Replacement Double Glazed Sash Windows in London – Manufactured to perfectly replicate your existing period windows!

Replacing your single glazed sash windows with double glazed sash windows can add an additional thermal barrier when combined with our draught proofing service.

If you are having your sash windows repaired, refurbished or restored then you will also have an option to replace the single glazed sliding sash windows with new hardwood double glazed sash windows.

This will obviously add significant costs to your restoration or renovation price, but the benefits will be noticeable when the cold weather sets in.

Sash window draught proofing alone will normally be more than enough of a improvement as most of the heat lost through sash windows is from the cracks and gaps on the sliding runs of your windows.

Once the windows have been fully draught insulated simply drawing one’s curtains will provide you with pretty much the same if not better thermal protection as double glazed sash windows, the downside is though that on a beautiful winters day you will need to keep your curtains drawn to maintain he full benefit.

If you have retro-fit double glazed wooden sash windows fitted into your original box sash frames combined with a full refurb of the box and draught stripping you will achieve excellent thermal protection whether the curtains are drawn or not.

Costs involved can be quite high compared to simple refurbishment and draught stripping and anyone who tries to tell you that you will get a return of investment from reduced heating bills may indeed be right but they probably won’t tell you that it could take over 500 years to see it!

We do not use the reasoning of return of investment from a reduction in heating bills as the maths simply does not add up in our book. However, if you wish for a warm cosy home with reduced energy bills then double glazed sash windows combined with draught proofing is definitely worth considering.

What To Know About Double Glazed Sash Windows London Manufacturers Offer

Double glazing consists of two glass sheets with a gap in between. This gap is usually around 16mm and its job is to create an insulation barrier for retaining heat. Some manufacturers fill this gap with gas for utmost energy efficiency. If you live in an older home and are looking for double glazed sash windows London companies will offer you plenty of options. But before you start looking for such providers, take a look at some of the benefits of double glazing installation.

Energy rated windows will have the u-value displayed on their label. This label measures how easily heat can pass through the material. Window frames that let more heat escape have lower u-values. A replacement sash window should be more airtight than the original frames so that condensation does not build up in your home.
If your home suffers from lack of ventilation, look for replacement sash windows with double vents built into the frame. This will control the ventilation to some level. However, if you start seeing condensation around the window sills, this may indicate a damp problem. Damp occurs when the house has inadequate ventilation, not enough heating, and lack of insulation. If you notice damp in between the panes, it is likely that the seals are broken and the entire units must be replaced.

If your home is a listed building or you live in a conservation area, you may be faced with some restrictions on what you can do to the exterior. There are many insulation options for historic homes including heavy curtains, secondary glazing, and shutters. However, it is best to check with your local council before you make any changes to your home.
Listed homes have restrictions on what can be changed on the outside, and at times, on the inside too. Old sash window frames cannot be changed unless you seek permission from your local council. This is because historic homes need to be protected for their appearance as well as materials that are used to make them. Double glazing is ideal for insulating old homes and in most cases, permission is granted for their installation.

Sash window units are some of the most common features in period homes and are highly desirable. These units consist of two vertically sliding panes that are made of single glass and often have poor insulating properties. To improve your window units, there are a number of alternatives including double glazing.
By opting for an extra glass sheet on your units, you will improve security in your home. Single panels have poor locking systems and are easily breakable by intruders. On the other hand, if you install an extra panel of glass, you will benefit from a strong structure and your home will be safer.

One of the main benefits of having an extra sheet of glass on your units is the improved energy efficiency. These units are extremely effective in retaining heat and keeping the cold air out. As a result, you will end up using less heating in winter and save money on your utility bills.
When these types of frames have the ability to insulate the property, they will keep you warm and more comfortable in your home. You will no longer see signs of condensation and you will not need to constantly switch your heating on and off. The indoor temperature of your home will be stable and comfortable at all times.

Window manufacturers offer traditional designs with modern features so if you are an owner of a historic property, you have plenty of options available to you. Just make sure you choose a design that fits in with the rest of your property. One simple and convenient way of finding the right manufacturers is by referring to the Web.
Reputable manufacturers offer beautifully designed and crafted window units that are aesthetically appealing to listed properties. Although it may cost you more to replace your historic units from single glass to two-layered glass, it will be a long-term investment as you will end up saving money on your heating costs.
Your home will be quieter, free of mould, secure, and comfortable. What is more, you will enhance the value of your property.
