for the exemplary way you dealt with my recent order for secondary glazing. Your website is great and told me everything I needed to know before ordering, the online ordering process was straightforward, your team contacted me and put the order through quickly, the windows were carefully delivered by your own friendly and helpful driver, they are great quality, good value for money and fit perfectly. I'm very impressed and have already been recommending you to others.

Really delighted with our last order; looks superb!... I would be more than happy to endorse your products.

... Although we are not window fitters by profession we realised as soon as we saw these units that we would have no problem fitting them. We have been so impressed both with the appearance and performance of them that in December we ordered another three units... I will be suggesting to anyone who asks about this type of secondary double glazing that they send their enquiry to Duration Windows.

...many thanks for the 18 Secondary frames you delivered for us in March. The customer was so happy with the difference in warmth to his cottage and now the lady next door wants hers doing.

Product: Secondary Double Glazing

I have recently fitted the two windows I ordered a few weeks ago and I was very impressed with the quality and service you provide. More importantly the customer is over the moon with them. They were fitted in a private lounge of a Tudor period bed and breakfast house which fronts directly onto a road with pubs and eateries nearby, with the subsequent noise from the original very thin and draughty windows - what a difference they make! and good looking too. So impressed are they that they would like to go ahead and order the windows for all the front facing bedrooms windows...

Thank you for another accurate, prompt and well made order. The house is now ready for next winter, or this summer if it doesn't improve, with all windows fitted with your excellent units. I shall recommend the company to all I meet and will come back again should the need arise.

Product: Secondary Glazing

I have had a couple of quotes for some more secondary glazing. Duration have come out tops again and I was very pleased with the service and units that you sent me before. They are top quality and so easy to fit. The difference they have made insulating both sound and heat is phenomenal.
- D.B.

Product: Secondary Glazing

Many sincere thanks. I live in a small village in Grade two listed building 3 yards from a main road and 90 yards from a church. Your windows have made us so much warmer and can sleep so I am glad that I have always recommended your windows for sound protection and insulation.

Product: Vertical Sliding Secondary Glazing with acoustic glass

The 2 sash windows you just supplied are superb and have already made a big difference to my daughter's bedroom both in terms of noise and draught prevention. I will (and have) be recommending you to my friends.

Product: Secondary Glazing with acoustic glass

Just thought that I would email you with my comments following the fitting of your secondary glazing system with the stadip acoustic glass! Thanks for all your help with this, and can now report that after fitting they are fantastic. I bought them to solve the problem of living next to a busy main road, and yes the sound insulation is brilliant! I can now watch the cars go past in silence, and more importantly live and sleep in peace and quiet. The rooms with this fitted are now also noticeably warmer than the others, and no condensation problems have occurred. I will be in touch shortly to do the rest of the house.

I just wanted to drop you a note to say thanks for the window. My dad and I built and installed it last Friday and it looks great, and reduces noise levels considerably.

Product: Secondary Glazing

Just to let you know that I have fitted the secondary glazing units you supplied to London for me, and they are great. They have cut out a tremendous amount of noise and draughts. Thank you very much for your prompt delivery and the quality of your product.

Product: Secondary Double Glazing

Very, very pleased with the secondary double glazing unit. Easy and quick to fit in just a few hours and the acoustic glass has made a HUGE difference to the traffic noise. We sealed the edges (and the trim was stuck on with it too over the top), with 'Everbuild' acoustic sealant which we purchased for a few pounds from an online site. We would not hesitate to order from you again. Always plenty of help and advice available from you too which is reassuring when ordering online.

Thank you very much for another very well and accurately made product delivered very quickly. I will be placing an order for another four very shortly.

Product: Secondary Glazing

I have recently purchased and fitted secondary glazing with acoustic glass. All I can say is why didn't I do it sooner. The quality of the frames is excellent, fitting is so simple and the noise reduction is 100%. The only thing I can hear is a police siren faintly and I live next to a busy city centre road. Thank you for a hassle free ordering right through to delivery (only 3 weeks after ordering)

The secondary glazing arrived early Tuesday morning, delivered by a very helpful driver. The condition of the goods was excellent and within two hours it was in position. I shall be ordering more glazing before long. Thank you for your attention and for providing such a first class product.

I would like like to say thank you for the way you handled the order I made for the Secondary Glazed unit, the unit was fitted in no time at all and I must say this was the easiest way I have ever earned brownie points, now that the unit is fitted it looks great and it's so efficient too.

Re: Thanks! Hi, I just wanted to write a quick note to comment on the secondary windows I ordered from you. The build quality is excellent and the acoustic glass cuts down outside noise very well. Everyone I dealt with at Duration was professional, courteous and aimed to please. Top marks all round.

Product: Secondary Double Glazing with acoustic glass

I felt that I had to write to you about the manner in which the above order was processed. No praise is high enough when speaking of the quality service provided by your staff. They were helpful, polite, patient and extremely competent ----- from first contact to delivery. The product is excellent quality, well designed, well executed and produced on time. Thank you.

Product: Secondary Glazing with acoustic glass

Many thanks for the excellent product and service. The SDG units have been installed in a listed building in Tavistock. The planners, my tenants and myself are very pleased. Thermal and acoustic efficiency is excellent. The product was easy to specify and to install and is well made. All the staff I met on my three visits to Canvey Island were friendly, well organised, informative and helpful. Duration seems to be a happy and well run business. Just like British business should be.
