How To Reseal Double Glazed Windows
How To Reseal Double Glazed Windows: A Rope Access Guide for High-Level Buildings
Double glazed windows are a staple of modern architecture, valued for their insulation, noise reduction, and energy efficiency. However, over time, the seals around these units can degrade, leading to condensation, draughts, and reduced performance. Resealing double glazed windows is essential to maintain their benefits—but what happens when your windows are several stories up, inaccessible by standard means? This is where rope access specialists like [Corded.uk](https://corded.uk) come in, providing a safe, efficient, and cost-effective solution to reseal windows at height without the disruption of scaffolding or cherry pickers.
In this article, we’ll explain how double glazed windows are resealed, why rope access is ideal for this task, and what the process involves for property owners and facilities managers.
Why Do Double Glazed Windows Need Resealing?
Double glazed units (DGUs) consist of two panes of glass separated by a sealed gap, often filled with inert gas. The perimeter seal keeps moisture out and the insulating gas in. Over time, exposure to weather, UV rays, and building movement can cause this seal to fail, resulting in:
– Condensation between panes (misty or foggy appearance)
– Reduced thermal insulation
– Increased energy bills
– Potential water ingress and damage to window frames
Prompt resealing is essential to restore performance and prevent further deterioration.
The Challenges of Resealing at Height
For low-level windows, resealing might be a straightforward DIY or contractor job. But for windows on upper floors—especially on commercial buildings, residential blocks, or industrial sites—access becomes a significant challenge. Traditional methods like scaffolding or cherry pickers are:
– Disruptive: Installation and removal can block entrances, pavements, or roads.
– Time-consuming: Erecting scaffolding can take days.
– Costly: Equipment hire and labour add up quickly.
– Inflexible: Not always feasible in tight or busy urban environments.
Rope access, as provided by Corded.uk, overcomes these challenges with minimal disruption and maximum efficiency.
The Rope Access Advantage
Rope access involves trained technicians using harnesses and rope systems to safely reach and work on difficult-to-access areas of a building. For window resealing, this method offers several benefits:
– Speed: Technicians can be in place and working within hours, not days.
– Minimal Disruption: No need to close off large areas, block access, or disturb building occupants.
– Cost-Effective: Lower equipment and labour costs compared to scaffolding.
– Safety: Rope access is governed by strict safety standards (such as IRATA), with technicians highly trained for complex environments.
– Flexibility: Ideal for buildings of all shapes and sizes, including those with limited ground space.
How Are Double Glazed Windows Resealed Using Rope Access?
Here’s a step-by-step overview of the typical process Corded.uk uses to reseal double glazed windows at height:
1. Assessment and Planning
– An initial inspection, often using rope access, determines the extent of seal failure and identifies any additional issues (e.g., frame damage, glass cracks).
– The correct materials and methods are selected based on window type and building conditions.
2. Preparation
– Rope access anchor points are installed or existing ones are inspected for safety compliance.
– The work area is cordoned off below to ensure pedestrian safety.
– Technicians perform equipment checks and safety briefings.
3. Access and Cleaning
– Technicians descend to the window using rope systems.
– The old, failed sealant is carefully removed using specialized tools.
– The window perimeter is cleaned to ensure the new sealant adheres properly.
4. Resealing
– High-quality, weatherproof sealant is applied around the window perimeter.
– For some units, external glazing beads may be refitted, or pressure plates tightened to restore the seal.
– Care is taken to achieve a neat, durable finish that matches the original installation.
5. Inspection and Finishing
– The new seal is inspected for continuity and adhesion.
– Any excess sealant is cleaned away, and the area is left tidy.
– Technicians descend, and the safety cordon is removed.
6. Reporting
– A detailed report, including before-and-after photos, is provided to the client.
– Recommendations for ongoing maintenance may be included.
