Space Arc Engineering is an authorized distributor and applicator of D-Seal expansion joint systems across India. We supply, detail and install D-Seal Roof Seal — TPE on commercial, infrastructure and industrial projects — with technical selection support, project pricing and trained applicators nationwide.

Roof Seal TPE is Dseal’s flexible thermoplastic roof expansion joint seal, supplied in roll form to deliver UV-stable, weather-resistant sealing across roof and exterior joints.

Key Benefits

• Stays flexible across temperature swings, moving with the building instead of cracking.
• Excellent UV resistance keeps the seal sound under India’s intense sunlight.
• Roll form enables fast, continuous coverage over long roof joints.
• Weather-resistant TPE/TPV reliably blocks rain at roof and exterior junctions.
• Lightweight thermoplastic adds no significant load to the roof structure.
• Fewer joins mean fewer potential leak points across the run.

Applications

• Roof expansion joints on commercial and residential buildings.
• Exterior facade and parapet junction joints exposed to weather.
• Terrace and podium roof joints requiring flexible waterproofing.
• Industrial roofing with long continuous joint lines.
• Renovation and re-sealing of ageing roof joints.
• Mixed-use developments needing UV-stable exterior seals.

Features & Construction

• Manufactured from thermoplastic elastomer (TPE/TPV) for lasting flexibility.
• Supplied in continuous roll form for long, uninterrupted joint runs.
• Excellent UV and weather resistance for exposed roof and exterior use.
• Accommodates repeated thermal expansion and contraction movement.
• Suited to both roof joints and exterior facade or junction joints.
• Flexible profile conforms to varied joint geometries and transitions.

Technical Specifications

Installation Guide

1. Clean the joint and adjacent surfaces, ensuring they are dry and free of dust.
2. Measure the joint run and unroll the TPE seal to length, allowing for laps.
3. Position the TPE roll centrally over the joint along its full length.
4. Bond or mechanically fix the seal edges to the substrate per the joint detail.
5. Overlap and seal roll ends and direction changes to keep continuity.
6. Press the seal firmly into place and confirm full adhesion along the run.
7. Inspect the finished line and seal any terminations against water ingress.

Maintenance & Care

Inspect the Roof Seal TPE at least twice a year and after severe weather, looking for lifted edges, punctures or worn laps. Keep the joint clear of grit, foliage and standing debris so the membrane is not abraded or stressed during movement. Re-bond any lifted sections and patch minor damage promptly to maintain a continuous watertight line. Because the TPE/TPV material from Dhawan Associates resists UV and weather, a well-maintained seal stays flexible and effective for years in Indian conditions.

Roof Seal — TPE — Frequently Asked Questions

What is Dseal Roof Seal TPE?

Roof Seal TPE is a flexible thermoplastic elastomer (TPE/TPV) seal for roof and exterior expansion joints, supplied in roll form by Dhawan Associates under the Dseal brand.

What material is the Roof Seal made from?

It is made from thermoplastic elastomer, specifically TPE/TPV, a material prized for its flexibility, recoverability and strong weather resistance.

Is the Roof Seal TPE supplied in rolls?

Yes. It comes in continuous roll form, which allows fast installation over long joint runs with fewer joins and potential leak points.

How does the Roof Seal handle weather and sunlight?

The TPE/TPV compound offers excellent UV and weather resistance, so it stays flexible and watertight even under prolonged sun and monsoon exposure.

Can the Roof Seal TPE be used on exterior joints?

Yes. It is designed for both roof and exterior expansion joints, including facade, parapet and junction details exposed to the elements.

How is the Roof Seal TPE installed?

The joint is cleaned, the TPE roll is laid centrally over the joint, and its edges are bonded or fixed to the substrate, with ends overlapped and sealed for continuity.

How do I maintain a TPE roof seal?

Inspect it twice yearly, keep the joint clear of debris, re-bond any lifted edges and patch minor damage to keep the line continuous and watertight.

What is the difference between Roof Seal TPE and SkyBridge?

Roof Seal TPE is a flexible thermoplastic seal in roll form, while SkyBridge is a metal-covered roof joint system for 50-500 mm gaps. TPE suits flexible roll-applied sealing; SkyBridge suits rigid metal-cover joints.

Does the Roof Seal TPE accommodate building movement?

Yes. The thermoplastic elastomer flexes with thermal expansion and contraction, so it moves with the structure rather than restraining it.

Can Roof Seal TPE be supplied in custom widths?

Yes. As the manufacturer, Dhawan Associates can supply the TPE seal in widths and lengths suited to your specific joint requirements.

Who manufactures Roof Seal TPE?

It is manufactured by Dhawan Associates under the Dseal brand, a leading Indian producer of building expansion joint systems.

Where can I buy Roof Seal TPE in India?

Roof Seal TPE is supplied across India directly by Dseal (Dhawan Associates). Call +91 93109 97953 for pricing and project support.

Is the Roof Seal TPE certified?

Dhawan Associates manufactures to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 management system standards, covering quality, environment and worker safety.

Is TPE better than metal covers for roof joints?

It depends on the project. TPE roll seals excel at flexible, continuous exterior sealing, while metal covers like SkyBridge suit traffic-bearing or structural joints. Dseal can advise on the right choice.

Can Roof Seal TPE be used for re-sealing old joints?

Yes. Its roll format makes it well suited to renovation and re-sealing of ageing roof joints where a flexible, fast-to-apply membrane is preferred.

Does the TPE seal resist cracking over time?

Its UV and weather resistance helps it stay flexible and resist cracking far longer than untreated seals, especially under the strong sun common across India.
