Windows and Doors

Do I need planning permission for double glazing?

If you are only replacing windows in a non-listed building then you should not need planning permission as they will have little impact on your neighbourhood and neighbours.

There are a couple of exceptions; if the house is a listed building (see notes below), if your house is in a conservation area, windows in flats and any buildings under Article 4 Directive.

We can still sometimes replace windows and doors under these restrictions, but your selection would be limited to those allowed by the relevant authorities.

Can I install double glazing in a listed building?

Listed buildings in England are protected by the Planning (Listed Buildings and Conservation Areas) Act 1990 this covers both the interior and exterior of the building.

You need to apply for listed building consent if:

  • the windows are to be replaced with a new style of window
  • there is a change to the materials used for the frames
  • there is a change in the type of glazing e.g. single glazing to double glazing
  • you wish to repaint existing windows a different colour to the existing
  • you are proposing to re-glaze, involving the loss of original glass.

If you are unable to have double glazing in your house, then secondary glazing is an alternative option that is not subject to planning permission and still offers many of the benefits of double glazing. We do not at present offer secondary glazing

Will I be able to have any choice in my windows?

If you are not bound by any restrictions as above, you have a wide choice of colour and style available to you, but this of course will depend on the size of the window and compliance with current Building regulations, for example bedrooms should have openings large enough to enable escape in case of fire.

What does U-Value and Window Energy Ratings (WER) mean?

The rate of heat loss is indicated in terms of the U-Value of a window. This is for the whole window assembly (including the glazing, frame and spacer bar). The lower the U-Value the greater a windows resistance to heat flow, so the better its insulating property is.

The Windows Energy Rating (WER) is an important thing to look at when looking for your windows. They are very similar to the energy ratings on electrical goods.
From the most efficient A+ to G which is a very inefficient window.

The Windows Energy Rating is calculated using the following values

U Value – Thermal Transmittance, G Value – Solar Factor, L Value – Air Leakage

What is the difference between Casement windows and Flush Casement windows?

As the name suggests Flush casement windows sit flush in the frame and do not have the lipped appearance of a normal Casement window.

The choice is purely an aesthetic one.

What is the difference between Double and Triple glazing?

If you want the most thermally efficient home and want windows that will conserve the heat in your home, Triple Glazing is the best option. An added bonus is that triple glazing reduces external noise more than double glazing.

What is the thickness difference between Double and Triple glazing?

Double glazed glass has an overall thickness of 28mm with Triple glazing being 40mm to accommodate the extra layer of glass.

What is the difference between Composite and PVC doors?

Composite doors are manufactured using a variety of materials including uPVC, wood, insulating foam and a GRP skin ( Glass Reinforced Plastic ). The result is a very strong, secure door with a great variety of colours and styles available. These are mainly used for the front of properties.

PVC doors are made from PVC plastic. The internal panel can be a mixture of PVC and Glass or a purely glass panel. These can allow for a lot of light into the home. They are not restricted to a size of the panel and can be a great option for usual sized doors. These are mainly used for the rear of properties.

I have an unusual door opening size, can I still get a door to fit?

Some of the Composite door choices may not be offered but other options will be available to you. Your surveyor or advisor will be able to inform you of your choices.

Can you make a door suitable for disabled access?

Yes we make doors with low thresholds and extra wide for disabled access, although some of the composite door styles are not available. Your surveyor or advisor will be able to help you with your selection.

Can you make a door with a Cat Flap in?

Yes we fit cat flaps and pet flaps in our doors. They are best fitted in PVC doors and we can fit in both plastic and glass bottom panels. These will be an extra charge.

What is the difference between French and Patio Doors?

The term French door applies to a pair of doors one left hand one right, which can open in or more usually out. Patio door is generally the term given to a door that slides on rollers to one side or the other. Both will give light into your home.

How secure are your doors?

Our doors are made to Secure By Design specifications. They are PAS 23/24 rated. They employ a 5-point locking mech and safety glass. There are additional options available such as laminate glass for extra security.

“As a tenant, not the property owner, I am well impressed!”

As a tenant, not the property owner, I am well impressed!
The product ‘speaks’ for itself, notably the child lock features & the double opening windows. My focus is with the installation Team of Ashley & Micheal who completed today. I cannot fault the quality of the workmanship, especially the finishing internally around the framework.
Its obvious to see that they both take pride in their work & also cleared up after, both in & outside. A job well done & much appreciated by my wife & I.
