Double Glazing

Double Glazing

By far, double glazing is still the most popular glazing system used in the UK. With the benefit of lower energy bills, replacing all single-glazed windows with energy efficient double-glazing could save you around 235 per year on your fuel bills. All our windows are manufactured in our Climatec factory based at Southend, in Essex.

Triple Glazing

Triple Glazing

Triple glazed windows are even more energy-efficient than modern double glazing. The increased thermal insulation benefit is gained by the additional pane of glass and gas filled cavity. If you are looking to reduce your energy bills or reduce external noise, triple glazing may be your answer.

Aluminium Windows & Doors

Aluminium designed windows and doors offer strength, durability and are provide slim-lines, more glass area and less visible frame. Our aluminium windows and doors are constructed from superior materials to be maintenance free and to last decades rather than years. Ask about our colour range and slimline profile.



Climatec supply and install a wide range of secure, energy-efficient PVCu, Aluminium and Composite doors to fully compliment any property. Our door range includes French doors, Sliding Patio Doors, front Composite Doors, Bi-fold Doors and PVCU Back doors.



A carefully chosen and well-built conservatory or orangery adds value to any home and having a wide range of styles to choose from means that careful thought and planning should be the key elements to help you to make the right choice.

Climatec Home Improvements supplied a fabulous new bay window for me, at a very fair price and perfect, fast installation!

Supplied and fitted my new windows and B-fold Doors. From quote stage to installation we received a Top rate service and Climatec have since supplied windows and doors to family members of mine on my recommendation and they are as equally as happy as i am. Phil and Tony who fitted them were extremely polite and tidy and a pleasure to have in the house.

Climatec home Improvements fitted our uPVC flush fit windows as well as our aluminium bi-fold door. The products and service received were second to none. Would highly recommend the company and their fitting team. Great job. Very happy.

When designing our kitchen alterations we wanted something a bit different but it needed to be sympathetic to the cottage. We had an idea and the people at Climatec were fantastic in bringing this to life. We went with the Aluk sliding doors with the addition of bar grids which look fantastic and bring in so much light. From the designers to the surveyor to the fitters - cannot recommend them enough!

This company was recommended to me when I needed a replacement roof for our conservatory, they carried out the work to an extremely high standard and I found them totally reliable and would have no hesitation in recommending them to anyone who needs new windows or conservatories.

Composite doors give you the ultimate performance for security, energy efficiency and style. Being made up of multiple materials, they're extremely strong and keep intruders and the elements out of your home. With a highly insulating core, your heat retention is maximised, making these ideal as your entrance door. As well as offering a wealth of benefits for your home, composite doors have the wow factor. With an exterior GRP skin that's damage resistant, they perfectly resemble authentic timber.

We offer both double and triple glazing in the majority of our windows and doors. As well as keeping your home comfortable all year round, they will also keep your bills down and offer you beautiful views. Talk to us to find out what glazing is best for your home. We only use glass that keeps your heat in all year round. Including the effective Planitherm range, our glass uses an advanced coating which captures warmth from the sun to heat your home. This also reflects heat back into your home letting you rely on your heating less.

Casement windows are one of the most popular styles and it's clear to see why. A versatile and attractive design, they will suit any home. Available in both aluminium and uPVC, our casement windows are the perfect choice to brighten up your home. They will fill your home with light and can easily open to let some air into your home. Traditionally, these windows are recognised by hinges on the side but you can also choose from top hung windows to make them exactly the way you want them. Fire escape openers can also be fitted for your peace of mind.

Your entrance door is the first part of your home a guest will see so it needs to stand out for the right reasons. We offer a beautiful range of uPVC and aluminium entrance doors that will boost your kerb appeal as well as ensure your home is protected from intrusion and the cold. With so many styles available you can pick from our contemporary aluminium door collection or go for one of our period doors to suit those houses with a more traditional look. Choose from inward or outward opening, whichever gives you more space in your home.

Bay and bow windows offer an attractive change from the standard casement style. The bay window offers you more light and gives the illusion of extra space in your room which makes them ideal for the living room. Bay windows are three or more panes that angle out from your home, the bow style is similar but tends to have more windows that have a gentle arch. Both these styles can have side or top hung windows and are the perfect choice to add some kerb appeal. Our aluminium and uPVC bay and bow windows offer exceptional thermal and security performance making them a great choice for your home.
