Eliminating Thermal Bridging Around Windows

Understanding and addressing thermal bridging around windows is crucial for homeowners aiming to boost energy efficiency, lower heating costs, and improve indoor comfort. Simple Solutions 4 U specialises in the distribution of premium renders, plasters, and EWI systems, as well as expert plastering and rendering services tailored to eradicate thermal bridges and elevate your property’s performance. Visit our shop to explore our comprehensive product range.

What Is Thermal Bridging?

A thermal bridge forms when heat flows through a material or junction more rapidly than through surrounding insulated areas. Around windows, gaps in insulation, poorly detailed reveals, or conductive frame elements create paths for heat loss and cold ingress, leading to higher energy bills, surface condensation, and risk of mold. Learn more about thermal bridging in our blog.

Common Causes Around Windows

Discontinuous insulation in window reveals and jambs
Metal frames without thermal breaks conducting heat
Insufficient sealing between frame and wall substrate
Incorrect installation of EWI components creating voids
Uninsulated sill and reveal junctions allowing thermal bypass

Diagnosing Thermal Bridges

Identifying thermal bridges is the first step toward targeted remediation. Thermal imaging surveys reveal cold spots and heat leaks at window junctions, helping to pinpoint where insulation continuity is compromised. Our property assessments include detailed infrared analysis to guide the optimal EWI solution.

Assessing Your Property

Our professional building survey combines visual inspection with thermal imaging to map heat loss around windows, door reveals, and junctions. This comprehensive analysis informs the selection of the correct insulation board thickness, reveal panels, and accessory profiles. Read our case studies to see how tailored surveys drive effective results.

Advanced EWI Solutions

External wall insulation systems deliver an uninterrupted thermal barrier when specified and installed correctly. We supply pre-insulated window reveal panels, thermal break profiles, high-performance adhesive, and reinforcing mesh for a fully integrated finish. Quality through-coloured renders provide both aesthetic appeal and durable protection. Explore our render options.

Installation Process

Surface Preparation: Clean and prime substrate to ensure optimal adhesion.
Adhesive Application: Fix insulation boards around window openings using CT-84 express foam adhesive for rapid bonding.
Detailing Reveals: Fit pre-cut reveal panels or thermal break profiles to maintain insulation continuity at jambs and sills.
Mesh Reinforcement: Embed CT-325 glass fibre mesh into basecoat, focusing on corners and junctions to prevent cracking.
Decorative Finish: Apply through-coloured decorative render for a seamless, weather-resistant surface.

Benefits of Addressing Bridges

Up to 30% reduction in heat loss, lowering energy bills
Minimised condensation and mold growth through continuous insulation detailing
Improved indoor comfort with stable room temperatures
Enhanced property value and curb appeal with durable finishes
