We have been manufacturing high quality PVC windows and PVC doors, for new or replacement installation, to DIY and trade customers for 28years. We fabricate the frames in our Bristol factory using 'Synseal Shield' 70mm profile, internally beaded and with 28mm glass units.

(Internet Explorer…. needs IE8 or later version (not fully functional on older IE7)

Just enter the sizes of the windows you need using the slider bars or enter sizes directly into the boxes provided and you will be given prices for any size of window in any of the energy ratings for any of our profile options, scroll down to add cills or patterned glass and be able to print the results or save to your computer (help button available).

You can print out a single item or multiple items and send it to us as an order form, or call in and see us.

Or.....for price guide only, scroll down to see our 'any-size-up-to' details.

All of the windows and doors that we make are made to measure, we do not stock ready-made items.

PRICES SHOWN BELOW ARE FOR "ANY SIZE UP TO"

You can look at the style of window you want and see the prices printed for that size category (if you are a few mm oversize in one direction, we will give the lower price)

Prices are banded A,B,C (Window energy rated bands, or "WER's"

For more details see "WER's"

A is the highest rated....with 'Swiss V' spacer bar ours are A+5....(prices in dark green).

B is the mid range (prices in blue/green)

C is the minimum requirement for building regs (prices in light green)

White, internally beaded, pre-gasketed frames with 28mm clear glass units incl. vat.

Woodgrain windows, mahogany or light/golden oak both sides ...plus 25% of white window price.

Woodgrain on white windows, mahogany or light/golden oak outside, white inside....plus 20% of white window price.

If the window style/size you want is not on the above list we can price it for you.

You can telephone us and we will give you a telephone quote.

You can email us and will will give an email quote.

You can call in to see us and see frames being made, we wil quote you.

Benefits of our system as compared with chain store items.

• Our prices are comparable with ready-made windows from the chain stores, but our windows are made exactly to your sizes.
• All of our windows conform to the minimum requirements 'Building Regs' Oct. 2010, Beware, if you choose to buy 'off- the- shelf' items, ensure that they comply with Regs.
• Our frames are 70mm (not 60mm) Our glass units are 28mm, (not 24mm).
• For patterned glass panes, you DO have a choice.....anything from the Pilkingtons texture range.

Pilkingtons Texture click to go to Pilkingtons website, then click below the picture on the right to view texture range.

Important Notes

Maximum width of a side hung vent is 650mm
Maximum width of a top hung vent is 1250mm
Maximum height of a side hung vent is 1250mm
Maximum height of a top hung vent is 1250mm

Vent sizes are measured from edge of frame to centre line

Transom - Standard top vent drop is 350mm

Mullion - Standard side vent width is 600mm

Please deduct any tolerances for fitting and give us the actual manufactured sizes of the frames!

Extras

Cill, 150mm wide, white, including end caps @ £6. per metre

Cill, 85mm wide 'stub' cill often used where there is an existing stone or tile cill, white @ £6 per metre

Frame extension, 20mm, £3. per metre.

Silver handles...£3 each

Gold handles...£3 each

Patterned glass...£8 per piece. (Texture, or patterened, glass in any of the Pilkingtons Texture range can be supplied.)

Trickle/night vent ...£15 each

Extras for your window might include a trickle vent ,also called a night vent, this provides a small amout of secure ventilation whilst windows are closed. Or you might like to have a woodgrain effect for your windows, this is available in mahogany or light/golden oak. We can manufacture both coloured types either with colour visible on the inside and outside of your home or as coloured on the outside and white inside. we can also fit silver or gold handle instead of the standard white.

You can fill in the sizes of the window on our order form, alternatively you may wish to draw the window on a separate sheet.

Sliding Sash Windows. (uPVC)

We also supply a range of uPVC sliding sash windows in white or woodgrains.

Prices on application.

Wide range of configurations - furniture. Call in to see sample in showroom and discuss.

Window Energy Ratings (WER’s)

Briefly....

Window energy ratings are A B C D E F Just like the labels on your new fridge/ washing machine.
A is the highest rating (most efficient) F is the lowest rating.

Building Regulations.
From 1st October 2010, the new building regulations require that a MINIMUM of C rating is used.
(or at least a U Value of 1.6 w/m2)

Our standard windows comply with the minimum C rating,
however, we can easily upgrade to B rating or A rating for a small additional cost.

More detailed explanation

The thermal efficiency of a window depends on the performance of both the glass and the frame.

The Specific calculations are quite complex, so to make it easier for the consumer to recognise the thermal quality of the windows, they have been banded into groups A, B, C etc.

Frames........

Multi chambered frames, are thermally more efficient than single chambered frames.
Many modern frames are 3 chambered, some 5 or even 6. the greater number of chambers increase the thermal efficiency, but reduce the ability to insert reinforcing.
Reinforcing (usually steel or aluminium) has always been needed to reduce distortion under load or increase stability for wood grained profiles and improve Screw retention for security furniture.

Recent Frame developments........

Thermal Inserts have recently been introduced
These effectively increase the number of “thermal chambers” in the main profile to 8 chambers
At the same time, rigidity of the frame is enhanced, so that usually, no further reinforcement is required.
In some circumstances, such as woodgrain profiles, additional steel reinforcement is applied.
But as this is fitted within the Thermal inserts, then thermal losses due to conductivity of steel are minimised.
Tests have shown that Furniture screws, into the Thermal Inserts give similar screw retention properties as steel. Another advantage is that screws will have less tendency to corrode when applied to thermal inserts, rather than steel (as the screws are fitted, they leave swarf which corrodes & breaks down the screw coating). Overall the frames with thermal inserts are the most cost effective solution.

Glass Units........

Generally, the larger airspace the better the thermal efficiency (up to 20mm airspace)
The addition of Argon gas (90% by volume) also improves the thermal efficiency.
“K” glass (hard coat Low emissivity glass) on the inner (room side) improves thermal efficiency by reflecting radiated (infra red) energy back into the room.
Soft Coat “Low E” glass does the same as “K”, but much more efficiently
Aluminium spacer bar is less thermally efficient than the new “Swiss V” composite spacer Bar.

Our Frames............

Synseal “Shield” 70mm system, internally beaded
For windows to achieve equivalent “B Rating” we use the following.

Thermal inserts in frames.
Glass units with “Soft coat Low E” plus Argon 90% fill with aluminium spacer bar.

For C rating we use glass units with soft coat 'Low E', air filled and aluminium spacer bar.

Upgrade to A
Specification as for B, but with Swiss V Spacer Bar(insulating Spacer Bar)

We recommend the upgrade option A.
Because Fensa & Building control have indicated that they will accept the glass label
as sufficient evidence that the window complies to (at least) the new minimum requirements.
(Without having to produce complex individual reports for each frame).

Documentation
We have copies of Full simulation reports from Synseal Extrusions Ltd. for the A,B andC ratings.
Each report is 10 pages. And can be viewed at our showroom.
Copies are available by post on request.
The reports are prepared by an approved Simulator (080) by
