Popular Types Of Uk Windows

Sash Windows

Traditionally, sash windows were made from timber, soft and hardwoods, they are now made from various materials like virgin uPVC. This means that they can be just as energy efficient and safe as other types of windows. Box sash windows also come in many different styles.

Sash windows open and close via a sliding motion. This involves two sash panels vertically or horizontally sliding to create an opening. You can choose a sash window that only has a bottom or top sliding panel, or more traditionally, one that enables both sash panels to slide.

Casement Windows

Casement windows open by a hinge and they usually open and close just like a door. Casement windows are fairly energy efficient due to their virtually airtight lock and compression seal. Casement windows were popular in Victorian & Edwardian times and are still used a lot in newly built homes.

You can get casement windows in various different materials such as timber and uPVC.

Overhaul & Draught Proofing

Overhauling & Draught proofing helps revive old windows so that they work as intended.

  • Replace broken or damaged sash cords.
  • Re-weight and balance your sash windows so that they run as intended.
  • Draught seal your windows to stop leaks and improve efficiency.

In order to draught proof or draught seal, we will seal gaps that have formed around your window and frame. If your windows are not draught proofed this may lead to dust, dirt, cold air and noise entering your home. Draught proofing also helps with the smooth running of your sash windows. It also means savings on energy bills by keeping the hot air in, and the cold air out in the cold months.

What Our Clients Say

Stephen with Sash Windows did very good work – was responsive to the first call and in giving the estimate, and scheduling. Prompt, efficient, fast workers but without losing good workmanship – so important! Careful with the wood surrounds. Cleaned up well after the work was completed. I could well recommend this firm. I had insulating strips installed.

Frequently Asked Questions (FAQ)

What is a sash window?

Sash windows are special windows that can be opened vertically. They are generally found in traditional buildings and architecture and have become part of modern architecture. Sash window manufacturers offer several designs, sizes, and materials.

The overall sash windows cost in the UK depends entirely on the size, material, glazing, and other customisations you need. Our team can estimate the cost of installing sash windows on your property. Rest assured that the price will be budget-friendly, as they come with a host of benefits.

Sash windows are low maintenance, provide safety and security and look beautiful. These windows are energy-efficient, lowering your energy bills during summers and winters. They are also perfect from the point of security to prevent intruders from entering your house and protecting small children. They last for years, thereby being a cost-effective option.

You don’t need extensive planning for sash windows, but little knowledge of measurements, timelines, and other details is required. The sash window experts will cater to all your needs for replacing or repairing old sash windows. They will also take care of sash window film and sash window installation.

Many theories and interpretations exist for the name “sash”. Some credit the Dutch, while others suggest that natural philosopher and architect Rober Hooke invented it in the 17th century. Others say “sash” is from the French word for frame, which is “chassis”.

Upgrade Existing Windows To Double Glazed

You can upgrade your old sash or casement windows with double glazing to improve their energy efficiency.

Not only does it help reduce your energy bill, but double glazing also reduces noise pollution.
You can even add Acoustic Double Glazing to further improve your internal sound quality.

We only use materials of the highest quality and our years of experience means that premium quality doesn’t always mean a premium price. As a family-run business, we never compromise on quality & service.
