Features

Made in Britain Accredited

Our sliding sash windows are sourced from a Made in Britain Accredited company. This guarantees a high quality product from a company that values professional and sustainable business practices. With stringent requirements for the company and the products it creates, you can be sure that everyone involved in creating your new dream window cares about the final product just as much as you do. 

Sustainable Timber Sash Windows

All of our timber products sourced through Glyngary are made from durable Accoya wood, a highly sustainable material made from Radiata Pine. This medium-density wood is treated with acetic acid to fill any air pockets within the wood, increasing its strength and making it weatherproof. This treatment, known as ‘acetylation’, transforms the timber, making it stronger than hardwood when the process is complete. 

The Radiata Pine reaches maturity at around 30 years, making it a fast-growing resource that is simple to replenish. Unlike other wood treatment options, the acetylation process is non-toxic, meaning that the wood isn’t hazardous throughout its 70+ year lifespan. 

Energy Efficient Timber Sash Windows

For enhanced energy efficiency and thermal comfort, a timber sliding sash window is the perfect choice. With enhanced double glazing and a weatherproof frame, you can enjoy warmth and comfort in your home with less need for central heating, helping you save on your energy bills. 

With our spiral weights, your window can achieve u-values of 1.2 W/m²K with double glazing, with the change to lower it even further to 0.77 W/m²K if you choose triple glazing. 

Lead-weighted windows, the more traditional option, can achieve 1.3 W/m²K when fitted with double glazing, with triple glazing taking it down to 0.9 W/m²K.

How To Stop Window Condensation

Window condensation is a widespread problem for homeowners across Bristol, Bath and the surrounding areas, particularly during autumn and winter. It develops when warm, moisture-heavy air inside a property comes into contact with colder window surfaces, causing water droplets to form on the glass. Although condensation may appear to be a minor inconvenience, prolonged exposure can lead to mould growth, damage to window frames and surrounding walls, and a decline in indoor air quality. Understanding how to stop window condensation is essential for protecting both your home and your health. What Causes Condensation on Windows? Condensation is most common in homes with poor insulation and limited ventilation. Older properties found throughout Bath and many parts of Bristol often still rely on single glazing or inefficient double glazing, which allows internal glass surfaces to become very cold. Everyday activities such as cooking, bathing and drying clothes indoors increase humidity levels, and without adequate airflow, moisture settles on the coldest surfaces in the room, which are usually windows. While opening windows and improving ventilation can help, upgrading your glazing is the most effective long-term solution How Casement Windows Help Reduce Condensation Modern casement windows are one of the best ways to prevent condensation forming on windows. High-performance casement windows from Panoramic Windows use advanced double or triple glazing to keep internal glass surfaces warmer, reducing the temperature contrast that causes condensation. For homes across Bristol and Bath, this results in drier windows, improved comfort and better overall energy efficiency. Casement windows also allow excellent ventilation control, enabling homeowners to release humid air quickly when needed. Their tight seals prevent draughts while still allowing fresh air circulation, which helps regulate indoor moisture levels. Alongside condensation reduction, casement windows improve thermal efficiency and reduce heating costs, making them a practical and visually appealing upgrade for both modern and traditional homes. Secondary Glazing Secondary glazing is an ideal solution for homeowners who want to reduce condensation without replacing original windows. This is particularly important in listed buildings and conservation areas, which are common throughout Bath and central Bristol. Secondary glazing involves fitting an additional pane internally, creating an insulating air gap that keeps the original window warmer and significantly reduces condensation. This solution is highly effective at improving thermal performance while preserving the character of period properties. In addition to condensation control, secondary glazing improves sound insulation and helps lower energy bills. For homeowners seeking a discreet, planning-friendly solution, secondary glazing from Panoramic Windows offers long-lasting benefits. Aluminium Windows Aluminium windows are a popular choice for contemporary homes and renovation projects across Bristol and the surrounding areas. Modern aluminium window systems are designed with advanced thermal break technology that prevents cold from transferring through the frame. This ensures internal surfaces remain warmer, reducing the likelihood of condensation forming on both the glass and frame. In addition to their excellent thermal performance, aluminium windows provide slim sightlines and larger glass areas, allowing more natural light into the home. Their durability, low maintenance requirements and resistance to corrosion make them a long-term solution for homeowners who want to address condensation while achieving a modern, minimalist appearance. Why Choose Panoramic Windows in Bristol and Bath? Choosing the right window solution is only part of the equation; professional installation and local expertise are equally important. Panoramic Windows has extensive experience supplying and installing high-quality casement windows, secondary glazing and aluminium windows across Bristol, Bath and nearby areas.

Keeping Your Conservatory Warm in Winter

At Panoramic Windows, we understand that conservatories are a wonderful addition to any home in Bristol, Bath, and the surrounding areas, providing a bright, peaceful space to relax. However, as winter sets in, many homeowners struggle to keep these rooms warm and comfortable. Poor insulation can make conservatories chilly and drive up energy bills, but with the right solutions, you can enjoy your space all year round. The Importance of a Conservatory Roof Your conservatory roof is one of the most important factors in keeping the space warm. Traditional glass or polycarbonate roofs often fail to retain heat effectively, leaving rooms cold during the winter months. Upgrading to a thermally efficient roof can transform your conservatory into a cosy, energy-efficient space. At Panoramic Windows, we specialise in replacement conservatory roofs designed to improve insulation while enhancing the aesthetic appeal of your home. Upgrade to a Thermally Efficient Roof Installing a modern, insulated conservatory roof is one of the most effective ways to reduce heat loss. Our replacement roofs are specifically designed to enhance warmth and minimise energy usage, meaning you can enjoy your conservatory even on the coldest days without relying on constant heating. Solid or tiled roofs not only improve insulation but also add a stylish finish to your home. Our lightweight tiles come in a variety of colours and styles, allowing you to match the character of your property — whether it’s a historic home in Bath or a modern property in Bristol. Enhancing Insulation Throughout the Conservatory While the roof is crucial, whole-room insulation can make a significant difference. Double or triple-glazed windows, insulated flooring, and tightly sealed frames help prevent heat from escaping. Homeowners across South Gloucestershire, Wiltshire, and Somerset can benefit from our guidance on the best glazing and insulation options to maximise thermal efficiency. Keep Your Conservatory Warm with Double or Secondary Glazing Upgrading to new double glazing or secondary glazing is one of the most effective ways to improve the thermal efficiency of your conservatory. Modern double-glazed windows trap heat inside, reducing draughts and keeping your space cosy during the coldest winter months. For homes in Bristol, Bath, and the surrounding areas, secondary glazing can be an excellent option for older conservatories or listed properties where replacing the existing windows isn’t possible. Not only does glazing enhance warmth, but it also improves sound insulation, reduces condensation, and boosts your home's overall energy efficiency. At Panoramic Windows, we guide homeowners through the best glazing options, helping you choose windows that complement the style of your conservatory while delivering long-lasting comfort. With high-performance glass and expert installation, you can enjoy a bright, light-filled conservatory that stays warm year-round without driving up your heating bills. Regular Maintenance Is Key Routine checks of your conservatory can prevent heat loss caused by draughts, leaks, or damaged seals. Timely maintenance not only keeps your conservatory warm but also protects your investment and extends its lifespan. Conservatory Roof Prices Bristol If your conservatory feels cold or underused during winter, it may be time for a roof replacement or insulation upgrade. At Panoramic Windows, we offer expert advice and high-quality replacement conservatory roofs for homeowners in Bristol, Bath, and surrounding areas. Enhance your home’s comfort, reduce energy bills, and transform your conservatory into a warm, welcoming space year-round.

Is Your Period Home Losing Heat? Why October is the Month to Switch to Energy-Efficient Sash Windows

It is that time of the year where the colder evenings are drawing closer and the unavoidable moment of switching on your central heating is near.  But as you turn your heating on, a feeling of disappointment immediately follows as the warmth quickly vanishes and you feel a ghostly draft chilling your beautiful, historic home. This coldness is common in charming period properties, particularly due to sash windows being the culprit.

To distinguish how your home is losing heat, we recommend that you start by finding the symptoms of a heat-leaking window. These can include: ratting when it is windy, excessive condensation and mould build up, and having to turn the thermostat up just to feel comfortable.  Replacing your inefficient windows is important, especially in October. If you are unsure if your windows are performing well, contact us and we will be happy to provide you with some expert advice.  The Panoramic Solution: Performance that Preserves Here at Panoramic Windows, we provide sash windows that are specifically designed to look authentic while delivering top-tier performance.
